Hi,
My ZUK Z1 european version has just arrived and I am noticing that it cannot take the 5Hz wifi when there is some distance in between. If it does it, it disconnects in seconds. It does connect to the 2.4Hz g without too many problems (some times even not this one). If I put only 5Hz networks, the same happens. Sometimes it doesn't see the signal at all.
This doesn't happen when I am next to the router. So, since the 5Hz deteriorates more with distance (AFAIK) what I'm describing shouldn't be surprising. My doubts are because with the nexus 4 (Android, not cyanogen) it grabs the 5Hz without any problem at exactly the same long distance (2 thin walls, few furniture in between), and I find very unlikely that the wifi chip of the nexus 4 is superior than the one of the zuk z1.
UPDATE:
It is very strange. With the ZUK, in front of the router I get 110 Mbps (5Hz, n-only), when I move to the room in question I get 3-4 Mbps only, so about to be disconnected.
With the nexus 4 (same 5Hz connection obviously), I get 50 Mbps when I am in front of the router AND when I am in the problematic room. How is that possible?
If I test connecting to the 2.4Hz (b,g,n), the nexus 4 gives the same 40-50 Mbps no matter the distance. I have to go to a very "protected" room to see a drop to ~15 Mbps, again showing no difference between the two bands.
If I test with the zuk, it gives 20 Mbps, if I move to the very "protected" room, I see a drop down to 0.3 Mbps
So, it is like the wifi is much better if you're in front of the router, otherwise is significantly worse? Is that feasible? Can it be a software problem?
Hello! first of all excuse my bad english
I received today me ZUK 1 and im having the same trouble, its impossible to use wifi without problems when you are in a different room from router, and especially when you put the smartphone in horizontal position ,grab it with two hands and cover the superior part with your hand, when i do this i simply lost the connection even if im in front of router. I come from HTCmania, a spanish forum of smartphone and we are few people with the same problem and is very frustating that there is no solution and noboy in Lenovo or ZUK says nothing about this trouble.
Me too. Wifi is very very very bad if you hand is in the top (camera zone). Horizontal, vertical, it does not matter if you cover the area with his hand, zasss wifi dies.
Sorry my very bad english.
Same problem here
I have the same problem as described. I have not noticed if my hand position affects it. My OnePlus one and my Sony Xperia Z1 compact both manage to hold on to the wifi in my bedroom albeit less than full signal. The Zuk z1 just keeps dropping off and sometimes doesn't find the wifi.
Have anyone contacted Zuk about this? Mine was bought through Spanish eBay but seems to have been sent to Spain from Germany.
Following the thread for a solution as this problem is a definite dealbreaker.
Daniel
Uau, I've just tested it and while it is unrelated to the problem that I say (this is, the ZUK receives the 5Hz band very bad it seems) it is completely true. While doing a wifi test (Wi-Fi Deadspot app), connected to the 2.4Hz, from 55 Mbps if I put the hand over the top part of the mobile it drops to 30, if I put the hand in the middle part of the back zone it drops to <5Mbps!!
*Having it over a table doesn't make a difference for me.
UPDATE: The measurements from this app seem very variable, based on other comments it doesn't seem to be related to the software but to the ZUK. Now the 5Hz band gives excellent results from the room where before it couldn't even see the wifi.
So it does seem capable, but VERY unstable I guess. Is this hope for waiting a software-based solution? Or we should mark this phone as a wifi-less phone ...
(damn ~_~ they sure knew about this from the units sold in China)

2,4 ghz
Just checked and it turns out that my wifi is on 2,4 ghz. So I guess the conclusion is that the problem is unrelated to the frequency.
There are two problems:
Problem 1- Wifi drops when your hand is on the top of your phone, irrespective of the frequency
Problem 2- Wifi in the 5Hz is very unstable and/or much worse when compared with a nexus 4 phone (relevant provided it is an old phone), related to the frequency (or it seems so at least)

I didn't noticed anything before i read this and tried to put my hand on the upper part of the phone : my WiFi connection instantly shut down even if I had 3bars over 4... So yeah there's a real issue with the WiFi antenna here :S (first real drawback I have with this device...)
Apart from that, I owned a Nexus 4 too just before this device and I personally have a better WiFi reception on my Zuk Z1 (one more bar for both 2.4 and 5Ghz bands)
Does the same happen with ZUI os?
I also have a Wifi problem with the international version of Zuk Z1.
Testing the Wifi with the App "Wifi DeadSpot" in both the Zuk and a Oneplus 1, the results are:
2m far from the router:
OnePlus1: 38Mbps (GOOD)
Zuk Z1: 9Mbps (AVERAGE)
10m far from the router:
OnePlus1: 22Mbps (GOOD)
Zuk Z1: 0.45Mbps (POOR)
In both cases the phone is in vertical and without touching it (holding it near the camera apparently really makes Wifi coverage worst)
If the Zuk is in horizontal position, the Wifi signals is also worst: 0,5-1 Mbps at a 2m distance.
I tried resetting the Zuk to factory settings and the results are the same, so I don't think it's a software issue. Could be a manufacturing defect or just a cheap wifi chip?
Wifi on the ZUK Z1 is better than Note 4, S6, Xperia Z3+ and Mi Note.
On some positions I don't get Wifi, with the Z1 2/4.
Speed up to 50Mbit/s over 2.4GHz. With 5GHz about 120 Mbit/s. I don't need more.
Hello, I received my EU Z1 today and I'm coming from a Nexus 4 too. I don't have any trouble with 2.4ghz WIFI, the connection its perfect two stories under the router and I can say its as good if not better then the Nexus 4 holding it in any way. I think you got defective devices.
I hope your are right.
I'm considering buying this device. Would be great if other people could tell about their wifi reception.
Same problems here, with cyanogenos, didn´t test ZUI os.
I´ll posted the bugs on cyngn forum here: http://community.cyngn.com/t/some-m...lash-flashlight-poor-wifi-back-button-led/208
But not sure if its a software or hardware issue, i guess hw.
It's pretty random...
If i have the phone 3-4m from 2.4ghz router through a wall:
Keeping the Z1 in the same position, without touching it, WiFi reception varies from 2-4Mbps to 40Mbps (from test to test in Wi-Fi deadspot app). Can't predict when I get which speed. Mostly it's very low, though.
Disconnecting and reconnecting sometimes helps but mostly it doesn't. My old Huawei Y300 has a solid ~18Mbps when tested at the same spot.
Then again also the phone reception randomly drops from 3 bars to 1 to just go back up to 3 all within 1-2 seconds. (which might be unrelated but coincided with having higher Wi-Fi speeds)
Here's hoping for a software bug....
Cheers.

There is one thing that is rather consistent though:
Whenever the display turns off during the Deadspot test, WiFi drops e.g. from 40Mbps to ~8Mbps. I first observed it by chance and then switched off the display on purpose several times while the app was running...
In the WiFi settings it's set to always keep on, so that shouldn't be the issue...
@tuatara42
I think i noticed sth similar, i had map downloads for navigation, around 2gb of data, it was half done in a few minutes but when it gone into standby mode and i woke it up 10 minutes later it barely progressed, so that means the wifi must have been slower.
That gets me a bit of hope that it´s "just a software problem".
I just tested the speed right next to the router:
Same speed, no improvement, 1-4Mbps.
Full speed with the Y300.
Actually I'm pretty sure WiFi was much better in the beginning, before the latest COS updates...
COS could be part of the problem, with CynaogenMod on my old phone I have the same problem with wifi speeds when the screen is off.
I just did a rough test using Wi-Fi Deadspot. At about 7.5m, through four very solid brick walls, from my 2.4 Ghz router I got 32.49 Mbps with my Z1, and 27.74 Mbps with my old N4. So WiFi is fine for me.
Which COS12.1 version are you on?

Surprise me that I read nothing about the poor receiving quality of the Hermes when I one meter away from the router the signal drops down dramatically with 50% and after ten meters I read only 10% or something is there something to do about this? Maybe a bad antenna inside the Hermes or Faraday effect?
Any suggestion is welcome or am I the only one with this matter.

I'm afraid the TyTn (Hermes) does not have a strong reception on wifi. Fine up to 10 metres and if not too much in the way upto 15 or so. Ok generally in and around normal house but if it's Buckingham Palace not too hot. Just the compromise we pay for having to pack in allthe other features I'm afraid.

I believe part of the problem is the antenna placement. While I don't know exactly where the antenna is located, I do know that when the device is held in your hand it has a considerable lower receive signal strength (as much as 10dB).
Give it a try. Set the device on the table and see what you measure. Then hold the device in your hand and see the difference.

Your right. The antenna is along top edge. When in landscape your left hand tends to obscure it.

The WIFI reception on these devices is exteremly horrible. There must be a problem in the design, as it don't do more than 10 meters. We have a Andes in the house as well and it has no problems at all with wifi reception.
There must be a fix out there. I purchased this device specifically for the wifi .
have you noticed the connector for spar external place on the back of the TYTN? an is found rubberizes near the camera. I have attentively looked at the photos of the inside and I believe that this is related to the form radio and not to the wifi.
I would like so much to realize a connector wifi for external spar (you see PSP wifi connector) even replacing that connector radio with a wifi and connecting a cable on the chip wifi TNETW1250.
the welding of the cable should be made on the chip TNETW3422M.
Is there someone who has photo more detailed of those that are on the forum of xda?
Have y'all tried the Best Performance setting?
I have not used Wifi, nor will I ever (that is what 3G is for - since 3G is faster than my DSL connection...), but others have reported that changing to Best Performance helps...
I had three TyTN's and the last one had a horrible WiFi reception....10 meters at best. I had a Loox 720 (from a friend) for reference...with this PDA I could walk about 50 meters before reception became unusable. When it comes to WiFi reception this device has a major production tolerance. It makes me wonder if there is some kind of QC over there at HTC. My devices shouldn't have shipped in the first place.
b.t.w. I used all available settings and at in economy mode reception was even worse....signal meter at 30-40% only a few feet away from my wireless router (my reference Loox... 100%!!)
worst of all...instead of fixing it they just release a new device.

It's a curious thing - yes I get good reception up to 15 meters then drops off badly. BUT if I'm driving around with wifi on it detects an endless stream of home networks that in many cases must greatly exceed 10/15 meters.

In my opinion I think you correct with this setting only the interval of the cheksum when connected and not the sensivity of wifi receiver.
The one thing that's keeping me from fully enjoying my new Nexus 4---hassles with radios, both wifi & cellular.
1) On my home wifi network on all devices except the Nexus 4 I see solid, constant download speeds of 25Mbps. My Nexus 4 consistently only gives me 4-6Mbps. If I disconnect/reconnect sometimes I can see speeds slightly higher than that, but only temporarily. This isn't generally a huge deal because 4-6Mbps is fast enough for most things on a phone, it just bugs me that every other device in the house gets 25Mbps.
2) Of bigger annoyance is my cellular data connection, it drops off multiple times per day. The cellular signal strength indicates full bars, along with the 'H' icon indicating I'm connected to T-Mobiles HSPA+ network. Voice still works fine but the data connection is dead--nothing will connect--Speedtest, maps, Google Search, Facebook, etc. This forces me to either turn on/off Airplane mode or reboot the phone completely to regain my cellular data connection. On my previous SGS2 I never experienced this issue. It drives me nuts to not be able to pull up a phone number, directions etc at the times I need it most.
Does anybody have any similar experiences or suggestions on how to remedy these issues?
Edit---FYI I'm fully stock but rooted. 4.2.1 update not yet applied.
1) Check APN settings and make sure your account is properly provisioned by calling T-Mo CSRs. I had a similar issue with my Nexus One back in the day that was fixed with a reboot after they reprovisioned my account.
2) Flash factory image, in case it was a bad flash of the radio. It happens.
3) If 1 & 2 fails, or you don't want to try #2, call the Nexus hotline and get yourself a replacement.

Called TMobile and had them reset my account, I'll keep an eye on it the next couple of days.
Right now I'm downloading a cached Google map via WiFi and it is slooooow.
I also notice on edge the signal is inconsistent.
Hi
The Wi-Fi issue is something happening to others, seems to be a driver bug.

Wifi connectivity is my biggest gripe. I'll step 6 feet away from my router and I lose a bar. A couple rooms away I fluctuate between 1 and 0 bars.

Did you ever find a cure for this? I am having the exact same issues on my O2UK Nexus 4, anytime I want to use the data connection its almost guaranteed not to work and involve reboots, Airplane mode on and off etc
Im having the same issues. My data just drops wifi and cellular. I dont get full signal wifi or cellular. I live in india and flashed the latest .54 which was released in india recently. I managed to at least get cellular data going but my strength still low and data drops still on both wifi and cellular. Its super frustrating. Any ideas?
try reflashing the OS on your phone and try changing the wifi channel on your router.
changing the channel on my wireless router really helped signal to all of my devices. there may be lots of interference on the channel you're on.

I may reflash OS but i just got the phone today so ill slow down a bit. I flashed the radio one would think that would be enough? Anyway I have many other devices on my wifi without an issue and i used wifi analyser and theres no overlap with other routers and i experience this on 2g 3g and wifi so it looks like some modem problem. Unfortunately the phone was bought 3 months ago in the States and im here in india so im kind of stuck
There are known issues with the Nexus 4 wifi speeds slowing for no apparent reason. Also, known issues with the LOS (loss of signal). You can find information and bug reports on both of these issues.

Did a full flash from scratch. No progress. Also i went to my friends place and signal was perfect for like 4 hrs straight but every other place ive been since has seen choppy signal.

Pretty bad. I ran a test a few weeks ago and I can go up to 450 feet from my router (old Linksys) without a problem, and after that it gets iffy, and finally disconnects at 500 feet. I am seeing an average of 20 Mbps on wifi. Now if I can only get my cellular connection (non-wifi) to go faster than 1 Mpbs max I would have a usable phone.
I have a slightly diff issue.
If I reboot my phone, I connect to my router no problem. If I turn wifi off (to save battery) and then turn it back on.... it shows my AP's as out of range.... but I do see my neighbours AP's. I also have an N10 with has no issues at all with wifi (and none of my other divises have issues either).
When I bought the N4 they seemed to be having an issue with it when setting it up.... but I was not paying close attention. I am wondering if I have a bad phone on top of the "normal" wifi issues that other are experiencing.
Think I will revert back to stock and swap it for another phone to see if I can at least just turn off / on the wifi rather then reboot to connect (how sad is that?)

HI. I had this WiFi problem since I bought the phone like 6-7 months ago.
My previous phone was a Nexus 4. It had good wifi reception. From my apartment I could find like 6-7 routers with +2 signal bars.
My Lg G2 sees only 3 routers, mine and 2 others that are at 1 signal bar or sometimes no signal. I tried to flash other basebands but no improvment. I tried flashing other ROMs.
I now tried to lift the little conectors on the back cover and put a little piece of paper under so i'm sure they connect (i don't know if that's how wifi works because it's working the same with or without the back cover).
What else should I try? Is there something to do or every G2 has signal problems?
I might have a solution for you...

I had a similar problem with my G2. The old phone (Optimus 3D) had good and strong wifi signal. With this one, from the first day to connect to home network, I had connection problems and all I had to do was to set to one network mode (and only one - I use G), on a single channel (give it a low one - 1 to 6) and a 20 Mhz band channel. And guess what: I can have a clear and strong enough (plus stable) from down the street, while my flat is at the third floor.
Please try to modify your modem/router settings as stated before and let me know the results.

My router works fine. I have it on G/N 20Mhz Channel 5. I work installing internet antennas on top of buildings so I would like to access the routers from far away.
Another question. What's the purpose of the gold connectors on the back cover?I have like 3-4 pairs. My wifi, network and gps work with or without the cover. No difference.

You must have only one type of connection. Or at least in my case is so. I have only G, not mixed one. As for back cover connectors...I have none. Stock back cover, gold edition of D802.

Hey guys, on my ZTE Axon 7 A2017G, I'm having really bad WiFi issues.
I've attached some screenshots, but overall it seems like the WiFi keeps dropping out randomly.
My WiFi is not at fault here, I have a 30 Mbps connection and it has full range where I'm sitting, (5-10 metres from router) and there is no interference.
I do believe this to be a faulty phone, but if anyone has any suggestions please do help. I do still have this covered under warranty, so I can return the phone if needed to.
:good: :crying:
edit:
also for some extra information, the two arrows next to the WiFi icon are not always present whilst using the phone on WiFi, and when they are not present, the phone's apps will say no WiFi and if I check the settings app, it says under my network's name: Connected, no WiFi whilst there is full connection and I would have to forget my network and reconnect again.
I have an A2017U and it also has unreliable radios. My WiFi stats show the AP being weak and about 50m away. It suddenly dies and comes back saying it's a strong signal 4m away. Run a WiFi analyzer on the Axon 7 and another phone at the same time. The Axon 7 will show APs randomly fading out while the other phone shows steady signals. I recommend returning it under warranty. You might get another phone that dies less often and ZTE will lose a bit of money for not maintaining their flagship product.
Alright, thanks I will try the WiFi analyzer and return the phone under warranty.

So, I tried the WiFi analyzer with my zte axon 7 and a family member's galaxy s8 and both phones show around the same signals for the various APs and both phones randomly phase out APs at around the same time (probably due to weak connection, because its the neighbours WiFi) and so I'm really confused to what the problem is. @kevinmcmurtrie
My Axon 7 has the radios just drop dead. One common cause is that it wants to switch from 2.4 GHz to 5GHz shortly after waking up. It can roam fine but band switching kills the connection for about 10 seconds. Other drops are a total mystery. A WiFi analyzer shows APs randomly vanishing or muting for a while then coming back, with no relationship at all to real signal strength. Same goes for the cell radio. It loves dropping to a legacy EDGE tower when there's plenty of strong LTE signals around. Putting the phone in my pocket kills the cell data and it never comes back until I cycle airplane mode.
I've seen this on three Axon 7 phones. I have two and one was replaced, for a total of three. The second phone became stable when LineageOS was put on it - no drops, no vanishing APs, no EDGE, no missing cell data. I'd use only LineageOS if WiFi Calling was supported.
Hi all, just picked up a Tab S5E today - love the screen, built quality etc. What I don't love is the Wi-Fi performance. I'm left very confused.
I installed Android 10 right out the box and did a clean reset - after which my link speed in Wi-Fi settings shows 86 mbps throughput. For reference, my other phones (Oneplus 5 - 3 years old and Oneplus 8 Pro both show 866mbps receive and transmit speed).
When right next to the router I get a max of about 150mbps, with an average of 80mbps on Speed Tests - This is the case whether holding the tablet or not. When about 5 metres away through a wall this goes down to 45-55 Average, in comparison both phones show around 280-330 average.
When right next to the router with my other phones I get my networks full download which is 550mbps.
I understood before purchasing that if holding the tablet in the bottom left corner when in horizontal position (camera on the left) you are likely to lose signal - potentially mitigated with using a case. However, by wrapping my hands round the left antenna, on average - the speed increases to around 150-170 - odd...
When attempting to put pressure on the antennas from both ends and firmly wrapping my hands around the tablet, I do not see any network connectivity issues relating to dropouts and the WiFi bars remain on 5.
Honestly not got a clue what's happening here, either who have decently fast connections don't big this up online, or this is just a weird hardware fault with my unit.
Pretty disappointed. If anyone has any advice / screenshots of their speed results higher than this - I would greatly appreciate this, in which case I will definitely pursue a replacement device. I can't accept that in 2020 a device cannot achieve full 5.8ghz WiFi speeds when directly next to the router.
There is nothing wrong with your device. The maximum WiFi speed on the Galaxy Tab S5e is around 160 to 180 Mbit/s. I didn't expect this either when I bought this model and it is also a major bummer for me.
The device supports 802.11ac, but unfortunately Samsung only put a single antenna into it which limits it to a single MIMO stream (on a 80 MHz channel that gives you theoretical 433 Mbit/s throughput, which of course no device will ever reach). I would expect something around 220 Mbit/s with this configuration, but somehow the maximum speed I get with this device is only around 160 to 180 Mbit/s. It is not only the speed that is bad, it is also the signal strength that is exceptionally bad compared to all my other devices.
Your phones and other devices probably have two antennas and support 802.11ac with 2x2 MIMO which gives you theoretical throughput of 866 Mbit/s and around 500 Mbit/s in practice.
Thank you for your reply. I just received a replacement unit and tested before updating to the Android 10 update. There was indeed something wrong with that previous device as the link speed shows 433mbps and I consistently got 280-295mbps download.
However, I just updated it to Android 10 - now it's completely gone again. Link speed 87mbps and downloads of 20-70mbps. This is most definitely a software issue which I'll be contacting Samsung about.

I also got a WiFi issue when upgrading to Android 10. My tablet was working perfectly before the update but now will not auto connect. I agree this must be a software issue.
I have just upgraded my tablet to Android 10 and the Wi-Fi speed maxes out at 60 Mbit/s. I'm thinking about selling my device again, this is unusable.

All I can suggest is to create a bug report in Samsung members app. I did so over 10 days ago now and am awaiting a response. The more people that do so the better - a fix needs to be rolled out for this. Something's quite wrong with how the WiFi module is working after this update, probably driver related.
Has anybody tried wiping the cache partition in Recovery Mode? If that doesn't help back up your device and perform a Hard Factory Reset. That normally fixes any software issues.

With both the tab s5e's I've had I had reset them both twice, and cleared cache in recovery.
This is definitely an issue brought about with the update considering Android 9 was absolutely fine network wise.

In that case you may have purchased a unit from a bad batch.

I disagree, this is definitely a new problem that was introduced with the recent Android 10 upgrade. Samsung made the Wi-Fi signal "more stable" by limiting the modulation type to QPSK (MCS-2) instead of 256-QAM (MCS-9) which effectively caps it to 87,8 Mbit/s on a 80 MHz channel. Instead of 180 Mbit/s with Android 9 (which was pretty bad), users are now getting around 50 Mbit/s (which is incredibly bad).

My S5e won't auto-reconnect following the recent upgrade to Android 10. Also stutters and freezes for a while after restarting in various apps and settings. System software issues presumably.

Thanks for doing the research to find this out. This definitely explains exactly what I'm seeing.
Very disappointing as I was achieving fine speeds 290mbps or slightly higher prior to the update. Now WiFi on the whole is pretty poor in comparison.
Why was this done intentionally - it really makes no sense. Surely this must get reverted.
I just got an update this morning aimed at WiFi improvements

I can confirm this update has fixed all issues for me. Normal 433 link speed when next to the router and the same WiFi download speed as on Android 9.
Since updating to Android 10, I started having issues with mesh wifi (I'm using Google Wifi). Same position and setup that used to work perfectly with Android 9, now the table starts disconnecting from Wifi and I have to reboot to reconnect. Anyone else has this issue?
I'm contemplating buying an S5e tablet (in Australia). Does the reduced speed of WiFi impact on any practical applications ? My internet cable subscription is for 50mbps. It used to be 100mbps, but I dowgraded on purpose, seeing no benefit for the cost. Even at 50mbps (practically 46) we have moments like today when both myself and my son are working remotely to different employers, while my wife us watching a video. I realise there could be apps which require more bandwidth, so I'm just curious what those might be.

That is exactly my problem as well. Google WiFi and random disconnects from the tablet that sometimes get fixed by disconnecting/reconnecting but majority of the time a restart is the way to solve it.
No other device in the household gets disconnected from the network (neither was the tablet before upgrading) so it is definitely the update to blame.
Having similar issues following the update. I tend to turn the tablet off when I'm not using it, and thus far I have yet to successfully connect to WiFi on startup. I have to manually toggle WiFi to get it back on.
Same wifi issue here after updating to Android 10. Is there a way to manually update using file some were receiving in late July?
I am really bothered by this GROSS limitation too! It makes issues with the driver even worse.
Maybe our answer can be found on this page or something or nothing ?
