Weak Bluetooth and WiFi? - OnePlus 2 Q&A, Help & Troubleshooting

I received my OnePlus 2 this morning, bought it from China which has was a risk, however I assumed the LTE band would be the only problem.
Having set it all up I've noticed the strength of the wifi sucks, I can't connect to my router unless I'm in the same room.
Bluetooth is the same, it disconnects after less than two meters.
Is anyone else having these sort of problems?

nope

[Q] Bad WiFi connection. Any solution?

Hello everyone,
yesterday my new POV Mobii tegra arived. Everything works fine, except WiFi. Mostly i cannot connect to any WiFi network. If I get a connection, its very slow and often disconnects. I found other threads where people facing the same problem, but I didn't found a solution.
With my HTC Desire and other WiFi devices i do not have any range problems.
I tested different ROMs (corvus5, modaco r8, stock, buzz07 kernel) with various builds of the WiFi Driver (AR6k).
Has anyone a suggestion what I could do to get a better WiFi connection? Could this be a hardware defect?
Thank you!
Markus
I have this problem too. I have experimenting with different wireless routers. My operator provide me with a Thomson TG784 that has a weak signal. Now am using a Edimax BR-6504n. It is a bit better. But I am thinking of getting a Netgear WN2000RPT
Repeater. If anyone have a Netgear WN2000RPT please let me know if it is any good.
It would be interesting to know what people are using. So feel free to post the name of your wireless routers here!
If you have WiFi connection issues, it is worth checking that you have Bluetooth turned off. WiFi and Bluetooth seem to share the internal aerial and there are wquite a few posts about the two interfering with each other.
today i made more tests on signal quality. if my mobii says "50%", my router says 0% signal quality. if i'm on the same room as my router is, my mobii says 100% and my router says 13-18% signal quality. what the hell?!
I am having some connection issues aswell. It seems to drop connection but when I switch aeroplane mode off then on it seems to wake up the wireless and connect again. Really annoying, wondering if to return it back to the store.
Is there any fix? running 4.3 and no updates yet.
ps. my router is a Billion 7800n

[Q] Wireless signal strength issues anybody ?

Is anybody experiencing wireless signal strength issues with Nexus 10 ?
In the same room with the router the signal strength drops from excellent to none and back at will. Router is fine, I have other devices (apple and windows based) which have no such issue.
Yes I noticed the same issue.
No issues with my one, I have my router in the same room too and I'm getting full strength. Occasionally it drops by one bar momentarily.
Is it just the on screen meter showing the fluctuation or are you actually losing connectivity?

I notice that download speed drops significantly when that happens
Yeah for me too. When this issue appears I'm doing a speed test and the speed is slow as hell.

Hm, this is a concern. Is that new MIMO wifi thing too new to be released in a product? Hope not.
No issues for me, stable connection all around the house, even in the kitchen where my phone sometimes loses WiFi signal.
Thought I'd post a quick update. I set my IP to be static on Nexus and looks like signal got a bit stronger, it's Max or 3 bars without random dropping. Will see how it goes.

THis is a problem between Android and your router. Certain routers just have this issue, usually because they are not designed a specific way and do one thing or another out of official spec. This causes an Android device to drop out of connection every couple minutes or so. The biggest problem that causes this is routers that do not have a DHCP lease time set up. There are other causes too, but that was a major one. Also make sure you have wifi sleep mode set to never (I think it defaults to off when screen is off), and if you can also set your wifi mode to high performance (usually a kernel feature and I doubt we have it on this tablet yet)
Now this isnt talking about weak strength or losing bars. What I am describing is specifically for Android based devices that can have fine strength and then suddenly at any random time completely drop the connection to nothing, and then try to reconnect once more. Over and over

MIMO is OLD by now. Been around for years
I wanted to chime in here, because I was getting frustrated as well. I was having all sorts of trouble connecting to the 5Ghz signal from my Linksys e4200: sometimes it would show a connection but I wouldn't have internet access, other times the signal was super weak and unreliable. I went into my router's settings and changed the channel width to Auto (20Mhz or 40Mhz) and that resolved the problem immediately.
I hope this helps someone!
I am having a similar issue. Sitting about 10 feet from my router and my signal strength, bars, is down to 1. I know bars mean nothing but this is concerning.
Hopefully this is just a software issue. I have a spare wireless N router that I am going to hook up and use it just for the nexus to see if it helps.

Good question. I was actually thinking about creating a thread for this, but then I saw this! Anyway, I'm in my apartment where I usually get three out of four bars on my HTC one x, but on this tablet I'm getting between one and two, they switch from one to two nearly every ten seconds so maybe I'm right on the edge.
However, so far I have no complaints about Wi-Fi strength - I'm watching Netflix without any problems, browsing chrome is fast, and downloading apps has been fast. These are not very scientific tests, but in normal use it has been adequately speedy. Oh, except when I streamed the free HD video (I won't say which title in case anyone is trying to avoid " spoilers"), it switched from HD to standard definition a few times. could that have just been because lots of new N10 users were accessing it?

Not only do I not have signal issues, but the Nexus 10 is picking up about twice as many wifi networks as my Acer A500 or my DroidX, and no they aren't 5ghz, just better range.
Mine is. So far so good but I don't have a dual band router so I only have 2.4 GHz enabled' its definitely has better radio than my Acer iconia I tested both next to eachother. With Wi-Fi analyzer
I have the same problems... My WiFi signal is as good as it in my Hox, but sometimes my WiFi connexion drop and disappear, just to return after 1-2 seconds. Not sure if this could be a problem with my ****ty router but I have never experienced this "drops" with my phones or computers

You didn't have any issues with WiFi analyzer? Did you use it in the view that does signal strength of nearby networks as curves?

I've just done. I noticed that my WiFi signal had many "ups and downs", even using it in the same room where my router is. The signal wasn't very stable so I decided to use my phone as a router and connect the tablet. I have been browsing for a while with my phone WiFi network and I haven't suffer any drops. Signal has been stable so far and with the app WiFi analysed I get much better results.
So I think there is not any problem with the tablet. Somehow it is no it very "compatible" with my router. Not sure if the MIMO technology doesn't get along with my old router

I've tried something that seems to help, although it doesn't fix it completely. I accessed into my router's advance settings and changed the "signal interval" from 100 to 10 msec. Not sure this will apply to anyone, but it helped people with similar issues in their iPhone 5 WiFi signal. As I said, my signal seems more stable now

[Q] wifi best connection problem

When I'm at work and moving from one location to another, my S4 does not seem to automatically switch to the strongest wi-fi signal. It seems to "hold on" to whatever router it is connected to until it finally loses the signal completely. Only then will it re-connect to a stronger signal. I can manually work around this by turning the wifi off and on but this is a bit annoying... Does anyone else have this problem?
As an aside, I've not been able to disconnect during sleep by switching the sleep policy to "keep wifi on during sleep only when plugged in". Does this work for anyone?

As to your first point, that has been true of all my wifi devices (iPad, phones, laptops, etc.) I think that is by design because you might find your device constantly switching sources when competing wifi signals have similar strength or if the signals are varying in strength due to local conditions.

Hmm, thanks. I never noticed this issue with my old S2 strangely. Perhaps it's because the S2 lost a weak wifi signal whilst the S4 has a slightly stronger lock and hangs onto it for longer. It's just very frustrating because so often my phone seems to be hanging on to such a weak signal I can't get any data through even though a strong wifi signal is available and a quick switch on/off of the wifi solves it. Anyway, I can live with it.
Anyone have any insight into my second question?

Wifi issues on Airport Extreme 750AC

The only issue I've had with the phone since receiving it on Friday is network issues using wifi over and Airport Extreme 750AC, that we have at work.
I upgraded to the 6p from a 2014 Moto X, which had no issues at all with the wifi at work. Also no one else at the office has complained about this kind of issue either, with a mixture of Android and iOS devices.
The phone connects to the wifi quickly, with very strong signal strength. But something is interrupting the connection after 10-15seconds, causing full loss of transmission. After another 10-15 seconds of no connectivity, it will come back strong for another 10-15 seconds. At home, wifi signal strength and speed has never been better, using a Cisco e4200.
Has anyone else experienced this with their 6P?
EDIT - This still occurs if I tell Android to connect to 2.4ghz, or 5ghz only, and not automatic. Both 2.4 and 5ghz networks use the same SSID.
EDIT2 - Issue resolved. Was not due to anything on the device, but an issue with the network DHCP instead.
I've brought a Nexus 7 to work running Android 6.0 as well, and it has no issues with the wifi. Posting just in case someone else runs into the same issue.

Link found to WiFi 5GHz problems

So like everyone else I have the 5GHz wifi problem. If I'm not in the same room as the router you can forget using 5GHz. So I found the link to the problem. I just don't know how to solve it. I connected to the 5GHz in a trouble location while having mobile data and Bluetooth turned on. Internet speeds were terrible to the point the speed test would barely run. I turned Bluetooth off, and the speed test are right on par with my old phone, and 5GHz is working fine while Bluetooth is off.
5Ghz is not meant for long range though, 2.4Ghz takes care of that..
You should be able to obtain a signal within around 30feet, potentially more, but it'll drop off at that point.
2.4 carries a lot better..
Could it be to do with the channels that the phone may be using for WiFi??
Turn off all WiFi devices and Bluetooth in the room and see how the test goes.
Very strange.
I am a bit confused as to why people are reporting needing to turn BT off to operate 5GHZ Wifi. BT operates in the 2.4xx space. If you are saying turning it off resolves your problem this points to either a greater hardware/software issue or that you are not operating in 5Ghz at all.
I understand how 2.4 and 5 work as far as range and bandwidth goes. I tested this theory in the same spot my old phone would get 100mbps down (what I pay for) while connected to 5Ghz Wifi. The OnePlus 8 Pro while connected to 5Ghz in the same spot with Bluetooth enabled would cause the phones speed to drop to around 5mbps down and sometimes to the point I get nothing and losing connection. Now if I repeat the same scenario but this time I disable Bluetooth the connection is stable and speeds are 90-100mbps down. I repeated this multiple times sitting in the same location. Yes I understand that BT uses 2.4Ghz. I'm not saying that you need to turn BT off for 5Hhz Wifi to function. What I am saying is some how on this phone, and reported by others, the 5Ghz Wifi on this phone does not function properly. There have been zero solutions or reasons why that I am aware of. My post was pointing to a possible reason why and the fact that it is a hardware/software problem and maybe the right person could look into. I have no reason why the BT being on and off affects the 5Ghz Wifi on this phone and not the 2.4Ghz but it does. And my old phone was a $300 Samsung A50 that I was testing this phone against in my post. I tried to find what channels the phone uses for WiFi but was unsuccessful. If you find the channel lost I would be more than happy to switch channels and see.

It ends up it is an issue with the channel. Before I bought the phone I had manually set my router to channel 153 because auto kept putting me on the same channel as my neighbor. The OnePlus will connect to channels 149 and 153 but isn't really functional. I had to select one of the UNII-1 Channels. Once I did that 5Ghz worked and is functional and stable. The sad part is the reception isn't nearly as good as my $300 Samsung. Maybe they'll improve that if they can. I'm still bewildered why turning off Bluetooth allowed channel 153 to work.

Turn on auto channel on your router. You're going to have issues unless your entire network and devices are moderated perfectly.
Auto does the job
