Wifi roaming question/problem

My wife and I both have galaxy s2's and I've set the house up with 3 wireless routers... The problem is when roaming throughout the house the phones don't want to make the jump from one router (same ssid's/settings/passwords/different channels) to another. If I turned Wifi on and I'm on the middle floor I have max signal strength... If I move upstairs and stand next to the other router my signal on the upper info bar is at its lowest.... If I look at available networks though it shows my strength at max. It's only when I shut the Wifi off for a few seconds then back on that it Connects to the strongest channel but the process will repeat again when I go downstairs. What can I do to get our phones to switch to the strongest channel automatically? This is really annoying...

Here you can see what i mean... The strength is excellent when I view the network but it's still connected to the channel for the router downstairs even when a stronger "excellent" channel is 6 inches away.

Turn Wifi off for 10 seconds then back on and it looks like this...

you could try using those routers as repeaters, assuming that many people wont use the wifi. Wait, how big is your house? And do you really need three?

my house is about 2000 square feet but I live in japan where typhoon proof houses have 18inch thick rebar and concrete walls and floors...I have 3 routers, one on each floor wired with cat6 through conduits in the walls. Each router is on a separate channel (1,6,11) and they all work flawlessly as long as I shut the wifi off for several seconds. I just think its strange that the pic in post two shows that the closer router can be seen but its choosing not to switch in favor of the one that it originally connected to even though there is next to no signal.

You're not alone - Galaxy S2 wifi roaming isn't working
Wifi roaming isn't working on my S2 running 2.3.4 (stock Samsung firmware).
Looks like it's the same for others. Google:
"Issue 12649: WIFI roaming not working."
"you tube Hh2XXi4LQ1c"
(I'm not allowed to post links yet )
Waiting for ICS I guess.

It would be nice for galaxy s plus to get working wifi roaming.

I have the same issue on a Samsung Infuse running GB 2.3.6. Only way roaming works for me is brute force - either manually disable/reenable WiFi, or get far enough away from connected WAP that the connection drops. After either, a scan typically picks up the closest router.
I work in a building with a dozen or so APs, so a working roaming config would be very helpful.

Roaming roaming roaming
I use 2 APs that act as Bridge repeaters for my Sky broadband.
I cannot roam between them.
If I disable and enable wireless, the preferred access point is the last one connected, not the strongest signal. The only time I automatically get transferred to another AP is if the original is out of range.
Has anyone tried roaming with the new ICS official ROMs? Does this work?
Will upgrading my Modem to the latest version for Galaxy S2 (GT-I9100) help this?
Any answers to these questions would help greatly.

I just got the OTA update to ICS (4.0.3) in New Zealand. Unfortunately WiFi roaming has not been fixed.
Come on Samsung, sort it out! I was thinking of buying a S3, now I might go for an HTC instead.

Tunein alaways disconnecting

Hi,
I have my N4 since last week.
My tunein Pro have a inconsistent data throuput (spike of download) and have many disconnection problem.
I did test the same setup at the same time with a Galaxy S3 without problem and my Gnex is working well!!
Anyone have the same problem
I did try the factory reset without success.
Thanks

I did try it without success.
I even reset to factory default and only tunein running.
I will check the guy's at work as far I work for the carrier.
Here respectively on wifi and on 3G data usage.
As you can see on 3G there's spike in the data usage.
And on tunein on my laptop and tethering I have no problem

I'm with Videotron in Quebec.
Something intersting is that it's working great with station smooth jazz Tampa Bay station (128k MP3)
The problem is with NRJ 94,3 station (48k MP3) and CBC one radio Montreal (48k MP3)
With these station I have a incontinuous stream input with spike with interruption.
With smooth jazz Tampa bay the stream input is really continuous without any interruption.

Xperia SP faulty wifi indicator + wrong wifi indication

Hi all,
This morning I was investigating the common wifi issue on our phones. We all know some devices have this issue.
I did a small research with the app Wifi Analyzer and I found this small "bug"..
In systemUI (statusbar) you have the indictors for wifi, nfc, bluetooth, mobile network, time.
When you connect to wifi you get an ammount of bars. I discoverd the following:
(please focus on the statusbar)
Both phones use 4 bars (dot included) to indicate the wificonnection
First picture is from my Samsung Galaxy S Plus Running latest Stock Gingerbread 2.3.6

The second picture is from Xperia SP running latest stock 12.0.A.2.254 (non rooted)
BOTH PHONES WERE ON THE TABLE APROX 2 METER FROM OUR WIRELESS ROUTER!
For some unknow reason the indictator tells a diffrent story than the app Wifi Analyzer..
To be honest i think we all get fooled here. Both phones are having (in my case) a decent but not perfect connection and my Sony still thinks it is a crappy one. ( The option avoid bad connections is off in my case)
So perhaps this is also a bug in Sony roms?
Regards

From what I've read in the past, there is no industry standard to what "one bar" actually means.
That is for the phone network signal though.
I assume there is no standard for Wi-Fi bars either

Which is my conclusion here. When you see only the dot in your status bar. It does not mean it is a crappy connection

It shows that xperia sp wifi cannot catch the signals properly... maybe

Wi-Fi Failed to connect to network. Cant fix

Hello, i have a samsung GS4 Active Intl version that is a few weeks old.
When i first bought it it was working fine but after a week or two it started to show a 'failed to connect to network' everytime i used WiFi. I know its not a router problem cause it happens with every network i try to use.
my wifi may work for a minute the first time I use it but then this happens again, and again and again.
If i turn the wifi off and on it will work for 30 secs max. But then this problem happens again. Forgetting the network wont fix it, Rebooting the phone makes it work for a while but it then stops working again.
I tried a couple apps like FXR and wifi fix but they were useless.
Couldn't find a solution and im really desperate. I dont want to restore my phone.
Any ideas or suggestions are appreciated.
Thank you.

Wifi Problem
There might be a problem with your Access Point. I know on my access point I had the WPA2 Pre-Enterprise Authentication active. The wifi on my Droid 3 was in and out constantly. I disable the enterprise authentication, worked a lot better for me

Thanks but how do i do that?

Does this network use MAC-adress verification or is it connected to a wifi amplifier?

Is it on 5ghz? If so a lot of users are having issues connecting to 5ghz access points...

Are you using the stock ROM or a custom ROM?, and what version (of either)
It sounds like theres either a currupt kernel module (driver) on whatever version of android your s4 is running.. It could also be buggy power managment (wifi lock/sleep) did you try a factory reset?

i think you should see service center

try connecting your phone to a portable hotspot, if it works fine then there is no problem with the hardware and kernel, the problem might be the frequency of 5GHz, if it also gets the same problem then there is a bad news for you, yiu have to reset your phone or even in worst case you may hav have to visit srevice center as it could b a hardware problem

I solved it. I booted in safe mode and found out it was a third party app.
I just checked my apps permissions and reinstalled the ones with network access.
Finally found out it was Juice Defender. Thank Y'all for your help!

Poor WiFi Signal

Hello XDA;
A great deal of our PX xx chinese headunits have a very poor wifi reception due a tiny and small wifi antenna on these units. [example # 20]

}
What are our options to get a better wifi signal ?
Replace the stock antenna with a better one ? [ requires fiddling inside the unit itself ]
Extend the stock antenna with a copper wire to the radio / nav / gps antenna ?
All these units have USB ports, so i thought - plug in a wifi dongle and hope for the
best but it seems my PX6 unit cannot detect any of my 3 dongles i have tried so far.
So ... are there any options left ?

Not MTCB, requested mod moves post to (Android head-units) forum
Also, OP, being senior member should know better than this. Read the /&$₩÷(÷¥ forums which cover this very issue.

@P2.nl Is your WiFi reception bad? What are your WiFi speeds? 2.4 or 5GHz band?
I believe the antennas that come with these units are meant for close distance so that they can use a phones WiFi hotspot.
Yours looks much larger than the "antenna" on mine. Mine is only two small wires that are maybe 1 cm in length. I can access my home router from my garage and also connect to my phone while in the car for internet access. When attached to my home router, the speeds are slow, though.

When i use my phone hotspot option [2.4 Ghz] in close range, then i have a decent connection.
If i park my car straight under my appartment it can pick up my home's wifi network on a weak
level, in distance +/- 10 meters, when i park my car 5 meters further away then no wifi signal.
I do not have a unlimited data plan on my cell phone so prefer to update all my devices thru my
home network, i tried 3 different wifi [atheros/realtek/ralink/2.4/5.0] dongles to see if my android
px6 head unit would detect them as a plug & play device but that was not the case unfortunatly.

All units from all competitors with bluetooth and WiFi 2.4GHz do have this issue. The newer versions of Bluetooth and 2.4GHz are using the same frequenties and thereby disturbing each other, especially if it is a shared chip. That is one reason.
The second reason is metal around the antenna.
A special antenna can help but it is better to place it outside the metal cage of your car.
Wifi is subsceptible to surrounding metal. After all we are talking about electromagnetic radiation which is also absorbed by other metals than only the copper wire in your antenna. If you have an extra antenna with a longer wire then place it under the plastic of your dashboard (or on top of your dashboard). Most dashboards have rigid metal constructions underneath.
Another dongle is not supported as they removed that from the usb-wifi drivers.
Note also that "tiny and small antenna" is not really correct. Length is based on frequency. (and how small do you think a phone antenna is).
Only the latest units featuring 5GHz WiFi work nicely as they again function on a different frequency.

I had the same issue before I changed my cell plan to have unlimited data. I'm in Canada and there are very few carriers to choose from. There is only one reasonably priced carrier with "unlimited" data. They reduce speeds after you have reached your monthly allocation. The allocation is good but I like that there are no overage charges.
Back to your issue. Several things comes to mind:
You can try a WiFi extender for your home. It might give you more signal where you need it. However, it may not. Only way to know is to try it. If your router is not immediately above your car, this may work by placing the extender immediately above your car.
Your router may have options to increase the signal strength. Not all routers have this option.
You can update your apps where there is free WiFi available. Where I am, there are a few retailers that offer this. Parking outside while you go in for a coffee and maybe a donut.
One thing I did was to turn off Google Play Store automatic updates. If everything is working, updating is not required. This can save a lot of data as each update seems to take several hundred megabytes or more. Only update occasionally or when needed.
Another thing I noticed was that the Google Play Store kept updating apps even if they were recently updated. This happens even on my phones as well. I remember looking this up and found many people reporting this issue. One way to verify this is to check the date of the updates that are presented. You'll find that some of the presented updates are not recent or may be the exact same as the apps that you have currently installed. This is another reason to turn off automatic updates.
