Can anybody confirm, that wifi (wlan) roaming, between different access points on the same SSID network and different channels, is working?
I have at home 2 access point (one is on channel 1 and another is on channel 6) and my SGS2 wouldn't switch from one AP to another when I walk in the house. My son has SGS1 and wifi roaming works for him. Before I had Nokia N95 and I had no problems with wifi roaming. The same thing, when I'm at work. We have 3 AP's (all three Cisco) in the house and switching between them doesn't work. In order to switch between AP's I toggle WiFi off then back on again.
I went from KE2 to KE7, now I'm on Litening ROM 1.5, but it's all the same.
I tried everything, I can think off (set AP/router to b/g/n, only b, only g, only n, set different channels, set different security,...tried also flashing different modems on the phone...) but for me wifi roaming is not working...
Any ideas?
Anybody?
Nobody? Realy?
That's realy strange...
Nobody?
I really can't believe.... almost 90 views and no answer...
I'm I the only one with this problem?
While you are moving round your house do you lose connection, i think that your phone will be connected to the strongest signal.
mine loses signal when i leave home and auto picks up an usecured signal down the road.
I don't quite understand, what you mean...
When I walk in my house from basement to the top floor, my SGS2 is always connected to the router in the basement. When I come to the 2nd floor, where I have another Access point, it should switch to that AP, but it wouldn't. Instead, it's still connected to the router in the basement, which (in the Wifi Analyzer) shows -90 db (and the AP on the 2nd floor shows -30). When I switch off Wifi on my SGS2 and then back on, then it will connect to the AP in the 2nd floor. But then, when I walk back, down to the basement, it stays connected to the AP on the 2nd floor, even when I stand next to the router in the basement and Wifi Analyzer shows -28 db on the router.
I can confirm that wifi roaming is not working (at least for me). The phone stays connected to the same old AP all the time even with really poor signal quality.
Unless it loses the connection it doesn't connect to the best AP available.
Tried it on several ROMs (multiple stock roms and now I am on Cognition 1.20), same behaviour every time.
Exactly the same with my SGS2.
I also tried several ROM's, from original KE7 to latest KG3, now I'm on Lite'ning 3.2, and it doesn't work...
That's really strange...
Exact same issue here. Tried three different stock ROMs and a couple of modified ROMs and no change.
I'm even running Cyanogenmod now and the problem persists! How does that work? Does Cyanogen use the Samsung source-code for the Wifi driver?
It's really pissing me off. I basically cant use Wifi on the end of the house I use it most in without cycling the Wifi on/off switch as I pass a different AP on my way into the house to get there!
The most strangest thing is, that nothing can be found on the web about this issue (only one on code.google.com)...
And also here, on XDA, millions of posts, but nothing about wifi roaming...
Are people not using more then one AP/router?

Yes, I am sure most people use one AP/router - that is why you are not seeing too many responses. The source code is from the samsung source drop, the drivers were written by broadcom. We at teamhacksung have not modified them for CM7, so the behavior would be the same across all ROMs that are using the drivers unmodified.
So, that means, we are stuck with this, until Samsung fix it?
I still can't believe, that the best phone on the world (at the moment... ) has such a flaw...
What about trying driver for Wifi from SGS1? On SGS1 wifi roaming works beautiful (my son has one and he is laughing at me all the time ).
Is there much difference between SGS1 and SGS2 in the wifi handling?
Wow - this is an annoying issue to have. Yup, i have 2 routers too, and it really sux to be in an 'overlapping' zone and see the SGS2 connect to the router that is further away.
Is there nothing that can be done about this?

I'm very pis..... angry, when I'm in my room/office, and see, that my phone is connected to the AP, which is in my son's room, two floors above me... and I'm sitting 1m away from router...
Yesterday I tried in my office with 3 AP's with my friend's SGS2 with original stock ROM KE2 (he didn't change nothing on the phone).
Result:....... the same as with my SGS2.... wifi roaming not working....
Any news about wifi roaming?
How annoying!
I'm having similar problems at work.
At home connectivity's fine with just 1 AP. Here at work there are about 10 Cisco APs. Every now and then I have to turn WiFi off and on again and I use the original stock rom.
I have exactly the same problem, it always connects to the same AP, not the one with the better signal... very annoying! How difficult is it to fix that?

Which channel does this AP have?
Is there a method or an app that can automatically handle wifi switching between access points based on signal stregth.. like how an iOS device natively jumps to another AP if the signal strength is pretty low on the currently connected one.

I would love this to happen, I have 2 APs in my house & both my Galaxy S2 & EeePad refuse to pick up the best AP when I move about often resulting in my losing the signal.
Surely this is pretty straight forward & would benefit most Android users ?
Anyway, if anyone has an answer or can develop a simple solution I would be interested.
I'm having the same issue. I have 3 floors at my house, with cement between each floor so the wifi signal degrades quite a bit between floors. I have now setup 3 APs at my house (one for each floor) and I have to turn my wifi off and then back on the Galaxy S2 to get it to connect to the strongest AP - really annoying that Android doesn't do wireless AP switching...
Anyone have a solution for this yet?
I have one wireless router in my office (Linksys WRT54G) and another wireless router in my living room on the other side of the house (Linksys E1000)
Both are flashed with DD-WRT firmware. I have them setup to allow free roaming across/between the two.
Just about every wireless device I have will roam freely between the two routers except my Transformer Prime. I can be connected to the office wireless and have a great signal, walk to the other side of the house where the office signal drops off and pick up a much stronger signal off of the living room wireless but it will not drop the office connection and switch to the stronger signal in the living room.
I know the setup is correct because my Nexus S, Evo, wifes Evo Shift and iPad2 all will roam freely. Is there anyway to force the Prime to drop the weaker signal and switch to the stronger one? Thanks!
in ICS on my phone, there is a wifi option to avoid networks with weak signals. Presumably this is done by MAC and not SSID...but it's moot as ICS on the prime does not seem to have this option.
I had a similar setup, though most of the devices in my house are stationary, so i ended up reconfiguring to an Upstairs/downstairs SSID until i can invest in a more powerful router.
edit: like one of these! http://www.engadget.com/2012/01/09/amped-wireless-2012-lineup/

Hopefully this will get sorted with some new wifi drivers, or maybe after some devs start cooking up custom roms..

Did you ever get a solution to your roaming issue? I'm having the same troubles with my TF201. It refuses to switch to the higher signal access point even if I'm standing right beside it. The only way to switch is turning WIFI radio signal off the first access point when I go to the other side of the house. My Apply iPod seems to make the switch automatically.
Cheers.
P.S. I found a thread that discusses this issue at length and an app that appears to correct the issue
1) Thread: https://code.google.com/p/android/issues/detail?id=12649
2) App: http://android.googlecode.com/issues/attachment?aid=126490082000&name=MKermaniWiFiScanner-2.apk&token=Zwkr6Bx0HBP1XV4ZYFKiTAapeX8%3A1340206114901
I updated my post above with link to a thread that discusses the issue at length. It appears to be Android OS in general; specifically, ASUS and Samsung products.
I installed MKermaniWiFiScanner-2.apk posted above and it seems to work fine. The only complaint I submit to the developer was to remove the notifications every time the wifi scans for a different signal.
I called ASUS to inform them of the problem.
Anyone else having the same issue?
In my house there is a wifi modem and a wifi repeater, both have the same SSiD and all my devices automatically switch the one with best signal.
My android phones (LG G2, Galaxy S I) do not: even if the signal bars report high signal, I think they are connectet to the router with worst signal because I can't browse anything
So I am on t-mobile, and I also have one of the routers provided to me by t-mobile (I believe it's an Asus) , and I have noticed recently that my wifi calling has been sucking big time. It cuts in and out and says I need to connect to a wifi network, when I am connected. It's like it doesn't notice that there is a wifi connection. Anyone have suggestions as to what might help?
What is your isp bandwidth (down/up)?

100 down 20 up
WiFi calling on Android is hit and miss. I wish it was as stable as Blackberry UMA calling.
I tried the old turn it on and off again on the modem and router and it seems to have helped quite a bit.
Unfortunately, I have this issue for a quite while. Funny thing wifi calling works smoothly on pixel or essential phone!
How old is the router?
The router's WiFi radio maybe showing its age by being intermittent with its throughput's strength and/or signal's strength.
Try with newer router or access point. If there is a coffee shop with very good throughput strength (this is most important) you can do a test with that hotspot.
