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?
I had an issue with my s2. i was stuck at Menorca airport after an 8 hour delay. i spent the firs 30mins walking around the lobby looking for wifi and got nothing.
couple hours later sat next to someone with an iphone 3g and he mentioned he was glad of the free public wifi - free public wtf I said!
Sure as it was, he could find and connect to a lounge wifi. My s2 couldn't find a dam thing!!!
I checked my settings:
Wifi was on
Network notification was on
Use packet data was on
Data Roaming was off - As I don't want O2 to screw me over.
Could it simply be that the wifi signal wasn't strong enough to get the wifi? Eventhough the Iphone 3G had three bars where I was sat?
Could data roaming someone interfere with connecting to wifi abroad?
KH3 modem improved WiFi signal i find .

I'm on KF3...
Can I install one of the other variants of stock rom such as KH3?
If so I assume I need to CF-Root then overwrite with the variant stock rom/kernel I want?
And then CF-Root again the new variant stock rom/kernel?
Yes, the SGS2 has not-so-good wifi signal. Sometimes I can't get a full signal when I'm 2m away from the router. Nevertheless, I've found places where my phone was connected, and other devices couldn't, so it's not that bad. I'm also on KH3 modem.

Ok so I've had the Galaxy s2 for a month now and everything's been just peachy up until 3 days ago when i noticed the wifi doesn't work as it should.
The Problem: my wifi connects and shows a strong signal but there is no data coming through. all my other devices on the same wifi network are A-OK its just my phone that gives me the finger. When i switch wifi off and kill all background tasks then reconnect it works again for like a minute if i'm lucky. 3g works fine.
I'm running the gingerbread 2.3.3 XWKE7 that i bought the phone with. is this a known problem? if so how do i fix it without going through my useless service provider (Vodacom - another way of saying "Pig S#!t!")
Please help. Thanks.
Check for firmware update first as that is very old KE7.

It happened to me once but when I restarted, things became alright.
Thanks
I tried turning it off and on again, took the battery out too and still no joy.
I reckon firmware is the way to go, theres no updates on kies yet though so i'm thinking of flashing to lite'ning ROM. And its definately not hardware cos i've been wifi tethering from the phone for a while now with no issues. I'll try a factory reset first though and post what happens.
Ok so here's my findings: I Flashed to Litening ROM v6, the phone is a lot quicker but, wifi is still stuffed for some reason. I can wifi tether and it works perfectly but I still can't make use of a wifi network, it still connects but doesn't get any through-put. and as before 3G is working fine.
Any other suggestions?
Thanks
I think it's somewhere in the router settings, but my wrt54g at home with dd-wrt can connect just fine with my Epic 4G Touch running Cyanogen 9 (or any other ICS rom for that matter). The one we have at work (also wrt54g running dd-wrt) won't. I'll reference this thread here: http://www.dd-wrt.com/phpBB2/viewtopic.php?p=667631
I've changed the "no acknowledgement" setting, changed security modes, disabled the SPI firewall, and even tried factory defaults. But it just doesn't want to connect for some reason, however when I use a gingerbread rom it will connect just fine.
So my question is, if anyone has found a solution as to why ICS phones don't like connecting to DD-WRT routers.
Widespread issue
I don't know if it's any consulation but this issue seems to be affecting a lot of people. << link to thread on sprint's site but I'm new to this forum so can't post it >>. No one on that site mentions dd-wrt but that doesn't mean it isn't a dd-wrt specific issue.
I am also expericing what I think is the same problem. I am using the Sprint Nexus S 4G connecting to my linksys wrt320n router with dd-wrt build 18946M (I upgraded from 14700(ish) to see if that resolved my issue but it didn't).
The issue seems slightly more complicated than a simple inability to connect. Before upgrading to ICS (in stock ginger bread), a few days ago, I would occasionally see my phone attempting to connect to my router and failing. Now with ICS, my device connects, gets an IP address and the router wifi status page shows the device as connected with good signal strength, but alas, there seems to be no network connectivity.
I decided to try CryogenMod 9 and see if the issue was resolved in their build. So I flashed the lastet (update-cm-9-20120411-NIGHTLY-crespo4g-signed.zip) cm9 mod and still experience the same issue.
Any help anyone could provide on this issue would be swell.
Confirmed it is DD-WRT
I came across this thread immediately after upgrading my router from stock to DD-WRT. Immediately the wifi on my phone stopped working. My phone, Nexus S 4g will not even see the network. Conveniently my neighbor has the same router as I do, a Cisco e3000 with a factory rom. I can connect to his network without any problem. Ugh. I love DD-WRT. Maybe I'll try a Tomato firmware... Well at least all my other phones/tablets work. It is specific to the Nexus S 4g.
UPDATE: I believe it is tied to the mixed network mode on my 802.11n router. I tried my old 54G in G only mode and it is working fine with my phone

Confirmed. I changed the wireless mode to 2.4Ghz N only and everything works. Mixed Network mode was giving the Nexus S fits.
I just *successfully* got my MotoE/Android5.1 working on DD-WRT after 2 days down (problem started w/new version of DD-WRT on a repeater)
MY WORKING SOLUTION: Turned of "auto" on the channel selection of my 2.4Ghz channel on both primary and repeater routers, turned control channel to 20 on the primary (where the DDWRT offerred a choice) then restarted phone. It was probably something with auto channel on one or both of disparate routers.
Phew. Nasty glitch.
I used to be able to connect to my 5ghz wifi network without a problem. It stopped working recently when I flashed one of the CM9 ROMs. I thought it had something to do with the ROM but it was working on earlier CM9 builds. I flashed back to Task650's v14.1 ROM where it used to work fine but I still can't connect. It sees the network but when I click connect it doesn't do anything. I haven't made any changes on my router and I can connect to my 2.4ghz network fine. I have a Linksys E3200 router with the 5ghz network setup on channel 36, 40mhz channel width and WPA2 personal security. I've tried changing all the settings on the router but i still can't connect. I did Odin back to stock last week because I was getting a lot of reboots on the CM9 ROM I was running. After that I flashed CWM and then flashed the latest CM9 ROM. It seems like the trouble connecting to my 5ghz network started around that same time.
Does anyone have any idea what problem could be? I have a 7510 32gb Tab.
Thanks.
Does anyone have this issue? I Odin'd back to stock 3.1 and I still couldn't connect to my 5ghz network. When I click on the network it doesn't do anything. I found this issue with the galaxy nexus connecting to 5ghz wifi - http://code.google.com/p/android/issues/detail?id=22474. A lot of the posts on there describe the exact same problem I am having. I used to be able to connect fine then it stopped working. It was working fine on the stock ROM, all of Task650's ROMs and all the CM9 KAMGs. I was flashing a lot of the CM9 ROMs during the time it stopped working. It could be a hardware issue, but the fact that it sees the network fine makes me think it's not. I recently upgraded the firmware on my router and did a factory reset on it but that didn't help.
I have this same problem on my Galaxy Nexus. Put your phone really close to your router (a few inches) and I bet it will connect on the 5GHz band.
If it connects at really close range then you know the hardware is damaged... my guess is samsung has some kind of serious design flaw in their phones for this to be happening to so many people on different models of their phones.
5GHz bug?
I recently discovered that my Tab 10.1 works with low channels (eg 36) but not high channels (eg 149). I was surprised to find quite a number of postings about the same issue. Is there a firmware issue or is it a bad RF chip? It seems Samsung has a problem...
If anyone is still having this problem I found something that worked for me. The info below is copied from this issue http://code.google.com/p/android/issues/detail?id=40999#c4
"...only channels 36, 40, 44 and 48 work for 5GHz on the Galaxy Nexus. (My AP was on auto and blasting on # 149).
I manually set it to 48 and presto I was connected."
There's an error in the configuration file- /system/etc/wifi/nvram_net.txt
