[Q] Wifi connectivity issues - AT&T Samsung Galaxy S II SGH-I777

I got my GS2 not too long ago, and from the start, it's had issues connecting to my house router. I've tried the wifi elsewhere, and it works just fine.
I have about 7-8 other devices that connect to my router in my house, and they all work. Why doesn't my GS2 work? It's still on stock rom.
I have Verizon FIOS and the plain router they give you, if that matters. Looking for answers before the 30 day window if possible.

Have you tried restarting your router?

Or check for a firmware update for your router.

Is your router a D-Link? The SGS2 hates D-Link's. It has a fondness for Netgear's.

Will that really help? Everything else works fine.

I'll do it now since it sounds simple enough.

It's an Actiontec. Never heard of that brand.
Is there anything else I can do or check to figure out this problem?

Nvm. I restarted the modem, forgot the connection, then reconnected it. It worked, though it's kind of a weak signal. Thanks given to those who posted.

not the first time I've read that people were having weak wifi signals on their SGS2. I have yet to experience this myself so I'm guessing its incompatible with some routers. I have a verizon fios router and it works great.

I've noticed weaker signals on my S II compared to my captivate and my wife's Atrix. Nothing huge.
That's off a westell 327 dsl router.

I've had no problem connected to secured wifi, but whenever an open wifi is available and I get the notification, when I try to click on it, I just get a Settings crash / force close notification. If I try to manually go into settings and into wifi, it does the same thing. Phone is unrooted - anyone else having this issue?

wifi fix? not for me
I found somewhere online that you can punch *#*#526#*#* into your GSII, and it fixes wifi problems. When I do this, it does begin a driver download, but it never seems to finish. I'm still having the force close issue when trying to open settings to connect to some open wifi sources.

Wifi has this weird issue where it wants to scan my home network even though its connected a million times to it. Almost like it forgets lol. I usually have to disable then enable it; not a big deal i guess but still a bug for sure!

Mine does the same but after I wake the phone I have no problems. Maybe a 3 second delay reconnecting.

Release notes would be great. Photon WIFI/VPN is putting out extra packets which are then blocked by some routers. If the wireless router is used as a router and not an AP and IP6 is disabled, the problem seems to be corrected (i.e.: no reconnection failures in over a week when it used to happen every 2/3 days. See motorola photon forum for more details.)
My wifi seems to work pretty good at work and at home. I havent noticed the phone constantly scanning but I havent been looking for it either.
as of today my phone will not connect to wifi at all... release notes and date would be very much appreciated.

Any confirmation on this update? I have to reboot to use my GPS pretty much every time. SG2 comes out Friday, I'm returning it if I can't get a solution.

Me either always works and works great, also pretty fast as well. My issue is the voice/3G radio locking up and then the phone reboots.
so it seems some are having a WIFI issue and others voice/3G... rather odd thing going on there.

Might want to check and see if that said the 19th, pretty sure you guys don't have any MR's this week.

FoxFi won't accept connections.

When I first got my Evo LTE 3 weeks ago I popped on FoxFi and I could connect devices no problem. However, the data speed was soooo slow that I ended up uninstalling it soon after.
Now with the update to the Evo I thought I'd try again for kicks.
Now, I can't connect any computer/device to my FoxFi connection. They can see the Wifi hotspot but only tries a few seconds to connect and then errors out.
Major bummer.
Any tips/tricks for this?
Make sure that when you turn foxfi on your wifi cannot connect to a router. If your wifi connects to a router foxfi will not transmit the right way and you will get error. Just go to the wifi settings and click forget connection on the phone and then try it. I was having the same issue and that fix it.

Hey, thanks for the reply. I should have mentioned, I turn off wifi before doing anything with it, so that isn't it.
have you tried a reboot? my friend's sgs3 just had the same problem and a reboot got everything in working order.
When you turn foxfi on it will also turn your wifi on to work properly. Just make sure is not connecting to a wireless router and you should be good to go. Just try it.

I keep assuming that purple would assume I tried the basics.
I rebooted. No good. I tried uninstalling any recent apps just in case, restarted. No good. I tried it with and without encryption, renamed SSID, reinstalled the app, tried with Foxfire add-INS. No good. We tried the same stuff on my buddies phone too. Button.

I have wifi off while trying all this, no possible way to be connected to a wireless router.
Thanks guys
Even if you turn it of before starting foxfi foxfi will turn wifi on so it can transmit the data. Go to your wifi setting and click forget on the wireless connection that you currently use to connect thru wifi and then try foxfi. Foxfi will turn on also your wifi will turn on but because you took out the router out of your connections you will not connect thru the the router and fox fi will be working again. Same problem happen to me and it took me 2 days to figure it out.

That did the trick! Thanks buddy.
I wonder if anyone has submitted a bug report to FoxFi for this?
Does anyone feel the need to use the FoxFi Add-On package with the FoxFi app?

Dont buy me a beer just klick thanks.:cyclops:
Yes. I had no idea abt FoxFi bcuz I had rooted my fone but I uninstalled the root 2 do the OTA update then couldnt get the root back. So I looked on here in themes & apps & found out abt Foxfi. When I typed it n the FoxFi add on showed up n the playstore & tht gave me the link 2 go 2 the developers website 2 download the app bcuz Sprint & AT&T removed the app out of the playstore, so once I installed the FixFi app I also did the add on. In the menu settings of the FoxFi add on app it lets u hide ur mobile hotspot usage 4rm Sprint so they dont kno ur data usage on the hotspot. It works fine 4 me, I checked it 2 c if it notices it when I chk my data usage & the mobile hotspot data is 0....this is a gr8 app!!

Why is my works WiFi is fso slow when I have good signal?

It Works ok if im less than 5 meters away from server. But anything over that and its unusable. I work about 10 meters from the server. And I get at least 2 - 3 bars of signal out of 4. And I can't even post a comment on here. The speed is very fast for about 30 seconds and then ridiculously slow. It also struggles to connect. Tries about 3 or 4 times before it connects. I'm running cm10 on s3 but have this problem on stock, omega and checkrom. I had simular problems with the s2 aswell but not s1. I don't want to use wifi kill as its my work and it might not solve the problem. Is this the s3 working on networks with multiple apns? Is there a code I can call to turn off power saving ?? Can't force to 5ghz either.
Some advice would be massively helpful. I am getting very frustrated.
Thanks in advanced

I believe the problem lies in network or in the wifi router. Maybe it's overloaded, try on-off cycling the router and see if it works then?
I kinda doubt that the issue is in the phone
I've fixed it now mate. Well chuffed. Don't know what it was really. But the method I used in above thread worked. It all started when I first rooted and flashed omega. Cm9 got rid of the authentication error (so it seems Sammy is at fault there) as for the WiFi range of about 3 meters and no connectivity after that distance. I'm not sure. Perhaps a problem deep in the settings I could not find. But completely wiping all settings worked. Not ideal. But confirmed working all day at work. So maybe a omega fault I don't know. Jus happy to have fixed it

It can be many problems! Maybe the ROM that you are runing has poor Wi-Fi support or maybe the phone is just "getting old" or maybe its the Wi-Fi set that sends you the signal!
I got a s3 which is not old but I've fixed it now. Thanks

As above.....also router security settings might be causing a problem, I had that, in fact most Wi-Fi problems with the S3 seem to be router side from my observations, but that is just my humble opinion
On my old HTC HD2 after a Rom upgrade it wouldn't detect WiFi networks on channel 13. Our router was just on that channel. In the phone's WiFi settings go to Advanced and you should see something like channel range. Best of luck

[Q] Wifi is terrible on b/g/n but okay on a

So, last week my Note started dropping wifi on my home 802.11g wifi. It was really bad, constant dropping, and when I was connected browsing was futile. The note said it had high signal strength, though.
I opened it up, and disconnected and re-connected the long antenna on the power button side. Didn't help.
I replaced that antenna and the rear cover with a "new" one off ebay. Didn't help.
I did find that I can connect to the work Wifi on 802.11a fairly well. 12-18 Mbs connection.
I also connect to the home wifi just fine if I'm within 2 feet of the AP. So, I presume that the note just can't transmit very well.
What should I do? is there another board or antenna that I should replace? Should I get a new motherboard? if so, where can I find one?
No one, eh?

It works at my work. But only on 802.11a
I bought a dual band wireless router so I can run 802.11a at home, so now my frustration is only limited to stores and places that on run 802.11b/g
I still want to fix this. I may have to sell the phone and buy a new one.
Interesting... You didn't say whether you've tried a factory reset yet... But I would definitely try that. Also would try using Odin and going back to stock. Does it make a different whether Bluetooth is disabled (b/n and BT are very close in wireless spectrum)?
