Still having very bad wifi issues.

Okay I posted a while back about this. For the past 2 weeks my wifi will connect and about 5 mins later won't load anything, but says I'm still connected. I've unplugged my router ( At&T router) and plugged it back in, no difference. I had att replace the router today and still having the same problem. I have it on wpa. I need to fix this, I run everything through my phone and this is really affecting my day to day. Any advice?
Infuse running infused v2.0.2.

If you're still using the stock ROM like I am, I'm finding the WiFi reception on my Infuse to be the worst I've ever experienced on any phone I've ever had. Lets hope the Gingerbread update fixes it.

Download wifi analyzer from the market and look see if there are several wifi networks on the same channel as your wifi. If so, change the channel on your router and see if that helps.
Also, what's the model on your router?

Even I've faced this issue ever since I got the phone but still there's no fix.
The problem is with a particular make of the router. I read online about it and there are more than 2 problems here.
1. If the router is a multiprotocol - bgn router, it might be a problem if the router is running in mixed mode. Our phone supports only b and g. In any case, if u enter the MAC address of ur phone into ur router, it might solve the problem.
2. If the router is not broadcasting the SSID i.e in hidden SSID mode, there might be wifi issues. Change the settings to remove the hidden SSID.
3. There is a PSP mode (Power save polling) mode in the hardware which will put the wifi to sleep if the phone goes to sleep (It is different than the wifi sleep policy) If the phone goes to this mode, some routers wont be able to send packets to the phone and this causes wifi to get disconnected.
If you try to connect to a public wifi, u should be able to connect. I guess the problem is only in ur home. I have the same problem but sadly i cant change any router settings since I stay in a university dorm...
Hope this helps!

Wanted to say I have a Verizon Actionteck router with FIOS and I am having the same issue with my Samsung Infuse 4G, only I am not using WPA I am using WPA2. I have to restart my device and then the device will work. Currently with WPA2 and I hide the SID and have the setting "Connect even when not broadcasting" enabled.
Thoughts ? I still have the 2.2 OS yes rooted.

[Q] Wifi without simcard

I would like to know if there is any way I can have my WiFi internet on my MT4GS,without my Sim card in the phone .Probably just surfing the net or using "whats app". I have tried and my cell doesn't connect to the WiFi router at all.Can someone advise on settling this matter ? My phone is unlocked and rooted.I haven't taken the update,so I'm still on the stock ROM.
I used my old windows touch pro 1 cell and it connects to the WiFi router without Sim card.So what can I do to get the WiFi internet on my MT4GS?

You should just have it.
I have two of these devices - one on T-Mobile, the other bought aftermarket out of plan. No sim card, yet I connect to wifi everywhere, even use it as a wifi bridge to my router for a desktop in my home.
Just go into settings, wireless settings, then turn on wifi and tap 'wifi settings' underneath it. You should see your network in the list, just tap it and enter a password if necessary.
Done.
This doesn't work for you?
Sim card has nothing to do with wifi, only cellular.

Maybe the fact that your phone is rooted. But I don't know my rooted cliq is rooted an connects to WiFi fine...

Could be, my buddy has a stock mytouch and he can't get on wifi without a sim either..

I don't think so - I just got it back from HTC and it's not rooted yet, still stock the same way I shipped it out to them. Gets on wifi fine with no sim card.
It does have an S-OFF bootloader, but I don't see how that would matter.
I do find this curious.
What exactly happens when you try to connect to a wifi network?
Does it even see the wifi networks?
Where does the ability to connect fail?

You should be able to connect. It'll have that option at the HTC setup wizard.

Says scanning ,then tries to acquire ip address then it disconnects and starts all over with the same result.Secondly I remembered the last two programs that were causing me problems in installing and uninstalling were Bloater and Busybox ,before my WiFi went haywire.I gave up trying and hence I was preparing to send my cell back to HTC, since it was still within the warranty period.I unrootted my cell and now my WiFi works again.So i really can't say exactly what caused this malfunction as yet .Thank you guys,for such quick responses.This really makes me feel proud to be part of an outstanding group of people here,and as whole, part of xda-developers.I thank you all for your help an assistance.Hopefully this information might help someone else someday.

Maybe it's your router

No my girlfriend,has the same phone with me and it connected .Had tried another router and it still didn't connect.

I do it all th time with several brands of phones. I have had problems the constanly connecting and reconnecting when there are too many devices around at the same time.
Sometimes it is the router and internet going through "spells".

Yes, "innerwebs" with wifi works without a sim card.
My g2 AND my other 4g slide both connect to my router without a sim in them.
But they are rooted with different roms so......

[Q] Wifi to LTE handoff problem (Rogers)

When I leave a wifi network (physically), instead of the phone recognizing that it's no longer got a wifi connection and flipping to LTE, it thinks it's still on a wifi network.
The only way for me to get my connection back is to temporarily toggle wifi off. Both Wifi and LTE seem to work fine otherwise.
Anyone else experience this?

Very common bug. Hoping an ota comes out soon.

Appologies, my searches didn't turn anything up somehow. Need to take Google 101 again, I suppose.
Good to know I'm not alone with this bug.

[Q] have to cycle wifi to reconnect

My wife and I both have S3's with Verizon.
Neither of use are rooted/unlocked/flashed. For some reason her phone has a lot of problems reconnecting to our home WiFi. After waking up, it'll see the SSID's of all the networks around us, but it won't attempt to do anything with them.
Only way to get it to reconnect is to cycle wifi or cycle airplane mode.
The wifi settings have been set to "Keep WiFi on during sleep" Only while plugged in on both phones.
I've got the routers set to empty channels (there are 2 routers, one is acting as a range extender, same SSID, different channel), and everything else has no problems.
My phone sometimes does this, say maybe once or twice a week, but hers does it constantly. More like a few times a day for hers.
What can I do?

Did you try and "forget" your network info and reinput the key to connect? Maybe try and remove the network saved info then readd it with a static ip and such since its most likely a dhcp issue on your network?

my wife and I also have GS3's and have the wifi set to turn off when the phone is sleeping. My phone when it wakes up sometimes will not connect to wifi. My phone sees the networks available but wont connect to them. I toggle the wifi off and then back on and then it works fine. It will do this sometimes a few times a day, sometimes it will be fine for a few days. It happens at work and home.

Are you on the latest OTA? I had this problem and it all of a sudden went away after I took an OTA update.

Yes I had wifi problems also...setting a static ip worked for me just set it to a higher number. For example I set mine to 192.168.1.199

Yes, I am on the latest OTA update.

Latest ota updates here also. I just set her phone to static now so ill post up in a few days with how it goes. I also disabled the extender a few days ago but it did not change anything.
I dont know if i explained the problem properly though.
The system doesnt attempt to do anything at all when this happens. It says there is nothing in range. As soon as you cycle the wifi it magically finds the network and connects without problems.

I had the same problem or something similar to yours. Whenever my S3 goes to sleep, meaning whenever I turn my screen off. If the phone sleeps more than 2 mins and I go to use my wifi. The phone shows I am connected to my wifi network but it takes 20-30secs for my phone to respond to my wifi and it will all of sudden my wifi is back on. I tried everything from rebooting my router. I haven't tried the static ip change but my wife's Rezound doesn't have that problem at all. It got so annoying that now I just leave it on 4G all the time at home. I do have the latest update from Verizon. Hopefully someone can figure it out.

The static IP arrangement worked for the wife's phone, and also turning the wifi to never sleep works for me too.
I really don't notice a difference in battery life between having wifi sleep with screen off and staying on all the time, so thats how I left it. Also stops the couple second lag between unlock and reconnecting.

I used to have this problem on my home wireless network. Never could figure it out, so I bought a new router (needed an upgrade anyway) and the problem went away. No idea why the phone had trouble staying connected with my older router (it was a Netgear model). Everything else connected with it fine, but my Galaxy always had problems.

Ya some routers can be a pain. I got a cheap $40 N router that cause more issues then not
Sent from my SCH-I535 using xda app-developers app

So, I tried to leave wifi on at all times per the suggestion in post #9. I did notice shorter battery life (not a huge difference). My wifi connect problems reduced, but did not go away. This happens everywhere: home, work, etc. Some times I will be fine for days, and some times it will act up twice in an hour. Don't know what router is used at work, but I know mine at home is a Belkin N router less than a year old. Never had problems with our old phones, and none of my friends at work or home have this problem.
Really wish there was a solution for this.

Specific wifi problem... can't connect to school wifi

My note is functioning normally! I dont have any problems with connecting to wifi at home, friends' places and even public wifi at like tim hortons etc.
BUT it doesn't connect well to the wifi at my university... and it definitely isn't the problem with the wifi signal or anything as my phone (galaxy note) connects fine as well as my laptop etc... I am not sure how to solve this problem... let alone figuring out what exactly is wrong...
In order to sign into the school's wifi, one will need to put it an id and password.. its a WPA wireless network.
To be more precise, my note sometimes will be connected to the school wifi fine without any disconnection but very frequently (at least 75% of the time I open up my tablet at school) it will not be able to connect or sometimes disconnect stochastically. I will have to try turning my wifi on and off a few times and if that doesn't solve the problem (which is the case for most of the time) I try restarting my tablet.... most of the time if my tablet decides it doesn't want to connect, nothing seems to work! I will just have to try and connect to the wifi some other time.
Any suggestions?
Thanks!

More info: usually the error is authentication error or wrong password or just doesn't connect.... all the info inputted is correct

Your school Wi-Fi just sucks, it's unstable. Or you have on your note an app that uses an restricted protocol. As an example, a router can be set to drop any yahoo related connection. But most likely just an incompatibility between your note and the router.

Could it be a region area cause wifi networks of that size have a lot of different routers all over the place working together and each router can be programed individually to do certain things like drop as the previous post said yahoo related protocol for example so does it work in some areas and not others

I'm having this exact same problem at my school. The wifi will intermittent reconnect, and sometimes won't automatically connect when I enter the building, regardless of the signal strength. It will say "authentication error" sometimes when it doesn't auto connect. Often it will also reprompt for the WPA key even though the saved one is correct.
Wifi works flawlessly at home, work, and friend's houses, but has issues with the school's.

Had similar issues at my school, its not your tablet its the wifi generally the signal strength is bad and that's y i struggles to connects but works sometimes, i realised it was router and signal when even iphones had problems

I made a topic about this a while back. The success of connecting seems to depend on the proximity to the wireless base station and amount of other wifi devices. Even in the worst environments, if I go into settings and disable/enable wifi multiple times it will eventually connect. I get the authentication error fairly often and just ignore it, disabling/enabling until it connects successfully.

I think Samsung WiFi drivers just suck happens to me all the time if there ever a login to connect

Ask the IT administrator if there are any limitations. Show him that you can't use the Wi-Fi with your device, maybe he will be able to help you.
