Wifi problems

I'm on stock efo2 with ef10 modem
I can connect to 3g and 4g just fine but wifi disconnects as soon as it connects
Its not my router cause my iphone 3gs and nexus s can connect and I went to my friends place and tried his too.
My epic could connect before so I'm wondering what wrong
I don't think my modem failed

Changed channels on wifi router
Both my wife and I have Epics and they did the same thing a few weeks ago. Very frustrating when your 3g signal is weak at the house. My phone had been rooted in the past but I was back on stock for other reasons. My wifes phone has never been rooted. I decided to root my phone again and went to the EE03 modem and gingerbread rom to see if that would help. It didn't. I tried my old SDF rom from a few months ago and it was still the same. Finally I went in to our router settings (even though it works great with our wii, and both laptops) and changed the channel from 1 to 11 and now our phones connect great and stay connected. What really baffles me is that my phone wifi seemed to do the same cycling thing on other wifi signals as well. I haven't tried it at other places since it started working at home again. If I think of it I'll do that and post back the results.
So for me, changing the channel on our wifi router seemed to fix the problem.
Might be worth a shot.

Thx
Ill try that
Now time to google how to
Today after I left my house and left for work my modem just died so my phone was just as good as a brick
I just fixed it now
And as you said flashing modems dont help

damn changing the channel didn't work
I changed from 1 to 11
Still can't connect
Channel 8-11 are completely empty so wtf is wrong
I also just went over to my neighbors place and connected to his wifi just fine so I know my epic works

wow, im having the same problem too. I'm on EF02 modem with EC05 ROM (SRf 1.2)
I can't connect to my home wifi at all, but all of my electronics can....

Question... Do you have your settings for your Wifi router saved on your phone? ...My buddy was having this problem yesterday, and I told him to reset the settings and he reconnected and everything worked after that. It's worth a shot if you haven't tried it already.

Damn it didnt work

Try a different modem, like EF02, EE03, or EC05. Or something in your rom may have gotten corrupted. Try flashing a new rom and kernel. Wipe everything first. Or try a nandroid from before you had the issue, if you have one available. Not entirely sure these ideas will help, but worth a try I suppose.

Bump and I guess the only solution is to buy a new router

Fixed
What I did was go to cmd prompt
Type ipconfig
Take the number next to gateway
Paste that number into the browser
Google what your router's default password
Now find factory reset
That's all I had to do

how old is your house
I just recently moved & @ my old place I couldnt get my wifi to work @ all or even work on my xbox that was 5ft from the router & then i move out, dont change anything & like magic my wifi works perfectly on everything. i was told it was bc my old place was sooooo old it was made back when they used chicken wire to hold the "drywall mud" bc back then drywall didnt come in sheets it came in a bucket...

Not sure if this is the same problem or not.
My WIFI shows as being connected even when it is not connected. Thus, it appears that I am connected but data is in fact NOT working.
I tested this by choosing an encrypted wifi connection in my neighborhood and entering a random password. To my suprise IT CONNECTED! Nope, not really. it just showed like it was connected, it really showed that I had connected to my neighbors encrypted WIFI, but when I opened the browser to navigate I got nothing. Fooled me.
Any ideas?

SOLVED[Q]Wifi continuously scans even though connected

I am on Legendary 2.1 and just had it pointed out and I verified that even though my wifi is connected to my router it continuously scans every few seconds. This has got to be a battery drain. Is there a way to turn off the scanner when connected or set it for every 5 minutes instead? Thanks.
Edit: Thanks TeamERA for explaining that it only does that while in the listing window so it can update the list immediately. It defaults to the scan interval in build.prop when that window is closed. Thank you.

I think romtoolbox allows you to change that Im not sure but you can check it out.

Sorry root tools by jrummy allows you to change wifi scan intervals

I'm pretty sure you should be able to turn off 'network notification' while connected...this should stop scans since this option is made to notify when a network is available. In theory, if its not notifying you if new networks are available, I would assume it's not scanning. Good luck

I found a program called wifi buddy on the Android market. This program allows you to disable wifi scanning.

I will try that...thank you! Probably add hours onto my battery life on weekends at home with wifi on.

Wifi buddy settings only control that app not the system settings so disabling wifi scanning only worked inside app not to system wifi scanning

I'm not knowledgable enough yet, but has anyone looked into using SQ Editor? Perhaps something can be manipulated in system files to just disable intermittent scanning all together? Only initial scan when wifi is activated? Just an idea...

That's what I was hoping for. Can't seem to get a DEVs attention to look into this. Build prop edit doesn't do anything.

Trying to find any sort of process or folders in root explorer that relate to wifi/scanning and coming up empty...I'm with you Kenny, we need a dev to pick this up, especially if editing build prop showed no results

I think my phone is doing this too.
In betterbatterystats mmc_delayed_work (under kernel wakelocks) accounts for 90% of my wakelocks, this does not happen on 3G so it is definitely related to Wifi.
I thought it had something to do with my router (DIR-655) as other people said they experienced unusual drain with that router.. Not so sure now.

This is probably the main reason people are complaining about their battery life on the gingerbread builds. I think it is more of a EI22 issue. How did EH17 or the previous gingerbread Roms handle this and if it handled this issue better can we take something from to fix our problem.

It would be nice to actually have the system manipulated, however, I am pretty sure that Juice Defender has an option of wifi control...I think (and I don't fully remember, just went to Thunderhawk and haven't put it back, trying to figure out other ways to better battery, as is everyone else) that you can allow JD to stop all wifi unless user selected.

So I don't claim to be a dev, but I just thought of something that might lead you in the right direction. I remember a post about lowering the signal threshold on your phone to get better 4g connectivity a couple of months ago in the general section. Its a dialer code and you need your msl to gain access. This is one of the phone settings like at the bios level. When I did this, I was able to see a boatload of settings that you would not find anywhere in the os settings. If you know where I am talking about and know the dial code to get in there, I do remember seeing some wifi stuff. Maybe something in there you can change scan or retry rates, with signal thresholds that might work for you. Write down all changes you make if u need to go back.
Again, just a thought trying to help.

CM7 issues. (Dolphin browser, 4G, in-call sound)

So I believe I've had this issue everytime I fashed any kind of CM7 to my phone. The backup of my dolphin browser never actually restores correctly. All my other apps restore their data perfecty and work fine. But dolphin browser always just restores the app but I can never get my data back on it, so I lose all my bookmarks and saved emails and stuff which is annoying and sometimes I forget some of my passwords lol. But has anyone else had this problem? Even when I backup my bookmarks from the app itself and restore them it never gets me them back.
And the problem I'm having with 4G is it never connects or shows up. I know I need to have 3G on first, and I do, but when I turn 4G on it says "turning on" then "unknown" and it never even shows in my status bar as scanning or anything.
Also, the in-call speaker sound stays on the loudest even when lowerng it to the end. Its like that with regular talking on the phone and head phones, and no, its not from voodoo control. But is there anyway to fix this?

Tb. I always use it and it works perfectly on every other ROM I flash. Its just cm7 I'm having problems with. And no the backup isn't corrupted or anything. I'm thinking maybe it could be because dolphin runs differently on cm7?? Or has some kind of different data?

I can't imagine that the data would be stored in a different location. But you even said dolphin's own back and restore doesn't work on cm7? I would say that is a dolphin issue not a cm7 issue contact their support.

Ya that's what I'm thinking. Maybe it runs in a different way or something.
But anyway, that's not the biggest problem I'm having. I don't mind that as much as any of the other two issues.
4G, for some reason, just isn't working for me. Can anyone confirm that it actually works so I can see where the problem is from?
Also, the in-call speaker sound stays on the loudest even when lowerng it to the end. Its like that with regular talking on the phone and head phones, and no, its not from voodoo control. But is there anyway to fix this?

Maybe, or maybe not. Ill restore my backup of thunderhawk and test 4G to see if its from the ROM or the network. And I seen another tread talking about the in call sound to always being too loud so I guess that's a ROM based bug but not a big problem.

No data connection after flashing a new ROM? Look here for fix.

I experienced the problem of no data connection after flashing a new rom on my Optimus G. The phone needs to be reprogrammed, updating your PRL and Profile will NOT help. You must dial ##72786# this will start the handsfree activation and your phone will reboot a few times. It may take a few seconds in between steps of the activation and it will seem like nothing is happening. Just be patient and wait for everything to complete. When it is finished your phone's data connection will be working properly.

Some history,
I've been running Imperium and stockishv1 and v2 for a few days. I've made a couple backups along the way. About an hour ago I lost data. The phone works and makes calls, but my data is dead.
I've tried update profile and prl, and all I get is" Network error" I've tried this many times throughout all these steps.
I've restored backups, pre-Imperium and Stockishv1 with the same results.
I tried the procedure in this thread and still nothing.
Anybody have any other ideas? Would LGNPST restore the phones modem?

I killed the connection optimizer while I was at work because I can't use work's wifi and listen to my icecast station I setup.
This killed my data connection and immediately put my phone into roaming. I rebooted like three times and finally my data came back (i also updated the PRL and the Profile, not sure which fixed it but something did)
From the things you guys speak of, I would guess the same issue is at hand.
ALSO: Stock rooted rom (non-deodex pure stock with bloatware frozen with titanium)

Try the G2 thread, I'm sure if you post in the exact same section over there you might have better results. General answer is that it is probably APN settings. Find an app, enter them, set it, and reboot (might not need to reboot).

[Q] Wifi connecting issue

Since last couple of months I'm facing this. My wifi, once connected, stays connected. But once turned off, after turning on, it would just show the connection as saved, secured with wpa2 and won't connect. Turning off and on multiple times doesn't help as well. Just if i keep it off for some hours or so, then turn it on, it might sometimes get connected. The signal strength is excellent though and once connected, it stays connected. I've tried factory resetting, formatting data as well. Tried a lot of different roms but in vain. Could this be a hardware issue? Is there any workaround for this?

Does this occur with all wifi locations?

I didn't think the radio would impact Wi-Fi.
I would try to see what happens on another Wi-Fi hotspot, to rule out something with the home wi-fi.
