Wifi Strange Problem

Hi!
I have a problem with my p3600. It is wifi related.
There are some wifi's that, when i connect i can navegate for a little time, then it suddenly stops working (says connecting....) and then wifi won't work again until i reset the device (stop/start wlan doesn't work, it doesn't find the AP's again, no networks found).
When i soft reset, everything works again, but when i connect, and try to navigate, it stops again.
I have tried almost everything (move slider of power to the left...).
I am not sure but i think it only happens with some wifi's...
Any Help? Thanks!

Hi, I've got the same problem.. I was able to connect to the wifi at my school last month and works perfectly, but then suddenly this problem comes in.. anyone can help?

Hi,
Same here.
WiFi works fine at home but it only works a few seconds in my university.

Hi,
My device does this too on occasion, I've gotten around the habit of resetting the phone every two-or-so days.. Keepin it working.
Does anyone know how to set proxy settings for the wifi?
I can set them for other connections, but that..
Would be nice to have one set of settings for each SSID or something?

Try to disable power saving for wifi.

Wifi connected..Signal strong..

Ok so tis is my problem. the Wifi connects fine. i use it for 10 minutes...20 minutes..it works.. then suddenly.. it stops working?
I go to comm manager the Signal quality is full or 3/4 full (dependent on location). it stays connected... the tx rate is 54Mbps and the Rx Rate jumps between 1-54Mbps.. My network is not security protected but no one uses it except me and my computer.
Im using messeneger then it says " messenger trying to reconnect blah blah) then i go to opera and it stopped working too...but its still connected, the signal strength is still strong?
Whats going on?!
My router is a Netgear DG834GT.. I have put my xperia's mac address on the allowed list as well.. i just dont get it?
i have to disconnect and reconnect to get it working..then it lasts another 5 minutes and dies again? Sometimes when i reconnect it still doesnt work so i have to turn off wifi and turn it on 2 or 3 times?

You are not alone, my friend. That's exactly what happened to me, except mine is Belkin.
Someone here (sorry I can't remember) suggest turning off bluetooth solved the problem.

i would try upgrading the firmware of the router it solves many incompatability issues for many people
sometimes my linksys drops data connection so the wifi signal is just a pin
and only fix is to unplug the router for 10sec and replug it
seems to be common that wifi act up at least see people complain in many many forums for wifi able devices

bluetooth is not on at all... Also every other wifi device will connect just fine? why would it work then just stop?

I have no idear only knows that what i wrote fix it in many cases for many people

i have wifi on even in standby tweaked...did you guys tweak anything? like auto off or anything?

nop i just use wpa AES
but as i said i update my wifi router with the latests firmware when
ever linksys updated it and believe me they updated it often

is anyone facing this problem or faced it before then fixed it?

if it's not your router as Rudegar suggests (one way to test, try over a different wifi elsewhere) then I wonder if your wifi is powering down for some reason?

Hey guys...having the same problem. Firstly I had trouble connecting to Wifi with the Xperia...then I updated the router firmware...now I can connect to Wifi but it does nothing, I cannot surf the net, I cannot connect to Skype I cannot connect to Windows live, cannot check my mail, etc...
Any ideas? Bluetooth etc not on at all...

[Q] Desire Z looses Data link following USB Internet Pass-through.

Hi,
Not sure if anyone else has experienced this issue so here goes.
I regularly connect my Desire Z to my PC in Internet Pass-through to get data for updating apps and Navdroid map updates.
No problem connecting and the data throughput is great.
However, once I have disconnected the phone from the PC I have lost 3G/HSPD connectivity. The only way to get these back is to restart the phone.
I have tried turning on Airplane mode, and then turning it off - no success.
I also tried turning off data and then turning it back on - no success there either.
Is this a known issue or has anyone else come across it. Anyone found a solution if they have, bar restarting the phone that is.. ?
Thanks,
Des. . . ; )

Yeh this also happens to me, though only sometimes. Unfortunately, all I've been able to figure out in terms of fixing it is just restarting.
Data connection is not the only thing that glitches for me with internet pass through, sometimes the other types of USB connection stop working as well (e.g. the phone will not be seen by my windows machine when put into removable drive mode after being in internet pass through) until I restart. Essentially, even though internet pass through does not always cause problems I always restart after using it since it seems to be good at glitching other things out and probably messes up things I don't even notice at first.

This has happened to me several times...
What I noticed is that whenever I disconnect the phone while it is in Internet Pass-Through mode, I couldn't get my mobile data connection to work afterwards..
So before disconnecting, maybe you can try changing your USB connection mode, say, to Charge Only. When disconnecting from that mode, mobile data works.. at least in my experience..

Hi,
Might be worth a try, that. Czechton can you try and see what sort of results you get?
Thanks,
Des. . .

I will second that - this problem occured for me everytime I connected the phone in the "internet pass through mode" - I also noticed (although I did not keep track to check if this solves the problem EVERY time) that if I change to the "charge only"
mode and then disconnect - I get back my mobile data connectivity back

Heroine loses Wifi when screen off

Hello everyone
I am seeing a strange behaviour of heroine rom, when the screen is turned off the phone loses the wifi connection. I have tried to set it to never switch off wifi but it seems ineffective. I was wondering if I could fiddle some other settings to sort the problem out.
If I reflash with the same rom, will I lose all the installed apps/phone numbers, google apps?
I am currently not in 3G nor gprs coverage so I can only use wifi.
thanks

Configuration
Hi,
I had that rom on my hero and works fine, i remeber that there is a configuration in setting of WIFI when you can change a wifi sleep policy, try it

hello
it is already set to keep wifi always on

I tried to install an app to keep wifi on, called wi-fi keep alive. Unfortunately it does not really work.
The phone disconnects after the screen goes off, in around 2-5 min maximum.
I tried all the workaround, including the ping option, but it is simply ineffective.
any suggestion? idea? config file to edit?

Wifi and 4G stuck together - how to fix this?

I know i'm not alone since i've seen this issue not only on my phone. When i'm at home my phone is mostly connected to wifi. My router is Linksys AC1900. Sometimes both the wifi and 4G icons appear together. when this happens my battery is draining like hell. a simple restart of the phone or the router is not a solution - i found that in order to make the 4G icon go away i need to first turn off the router so the phone is connected only to the mobile network, than i have to turn off both the data connection and wifi of the phone; than i need to go and clean the cache through the builtin recovery menu. the problem is that sometimes even performing all these things is not enough and the 4G icon won't go away. Download booster and Smart network switch are both turned off, but playing with them do not really affect the issue. also i tried connecting to both 2.4 or 5ghz wifi with no difference. i also tried setting a fixed IP address for my phone, but again this does not affect the issue. any ideas? i'm pretty certain that it's not a hardware issue since i've seen it happening to other people too. it's quite annoying since it's totally destroying the battery life of the phone and it seems that there's no real solution for this behavior.

What model number is your phone? Have you considered reflashing firmware / factory resetting the phone?

The model is 935f. I've tried reflashing with stock several times (the phone is not rooted) but after a while the problem comes back. This is the only issue I've had with this phone but it's quite annoying.

I've got the same issue. The only solution i've seen till now is to reflash with a custom rom.

Same

I have picked up the same type of issue. I did some snooping around and have found that if I have my mobile data on when in the streets and when I get home and I turn on my wifi, that if my wifi signal is very bad and my mobile data is on, then it would show both signals. It's as if the phone tries to get whatever data from both, since the wifi is so bad. I agree that it really chows the battery. The only fix I could get to work is to switch of the data and move closer to the wifi where it's the strongest. I will sit at the router for a minute or two, It then automatically removes the 4g sign and only works on wifi. If I stay where the wifi signal is bad and disable mobile, it stays there even though my data is off.

Did you do a factory reset and restore your phone to its original settings?
