[Q] wifi problems and some related questions

Hello
i have a htc desire gsm
and im running cyanogen mod 6.1.1 with radio version 32.49.00.32U_5.11.05.27
i have the following problems:
i can connect to networks without a problem, and the connection seems stable and fast
but reconnecting is a problem, if i disconnect from a network, by disabling wifi or moving out of range, most of the times the wifi does not auto reconnect. it just stays as remembered and disabled. if i then click on the saved network it connects fine.
sometimes it has to connect two times to get a conenction, looks like connecting, then searching then connecting in the wireless and networks config screen.
its not a big problem but annoys me as hell
on the other hand i have one network, protected with 802.1x eap (ttls and pap) its the configuration where you need to input username and password and use a certificate.
with this network i have connection problems, connection works 1 out of 4 times and if not then i have to redo the whole config. this annoys me even more because the network is unusable for me most of the time.
and
today i had the problem that the wifi conenction dropped regularly, connected, then came scanning which disconnected my wifi and then reconnected. and so on.
wifi settings even force closed then
had to reboot, after that was fine. lets see for how long
i have googled around but never found an answer or fix for this.
so can anybody help me here ?
and i have some related questions.
is there an app that can show me only wifi and related logs ?
is wifi connection related to radio version ?
where are the wifi settings located ? like saved networks and so on ?
thx in advance

I also have that auto reconnection problem. Waiting for a fix for that.

Does it manifest exactly as I described it or in some other way?

wifi problem 2.3.3

Regards
I have a problem with wifi after I put update on 2.3.3
whether it can solve this problem with wifi.
I always shoot and it turns the wifi network.
be a good wifi network signal then disappears

Same problem here

This is a very serious problem. Get ur act together HTC, this is just unacceptable!

Are you rooted? HTC raised the signal strength at which the connection would be dropped, there is a fix if you are rooted, otheewise you are stucm and will have to wait for HTC to correct this.

Have you tried another radio? of course be careful if you do change it

same issue, though htc say that its a "new feature" to provide a seamless mobile broadband experience by automatically chosing the strongest signal. whatever you say htc
i just disable mobile data at home, so it cant jump back to 3g and stays on wifi. the annoying thing with this is that i forget to enable mobile data when leaving the house.
i hope they sort it out, and that this new feature isn't rolled out across their other products

I am having the same problem. At work, my wifi connection is weak, but was always functional. Now, I cannot connect to my work wifi. On top of that, my battery drains twice as fast on my phone, and I'm thinking that it's due to the phone always scanning and trying to connect to the wifi signal. If it's true that HTC changed the level at which the wifi signal is dropped, this was a terrible decision.

I think this may answer/point to the problem I'm having since installing the Gingerbread RUU. I use the quick settings app from the market and pre-gingerbread it used to switch between wi-fi/mobile pretty seemlessly, turning off the unused option. Now if there's no wi-fi connection that option seems to stay on (probably searching) while it's connected to mobile data. As above, my battery is draining like a sieve.

Same problem for me with Original Rom.
so i tried the Revoloution HD 5.1.4 and same problem again!

Hi guys until HTC release an OTA fix (that's if they do) the only way to resolve this is to root and then try some different ROM and radio combinations until you find one that works for you.
I find the ROM and radio from my signature work really well on WiFi but if you are going to do this make sure and root, gain S-OFF and ENG S-OFF. Also make sure you have the correct RIL for the ROM and radio that you are using
There are lots of threads on the dev section that guide you through this.

Wifi connecting
I have a similar problem with wifi connection. Only it doesn't disconnect during a connection but when establishing a wifi connection it takes much longer than it used to on Froyo. Anyone else noticed this?

i have problem too with wifi

I really hope htc has stopped the updates and resumes with a new build with the wifi problem fixed

The issue is with the Gingerbread Sense ROMs.

WiFi problems with routers
Hi there,
Same problem here. Both my WiFi router and phone say signal and reception quality are perfect and connection it stable, but data won't flow.
I'm having this problem with my Speedtouch (WEP key) router at home, whereas a Sitecom router at the office works fine (WPA etc. key).
Tried some work arounds, without success
Regards
***EDIT***
I can add that it has nothing to do with the reported threshold of -88dB signal strength. As I checked that with the *#*#4636#*#* option and both higher and lower values of the WiFi reception don't make any difference. The problem persists.
***EDIT v2***
The suggestion posted elsewhere to change from WEP to WPA didn't work out either
***EDIT v3***
Reverted back to ARHD 3.7 and WiFi is running fine again .
Hope some fix will be found soon!
Regards,

Is there any solution. I am trying to downgrade the radio but no chance.

If I use LeeDroid or Revolution will this same problem be there?

[Q] Strange WiFi connection issue

This is a strange issue that I have not seen before. I was starting to have issues with my phone connecting to the wifi at the house. I decided to flash a clean rom today and hopefully that would fix the issue. I did a clean install and now my phone will only connect to the 5G band and not the 2.4GHz wifi band. I would like to connect to the 2.4ghz band but I get a message saying authentication error. I removed the connection and connected using the wps push button but when i do this it only sees the 5G. Any ideas what is going on and how I can correct it?

Do you see the same issue on the stock build ??
You are running what rom ??
Try the rooted stock build as a test. ..and if no change. ..reset the router and set up the connection on the device again. ..g

Have you tried turning off the power saver?
I suspect your router as the culprit but you can try going into the advance menu.
Hit *#0011#* hit menu then wifi menu.
I think you may even be able to choose the band? I think you can choose auto or manually pick 2.4 or 5ghz. Either way see if shutting off the power saver helps.

That is strange usally its the other way around...I have my dual band set up similar to yours..I named the 2.4 actually 2.4 and 5.0 same password..sometimes ill have to hit scan to show the 5ghz band...sounds stuiped..but make sure you click show password and make sure your entering rhe correct one..it may be so simple you may entered wrong password...or try changing the channel on the 2.4 ghz in rhe router setring to a different channel..mybe be a conflict..change it to channel 11..and reboot the router. ..

I have tried it on a stock rooted rom as well as CleanRom 3. Does the same. I have not tried a CM based rom to see if it only does it with the TW based rom's. I have checked the router and I don't see anything there that should cause the problem. I have 4 other android phones, and android tablet, and 1 iphone in the household and none of the others are having this issue. I have also noticed that it doesn't always say authentication error. Sometimes it says out of range even though I can be standing right beside the router. I am stumped.

Did you ever solve this? I'm having similar problem with my Note 2. I have a strong wifi signal incoming to the phone, but the transmission signal is very weak (verified using dd-wrt on the router and looking at client signal strength). My Note 2 has extremely poor strength.. ~10% where every other device on my network is ~50%. I've tried factory reset, turning off wifi power save mode.. not sure what else to try.

I am having a similar problem for the past couple months. My Note2 (ATT) with custom ROM won't connect to a 2.4 GHz wifi. No problem connecting to 5GHz wifi.
I saw an answer to this for a Sony Experia that the problem is with 802.11 mode and to change a file option gDotMode from 3 to either 1 or 2, but I haven't found a file with that option in it yet.

Same problem here, no 2.4 authentication unless the phone is very close to 2.4GHz AP.
Same problem here, no 2.4 authentication unless the phone is very close to 2.4GHz AP.
I have noticed that in some public networks i can connect with no trouble, (I guess now that they're 5.8GHz)
but not at home
Any solution? I am using a note 2 i317m with stock rom 4.3 from TELCEL mexico carrier

WiFi connection is stable, but Internet isn't

WiFi connects to my router and stays connected at excellent signal strength without any trouble. Internet connection however, always disappears after a minute or so. Then my Dolphin Browser either keeps loading a website forever or gives me some error like "Webpage not available". Same story with stock or any other browser. I'm not sure since how long I have had this issue. It surely existed already when my phone came back from warranty service (and I had sent it there because of very short range of WiFi commonly known problem which they fixed by giving the phone new hardware). I think that upgrade to Android 4.2.2 might have caused my problem, but it was such a long time ago that I don't remember now (I don't use/need WiFi that much, mobile data internet is enough for me).
What I've tried so far:
-rebooting phone and router obviously
-factory formatting the phone
-WiFi analyzer app
-changing all the network parameters and re-setting it up
-WPS connecting
-playing with all the WiFi settings on my phone (proxy settings, ip settings, wifi optimization and other)
-finally, today I unlocked bootloader, rooted and installed custom ROM hoping it'd help (but it didn't and now I lost my warranty lol)
What I have:
HTC One X Endeavor
Android 4.2.2 HTC Sense 5.0
Android Revolution HD 33.1
3.1.10-g7f360be Kernel version
TP-LINK
N750 Wireless Dual Band Gigabit Router
Model No. TL-WDR4300
I'm thinking about installing other ROM, some that works on Android 4.0 or KitKat, could it help?
Oh, and I should add that two different notebooks, Galaxy S4, S3 mini, Xperia X10 and a tablet all work fine with this network :>
I can provide any screenshots, photos, names of devices etc., just tell me what is needed.
HELP!

WiFi issues: can't connect to any network anymore [T800]

In the last 6 months or so I have been experiencing frequent wifi issues, regardless of the custom ROM I'm using. Usually some time after a new installation I am unable to connect to the networks I normally use (my home network and the one at work which uses a proxy server). No matter what I do (clear cache, factory reset, change ROM...) the problem persists. In settings a number of random messages are given: secured, disabled, authentication problem, etc. Every now and then I can get a connection (never at work though) but it doesn't last long. Any help for troubleshooting this would be appreciated. I hope it isn't hardware failure since I'm still enjoyng this tablet after all these years!

Mine started having wifi issues off and on a couple of weeks ago. The wifi started to not turn back on after waking it up, at first just in manually turning it off and then back on seemed to work. Last Friday it just wouldn't stay on at all. I would go to the wifi in settings, it sometimes would get stuck saying turning on. I finally did a factory reset on it, it at first seemed to fix the problem, even spent a couple of hours trying to get everything set back up. Then the problem returned, it just keeps turning the wifi off, if i can even get it to turn on at all. I was going to try and use my phone as a hotspot through Bluetooth (not sure if i can or jot, never tried before), but even the Bluetooth won't stay on. So Sunday, after spending way to many hours fighting with it, i went out and got a new tablet.

Have you tried using the Samsung Kies app to flash the latest stock rom, Dont use Odin or other non Samsung approved flashing software.
I have had my T800 for over 4 years and had no real problem with the wifi connection, But i have heard that there can be compatibility problems with some wifi routers, Also try changing the channel number on your router, Auto channel was giving me poor connection on my PC, I ran the inSSIDer wifi app and it said to manually change my wifi channel to channel 1 the clearest channel as other wifi and bluetooth and wifi dongle even you smart gas/electric can cause interference., auto was picking channel 13 for some reason and it fixed my problem.

Thanks, but since it's the router at my workplace there's not much I can do on that side. Question is, are there any specific steps I can take to verify if it's software-related or if the wifi module is just gone?

Wifi and Bluetooth both use the 2.4ghz frequency, So they can interferer with each other and can cause constant disconnect`s, I have seen this many time, Use 5.0ghz on your T800 if you can, Or disable Bluetooth.
Does your wifi work OK on other brands of router?, Or is it just the one you are using at work.
John.

It's kind of tricky to answer: let's say the times this issue appeared it always stareted at work, but then also at home I couldn't keep a stable connection. Once the problem starts, I get no connection at work at all and very difficult connection at home (meaning it does connect intermittently).

UPDATE. After other attempts and a complete restore of stock firmware, I have both wifi and bluetooth not working, constantly "turning on...." but never activating.
