[Q] WiFi problems after Froyo update

After installing the Froyo update yesterday I seem to be having troubles with my WiFi connection. The connection is being dropped after a half an hour or so and I'm unable to reconnect at that time. The Desire just keeps connecting and disconnecting to my network.
I need to reset my router in order to re-establish the connection but it gets dropped again after a half an hour.
I did not experience these problems on the previous version, I did however experience something like it when I connected my PS3 to the router via WiFi in the past. After I done that I wasn't able to connect on my laptop. But I switched to a cable for the PS3 after that anyway.
Is it possible that something on the Desire triggers an overload in the router that causes it to malfunction? I'm unable to connect with my laptop when the connection is dropped on the Desire as well.
It's a Belkin f5d7632-4, which is actually a modem-router, but after disabling the DHCP server it functions fine as a wireless router.
Thank you in advance for any ideas.
If I can't find a solution I think I have to get a new wireless router, I can't go without WiFi on my Desire at home!
If that's the case, advice for a new wireless router is welcome as well. Please post the brand and type and if it's functioning fine with the new Froyo for you.

I have the same issue. I went from standard, unbranded 2.1 to OTA 2.2 like a good citizen, but now it won't connect to my belkin wirless N router, but it DOES connect to my SKY netgear router.
What's the deal?

Yes, I've spotted some more Belkin N1 users on (the dutch website) Tweakers.net with the same problem.
I retain a good connection for about half an hour. They seem to be having the same problem right from the start.

I have a similar problem with a BT HomHub 2.0 but it drops the WiFi randomly however I do not reset the router just turn the WiFi Off and On on the phone and the Desire reconnects. My Desire will also change which SSID its connected too, i.e. from my own SSID to BT Fon or BT Openzone (I have them both turned on in my Home Hub) again to get back to my own SSID I have to stop and restart the WiFi on the phone, simply asking it to move back to my own SSID doesnt work.

Just had a call with HTC Netherlands and they advised me to try it on a different network/router and/or do a factory reset to a clean 2.2.
Has anyone tried the factory reset? I doubt that will do any good. A different router would seem to work according to Jammy1 (and I didn't expect otherwise).
Apparently something killed the compatibility between Belkin routers and Android 2.2 ?!

do you guys have the Bluetooth turned on?I realised when both the Bluetooth and Wi-Fi are on at the same time,the signals tend to clash thereby resulting to connection loss. Though,I experienced this on another android device (a tablet:Archos 5 AIT) especially when a major update occurs.Still waiting for my new Desire.

Random drops also on Linksys WRT54GL with Tomato firmware...

No Bluetooth here. Never even used it.

Try turning off the bluetooth.

Bought myself a cheap Sitecom WiFi router and it works like a charm now. But I hope HTC wil fix this and other little bugs present in this version.

I had similar problems after upgrading to Froyo (custom rom) - the Wifi seemed to get connection then as soon as I tried to use it within the browser it dropped and tries to regain IP. After a bit of fiddling with settings I have found that
i) using channel 12 (12 and 13 are only available if router is set to America location) to avoid conflict with heavy wireless coverage in my area seems to help
ii) using WPA2 encryption seems to give a much stabler connection over WPA, although now and again it forgets the passkey data, even re-entering it fails, only solve was to turn wifi off then on for it to reconnect

still having this problem...
does anybody have some news on this ?
I can connect to my home router a linksys wrt600n with WPA2-PSK key but i cant connect to a belkin N1 with WPA2-PSK enabled.
I tried every setting on the belkin router, just cant get it to connet.
My device just keeps connecting and disconnecting, it gets an ip but cant connect...
What i haven't tried is setting a maual ip and see if it connects then.

If i set it to manual ip, it works.
Does anybody have some news on this ?

What channel is your router on? Read somewhere about it not liking anything over 11...

I've been having the same issue on my Desire and on HD2Android.
If a 2.1 ROM is loaded into either of my devices TKIP and AES work perfectly.
With 2.2 it only connects through my Marconi router and doesn't obtain an IP from my Belkin N1.
I don't think this is a device issue but rather a ROM/OS issue. After speaking with some Linux guys they seem to have the opinion that the driver on 2.2 doesn't resolve it's IP address with some routers. Especially higher end ones with added features like QoS ie Belkin/Linksys.

Yes that was my initial thought !
But my linksys is newer then my belkin and it has no problems connecting my phone.
The 2 wireless routers are configured the same.
On android 2.1 i had no problems.

is it possible to try and install the 2.1 wifi drivers on 2.2 ?

i had the same problem 2 months ago when i first got my Desire. worked at just about every damn wifi router but the one in my house.
did some reading, no one had an answer. just seemed that it worked on some and not on others. so, i went out to the store and i picked up a Linksys after testing the linksys at the shop. my phone connected and had internet no problem. i thought, perfect, i'll take it.
brought it home, same problem. wifi connects and no internet. no setting would fix it. i brought it back to the store. and sure enough, we plugged that very router into their connection and my phone connected and worked. they obviously would not return the router because it works (and i live in a 3rd world country, forget about it).
so, **** if i could figure it out. i wound up using an older adsl/wifi router i had and no problems. but, i have a new linksys that is just sitting in a box...

its not your router, but the phone.
you can always sell the router on internet or the phone

I had contact with HTC Scandinavia and they also recommended a factory reset. But these guys haven't got a clue - they didn't even know this was a big problem after the froyo update. Weird when you think about it, I mean wifi is kind of a big thing for a smart phone.
But no, factory reset did NOT change a thing. And replying to other messages: this thing has nothing to do with what router you use. It seems totally random almost.

[Q] my Arc has wifi problem ?

Hi everyone i just bought my arc yesterday and quite satisfied with the good quality of my phone call but today i experienced a problem is that my Arc can not compatible with the Planet WRT-415 Router .When i connect to this router the wifi icon appeared on my screen but i cannot browse to the webs ,access to the android market or do anything relate to the internet (but others router at coffee shops or public spots are ok) .I also have the iphone 4, the ipod touch and when i connect them to this Planet router everything work just fine. i assume that there is something wrong with my ARC .So could you please help me fix this problem,thank you very much
my ARC info : Model LT15i
Android version :2.3.4
Build number : 4.0.1.A.0.283

I think you need reconfigure your wireless router. you can search this case in Internet.

perhaps you can check the DHCP least time?
the lease that 'never expires' might be the problem:
http://forum.xda-developers.com/showpost.php?p=17737923&postcount=761

i have done alot of research but still can not figure it out, i also set the DHCP least time to 1 week but it doesnt work,i think it is not the hardware problem but something wrong with the firmware because yesterday i installed FXR WIFI FIX AND RESCUE and some others WIFI FIX APPS ,my device suddenly work about 1-2 hours normally then disconnected until today ,this error really make my upset,
the others device such as ,Hd2 iphone 4 and ipod touch gen1 and my laptop are ok with the wifi from this Planet Router.ony ARC has this problem

i have done : 1)reset wifi router
2) change the channel from 1 to 11
3) install WIFI FIX APPS including FXR WIFI FIX AND RESCUE
4) reset phone settings
but no helps ,
anyone can solved this problem please help me

is your router running in mixed mode? my router was running in bgn mixed mode and none of my android devices connect. when I switched the router to 802.11g only or 802.11n only, all of the android devices connect again.

No my router is only running as g mode because i bought it long time ago about nearly 5-6 years ago so it does not have n mode, my problem is that my arc does not totally incompartible with my router ,sometime it suddently work then i can browse the web and surf the internet with my arc then i try to reconnect it in order to check if it is fixed then it is disconnect again. I feel really upset with my phone ,sorry about my english

Not sure where shall I post my question. Can't find an answer but decided not to create a new post when a wi-fi problem one already exists.
I am trying to connect to WI-Fi in my office but it's WEP encrypted with password.
I got the password to connect to it and everything is working fine apart from internet use. I am connected to wi-fi but with local access only. Can't update email, browse the web or anything like it.
Is it because the Xperia Arc S does not support WEP encryption? Or because I'm doing something wrong?

I do know that Android in general doesn't like WEP.

So in this case the only way to resolve the issue is to ask my company IT guy to change encryption, isnt it?
Are there any applications which could help with the problem or is it some kind of other issue and nothing can be done?

I am using WEP here at home, with no problems at all. I use my Xperia Arc and have an HTC HD Mini running Android from the SD card, both connect via WEP flawlessly.
If you can only view 'local' pages only, it could be that your company use a Proxy Server to filter the webpages you can access while at work. It could also be that the settings for the DNS server are incorrect.
Depending how easily your IT department can be bribed... It may be worth stocking up on beers?

it is not web or wpa the problem is the phone,but sometime i dont know why my phone suddenly work with my PLANET modem, because i used to leave the ARC with wifi on all day at my home sometime it can connect to the internet just like normal.like zombie turn back to life .i found that when i hear the notification ring tone when i receive new gmail at my phone ,so when i hear that tone i know that my phone work with my wifi.when i try to disconnect and reconnect at that time,i cant access to the internet anymore

I have the same issue with my Arc and Neo, and now Tablet S. Seems to be an intrinsic problem of Android. For Arc and Neo, they both worked fine with firmware 2.3.2, and refused to work after upgrade to 2.3.3. Now a further upgrade to 2.3.4 does not help.
Any inspiration? I searched the max possible I could for a solution with the Almighty Google God and tried days after nights to set/reset router/phone/Tablet, and play with settings. No hope. Strange thing to notice:
1/ Can connect for a while, and then drop for no reason. AND, will reconnect after an unknown time ticks;
2/ Cannot have all three SE/S things wifi connecting together to the same router (Mine: Buffalo). Only one at a time. Yet my other NBs/IPad/IPod are still working flawlessly.
3/ All three can connect to certain make of routers: e.g., free wifi in airport/cafe.
So what exactly is happening?

hi guys after 2 weeks finally i found out a solution for my home wifi internet then my android phone now work like champ .so i hope that something im about to write here will help you:
(i have 1 modem adsl named Postef,1 Wifi Access point named Planet WRT415)
here are what i did :
1) change the IP address of Modem to :192.168.1.1
change the IP address of AP to 192.168.1.2
2) change the channel of AP to 9
At the first time my modem and AP have the same IP which is 192.168.1.1 so when i use iphone4 and laptop to browse 192.168.1.1 it logged in to the Modem but my Android phone logged in to the AP so that is the problem ,the android phone can not distinguish if you use the same IP for Modem and AP

[Q] Arc frequently disconnects from wifi

My Rooted World Generic Xperia Arc 2.3.4 disconnects frequently from Wifi. It does not stay for even few minutes. I have setup a wifi connection(WPA2-PSK) by sharing my PC's wired internet connection(1Mbps) through a Wifi usb Dongle(Netgear WNA1100) and Connectify.exe on Windows 7. This kind internet sharing worked perfectly on my other sony ericsson java phones(Aino,W995). But Arc disconnects frequently. I'm trying to download the remaining data(458 MB) of Asphalt 6 3.55 HD with the WiFi connection. Where is the problem ?

same **** as usual, doesn't like PSK. Restart your router

use WPA2 with AES, i had a lot of problems using wpa2+tkip (every android device i have has problems with wpa2+tkip)

You're using netgear, likely the problem, get a decent router. Lots of dropping complaints but we should really make a thread and find out good and crap routers, my tomato routers the phone never drops out with.
Sent from my LT15a using XDA App

I'm Not using a router. I'm using usb wifi dongle. I'm using connectify on PC to allow my wifi usb dongle to share the internet connection. Can u recommend any similar softwares that can play with security techniques ?

So there is no way to rectify this problem ???

How to force 802.11g on custom rom?

Hi guys, I'm having some serious issues with my DIR-655 and my Gio.
For a long time I was using the first Particle rom and all was fine. Ever since I've updates the ROM, the troubles started.
I've tried pretty much any ROM out there, and all disconnect from wifi.
The thing is, I do not see the Wifi icon disappear. There is just no internet for some reason, Wifi is still connected.
I can solve this by putting my router on G only, but if I do that I can't get full speed on my or my wife's laptop (both 802.11n).
Is there any way to force my Gio to connect through 802.11g, now it's connected through 802.11n.
Putting my router on G only is no option, I pay for high speeds so I wish to use it.
Many many thanks in advance.

had same problem like you did with my first router. i forgot the model. but was pretty much the same. the router worked perfectly with my laptop. in 2 month didnt get any disconnect on laptop. when i bought the phone it was useless. only solution that worked for me was to change it with a d-link.... sry the router is not compatible with the phone probably cuz of the operating system of the router.

This is a D-Link router. .

And before flashing to the newer 2.3.5 roms all was working fine.

[Q] Arc S doesn´t recgonize my wi-fi

Hello. I search the forum and the net and I didn't find an answer. I Have an Arc S, and the phone doesn´t seem to find my wi-fi. The strangest is that the phone recognizes other networks, and it was already connected at my network.
Already disabled all the WPA/WEP securitys, changed the name of the wi-fi network, Pulled the baterry out of the phone etc. My Computer is working fine over the wi-fi.
Strangest part is that my wife's phone (arc S) is doing exactly the same as mine. It all started with a electricity fail. It happened before once, but with a router reset was OK, but not this time.
Really messed up.. Any thoughts?
Thanks

Have you tried manually connect to your network?

Your wifes arc s works, probably the promblem is 99% on your phone. Try a repair on pc companion
From my sexy LT15i

Already tried a manual connection, but the network does not appear. My wifes phone is not finding the network as well....

Sorry for misreading
Some troubleshoots:
*Check your firewall on your router. Try to disable
*Change SSID/key -keytypes
*Check if your SSID us hidden, if so make it visible
*Frimware upgrade/reinstall on router
*Try other signal channels like 11, 6
Set auto if possible
Theres a app on store to find the best one
*Try other radio type, like b, g, n
Set auto if possible
*Tried to set up a static ip on you arc?
Settings > wireless and network > wireless settings > push menu button ang press advanced > check the static ip option and configure it
*Try a app to connect like wifi manager and wifi connect etc.
*Check device (arc s) settings/permissions on router
*Are the phone using the latest frimware?
**The last solution. Contact internet provider about giving you a new router (if they gave this one)
***Ultimate solution. Throw that piece if sheit out and get a new one.
From my sexy LT15i

probably your your wifi is ad-hoc mode
android stock roms can not recognize ad-hoc wifi mode . just access point mode .
if it is your problem you have 2 solutions :
change your wifi mode to access point mode
use customs roms like miui or cm

Hello All. I already tried all the above, excluding somethings that was impossible in my router (software update).
After changing every single parameter im my router, the one that worked was changing the ssid channel from auto to manual. The first channel I tryed the phone immidiatly recgonized my Wi-fi, and now I changed Again to auto and its working fine....
Dont have a clue why!!
Thanks for all!!

Is there any other router signals where you live witch your phone finds ?
Thats why, radio jamming together
From my sexy LT15i

Yes, there are some other networks with same brand of routers (same ISP provider), but with different names.
The strangest part was that it worked before, than with no changes other than the power shortage both phones stop finding the network... But now is fine
Thanks!!
