xperia wifi problems

i have a linksys WRT54GX4. When I try to connect to it using the xperia, it tries to connect for a few seconds and then the status shows unavailalbe then a couple seconds later the status of the router goes back to available but i can never connect to it. The router is running a DHCP server and the wireless security is WEP 128bit and the authentication is open. I don't know why it doesn't want to connect. I really need to sort this out. Anyone else experience this problem? The phone connects to other routers in my neighborhood though, so it might be the router, but i have other devices connected to the router and they are just fine.

Haven't used that router before but maybe you could try updating the routers firmware to the lastest available.
These should be available from the manufacturers website.

already tried its the latest.th erouter isn't giving me any problems on my othe computers/ laptops. Is it possible that the x1 just isn't compatible with it?

Do you have any other security, i.e. MAC filtering, turned on?

no i never mess with the more advanced settings. BTW I even tried disabling all encryption basically unprotected, and it still gave the same problems! Thanks for the quick replies also.

Hmmmm......
Ok, I know its a pain but try changing your security from WEP to WPA.
Everyone with wireless should really use WPA or above, WEP is quite crackable with various free tools floating around the net.

yea but shouldn't it have connected with NO encryption whatsoever?

Hpoefully a hard reset will fix your problem?
I had the same problem but i thougt it was becuse ny router but i tried to connect to other networks aswell an got the same problem, well later on my phone stopped accepting files thrue the usb cable. and didt want to install some cab files that i had istalled before and knew was working.
I had enough and decided to hard reset it and it really fixed all my problems.
so hopyfully it will for you too..
Good luck.

yea i'm gonna try now, hopefull that will work, did u hard reset thorugh the iption in settings, or did you do it physiclaly through buttons>?

Havent had that problems ... what i do is allow only my devices mac address to connect ...
my psp as well as gf psp
2 desktop + laptop
htc touch cruise
xperia
and home media player
Everything else gets denied, cant really beat mac address filtering.

ok just tried a hard reset and still didn't work. The signal strength is full but the phone never even gives me that automatic message that there is a network available, but it does this for other routers in my neighborhood.

Actually, you can, but that's for another forum

OK PROBLEM SOLVED. Did a factory reset on my router, then the phone connected. But when I went to change the channel from auto to 10, the wifi stopped connecting. After that, any susequent changes to the channel; whether I tried a different channel or set it back to auto, did not work and the only way to get it back was factory reset the router. So basically I have resseted my router, and have not touched the channel settings and it is working fine. BTW the dedicated Xperia tech support line is AWESOME, even though they weren't the ones who figured out why i had the problem (and they wouldn't have because it was the routers problem) they knew what they were talking about and are actually from the US!

n4v1n, did WiFi work for you in other networks (with other routers)?
I have the same problem with my phone: only reset of my house router allows the phone to reconnect.
I am not so convinced that it's a problem of the router, because two of Samsung phones (Omnia HD on Symbian and Wave on Bada) connect always without any problem.

does your router have a physical easy connect button? try to use that before connecting even you already have the proper setup on both devices. sometimes somehow that happend to laptop, phone, wifi card. and with a single push solved most of the quirks.
if i remembered correctly, older wifi support only up to 7-1 devices. and my phone seems never connect to anything higher than channel 6.

Wifi Problems

Well I've had my Captivate for 3 months, and up until now it's been smooth sailing. Two days ago I came home and my power was off, and when it came back on I tried connecting to my router like usual, but now it won't connect. On the "wifi settings" menu it just says "obtaining ip address from..." for a few seconds then it says "disconnected" and goes back into "scanning..." mode. Also, under the "wifi networks" section it shows my network as "Disabled, secured with WPA/WPA2 PSK". (I am using a Linksys WRT54G with WPA2 security f.y.i.)
I've tried "forgetting" the network, I've deleted the whole file that remembers your networks, I've tried connecting via WPS button, I've double checked my password, I've power cycled my router, I've reset my router back to default and re-configured it...still nothing. It connects to the wifi on campus with no problems (in 4 different buildings), so obviously there is something wrong with my router setup.
If anyone has any advice on how to resolve this problem, it would be much appreciated!
**Also, I forgot to mention I am running Cognition v2.2 Beta 6

Bump for hope

Happened to me a few times. Only way I could get out of this was to restore to a previous backup, or install fresh again. By the way, I experienced this problem only on 2.2. Never happened on 2.1.

Unfortunately I don't have anything else with wireless to test.

Elaborating on the issue
I've encounter exactly the same problem described here.
Samsung Galaxy S I9000. Froyo (official version). Not rooted.
Now it is the first time it has happened, and still I have not found a solution (restarted the router, restarted the phone and made more tests).
Before the upgrade to Froyo it has never happened. After the upgrade it worked ok for several days untill now.
Several other deviced at home are well connected to the router.

Its just s stupid suggestion maybe... but have you tried to change channels with your router?
Sometimes is just a stupid channel issue....

I found out the answer to this problem. I had to connect using static addressing. It seems at some point, the captivate 2.2 roms get confused for some of us and it starts trying to assign an IP address already used.
In my case, I tried everything... rebooting phone, router, ect.
Laptop connects fine, Wii connects fine...
But, I decided to connect via static addressing... BAM connected perfectly and instantly.
Connecting to other DHCP networks seems to be hit and miss as well.
So, I'd suggest reflashing might be the overall fix. But if you're like me and cannot reflash right away, try static addressing till you can get around to it.

Not stupid at all, but unfortunately yes, I tried a couple different channels and still nothing.

Awesome! This sounds like a promising solution, thanks. Yeah I need to reflash soon anyway seeing as how Cognition is up to 2.4.x already...
Probably won't be tonight, but I will do this soon and let you know my results.

Alright, I have typed just about every keyword into google relating to setting up my router/phone to use a static IP and for some amazing reason there are ZERO results that have any information whatsoever about setting up a static ip on a phone. This is really frustrating, so if anyone would be kind enough to explain how to do this or link me somewhere that does, that would be awesome

go to your wi-fi settings and click the menu button.
it should pop with a "scan" and "advance"
click on advance and scroll down to "use static ip address"
then i guess you have to put in your network details, not sure on the details there cause i have done it but experiencing same problem with my galaxy s
power went out and now can't connect to my network
Edit : Possible fix
I just managed to connect to my network.
I put the device in flight mode and restarted my modem at the same time
put it out flight mode and pluged in the modem again and now works.
Hopefully that works for you to guys.

Yea, works perfectly. I have my laptop connected to it right now. I usually have to reset the phone to get wifi again.
edit: I set it to static ip, but then i got the same problem. Except now google search engine works No webpage opens, youtube app didnt work either.. only the search engine worked.

Well my phone must be in a good mood today because it just decided to start working again all on its own! I don't know what caused it...I have actually had both my phone and computer constantly on since this started happening. So for now I'm keeping my fingers crossed and hoping it doesn't mess up again.

This is probably just for me, but this isn't a viable solution.
The ONLY router I seem to have this issue with is the one that Verizon gives all it's FiOs customers. It's the Actiontec M1424WR Router/Modem. I know my WEP key is correct because it works just fine on all the laptops and other phones (a Palm Pre and another Captivate on 2.1). It tries to obtain an IP address for about 5 minutes and then just sits and says disabled. Does anyone know if there's a way to dump the DNS cache or whatever like you can on Windows?

Add me to the list of ones having this problem...guess I'll try to reflash everything in a bit to see if that fixes the problem.

Just an update I backed up everything using Tibu and then just restored it and my WiFi problem went away.

Mine is stock and just started having this problem....will connect to other wireless routers except mine, really pissing me off!
I've tried many times having the the phone "forget" me, then put in my password(which is correct)...same thing over and over.

Same problem here
I have a galaxy s and the recent update to froyo brought me the same problem already described here.
And the "funny" thing is that my router doesn't have an Static IP option, it's a simpler router from the cable provider.
So i'm trying also to find a solution to this. Two days ago i changed the wifi channel and it worked. But today i have again the same problem and changing the channel don't work anymore.
Each time i find a possible solution, it only works one time.
This is really annoying me. This must be a froyo bug, 2.1 never gave me this problem

It must be a froyo beta bug. Remember we don't have a final version of this firmware for the Galaxy S family.

[Q] Captivate Wifi Issue

Hi All,
I have a weird problem with my captivate of not connecting to my home network. Let me start by telling that I have searched the solutions and tried doing everything except full factory reset. I have rebooted the phone, done reset on my router (Wifi was working just fine earlier.. so I think settings was not an issue. But I still did it), I removed the file data/wifi/bcm_supp.conf and let it regenerate it. Captivate displays "Obtaining IP Address" and it just stays there. I also see that IP address is being assigned to captivate in my router
Captivate is rooted stock Froyo
Router security: WEP
form the Wifi list, I found one unsecured network and captivate connects to that router just fine (signals are very week though...). I tried removing the security on my router but it still stuck on "Obtaining IP address".
Can you please please help me?? As I mentioned earlier, It was working just fine and suddenly stopped working two days back.
These all app updates are eating away my limited data of 200M.
Thanks a millian.

What's your router model ?
What channel are you running on ?
Are others routers close to you running on the same channel ?
Have you tried another channel ?
Did you try WPA2 ?

Could be incompatibility with your router. That happened to me before with my old router. It didn't work with some cell phone wifi devices.

Try using the app "FXR." I had the same issue a couple times and this app seemed to fix it. It took a few tries though. I think it might be a router problem. I use the Linksys wrt54g.

You could also try assigning a static IP address to your device on the router side, and then telling your phone to use that address. I've used that in the past to some success.
As a test, have you tried (temporarily) disabling the security on your router to see if it connects?

I have a similar problem since upgrading to the past 3 nightlies. My phone sees and connects to my home network and says it has strong signal, but when I try to access Market or Internet it says there's a network error and I can't get thru. My two computers (one hard wired and one wi-fi) don't seem to have any problem hooking in to the internet, just my SGS1

Does the 'FXR' app set up IP addresses?

The App didn't work for me. I tried that yesterday. I was reading the similar problems on some other site yesterday and I found the following that solved my issue. In case someone like me still struggling with the WiFi problem.
Delete file data/wifi/bcm_supp.conf
Delete file /data/misc/dhcp/dhcp_list
reboot the device and it will create these files again and you will have to enter your WiFi password again in order to connect.
I am really glad that my WiFi is working back again.

FYI, I'd change the WEP to WPA.

Where do you go to change that setting? I've been all thru the wi-fi settings and advanced settings, but didn't see anything that referred to WEP or WPA.
Just realized we're talking now about the router, not the phone, duh!

Yes, I certainly need to bump up the security settings on my router.

I used root explorer, but could not locate the files you mentioned. Directories were there just not files. I'm still exploring the router side. Thanks for the info tho.

Droid can't see wifi router

I have an unrooted OG Droid running on stock Froyo (2.2.3). It's off-contract, but I have been using it by connecting to my wifi router (Netgear WNDR3700). Everything has been working fine until Friday when it stopped connecting to my wifi router. I tried reconnecting, but it cannot seem to find the router at all, even if I'm standing right next to it. My router does not appear on the list of available wi-fi networks when I look at Settings -> Wireless & networks -> Wi-fi settings. The strange thing is that it seems to pick up all of the other wi-fi networks from my neighbors without any problems; it just can't seem to find my wifi router.
All of my other Android devices (Nexus S, Evo 3D, Galaxy Tab, Logitech Revue) can find and connect to my router without any problems. It's just as though the router doesn't even exist from the perspective of the OG Droid. I haven't made any recent configuration changes on any of my devices or router. My other wi-fi devices (laptops, printer) don't have any issues finding and connecting to my router either.
I've tried rebooting, pulling the battery, etc. without any luck. Any ideas?

By chance did you unplug the router, my og DROID loses wifi sometimes and even though phone sees it won't connect but usually resetting router gets it to reconnect.

I haven't done that yet, because as far as I can tell, the router is working fine. The issue that I'm seeing differs from yours as the phone doesn't even see the router right now.

It's a bug in Android. Delete all the remembered wifi accounts on the phone and then you should be able to scan again. Once you scan, it should pick up the router again. Had this happen on a couple different android devices.

I gave this a try, but it didn't work. I can still see all of the other available wi-fi networks near me, but not my own router. Any other thoughts?

I've had this with my router whenever i reset it.
its because there are too many routers in your area on the same wifi channels . change the channel your router is on until its one with less or no routers on it and it will appear eventaullly.

I have same problem with you.
My LWW cannot find/detect the home wifi, but another device (laptop and samsung galaxy mini) can work well with the wifi network.
but my LWW can find another wifi network except my home network. but sometimes when I don't use the LWW for long time, and when I started to turn the wifi on, it can work well. but after I stopped the connection and start to use the wifi again, it cannot find the network again

I just had the same problem and fixed it.
Sometimes routers are configured to select and use the less crowded wireless channel. That can cause your wifi to eventually use channel 12 or 14. Like sleepyguy007 said, it is more likely to happen if there are too many wifis in the area and all channels are crowded.
As far as I know, Android devices are by default configured to scan only up to channel 11. So if the wifi is in 12 or 14, it will not be recognized.
Go to the wifi config screen, where all the networks are listed. There, with the menu button, go to "Advanced"->"Regulator domain" and set Android to scan all 14 channels, that should do the trick.
I hope that is the cause of the problem and you can fix it... Otherwise it could be a bug, and the solution may be harder

I'm so happy & surprised!!!
I had same problem and with your helps(phobophille & sleepyguy007) my problem solved:laugh: :fingers-crossed: :good:

Grey WiFi icon

Got me a new router from my ISP, of course there were issues instantly! Having problems connecting to wifi. Called my ISP and they said there is a bug somewhere in the router or in android itself. The router is a ZYXEL P-2812HNU-F1. They said I needed to get a static ip adress to each device. I got my Galaxy S2 up and running in no time, however, my HP Touchpad is not being so friendly. It says I'm connected but I get the grey wifi icon. Tried to disconnect and reconnect but no result. Also tried to forget the wifi and so on but no result. Also changed to b/g since it handles /n aswell. I've changed the router channel. In addition, my TP have begun to reboot randomly often in very fast cycles. I've flashed the Supreme mods a few days ago and everything worked flawlessly with my old router. Could the Supreme mod interfere with this maybe? Anyone please, this is so frustrating!
Edit: I'm on CM9 14 July build

The wifi icon color is blue when you're connected to the Google servers. I remember reading something similar to your situation, I'll post a link if I find it. Meanwhile, you've probably tried this, but in case you haven't, try turning the router off for a while, then turn it back on again. You might want to go to a later build, they're quite stable. I'm one of the lucky ones, only had any wifi issues once, and turning the router off then back on solved it for me.
Good luck.
Edit : Try deleting the Supreme mods, they might be the problem.

As you said, I've tried to switch off the router and put it back on but I tried it once again but no result. I've also removed the supreme mods but there is no difference. I still get the grey wifi icon. Maybe should try a newer build, so tiredsome though but maybe the only solution. Will call my ISP for a factory reset on the system aswell.
Edit: Managed to come up with a solution. My ISP wasn't of any help so I had to do something on my own. So, I changed the security to wpa instead of wpa2 and noticed that my tablet got connection! The thing is, I want to use the /n standard and wpa does not support that. So (again), I had to enable a second wireless network and luckily my router supports four. One network with wpa2 (laptop) and one with wpa (tablet). Not a pretty solution but it works!

I did read somewhere that giving the TouchPad a static IP address helped with a lot of WiFi problems, maybe its something you could try. I personally haven't had any WiFi problems so I have never needed to test it.

Made a little update on my previous post. The solution was that I needed to change the security on my network (wpa2 to wpa). But as you mentioned, I needed to set it to a static IP adress aswell. Up and running now, as I type at least

try running an atheros update. i also prefer wifi analyzer for connecting to wireless networks rather than the android wireless settings. It shows you detail and information that android settings do not. Lets you configure channel options for B/G/N and A. plus more. its avail in google play.
