Connection lost while using WLAN

When i use WLAN the 3G/GSM connection is lost after a few minutes and i have to reboot the phone to get it back. Does anybody know why this might be? Could it be the Radio?

I think its turning it off because your connecting to the internet through the wifi, when you disable wifi it should re-enable the 3g connection, but if it doesnt you can turn on the data connection...
thats what it sounds like is going on from your post. When I turn on wifi it will drop the data connection but has always reconnected to it once I disable wifi or I go outside of my wifi's range and something try's to connect to the net...

Yes, it is logical, you could not have opened two types of connection concurrently. One type closed another one.

ive had the same problem, when i connect to wi-fi i lose the data connection and it doesnt let me browse until i turn wi-fi off...i dont understand the point of wi-fi if u cant browse with the speed since the data connection is lost?

Thanks men! By turning on the data connection after i used wifi it reconnected!

What Wifi allows you to do us connect wirelessly to another connection, at home its my DSL, which is much faster than the edge network, and if I did not have an unlimited data plan wouldnt add to my phone bill. In that way its very usefull. Seeing how its faster and available at home or in places where your cell signal might not be strong or available you can use it to get online.
But you need to tell it your no longer using wifi for it to reconnect through the network to deliver data to you again.

ok so when it comes to wi-fi im a big newbie, i have a tmo wing and have flashed (upgraded) rom...i also have dsl at home how is it i can connect and access this...when i search for wi-fi it usually only picks up my neighbors connections never my own...?

If you have a wifi router or your modem has a build in wifi option you go into your modem to set it up. Most modems / routers come with it broadcasting the SSID so you should see something (usually the default is the name of the manufacturer)
If you have your paperwork you can open your web browser and type in the address to open the internal OS and make changes as you see fit. For example mine is a linksys and its default address was http://192.168.1.1, most routers used to default to that but since a lot of modems are coming out with build in os and firewalls they have that IP so routers can be changed like mine. Once in the OS you can set up your pw so no one else can play with your settings
Navigate to the Wireless section and there should be a bunch of settings. I renamed my WiFi name to match my home network, and disabled the SSID broadcast. Then changed the chanel for some of my other devices, if you dont have anything that requires this leave it alone. Then enable WEP or other protection, 128 bit wep is pretty decent and anyone hacking through it will probably be disappointed with your lack of juicy goods.
Once you have the SSID and the Key encription you go to your phone and mirror the information into the WiFi settings. The web will be a 26 or so string of letters / numbers that will equal the password you set. These must be typed in perfectly or it will not work, took me 6 or so tries to get it typed in correctly but once its in you wont need to do it again unless you reset the phone or change the network settings.
If all that goes through open IE on the phone and hit up google or something, if it loads your online.
Thats a jumbled and messy tutorial, I can fix it to be more user friendly if you need me to do it, but with you not seeing any SSID but your neighbors your wifi is either non existant or disabled...

thanks for the quick reply, ill give it a try...might need the more user friendly version lol sorry

Its no problem, the biggest thing will be weather or not you have a wifi router or modem. Then depending on the brand the IP you have to type in to log into the modem. Each router / modem will have paperwork with it that tells you how to do it, some are different but thankfully most are the same.
The un is usually blank and the pw is usually admin, sometimes now they dont even put one unless you specify it. Once your in the OS its pretty self explanitory, there are lots of things to not mess with, but in the wifi area you can look over my post and figure most of it out,
if you get hung up on somethin just post what it is and ill see what I can do

Wireless Wierdness

Help!
I have a Netgear DG834T router as provided by Sky. I have one wired and two wireless connections running into it (let's call them WD, WL1 and WL2 respectively).
On the connections page I can see all of them under "attached devices"...but now I want to connect using my Kaiser (actually an O2 XDA Stellar)
What happens...
On the Kaiser, I get an IP address (assigned by DHCP) as normal - but can't access the internet - or at least, can only access it very rarely - http://www.google.com can't be found, but http://www.bbc.co.uk can. No idea why.
On the router, under "attached devices", not only can I NOT see the Kaiser, but WL1 and WL2 also disappear. WD remains visible. The router cannot ping the IP address of the Kaiser (timed out). If I disable WiFi on the Kaiser, then WL1 and WL2 are immediately visible again. Internet connection on WL1 and WL2 works, even when they are not visible.
I HAVE connected to this network before without any problems.
What the hooting heck is going on, and how do I fix it?
Thanks!

Time to troubleshoot! What happens with this phone on another wireless network. We need to determine if it's the phone or the network. Do you have any friends with a phone like this? Can you use their phone on your network? Do you have any ROMs flashed, has this phone ever been on the network without problems?
If the phone works on another router try looking for firmware updates for the router. Those things really do need to be updated often and it could have something to do with that.

Only have access to one network :-(. Might be a couple of weeks before I can access a hotel one or something like that.
Think next door neighbour has similar phone, but different provider...will try if he'll let me!
No ROMS flashed.
It connected fine when I first had it. As far as I know, I've changed nothing since then.
2 out of 4 answered...with an option on three...I'll get back to you as soon as I've beaten up my neighbour and stolen his phone...
Joke!

There should be somewhere you can go to test that wireless. I can walk outside the building I'm in and find one.

You = US, me = UK. We still think the biro is a recent invention...

Neighbour's phone on my network gives the exact same problem. I've also noticed that when I click "Renew IP" on the Kaiser it doesn't work...it gives me 0.0.0.0, but will occasionally flash up the correct IP address. It's alomst as if the connection is being lost and remade every few seconds. The status ist gives me is "associated to network"...is that different to "connected"?
I've been trying to solve this on my router, but none of the settings seem to make any difference.

Same here
I get the same with the router from sky.
Kaiser says I have an IP address, 192.168.0.5, but the it doesn't show up on the attached devices on the router.
What I find that works is hit renew IP maybe twice until you get a really wierd IP address like
169.254.*.**, actually not sure if I'm picking up another network, but for some reason I don't think I am.
I can then browse the web and sync via wifi.
Really pisses me of that it says that it has an IP address but doesn't connect.

1) Make sure you dont have a proxy set up on your wifi connection on your device.
2) The 169. address is your device getting an unauthorised IP address as the router did not receive the correct encryption key from the device.
3) You can check if its an encryption thing by simply logging in to the router (192.168.0.1 in your web browser on pc) and changing the settings to turn wpa off and testing it. The routers username and password are on the card - its something like "sky" and "admin"

Yeah I agree, there is something up with that router.

No, proxy set-up as the device was bought unbranded in US.
Because there are issues with this router, encryption and media streaming devices, I have only restricted the mac addresses with no encryption.
Still don't know about the 169. ip address beacuse doesn't seem to come up as am ISP.

Now then, how wierd is this?
After all these issues and kind of giving up on it as a bad job, I also noticed that out on the road, my GPRS wasn't working either - TomTom couldn't connect to the "plus" traffic service.
I get on the phone to O2 who told me that my phone hadn't been "provisioned". After one false start where they didn't seem to do anything about it, I have just (literally) had them tell me to go to the O2 Operator settings and tell it to update the "O2 UK Post Pay_GPRS" and reboot.
GPRS now works. And magically, so does my WiFi - IP address negotiated and full access to internet and my router's setup page granted. Working like a charm again.
So - seems to me it's an account setting, and nothing to do with either me poor ol' router or me nice new phone.
For completeness, I was occasionally getting the 169 IP address too, so it sounds like we have EXACTLY the same problem - suggest you get onto your service provider ASAP.

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.

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.

Wifi / Browser Problem

Hi,
I'm using:
Roger Captivate
-Serendipity 4.3
-Speedmod
-JK4
I'm having trouble with my interent via wifi.
It connects to my home, mall, etc..
But when it connect to my school wifi, it doesnt work properly.
In-order to connect to the school wifi you have to login with your student number.
This is done by connecting to the school wifi - which it does perfectly.
And then opening a browser would lead to right into the logging screen.
However, instead of going right into the logging screen, it just load the homepage.
And you dont get interenet access until you are logged on.
It seems like the browser doesnt automatic go into the login page.
Also, when I go on the mall wifi, it require you to check an agreement.
But it went to the mall homepage/ agreement page perfectly fine.
Tried with stock browser and dophin mini...
I know the school wifi is working properly because my classmate beside me is using it fine, and I'm on it with my laptop.

Question Please
Was this existing problem before rooting your phone, (STOCK)?

AirDroid won't work w/ ICS Leak?

I can't get AirDroid to connect using ICS leak 213.
I can't even get my phone to respond to a ping from my laptop on the same network, though I can ping my laptop from my phone on the same network.
Any ideas?

It sounds more like a network/router issue than an AirDroid issue, it worked fine for me in .213 and .215 leaks.
Is your phone on a VPN connection? If yes, then it's possible that your phone has multiple IP addresses and AirDroid is showing one which is not accessible from your laptop.
Did you try both connection methods? Via the local IP and via the AirDroid.com wensite?

No VPN connection.
I tried both by local IP and web.airdroid.com, and checked that the local IP is correct from both About>Status and my router.
If I try to connect just through Chrome, I never get anything. If I try to connect by scanning the QR code through my phone, I can sometimes get it to connect initially and bring my to the AirDroid desktop, but I almost always can't access contacts, messages, etc.
I tried port forwarding 8888 for my local IP, but that didn't seem to make any difference.
The strange thing is that my Touchpad works fine with AirDroid. In the past, I've had some odd Wifi issues with both my Droid 4 and my Droid 3, e.g. adding an Exchange account won't complete setup if I'm using wifi on either of those phones (on GB and ICS), but it has worked fine on Android devices without cellular radios (my Touchpad and Archos 101).
It appears like it's a network/router issue, but at the same time appears like it's not.

There could be a clue right here. Do you have a mobile data subscription?
If yes, then perhaps there are some very small WiFi drops which cause Android to try to connect to mobile data instead of WiFi, and the time it spends without the local IP might just be enough to impact AirDroid performance.
You could try the following:
Put the phone in Airplane Mode to disable all wireless connections
Manually enable WiFi - this is possible without disabling Airplane Mode
Now you are on a pure WiFi connection, no mobile data or Bluetooth PAN to interfere. Does that improve AirDroid's behaviour?
Also, if you know how your router works, you can give the Droid 4 a fixed IP address to avoid the IP changing when there is any network hiccup. Most modern routers usually seem to remember which IP they assigned to a device via DHCP anyway (at least for a limited amount of time) but it's worth a shot.

No such luck with the Airplane Mode/Wifi. I outright turning the cell radio off with Phone Info too, still didn't work.
With DD-WRT, my router will keep IPs and MACs associated, so it's not that the IP is changing.
If I reboot the phone, it'll work a little bit initially but eventually stop working and I won't be able to ping it either.
