The massive wifi problem that many experience

When I turn on my phone at work, the wireless connection (open unsecured) connects and works for a few minutes. After some time, it disconnects and without rebooting my phone, I cannot establish a wlan connection.
This is oly the case at work. At home it works flawlessly, but it is another network kind.
Anyone found a solution to this problem? I saw a lot of threads about this but no good answers.
I am using duttys v3.

Not sure. Perhaps there is some sort of time out on your work network for inactive devices, or dhcp ip releases or something weird and "networky" like that?
Or perhaps your phone is going into a power save mode if you are not using it?
Just general ideas, I don't have this particular problem

I dont think many people have this issue! you must not have a setting correct, try downloading KaiserTweak and adjusting the timeout and also take a look at the routers settings I find it strange that a business would have an open network for security issues

I work at the university, and the network is unsecure. You have to enter login and pass at a webpage to gain access.
I cannot reconnect at all once ive been disconnected. So it should have anything to do with kaisertweak or timeouts.
I have tried every setting and combination. I have tried to select work/internet settings. Ive tried to tell the phone its a hidden network / not hidden network. I have tried to use power save / performance mode. Ive tried to turn off 3g, bluetooth, phone (everything basically).
When I tap connect, it says connecting and then it immediately goes to "active" and tries to connect to another network (which I dont have access to).

I have worked out the problem.. first if its a WPA enterprise connection, make sure its set to WORK and not INTERNET setting. it will work. my only works with schaps versions not duttys

on my old pda (Acer N50 premium) I had the same problem with my unis network... it would only work (if at all) for a few minutes then nada... but at home it was absolutely fine, quick stayed on and totally responsive... I wonder if it has something to do with the rubbish way unis run their IT...?

Wasted thread
Many do not have this issue.
According to what's being said here by the indiviuals with issues, you're having problems connecting to a certain network...not all networks.
If it were all networks; your device, settings, equipment or rom would be the common denomenator. Since it's one network, it's that network.
Just because a network is or appears to be available, that doesn't mean that you can connect to it.

no, it could be the phone software. Lets says that a string is added to the registry if the network you are connected to disconnects you; a string that makes the phone cancel connections to the network. And lets assume that the network disconnected you because there is a hidden firewall in the phone software that blocks ping requests, thus making the network believe that the connection is lost and thus disconnecting you. Then we have a moment 22, which is basically something wrong with the phone.
As some readers already pointed out in this "wasted thread", when changing the rom (in one case) or when changing settings from "internet" to "work" (in the second case) there is a great possibility that this problem in fact has to do with phone software and not network.
In my case, it just happens to be neither of the mentioned solutions or any solution that I have found in other threads.

One thing you may want to check is that your wifi is set to max performance. The issue may also be that there is a DNS cache issue, in most cases it can be resolved by manually reconfiguring the connection.
I have been successful in configuring my phone's WLAN to connect to everything from open APS's, WEP, WPA, RADIUS and AP's with proxy redirects, so I can tell you that as with most cases, it's human error.

I have tried max performance.
How do I resolve a dns cache issue? Manually reconfiguring the network did not help (only thing that helps is a reboot).

Wifi Internet

Hey guys, i got my kaiser a couple of days ago. Its a brilliant machine and i love using internet on it using my wifi connection at home. Suddenly it has stopped browsing the internet. It connects to wifi alright, show good strength signal and everything but when i enter a web address it takes ages to respond and in the end gives the error 'check name and try again.' what's wrong with it...?
i'd appreciate if some could help.
P.S. i have done countless soft resets and a hard reset as well.
cheers

I've had problems like that before. By any chance is your router named something like Linksys or default? I'm wondering if it's connecting but not using the correct profile. I'm not sure about the phones but on a computer you can connect to wifi that is wep enabled without a wep key. You can't get any data from the router but it shows your connected.
Also have you tried another access point to rule out your router?

Don't you have to go to wifi settings and change it from BEST PERFORMANCE to BEST BATTERY or is it the other way around?

No, i haven't tried any other AP, its my home network and i have only one router. Its quite an old one but i am sure its not from linksys. Last time i successfuly used wifi internet on my kaiser was a few hours ago before i installed a remote desktop access program on my kaiser. I have uninstalled it now but the problem remains.

The phone might have profiles based on the name of the router, so if you have a common name and it picks another one up of that name, it could cause this sort of problem.

So what do i need to change, the name of the router or the profile on the kaiser, by the way , where is the profile on the pocket pc ?
P.S. its Belkin and the called WLAN.

go into the com manager and hit settings, then wireless lan. You might want to look around in there to see if you can remove the profile.

Hi again, you wouldn't believe what i am about to tell you. The problem gets solved like magic just with a couple of clicks. In your power settings for the wireless network, change it from best battery life to best performance and voila! it starts working. The moment you change it back to best battery life, it dies out. I have tested it time and again and use another utility called 'vxutil' to use different commands like ping and see information like default gateways and DNS and DHCP but everything was alright.
P.S. this will only work if the network settings are correct ALREADY!
Thanks for the help guys!

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.

Issues with new TWC modem/router

Hi all, while thinking that faster internet would be a good thing, it seems that I have managed to break chromecast compatibility with my network. Previously I had a Netgear router that worked perfectly, but when we got an upgrade to TWC's new "Extreme Internet" they installed a new WiFi router/modem hybrid that I cannot seem to connect to. I get the message that it is connected to the network but not the internet. Ap isolation. Is disabled, but I cannot find the plug and play feature anywhere in the network settings. Has anyone found a work around?

If you can give us the exact make and model we might be able to help more.
BTW, TWC changed their policy a few years back and now allow approved customer-owned modems which will save you the modem rental. They used to not charge for the modem rental but also not let you use your own. Installed a Motorola SB6141 for my relative and it's been working great with the Netgear WNDR3700 I put there.
No Chromecast yet because I haven't been by to visit...

You could always use your own modem with twc, just that most people did not know that. Like previously mentioned, more details are needed in order to further assist you. Make and model(tg862g, ddw3611, dvw32011b???). More than likely you just need to call and talk with level 3 tech support. I personally used my own router behind the modem because I do a bit more than normal with my router.

I went through Hell on Christmas Eve with Time Warner....
They have a new Modem/Router they are using....When connected to a personal Router it does a double Nat translation which really doesn't work at all.
Your lucky if you even get Internet access on a Computer with it.
Check your router and see what IP address it has under internet connection. It should not be 192.168.0.x
If it is not an outside IP you need to call support and tell them you need your Router to breach the Modem and have them shut off all ROUTER capability on their Device so that all it does is pass a public IP to whatever is connected to it.
If you get your phone service from Time Warner as well better call on a Cell Phone because they will drop the phone call the second they mess with their Modem/Router and you will suffer through Groundhog day explaining it to the next guy from scratch!

Well guys I solved my own problem in a way. I disabled the wireless broadcast from the TWC Arris router and just connected my old NetGear ( old as in 2 months old) and it seems to work perfectly now. And the installer said, " You won't need to use your old one because this box is like commercial grade bro."
Sent from my SAMSUNG-SGH-I317 using Tapatalk

Glad to hear. The wireless modem you have is indeed a great modem and you could use that alone but it is easier to just use your own. The installer more than likely wasn't on the up and up about the more technical aspects of the modem. You can't knock him for that part as the techs are not trained on a lot of the extra features of the modem. I only know this because I may or may not work for the company(need to keep work out of forums).
