Help Wi-Fi problem

JohnDoe · Apr 7, 2010

I have a problem with my Wi-Fi connection.

I turn on Wi-Fi, go to Wi-Fi settings and under the list of found networks is my home wireless. When I try to connect to it, it goes as far as "Obtaining IP adress" and after that it fails.

I thought this was because I was using GalaxHero, but now I went to using Mustymod's 2.0 and the problem is still there.

Any ideas how to fix this?

are you sure that your ap is acting as a DHCP server?

DaSchmarotzer · Apr 7, 2010

Well, maybe someone else who has encountered this issue can help you better than I can, but some of these general tips might help you.

- Set up your router in G mode only.
- Lower the beacon interval from 100 to something like 40

But considering your problem, it's probably an issue with DHCP, make sure it's turned on in your router's settings. It might also be an issue with a Firewall or your network only accepting fixed IPs, but we're probably gonna need more information if no one knows what causes this problem. On the other hand, may be your device is set to use a static IP that is not in the accepted range by router?

Hope any of that helped. If it does not, you can try disabling your network encryption security (WEP, WPA) and see if it works with an open network.

All I know is that it worked before, and now it doesn't.
I didn't do anything with the router in the mean time.

while it was working which firmware were you using?

DaSchmarotzer · Apr 7, 2010

Did the problem first start when you connected elsewhere? Like a network in an hotel, meeting, or something?

If so, you might want to remove that network from your saved networks.

You have to pinpoint what caused it to stop, but that's far from easy.

i don't know the exact words to tell but sometimes "ap/routers dhcp pool becomes full" and it wont assignes any more ips .

informale · Apr 7, 2010

How can it become full? Surely you don't keep 254 wifi devices at home )

I suppose rebooting router should reset/empty that pool.

Anyway, try manually assigning IP in the phone settings - at least to see if it connects to your AP. Also you should try enabling IP assignation according to MAC address in the router settings. If you are struggling, tell us your exact router model. Perhaps someone (may be me

). Will advice you how to do it on your router.

your router is using wireless n protocol and not mixed or G

set it to G only and see if it works

JohnDoe · Apr 7, 2010

I first connected with the stock firmware, then with GalaxHero and it worked fine on both till it sudennly decided to stop working.

Now I'm on Mustymod 2.0 and it still won't connect.

The list is empty except for my home wireless.

Router is D-Link DSL2640-R

Rastaman-FB · Apr 7, 2010

i have the same router and by default its mixed mode, please change it to g only and test

JohnDoe · Apr 7, 2010

I don't think I can cause of the ISP's here in Croatia using stristly one and I think my ISP is B, not G so my internet wouldn't work.

JohnDoe · Apr 7, 2010

Sorry for double post but it seems I have solved this problem.

My router firewall was on and when I disabled it I was able to connect with my phone to the internet.

DaSchmarotzer · Apr 7, 2010

Didn't I say that posts ago? :thinking:

Oh well, I guess you didn't overlook what I said and it all worked out for the best.

@Informale: sometimes some ISP restricts DHCP pool to 6-12-24-bla bla devices.

aren't you in control of your own router at home?

That depends on WHO provided the router. For example, my broadband connection at home, the router was provided by my ISP, and I'm not supposed to go fiddling around with it. Then, once, when I had a problem, their tech help came by and needed to log into the router. I just stood behind his back and memorized the password he used. Now, I go changing the settings as I need and only change them back to default if I have a complaint or if their tech is coming by again.

they always give you that nonsense
what dhcp ranges you have on your internal network or what wireless signal your device is programmed to use is not up to them as it does not affect the isp
the only reason they dictate it is so that its easier for them to fix if you raise a support call

True, too true. Then again, if you are a geek, such 'restrictions' shouldn't matter.

The problem is back...

I rechecked if my router firewall is still off and it is, but the phone fails at obtaining ip adress.

Please help guys!

they use this restrictions cause they don't want a whole building using same internet account. because of this we had bought a wireless ap and used it as the dhcp server

that looks nonsense but its commercialism.

change the router to G only please

JohnDoe · Apr 10, 2010

Did that and now I am connected to the router but no internet connection... :thinking:

Rastaman-FB · Apr 10, 2010

thats odd that it cannot get internet if you are connected. the only time ive seen this is when the router is misbehaving
my 2740b is very flaky at times and needs a reboot.
you may need to reboot it and reconnect
use wpa/wpa2 and not wep
put the try different wireless channels, i find 1 and 11 work best
