WiFi - Connected but not working - Page 12 - iPhone 3G

Galitw · 05-16-2008, 04:28 PM

I had a problem of too aggressive EDGE, that did not allow me to access the WiFi at home. The result was "unable to access"...
This solution of re-defining the WiFI network did the job!
Thanks a lot!

The .11 is the actual DNS provider, and the .254 is the address of the ADSL modem. On my laptop, the OS will try these two addresses consequently. But in iPhone, it automatically uses the .254 as its default DNS (although it lists the two addresses consequently in the DNS field). It does not even test the .11 after a while since if it uses the .11, I can browse the webpages for sure. That is the reason my wireless on the iPhone connected but I cannot browse any webpages.

I figured out the issue when trying to use my PC as a host that provides Internet access for my iPhone by using the Internet Connection Sharing of Windows Vista.

So, the solution to all of who are having the same issues like me is that to check the DNS server settings carefully. Of course, there may be other reasons. But it would be worth to have an eye on those DNS. Be sure that only ONE DNS address is provided to the iPhone. I think this is to force the iPhone to use that DNS address. Here is my way to do it:
- I have the iPhone connect to the wifi using default DHCP query.
- After that, I change the wifi setting in the iPhone to use the Static mode (DHCP, BootP, and Static modes for each wifi connection, remember?). Then fix the DNS address to a suitable address. The problem is solved. ^.^

Another recommendation from me is that you should try the Internet Connection Sharing feature of Windows first. If the iPhone can connect to the laptop via wireless, and the laptop's wired connection is shared by Internet Connection Sharing (ICS) under Windows Vista (in my case), and if your laptop's Internet is oke, then your iPhone's wifi connection should be ok. When using this method, your laptop's wireless adapter will gain the IP 192.168.0.1 (this is automatically assigned by Windows when using ICS). Your iPhone therefore will get a 192.168.0.x IP when connecting to the laptop in an ad-hoc connection. The gateway and the DNS setting of your iPhone is also 192.168.0.x. Hence, you will see, if your iPhone can browse webpages in this sharing mode, and it cannot browse if connects directly to the router, then the problem should be router setting. DNS, default gateway, etc may be the cause.

Hope this help!
Happy wifi-ing ^.^

I just got the same problem on my ipod touch. ive been connecting to my airport extreme base station for months and now it wont connect. the network appears in the choose network box and i can select it and it gets ticked but i dont have the 3 bars that represent signal strength.
I suspect its a problem with the hardware and will have to be replaced

yea so iam having a problem also, where i connect to the network, but it goes to edge when i go to do something and the wifi symbal doesnt replace the e at all. i tried doing airplane mode and back, doesnt work, i tried to restart both router and phone and no luck, and i cant seem to find the wep hexi or w/e options you guys are talking about, it just shows the network and i go to pick it and it just asks me for password, no where to pick other options. any help would be appreciated.

Came across this thread in my quest to fix my same problem and thought I'd post a fix for those in the same situation...

LINKSYS router users - Install the latest firmware upgrade. I believe the old Linksys firmware was having trouble with the DHCP when connecting certain devices. Upgraded my firmware and was connected in seconds.

May also work for other brands of routers. Firmware upgrade is a good thing to try if you're having difficulty with specific routers.

Hi All, just got my iphone 3g and was having this exact problem....all fixed now. you rock!

ramplay · 07-19-2008, 11:31 PM

short and sweet (lets hope) Go to this web site listed at the bottom of the post and hit get started follow the instructions and you should be set if this is a router issue. you first need to forget your current connection then power off wifi,

Yes, I was having problems also. Kept asking for password and like an idiot I could not figure out what that was...Was on the bottom of the router all along...DOH..
