Help with internet sharing/tethering? (guess I'm more noob than I thought)

Posted by: erikk

OK so I thought I was halfway intelligent about all this but apparently not. I can't seem to get my internet sharing to allow me to tether on my new Tilt. I had it working fine on my Sprint Mogul so I know theoretically how to do it. I have the stock AT&T ROM (allowed customizations; just lazy about figuring out what I'd need of the customizations so I live with the bloat).

I created a shortcut for IntShrUI.exe in my \windows\start menu\programs folder to start the internet shar. I start Internet sharing and select USB and AT&T ISP GPRS (or MEdia Net; same result). It says connected and doesn't give me any errors but I can't seem to connect to anything from my PC or even ping anything. I'm using a Windows Vista PC.

I was originally on "PDA Personal Max UNL + 1500 Messages" but I couldn't seem to connect to ISP.CINGULAR and I thought maybe that's why I couldn't tether (and I thought it'd probably prevent me from connecting to my corporate VPN). So I called in and the tech guy said that plan isn't provisioned for ISP.CINGULAR so he switched me to the "older" (his words) PDACnctUntlAdd which is the same price and includes ISP.CINGULAR but not 1500 messages. In hindsight I'm guessing that's not my problem and I'll prob go back to PDA Personal Max with the 1500 messages once I figure out the tethering and assuming it allows me to VPN.

My settings are:
AT&T ISP GPRS
Modem:
MEdia Net
Modem:
I've tried to do it with the proxy disabled and with it enabled with the same result.

So what can I be doing wrong? I'm sure it's something supremely stupid but I can't for the life of me figure out what I'm doing wrong.

Any help greatly appreciated and let me know if there's anything else you'd need to know to get this working.

If it matters I have the following installed:

And of course it was a stupid thing not to check but something made me try connecting to an IP address and not a URL and BAM! it worked. So I guess I have a DNS problem and not a connection problem.

So now, anyone have an idea why the laptop can't resolve DNS but the Tilt can? Should I manually set free public DNS servers on the Tilt? Or on the laptop?

You should be able to set DNS settings for the bluetooth modem. Are you using a Mac or PC? I don't know how it works on a PC, but this page will give you the right DNS servers to use: http://www.taniwha.org.uk/gprs.html

I'm sorry I should have been more clear. I know how to change the DNS settings for the modem and in fact since my note I set them to free, fast public DNS servers (208.67.222.222, 208.67.220.220) and it works fine. I use them on the phone now too since I think they resolve faster than the AT&T ones.

At this point the question is why can't my laptop resolve DNS through the phone with the default settings like so many other people can?
