This has been a long ongoing problem. I'm running Windows XP,SP3. My internet access is an AT&T 313u Momentum 4G air card. It connects to the internet fine and has a good signal. On many of my attempts to access a website, I get the "Internet Explorer cannot display the webpage". I've updated firmware, reset drivers, and I've had several discussions with AT&T tech. people. They always want me to unplug the modem(air card), uninstall the modem in Device Manager, then reboot my computer and plug the modem back in. This may or may not help, sometimes it seems to, but just as likely it doesn't. If it seems to help, it's not very long(minutes), until the webpages are timing out again. I'm sure tower congestion isn't the issue, I'm up at 1 or 2 am. sometimes and still have the same problem. I've run ipconfig/all, but the DHCP server and DNS servers addresses can't be pinged. I don't know how any names are being resolved to an IP address, and usually they don't. If any of this makes sense and someone wants to help, I sure would appreciate it. Thanks in advance, Roy S.

Show us the output of ipconfig /all please.

Click on Start then Run or press Window key (next to left Ctrl key) +R and paste the following into the Run box, exactly as shown, including double quotes:

cmd /c "ipconfig /all > postme.txt & ping yahoo.com >> postme.txt & notepad postme.txt & del postme.txt"

and press ENTER.

A file will open in Notepad. Please copy and paste the contents here. Close the Notepad window and the file will be deleted and the Command Prompt window will also close.

If you don't have a Run selection off the Start menu, see here: Enable Run Command on Windows 7 or Vista Start Menu, or just press Windows Key (next to the left Ctrl key) + R.

This will be the forth time I've tried this. My internet connection keeps timing out. Maybe I'll get it right in next post.

Never seen ipconfig output from a computer connected via 4G cell network. Numbers are strange, even the DNS, but they work as seen by the ping Google response.

I'd say this is probably a problem with your Momentum 4G air card. Any way you can connect via normal wireless or wired Ethernet to do some testing?

I this a laptop or Desktop? If laptop, take it to a library or coffee shop to test?????

If Desktop, take to a friends house to test?

[chaknik]

Thanks for the input. The DHCP and DNS is confusing to me also, but somehow it works(part of the time). This is a desktop and no one I know has wired ethernet. We live in a very rural area. Thanks again and if you have any more thoughts about this, please throw them at me.

Can you borrow a friends 4G card to try?

Trying to narrow down the cause of the problem and that would help a lot. It will tell you if your 4G card is the problem or not.

[chaknik]

My brother has the same air card, I'll borrow his and give it a run around the block. I'll post back with results.

I found a Microsoft 'FixIt50199' that changes some TCPIP paramaters. I downloaded the FixIt and ran it, then it had me to reboot my computer. After that, I was able to browse the internet normally. It looks like AT&T's software for the air card puts some funky values in that cause the problem. I've got the most up to date version of their Communication Manager and firmware in the air card. I guess AT&T has dropped the ball again. As long as the FixIt works, I'll be fine. Thanks for your help and the FixIt may benefit someone else. I consider this thread closed.

[Ztruker]

Good going. What pointed you to that Fixit?

[chaknik]

I was able to do some searching about those DHCP and DNS addresses, how to flush the DNS resolver cache and re-register and I came across a link to Microsoft FixIts. One of them, the 50199, was suppose to set TCPIP parameters, so I gave it a try. The Microsoft website listed all sorts of technical stuff that the FixIt changes, but it's too much for me to comprehend. I just run the FixIt and browse away. Unrelated to that issue, I have a problem with my home network setup. Now I'll have to change gears in my head to look at this one.
