Solved default gateway issue

[drmax]

I can add the default gateway in the network adaptor IPv4, but when I restart my pc, it goes away. I can't keep a connection to the net, without getting this default gateway in place, or so I've read. DHCP is enabled.
What is happening, I have a AT&T modem and for some reason, after my PC build, I get kicked of the net, within a few minutes. I've read I had to stick in the default gateway. (which I know what that is) When I do stick it in, it's there but grayed out, because the "obtain IP addy auto" is ck'd. If I unck and try to use the "use this IP addy", then I don't know what that is. Something is screwed up. It was working fine a few wks ago. Please advise.

If the obtain the IP address is checked for auto the rest of it should automatically populate. What is your gateway? Do you have a router that you connect to or are just straight plugging into the modem?

My modem is speedstream 5100. I'm also using a wrt54gs lnksys router. The ip addy and default gateway I was getting, was from the lnksys. i unplugged router and went directly into modem and abviously got a different set of number. Apparently, I need to see something different in my windows 7, to let the lnksys operate normally, or do something with the router. Unsure at this point. With it all hooked up, it works for maybe 1 minute, then I get the yellow mark in int. connection bottom right corner. The built-in "troubleshooter" can not fix this one.

Hmm, see if this might help you. The Speedstream 5100B modem and SBC/Yahoo DSL

Hello,

Is this a wired or wireless connection issue?

Pls. provide an ipconfig /all output for us while your computer is connected to your router:
Click on Start => in run or search box type cmd, press enter. From the command prompt (black screen), Copy and Paste these ipconfig /all >c:\ipconfig.txt . Please attach the .txt file to be found in your Local Disk 'C' on your next post.

Wanted to clerify...I have 2 other pc's working off this router, wirelessly. It's just my new pc that wired, rather the main tower with W7, that is having the issues.

What type of Anti Virus or Security Softwar do you have installed?

 

[drmax]

antivirus

Avast

 

[2xg]

Let's uninstall your Avast for now, pls use this Utility:
avast! Uninstall Utility
Then replace it with MSE for protection:
Microsoft Security Essentials - Free antivirus software for your Windows PC - Your Digital Life New Zealand

Avast

Pls post another update of your progress.

 

[drmax]

ok, i'll undo avast for troubleshooting purposes. this was all working before, with avast, but will give this a try. will let you know what happens. thx

 

[drmax]

without installing anything else, just removed avast. attached is my ipconfig afterwards. please advise. if has changed, i guess i'll use the other antivirus.
thank you kindly. ps..dunno why this would all the sudden start doing this, as it had worked in the past. strange.
also, would it have something to do with me having to reset the router, since the signal is going through linksys 1st, then to pc? you see, the router used to me hooked up through my other tower, which is XP. hope my info helps...
