Connection Problems

I recently upgraded to 7 from Vista, and ever since I've had internet connection problems nonstop. My system specs are:

System Manufacturer/Model Number: HP-Pavilion/KT372AA-A2L a6518f
OS: Windows 7 Home Premuim (student upgrade from Vista Home Premuim)
CPU: AMD Athlon(tm) 64 X2 Dual Core Processor 5400+, 2800 Mhz
Motherboard: Seriously, I looked for any kind of label and can't find it.
Memory: 3.00 GB Ram
Graphics Card: NVIDIA GeForce 9600 GT
Sound Card: Realtek High Definition Audio
Monitor(s) Displays: Samsung SyncMater 920 Nx
Screen Resolution: 1280 x 1024
Hard Drives: Drive C, Local Fixed Disk 263.94 GB free of 455.43 GB total, Samsung

Right now we have one router connected to the modem (ISP is Shaw), and another connected to it that is piggybacking. Anytime I attempt a wired connection into the first router, I'm automatically connected to the piggybacked one, and can't get an internet connection. So I tried using a wireless connection with my Trendnet USB adapter TEW-424UB (CA) (which I have used problem-free on Vista for over a year), and I can get a connection on the second router, but only for a few minutes at a time before it drops. Sometimes it drops every five minutes, and others it can go for fifteen minutes or so before it drops. If I try to connect wirelessly to the first router (this is the router that I've been using for the past year), it shows that it's connected, but I can't access the internet.

Please help.

This should be relatively easy to fix. Find out all the information on the router you're connecting to first. Get the manual, find out it's config ip address...etc...

If you know that, you're ahead of the game already.

Setup a static ip address for the network card(s) in Network and Sharing center when you click on Local Area Connection.

You want the IPv4 line. Double click that. If you need further help, let me know. No problem.

(Check task manager for mdnsresponder.exe. If it's there, definitely let me know.)

I ended up purchasing a wireless N PCI card and we got rid of one of the routers. I haven't had any network problems since. Please close this topic. :)
