Vista - Intermittent connection like you never saw before

My Network and sharing Center is an action movie. I have two days with that windows maximixed, I turn on the computer and everything is great for no more than 2 minutes, then the action begin, the red X appears between the Network and Internet Icons, I lose conectivity from all, it came back after 15 secs average, then after one minute 6 tops is down again. Sometimes appears a warning triangle sign between my pc and the network icon then I get "limited conectivity" and it fixes by itself after 15 to 20 secs. Is like that all day.

I'm not a tech saavy but I swear I read every related post I found and I tried every single step to fix this and nothing.

Please help. Tell me what you need I'll give it to you I'm gonna be the 1 minute I have internet refreshing this post to provide you all the stuff you request to help me solve this damm thing

There's not much in my network. My computer and a laptop right now.
Router I'm using: Cisco Linksys WRT54G2

To Zig Zag.
I deactivate IPv6, I'm not using nic's I've tried with static Ip or dinamic (through DHCP) I tried without the router (my comp plugged directly to the ADSL Modem), I've tried through Ethernet (wired) Wireless, usb. I change values in the registry and add some other, I've resetted the sockets..... and to my disgrace the last thing I've tried leave me without computer I've change the tcpip.sys archive for one that I downloaded from a page following its directions and now my comp won't work.

Try a restore point to fix the tcpip.sys archive problem. Unistall the drivers for ur nic card, then let windows reinstall it and tell it to search the web for driver's. Hope you have a recent restore point before u did that, so u can just do a quick roll back and be golden!
