[Slavi]

I have a internet connection problem , my pc is connencted to the interneted via ethernet to the main box which is fiber optic to the internet center. It has been working perfectly for around 6 months and now apparntly it started creating some problems. Usually i have internet for like 10-20 minutes sometimes an hour then it dissapears and it wont come back UNLESS  I RESTART PC . Even if i plug cable back in or out only pc restart will help. Since this problem has occured i wasn't cabaple of finishing one game. Oh and i have 2 pcs at home if that might be the issue but im not sure because i had one switched off for a week to see and problem was still thier.The local area connenction is still on sending packets but no recieiving once its goes off but it still is connection.

Help me out please , tell me if thier is any way i can fix it and what the problem is .

Something propably changed in your router configuration.

When you got internet working on your comp, start a command prompt and type

ipconfig /all

After you lose your connection, do it again and check your IP.

It may be come DHCP problem (if you're letting your router set your computers IP). You can try de-activating your DHCP option on your router, and set your computer's IP manually (to something like 192.168.1.2, or 192.168.0.10.. depending on your router's own IP inside your local network)

You can also check your router logs, if you can access one.

If this doesnt help, then warm up some good antivirus and learn using HiJackthis to clean your system.
