Router problem

[Nooboras]

Hello ,

I am new in the community and i know almost nothing about networking but i have the following problem (i will explain it as good as i can).

While i am connected on the Internet (all the lights on my Linksys WAG200G are on) the connectivity stops (the same lights on the router are still on but i have no internet access) and i can no longer open my router configuration site unless i unplug it and plug it again.

This is what my computer consists of (i am using the on-board netword card) :

Operating System
Microsoft Windows 7 Ultimate 64-bit SP1
CPU
Intel Core i5 2500K @ 3.30GHz
Sandy Bridge 32nm Technology
RAM
8,00 GB Dual-Channel DDR3 @ 657MHz (9-9-9-24)
Motherboard
ASRock Z77 Extreme4 (CPUSocket)
Graphics
SyncMaster (1920x1080@59Hz)
LG TV (1360x768@60Hz)
1024MB GeForce GTS 250 (Gigabyte)
Hard Drives
932GB Western Digital WDC WD1001FALS-00J7B0 ATA Device (SATA)
932GB Western Digital WDC WD1001FALS-00J7B0 ATA Device (SATA)
Optical Drives
TSSTcorp CDDVDW SH-222BB ATA Device
Audio
Realtek High Definition Audio

and this is the version of my router firmware: Firmware Version: 1.01.09-openwag200-13
What might be causing this problem and what can i do to fix it?

Thanks in advance for your replies
