Problem with Netgear WGR614v6 dropping internet connection

Hi,

I have recently sent up a wireless network at home and am experiencing
problems staying connected to the internet. I have an acer travelmate
laptop running Win2K connecting via a netgear WG111v2 Wireless USB
Adapter to a netgear WGR614v6 router. My problem is that I can detect
and connect to the wireless network no problem (signal very good),
however as soon as I connect the wireless status light starts going
mental - blinking like crazy - then, after about 3 or 4 minutes my
internet connection gets dropped. I have tried connecting to the
router via an ethernet cable, but the same thing happens (this time the
LAN port status light blinks like crazy).

My boyfriend can connect to the wireless network with no problem (when
I am not trying, if I am connected it drops his internet connection
too). He can even successfully surf the internet using my netgear USB
adapter; he is using a dell notebook running winXP. I don't think the
USB adapter is at fault as I was able to connect to a different
wireless network a few days ago and stay on for hours without problem.
This also means my laptop does have the ability to connect to a
wireless network. The internet connection/broadband modem also doesn't
seem to be at fault as I can plug directly to the modem and surf the
internet without problems.

I assume the netgear router doesn't like something about my laptop (or
vice versa), can anyone suggest what this may be and any fixes?? My
limited network knowledge means I've run out of places to look.

Thanks for your help.

Nicola
