Wireless Keeps Disconnecting

OKAY - PLEASE HELP ME!!!!!!!!!

I have been pulling my hair trying to figure out why my Dell Inspiron 1150 keeps disconnecting from the Internet while I am at home. Here is a rundown of what I am encountering:

- The Dell has a built-in Dell Wireless WLAN 1350 WLAN Mini-PCI Card with the newest drivers (just updated today).
- My router is a NetGearWGR614v3 with the newest firmware (just updated yesterday).
- I have tried factory resetting the router and this has not helped.
- I am using WEP.
- I have another Compaq laptop and it never disconnects or crashes the router.
- Any time I go to a busy webpage (like buy.com) - something crashes my router. This only happens with busy webpages with lots of graphics, etc. - which is totally weird and makes no sense to me - but, it does not happen on light pages like Google or with searches, etc. Essentially when this happens I HAVE to unplug and plug back in the router to get it to re-set and re-connect. There seems to be some type of conflict with my laptop and the router, but I have no clue what. This never "used" to happen and just started about a month ago and I have not added any new programs or changed any settings that I can recall. I have had the router for over 2 years with no issues until now with no setting changes.
- I have tried disabling Windows Zero Config and I have tried enabling it - nothing works.

One more note - if I connect directly to the wireless router with a ethernet cable it works fine and I don't have any issues.

PLEASE HELP ME because this is driving me absolutely MAD! :) Thanks, in advance!
