It has notes about router firmware, ssid, encryption that may help but let's get that out of the way first.
System: I am running Windows XP on a two-year-old IBM T42 with Norton Internet Security activated August 2007. I bought a D-Link RangeBooster G (also in August 2007, before installing Norton) and disabled the internal wireless adapter because I couldn't get a connection with the internal adapter. (The internal adapter was: Intel(R) PRO/Wireless 2200BG Network Connection; one day the driver went bad and after many attempts to install a new driver from the Lenovo website I still couldn't get it to work). I disabled all the firewalls I can find as well as most of the other functions of Norton Internet Security.
Problem: The internet connection will run for a short period of time, then I lose the connection for about 30 seconds - then it comes back again. I lose the connection when:
1) I plug something into the USB port, such as a flash drive or a web cam,
2) about 70% of the time when I type a web address (any address, such as www.yahoo.com) and press enter.
3) about 70% of the time when I click or move within a web address (searching, for ex.), especially when I press Enter to start a search within a page
4) occasionally even when I'm not doing anything at all.
Also, on two occasions I got a blue screen of death when I was using MSN instant messenger and trying to share web-cams (friend views mine and I view the friend's).
One more thing, whenever I shut down the machine I get an error message referring to the D-link wireless connection manager being nonresponsive.
Any ideas of what I should do?? It's extremely frustrating and I feel like the answer is right at my fingertips but I can't figure it out.... Thanks all!!
