System freezes when downloading files Using firefox (but I assume the same would happen on IE). I have a desktop computer, but the only option for internet in my house is wireless so I installed a PCMCIA adapter card, and stuck my wireless lan adapter in there. Been using it for about a year now, no problems. But recently I built a new computer, and have these strange glitches every once and a while. If I try and download a large file (game demos, or movies for example), then suddenly I will lose my internet connection, and my computer hangs for about 10-15 seconds. No response at all (including Ctrl-alt-del). The download is cancelled, and my internet connection then comes back on. Any ideas what could be causing this?
