i have a dell inspiron 8600. maybe about 4 mons ago or so i actually did a fresh re-install of the windows xp home os. this laptop has an internal wireless card which is the Intel 2200 Pro/Wireless. i’m running avg anti-virus and zonealarm pro. windows firewall is disabled. we have comcast hsi with a linksys wrt54g router.
the problem is that my download speed is getting cut short when using wireless. if i plug in via ethernet cable i can pull on average 14.5 mbps dl/ 1.5 mbps upld. but when i connect wireless i hang around 3.5-4.5 mbps dl/ 1.5 mbps upld. which is a dramatic change.
here’s my check list so far:
disabled zonealarm and avg (i know it’s just antivirus but trying anything)
tested this using a mac laptop, and another dell desktop and both are fine
gave my comp static ip
replaced my wireless card with a brand new Intel 2200 Pro/Wireless
…by the way i’m sitting in front of the router during the tests
mulled around the networking settings but couldn’t find anything concrete
updated drivers and also tried various wireless management programs
there may be more but that should be a start.
i’m just stuck guys. i really thought my old wireless card was just broken or stuck in “b” mode or something but it literally didn’t do anything after the replacement. maybe there’s a setting in the bios or something that i’m not familiar with that could cause this? any help would be great. so frustrated.
thx!

speedguide.net has a free tool by the name of tcpoptimizer that will tweak your registry setting for your wireless nic. You can download it here
You might want to try this after verifying all is configured properly on the router side.
