Did you read the discussion about Zone Alarm in this forum?
I have an IBM thinkpad with an internal wireless card. I use to have great download speeds until I used went over to a friends house and used his wireless network. My download speeds have dropped from 2 mbps to 60 kbps. I tried the following:
I removed his network from my preferred networks
Turned of windows XP's firewall
Ran Ad-aware to remove any spyware programs
Ran virus scan
Can someone please help as these speeds are unbearable
