My laptop, running Windows XP Professiona,l was recently infected with malware and was fixed with you guys' help. I installed avast! as my antivirus (I'm loving it) to prevent further infections and tried installing ZoneAlarm to serve as my firewall.
I got an error message during the ZoneAlarm installation and wasn't able to complete it. I decided to uninstall ZoneAlarm and use the default Windows Firewall instead. I later read that ZoneAlarm is not really compatible with avast! and that many people dislike it, so, I was happy uninstalling it.
Now, the problem is that after the forementioned incident my wireless internet sometimes seems to slow down to a crawl. Curiously enough, when I move my cursor over to my Wireless Network Connection icon on my taskbar, it shows a Speed of 54.0 Mbps, an Excellent Signal Strength, and a Connected Status; also, when I double click the icon, it shows 5 bars, however, when I click on "View Wireless Networks" the router I'm connected to shows only a one bar connection.
At first, I thought Windows Firewall might be causing the problem, but, I turned it off, and the problem is still there. After reading nightmare stories about ZoneAlarm, I'm worried that the problem originates from the failed installation attempt and that removing the program did not change the fact that my connection was already ruined. This is pure speculation though.
My router is a 2wire 2701hg-b
and my computer connects to it with a D-Link AirPlus DWL-G630 wireless card.
I brought my laptop over to the room where the router is, and I still got only one bar.
I'm pretty sure that before, the signal strength shown by double clicking the wireless icon and the signal strength shown under "View Wireless Networks" matched. This is the first time I see two different signal strengths.
Any help is much appreciated.
