My fixed wireless system used to run at about 1024kbps, but about a month ago, it started slowing down. I started getting speeds of 512kbps and lower. Now, I am lucky to even get 200kbps. My download speeds used to run about 120 KB/sec. Now they run at about 15-20 KB/sec. I also get frequent disconnects lately, so much its hard to even have an AIM conversation. I've contacted my ISP and they said they could find nothing wrong. So I am wondering what else could be causing this problem. I have run spyware checks using Adaware, Spybot, etc, and they didn't find anything.
