Hi, First time poster here. Here is my problem. I have a WAG54G v1. I have had it for a year and a half with not much problems. Up until recently I had 3 computers hooked wirelessly and all seemed to work fine. I just added a 4th one to the network, and now the network disconnects. You can't even see it in the view wireless networks page. I have to turn the router on and off to get it to restart. The new computer that was added was a Toshiba with an integrated adaptor. Also, I have been getting on my firewall log: Invalid TCP packet recieved, dropping packet. Could this have something to do with it? Would turning off the firewall help? I have the windows firewall on all the computers, and up until adding this new computer it didn't affect it. I have had the router on it's side to prevent the overheating issue as well. I have read this forum to get my help until now. I just can't seem to figure this one out. Oh, and all the computers are on static IP addresses. Thanks in advance for any help.
