Use the settings we have found to work best in our Networking forum. It's in that forum's tip or sticky at http://forums.cnet.com/5208-7589_102-0.html?forumID=62&threadID=264135&messageID=2584349

As to signal strength, I'm still unsure how to tell owners that the number of bars or percent is not calibrated from machine to machine or such. How would you tell them that? It's a dead end to look too close at that.

As to working here and not there, etc. You are not set up with the settings we have found to work well, be secure and not cause trouble.

Good luck,
Bob
