I use a Mac Book Pro as my main computer, as I travel around a fair bit. Because it’s a laptop, I take advantage of the wireless at my office and my home. I use WPA at my home on a Netgear ProSafe WiFi router, and everything was peachy for a month or so. Then when I spent a week at a remote location, using their Siemens WiFi router in a closed WEP network, I started to get a lot of “Connection Timeout” errors from the airport connection. Additionally, the MBP seemed to refuse to reconnect to the closed network every time I wake it up – I would have to re-enter all those settings. Now, I’m running 10.5.2 (latest OS), so I can’t update any further! Thinking it was just a compatability problem with the MBP / Siemens equipment, I thought it would be all good when I returned home. Not so – Connection Timeouts again. It got to the point where I was unable to connect to the WiFi at all.

The solution? Change the channel of the WiFi on the router. I fixed it to channel 10 and it works fine now. It must have something to do with the way the MBP deals with interference.
