I have learned that wireless access points don’t die — they degrade. Both at school and at home, WAPs become flaky in their old age, so that the wireless network exhibits problems easy to attribute to other issues such as channel conflict. I just upgraded our wireless access point at home after weeks of “a wireless error occurred” messages from our Macs. Thankfully, the new one has made our access point happier again, even though the marketing “RangePlus” gimmick still does not allow wireless to reach all the way to the bedroom (must be a PC thing). Our new AP: Linksys WRT100. The old, which served us well for years: Netgear WGT624. I also went a step further with wireless security this time, using WPA instead of WEP, locking down admin access to wired computers only, and only allowing known MACs online. I wonder whether manufacturers are actually pushing people away from WEP, since I couldn’t quite get how to correctly configure encrypted WEP keys. If we ever have a 802.11n device in the house, this device is apparently compatible.
