[TriLUG] Weird WiFi router behavior

Tue Jul 26 20:10:01 EDT 2016

Make sure that your router is using WPA2 encryption. I don't think Apple
likes the old WEP encryption. They might not even like non-2 WPA. Make sure
your router is configured for WPA2-PSK / AES (not TKIP).

If you change your router's encryption and/or passphrase, then change the
SSID to something different, too. Otherwise some devices might be confused
when trying to connect. So if your current SSID is BOTHNET then your new
one could be BOTHNET2, or BOTH2NET, or BOTHNETTOO, or something.

Make sure your router is configured to have the LAN on a different subnet
than the IP address that it's getting from the modem. Weird, weird stuff
happens when the IP address that the modem gives the router is within the
range of the IP addresses that the router gives out on the LAN.
