I have tried some other options that seem to allow my laptop to log into my network most of the time. Router resets have dropped & mainly only necessary if my shared directory cannot be accessed from my laptop. Here is what I am using now: Router Wireless - Enable auto channel scan, Super G w/o Turbo, Enable Extended Range mode, WPA2 security, Cipher AES Personal with a passphrase. Router Network - Enable DNS relay, enable DNS server, Added main & laptop to DHCP reservation. On laptop - added IP address (the one assigned by the router DHCP), gateway and DNS server address to Internet Protocol (TCP/IP), Use IP address, Use DNS server and used the adapter configuration utility (AR5005G on a Toshiba laptop) to include my network name, AES and passphrase rather than using windows to set up the connection.
Someone else more knowledgeable than me can probably improve on this setup, but it's working for me 99% of the time, so I am happy. I haven't had to reset the router for several weeks - just when I need the shared directory & it is usually available 99% of the time.
