I just bought a Toshiba Satellite notebook model M115-3094. I already have a router, a Linksys BEFW11S4. The Linksys is a B router, and the Toshiba has A, B, and G built in. If I connect with no WEP or WPA security it works fine, however if I add WEP or WPA, it will connect first time, but after a few minutes of not using the connection, or after waking the laptop from battery saver mode, the connection is down, and it says I can choose a wireless connection. It then takes several tries with the password, etc. The ConfigFree utility does not seem to help so far. On my laptop, I have an Intel Pro/Wireless 3945ABG Network Connection, and Realtek RTL8139/810x Family Fast Ethernet NIC.
For security my router offers WPA PSK TKIP, WPA Radius TKIP, Radius, and WEP 64 bit/10 hex digits or 128 bit./26 hex digits. The laptop properties box offers WPA PSK TKIP (which is what I'm using), as I don't see the other choice, AES, on my router. The laptop also "offers" Open and Shared WEP, if I'm reading it right, and WPA2, and WPA2-PSK which I don't see on my router.
Any help appreciated, thanks much.
