PCI WLAN route died

My PCI WLAN router, model BLW-04EM had been working fine for over six years. Today, the WLAN transmission suddenly ceased which might be due to failure of the radio transceiver. Actually, this one supported WEP, the key of which can be compromised easily. I have long considered to buy another WLAN router that comes with WPA. This is the right time for replacement.
