More info?)
I am using a slightly older DLink DI514 Wirelss Router and a dlink PCI card
in his PC. The 802 authentication is off but I have WEP (w/keys) turned on.
I tried changing the preamble to short and the TX and Baic rates to 1-2Mbps.
but that didnt fix it either? The distance is about 50 feet or so (through
different floors) but the signal varies greatly from Excellent to Good or
Low. This is really strange. Thanks!
