Yes, it's the wireless one. One computer is linked directly BY WIRE to it, but the other is in another part of the house and it has a wifi card in it. Generally, I have no problems, but sometimes, when I open the Netgear software up, it displays the presence of OTHER networks, with other or same name (NETGEAR; it's the default name and I was too lazy to change it. I think it's a bit of work now, isn't it?) and often on those days, the signal strength at reception computer is very low or not at all.
I wonder, is there a sort of "spurious signal rejection" possible with wireless systems? I'd like to lock out other people's systems from my mine and mine from theirs!
