As I noted in my original post, this was for my parents, who were using a Pacific Bell/SBC/AT&T-provided combo DSL Gateway/WiFi-G Router, with encryption limited to WEP. Even though the bridge supports up to WPA-2, the DSL/Router was the limiting factor, and my parents have no intention of changing that. They don't do anything critical or financial-related on their computers, so the danger of hackers is low. Also, the usable range of the DSL/Router isn't all that great, which further limits someone from hacking in.
But security is always something to keep in mind.
Understand, wasn't really directed at you or anyone in general. But you know for those that I know who live in apartment complexes, it's not hacking a computer but using the network for their benefit that is illegal, which doesn't necessarily compromise the computer you know. And if someone was more technically able, they could adjust the power of the router as I have done. I have it set on the lowest and I can access it anywhere in this duplex. I haven't done a walk outside yet to test it's range, but sitting on the the front corner by the computers, it probably has a good range to the street curb.
That's one thing that I was reading about the Linksys adapter, the WPS security feature. There are supposedly like 4 different levels with WPS, one being the highest, which would require the clients and hosts to be the same manufacturer; to take advantage of that highest WPS level that is. But merely in general for anyone that would read or search for this, they'd have something to reference to keep in mind. As I stated, I was only searching for more information amongst this forum for my model number and this thread came up.
