I ordered one of those Asus WL-320Eg gadgets from, I suspect, the same fellow you got yours. You mention you are using it as a "client" and that you don't mind questions. So I have a couple, with, first, a warning that I know VERY little about all this.
I have a VL-6 standard system. I am using a belkin n wireless router, connected to a, I believe, at&t dsl modem. When the Asus arrived, I connected the wire that came with the Asus to the back of the belkin and plugged that same wire into the Asus. Plugged it in and I can see it in WICD (default unsecured channel 11). I was thinking of just leaving it there by the belkin and extending the belkin's range with it, sort of like a booster. However, I can't get on the asus. It shows in wicd and tries to connect (unencrypted) but does not. I tried a couple of things but they didn't seem to work. Can you give me some suggestions? I am obviously doing something wrong. Do I need to replace the belkin with just a regular, non-wireless, router? The directions seem to say that I should wireup to the belkin and adjust the settings in that, but I fear that if I do, I won't be able to get online as I am doing now, using the belkin wireless.
