Sorry for the late reply. I tried to connect to two different access points which use WEP based encryption. Actually, both APs are from the same ISP and use an older router which is why they use WEP and not WPA2. What seems to happen is that if I hit the connect button using WISP or the other mode provided, all it does is sit there. Basically, nothing happens when I hit the connect button. I’m not sure if this is particularly a problem with this ISP’s router. I was under the impression WISP needs to be supported by the router so that it can provide information to the repeater. However, I did ask myself why if any old adapter can connect to WEP without it needing any extraneous information, then why couldn’t the repeater? I’m pretty satisfied with the repeater and am waiting for the 5ghz one to come out now.
