Ease of Use

I ordered an Asus wifi router and received a Samsung blu-ray player instead !!! I want my money back or my Asus router. There is no paperwork or return label inside the box.

Does not compare to cisco/linksys. This bad boy gets the job done. I read all the negative and all the others that followed directions and I strongly recommend following directions on the disc/quick setup guide! Running winxp on cable modem. This thing rocks!! Read More

Good Experience So Far

on 2/28/2013

So far so good, but only 2 days into it. Only issue is legacy 802.11A connections on 5ghz don't see/connect. One A device won't find the broadcast SSID, even after trying legacy/WEP and other modes designed to work for older stuff. That aside, this device is great and would have otherwise rated a 5 overall. A bit costly. Great range on 2.4ghz, not sure on 5ghz since my older devices aren't working. Easy setup. Read More
