It is fine when I use wireless w/o wep encryption. (although when I transfer files between two computers using this router, wireless lan is disconnected after few MB of transfer)I can surf web for long, and play counter strike w/o much of lag.But when I enable 64bits wep (128bits also available), it drop my connection after few minutes.So it keep ask me if I want to connect to available wireless network every 2~3minutes.And Of course, if I was downloading some files, then I get disconnected. I had to re-download that again.I can use it w/o wep enabled, but I don't want other people stealing my bandwidth, so I'm going to return this and pay $20 more to get linksys
