Hi John,
Not sure you should have posted that where Zuku is watching.... :)
However, I also have the same problem. LAN is fine but wireless works for a few minutes then stops. Comp still shows connected but there is zero network traffic. I have asked Zuku customer care about it but getting this past their thick heads is too much for me. They don't understand the concept of laptop connected over wifi but no data traffic. In the very next communcation from them they always say "wifi not working" like its dead completely and some say internet not working. Gormless twits.
I've given up. If you get anywhere, let me know.
