Guys, I have a problem with Unifi and the wireless router they provided.

After 30 mins of surfing, I would suddenly lose connection to the wireless router.
Actually, I'm still connected (both the unifi "modem" and the wireless router) but I can't surf on the internet anymore.
What I usually do is then to switch to another wireless network and switch back to Unifi.

This is very annoying because it means I can't download stuffs which will take more than 30mins for the full download (huge files).
And then I have to start all over again.
Looks like my old Streamyx more reliable.

Anyone from Unifi care to help or any suggestions from LYN members here?

Btw, I'm using a MacBook.
