Yes I am also encountered a weak signal from the 2820 router. I just set a wireless router in my coffee shop using the 2820 router but I got a weak signal from my laptop.

But after moving the place of my router it seems the signal came fast strong signal. I think there's a interference in my room that lessen my wireless signal.

Try to change the location of your router in open wide air.. This may helps.. Cheer!

You could also check the transmit power of the router using telnet command "wl ht txpower"

Is a higher or a lower value better (I'd assume higher, but I've never actually seen it documented anywhere).

Edit: added missing word 'never'

From memory its 1 to 5, 5 being the highest.
