I have RevA and 1.12NA. Don't see much of a change from 1.11. I had a weekly or so problem where it would lock but just the other day found the "DNS relay" trick and that seems to work.
My problem is Guest Zone.... It does not work. I have no security set up on the router (guest or non-guest) but do filter on MAC address. I live 19 floors up so I doubt people will "hack" into the router.
To be friendly to the neighbors, I decided to turn on guest zones. However, I have found that unless a MAC address is entered (for the secure zone) in the MAC filtering table, there is no way you can connect that computer. It does shield correctly, in that if I use my laptop to use the guest account, I can't go anywhere but the internet.
Does anyone actually use the guest zone? I'd like to.
