I have a 2820Vn which is setup as DHCP server.

Wired connections to it get DHCP ok

Wireless connections to it connect ok and then fail when trying to get a DHCP address. On the odd occasion it does work. Very intermitent though.

Any ideas ?

I seem to be having the same problem although I am on the latest software version 3.3.1_232201. This was supposed to have fixed this but two PCs connected wirelessly on my network are getting random disconnects from the internet even though the wirelss signal is strong. So my assumption is its the DHCP problem come back!
