Draytek Vigor 2820n wifi problem

[itsfuzzy]

I am having a head wrecking issue with a Draytek 2820n i installed for a client. Its just connecting to it with wifi from a Dell Inspiron N5010 Win 7 64bit. It connects to the router then internet access drops, comes back drops again and goes in a loop like this. I though maybe it was DNS so i set open dns and then google dns on the router and no luck, did the same for his wifi adapter and no luck. I updated his wifi card, a broadcom half wifi card to latest driver and still the same. If i cable up the laptop to the router it works fine, and the really weird thing is when i re installed his old Zyxel modem router his wifi works fine! I even set all the Drayteks wifi settings to match the Zyxels, and it still drops im at at a loss! All other wifi devices on the network can connect

Does that mean the PC associates but does not get a DHCP-assigned IP address/gateway, and elects to de-associate and try again?

If so, the DHCP failure is often due to an encryption type/mode/key mismatch.

Otherwise, try a static IP on the PC to eliminate DHCP from the suspects.

Yes it does get an IP from DHCP, but it does not allow the laptop to go onto the internet. It can connect to the admin page of the router if it desires, but no traffic is routed onto the internet. I just get the yellow exclamation mark intermittently on the wifi status bar that indicates no internet access, i cant figure it out at all.

Do you have a default gateway defined on the PC?
