Can you try loading the v1.02 version see here?

Hi, I've signed up for an account just to share the solution of this commonly encountered problem with firmware upgrades
Non of the other reset unit, using mydlink, out of DHCP range IP addresses, changing browsers or disabling AV/ FW worked for upgrading my 2330L from V1.00 to V1.12
However - when I used a stepwise approach to upgrading ; V1.00 - V1.02 then V1.12 , this worked a treat with the ethernet/wired connection
Someone should add to the FAQ that the firmware is incremental / stepwise!
Hope this helps someone save 3 hours
