I recently bought two unit for myself and a friend, thinking the features and price of this model were splendid.
Unfortunately we are both hitting the same problem: Erratically slow speed. It irregularly become extremely slow, and often drop connections. Gmail and video websites are particularly bad. Other websites will be ok. It's completely irregular.
I'm on ADSL through PPPoE, my friend is on cable. Both our accesses work wonder when we connect directly to the modems (so it is NOT a ISP issue).
My router switch is on, I've upgraded to the lastest firmware, the movie engine is off. Configuration is fairly standard.
I brought back my unit to have it exchanged, and I'm still having the same exact problems with the new machine...
I actually even get this issue when trying to connect to the router by LAN.
