Your instructions worked perfectly and accuweather is now set and running.
It doesnt seem to be downloading the correct file from mediafire.
Installed 3.50c after clean reflash.
Typed the IP as instructed, got to the pnp page but no accuweather option.
I plugged in the IP Address and Gateway and it works perfectly both when connected to the network and also with the network unplugged.
Thank you Palindrom for fantastic help and Castalla for encouragement.
