Ok, this works for an ethernet connection and maybe for wifi as well, I didn't try. Ist, you must stop the tv trying to connect via wifi, by disabling this option. 2nd, if you can't connect automatically using the "wired" option, make a note of your internet numbers, IP address, subnet mask and gateway before selecting the manual option. Input the same numbers but change the last number as follows. Ip address use 100, subnet mask, 0, gateway 1 and finally DNS server 4.2.2.2
This should work, but if at times it doesn't, try to connect automatically and then revert to manual which normally does the trick. GL
