i was looking for help with an LG 42LH50 HDTV--an internet enabled device like the blu-ray player in this thread--a google search brought me to this forum--thankfully as LG tech support was not helpful. The 42LH50 is a wired device so i omitted references to wireless setups.
Under Advanced --> QOS engine --> QOS engine setup
Uncheck "Dynamic Fragmentation"
Advanced --> Firewall Settings
Uncheck "Enable anti-spoof checking"
Under Advanced --> Secure Spot
Uncheck "Enable Securespot services"
Under Setup --> Internet --> Manual Internet Connection Setup:
Uncheck "Enable Advanced DNS Service"
Under Setup --> Network Settings --> Router Settings:
Uncheck "Enable DNS Relay"
Under Setup --> Network Settings --> DHCP Server Settings:
Check "Always Broadcast"
i included -set port forwarding for 32768 TCP and UDP- from jejolley post
i did not change the DNS server setting on the HDTV or router as suggested.
i put the device on DMZ and enable static ip address.
Hooray--i was finally able to watch a netflix movie on the 42LH50 after weeks of fruitless effort.
phone/email support from the vendors involved was not useful. Reply were of the "make sure the unit is plugged in" variety. Fantastic router none the less. Thanks again to posters. Paul
