Unfortunately, I can't assist with home network setups in the forums.
I might check the Network and Wireless forum settings, and there are posts that may be able to assist.
I have a WIS09ABGN that behaves strangely on a LED UE46?7000.
I do the configuration on TV OK: wireless, find wifi, connect (WPA2-PSK security), input passcode, test connection ok and signal green.
I try to connect my TV with internet@TV, (at some point it did connect and started to install some components). Then when I try to connect it gives a DNS connection error.
When I go back on the config screen, and test the connection, all pass but the 4th step (DNS Server). Wifi is unchanged, all other devices work fine (wii, PS2, iphones, laptops...). Once every 10 times or so it passes the test, but again when I go to connect to internet is gives an error message...
My router is a Thomson 585v8 (G/N). I had the same (and worse) problems with a Linksys WAP54G, never got to connect.
Can you please advice?
