I recently switched to Fios and now my Samsung LN46C670 will not connect via wireless adapter and the Actiontec M1424WR router. Has anyone else had this problem? Any solutions? Thanks
Are you sure you are entering the WEP key properly?
My suggestion is to change the wireless Security from WEP to WPA 2 with Preshared Key.
Its more secure plus you can choose the passphrase you want and can remember.
Give that a try and report back the results.

Note there is a bug with some Samsung Tv's software for larger WPA2 passphrases. I had to shorten mine to 18 characters before it would reliably connect.
