We have seen this from local oscillator and/or CPU clock oscillator
interference from wireless radios used for Internet access. The radios
in question were a Trango Fox one time and a YDI Etherant another time.
I am guessing any radio using an external connected POE driven board
over unshielded twisted pair could act as an interfering source. Brand
is likely not important.
This was corrected using RF Ferrite Beads installed at the cat 5 cable
right as it comes out of the radio and at the POE end as well. If this
does not fix it you will have to move the wireless radio or TV antenna
apart farther than they are now.
Cheers,

Hi Bill,
I am copying Marlon on this so he will reply as soon as possible. He

Subject: Interference with TV
We have good internet speed most of the time and I am happy with my
setup. Occasionally we loose the internet for some reason, and I have
to shut off the power to the receiver. This always seems to reset
everything. All in all we have been very happy, however lately we have
been having a problem which seems to be getting worse as time goes by.
Lately, our TV picture becomes pixilated and breaks up, and the
sound is also disrupted. It seems to happen anytime. (maybe some
program on the computer is accessing the internet?) If someone gets
online the TV becomes so bad that at times it is unwatchable. This
seems to have become progressively worse over the last two or three
weeks. If I turn off the power to our internet antenna, then we have
no problem with the TV at all, so I can only presume that the Internet
antenna is disrupting the signal that our Dish Network antenna is
receiving. The Dish Network antenna is a duel LNB antenna and this
problem only occurs on certain channels, so maybe only one LNB is
bothered by the internet antenna? Is the internet antenna failing and
sending out interference? Is one of the LNB's on the Dish Network
antenna failing, or is this just signal interference, and if so, how
can we get rid of it?
We would like to be able to use the internet at the same time that
we are watching TV, so anything you can do to help me would be
appreciated.
Thanks
Bill Dale
