Like others suggested, I tested the unit with a 50' cat 5e cable and all was good

The other 2 units started failing about 2 months ago

Better unit than the one supplied by my security installer

unit is clear on 160ft run.

Kudos to the seller I purchased it from - they advised me that I probably received defective units and advised me to return.

Suddenly first unit started to fail

The units work great if you have connection to connection

BUT This unit looks good on a top of the line 58" Panasonic Plasma and the IR repeator is good.

Since, I have received a new unit and it works great

Once you're set up, it's really a perfect little unit

The unit worked perfectly out of the box but died within 2 months, which is unacceptable for the price
