Comtrend PowerGrid 9021 -- "Status" keep on blinking red light

http://www.comtrend.com/links/126$product.htm

Today just changed to a new pair, and now it cannot work already
The "Status" light keep on blinking red colour

How to solve this problem?

Hi,

Try swapping them over. By that I mean connect them the other way round, the one at the computer is swapped for the one at the router etc. OK?

not working. status is still blinking red light

OK,

Well if there is nothing else to configure, the network cables worked before & you haven't changed anything else, they sound faulty.
