Sure its possible to have a radio that is failing. All I can say is....the easiest and quickest thing to do is to 100% rule out everything else. I have to admit, I jumped to think I had a bad radio twice, even go the replacements shipped, and both times it ended up being cabling after all. The Apexes are pretty solid.
There are so many possible ways CAT5 can go bad. And I know, the odds of two cables going bad, (the management and Data) doesn't sound likey, but its possible. the APEX can be powered up by ether management or data cable. You might want to try powering from the other one. For cable damage, the big things are corrosion on the pins, or a bad crimp to one of the pins. Those things are hard to spot, and dont always surface for 6 months or so.. Cable blows in the wind, link goes down, or overheats or shuts down because not getting enough current or to much while shorting out. Now when the APEXs first came out (like the first batch) there was a manufacturering flaw with a part that I think effected Ethernet life, but Trango proactively recalled them, like days after they shipped, and gave free repairs on it. (I was impressed, very responsibly done) But that was ages ago.
