Ive found the problem usually to be a failing TLink, and the necessary 
solution to usually be "replace the TLink with a new Tlink"

I'm never quick to replace a Tlink with another brand, if the Tlink has 
enough capacity for the purpose of the link.
With TLinks, I have solid indicators when a radio is operating properly or 
not. Thats important. With other brands, (like UBNT), its sometimes harder 
to know for sure whether a link is working optimally, from the perspective 
of the end user's throughput. Not to mention, TLinks great for legal 5.4 and 
5.3.

A couple things to check....
I've seen two other things cause the same symptom...

1) The power supply going bad. Fixed by replacing power supply.

2) Out of alignment antenna. If the  antenna gets severally out of 
alignment, for example if the radio is dangling towards the roof because the 
mast got knocked over or pulled out of the wall brick in high winds, and the 
link needs to struggle to stay associated, there can be a huge amount of ARQ 
retransmissions, and it can over tax the software, and evenually the 
software crashes. I dont know why, I'm not their programmer. Maybe its some 
sort of exceed buffer type of thing.  In some cases it will get bad enough 
where the RF communicates, but one side of the link will not pass traffic 
through it, meanting between the wired Ethernet and RF. The quick fix is to 
reboot either side. Because the RF is up, its also possible to remotely 
reboot the CPE or AP side.  And even oif the CPE is the failed unit, 
rebooting the AP will fix the CPE. I dont know why it occurs, but it does. 
When these symptoms exist, often when I do Sysinfo, it only shows a small 
bit of info, and then hangs.

So in summary, before calling a equipment bad, visually verify the equipment 
is still properly mounted.

Please note these symptoms are rare to occur, and do not occur on 
non-defective Tlinks that are properly mounted, with proper link budgets.
