I have been using both Senao and Engenius EMP-8602 mpci cards since there release, and have not had any issues operating them in the 2.4ghz bands. However, while testing some equipment this past week I noticed problems with the RouterOS when operating any of the 5Ghz bands.

Setup:

RB532
minipci #1: EMP-8602
minipci #2: nothing
PoE power

As soon as 5ghz is enabled on the emp-8602 the rb532 reboots itself, it restarts fine loads RouterOS, then about 10s later it reboots, this continues until either the emp-8602 is disabled or set to a non-5ghz band.
I have repeated this with 5 different emp-8602, and 4 different rb532s and 4 different PoE adapters. RouterOS does not create any support file automatically and from all indicators it appears to be power related.

Additional info during diagnosis:
All rb532 and the respective PoE adapter can run a SR2, and SR5 @ 24 mbps (highest tx output) simutaneously, without problem.
The problem appears to be power related, and RouterOS related.
When manually dialing down the tx-power to 1 on the emp-8602, the system does not reboot itself when setting the card to 5ghz.

It would be nice to know what it causing the problem. Has anyone else seen this problem. It reminds me of the early SR2 issues with Mikrotik.

Have you disable wathdog on MK?

Have you disable wathdog on MK?

HI!! I have the same problem... and I have allready disabled watchdog on my MK ... anyone was able to solve this issue ??

thanks!!

The answer is that they are low quality cards. Senao rush out with these cards when they should have held on to perfect it.

I tried in 2.4 band and never work good, just only change to the 5ghz band and work perfect, I dont understand what is the problem
