I have rb433ah, dual nstreme, 2xcm9 minipci, 802.11a. It freezes once a week. Icant ping device, just hard restart helps.
This day, it happens twice a day. Bootloader was there 2.29, I upgraded it to 2.39 and I will see what happens.
Can it be cause by that?

hw-retries: 15
hw protection threshold: 0
frame lifetime: 0

I changed routerboard, also I upgraded routeros to newest version. The problem still occurs, it freezes one a month?
What can it be?

10.10.201.6 is ip of device connected to ethernet2(my main gateway), to ethernet 1 is connected another routerboard to see if all ports freeze, but it seems that not. It causes lost of ping: it is about 6% packet loss...in this device runs nstreme

Mikrotik please react. Do you sleep?

I turned on autonegotiation and no packet loss, and no eth up, down.
But with turned autonegatiation routerboard will reboot once and more time a week(freeze and I must switch it off from electricity).

Time to change for better products UBNT and ROCKET????
What mikrotik, are you able to react?

i have same problem here and after 2 years is still no solution ?

previously it was this problem with ethernet up down, now i have nstreme dual freezing / lockup - only some kb/s and only reboot helps

Now I confront with new problem:
Nstreme on 802.11a, on one site rb600, ros v6.27. Disconnects, almost every 2hours, despite great signal, SNR, minimal noise....after changing to nv2 problems dissapears, but lattency is high...


can anybody help?
