NV2 blocks communication

RouterOS Wireless Networking
1

Hello everyone, First of all sorry for my bad English.

I explain the problem: i have a network composed by aps Omnitiks and clients SXT 5HPND
I am currently using 802.11A Nstreme and everything works correctly.
I migrated to 802.11n NV2 and apparently everything works correctly But randomly I lose communication with some clients, the connection remains established but can not send or receive nothing.
.
I am using RouterOS V5.26.

Greetings and thanks to all.

Ok, thanks for your answer.

Should I upgrade Omnitiks and SXT or only Omnitiks?

I’d upgrade both.

Hello pukkita, i did upgrade to 6.31 and the problem persist.

do you know what’s the problem?

Thanks for your help.

6.31 is not good version. Use 6.30.4 or 6.32.2.

but this problem has already occurred in several versions.

It could be a bug that nv2 still not fixed?

or you think that upgrading to version 6.32.2 fixes the problem?

Thanks for your answer jarda.

You would need to install it to your lab devices and test if it is better or not before going to real life.

Hi,

You can try and increase the TDMA Period Size to 4ms.

Also try lowering the distance so that the distance is 5km more then the furthest cpe.

with omnitik I would stay on 5.xx and nstreme, works much better than nv2 in 6.xx
