ŚXT AC mode

Mon Sep 22, 2014 2:59 pm

Hello,
we made some fist tests with equipment with 802.11ac enabledin production sites in NV2 mode so we have AP withsome 5 clients.. Everything seems ok, but after some time there is some critical bug on Wireless to eth bridge. The client is hanged on AP all over, but datas are no passing bridge. The only solution is to restart device (but not always helps).
Then sometimes appear the log trigger System rebooted because of kernel failure. Used ROS is 6.19

Insider,
how you have configured devices? as wds?
if yes, did you added to bridge wlan interfaces on AP side?

Does pings jumping if pinging to remote sites?

No, we dont use WDS mode any longer, We do use AP Bridge and Station bridge, and than adding interfaces to appropriate bridge

Thats interesting. what frequency mode you are using?
Could you change nv2 to nstreme? For me for now it helped.

Hi,

I to have same/similar problem. Kernel failure - **AP and Client SUPPORT.inf files attached**

Using SXT G-5HPacD sectorial to one client using SXT G-5HPacD.

switched to 802.11n - no success
switched to 2omhz channels - this ACTUALLY CAUSED kernel failure
100 metres distance
checked radio noise - nice and clear

when I do BW test with 951s at each end to client falls over - this ACTUALLY CAUSED kernel failure.

see pics of AP and client

If 6.20 no fix then back to supplier and might have to pick AirMAX but would prefer not to. No choice.

Regards

Aidan
