Good day to all!

I'm experiecing a strange issue.. I have been using my MR600 since 10 month with windows systems without any problem.

In the last days I have set up a linux lapto (with Xubuntu 20.04). The laptop does not connect to my MR600 network. Actually it deos not see at all, as if it were hidden.

I can connect to it only if I restart the router. As soon as it is ready, I can see the network for a while and connect to it. Somethime it stays conneted, sometime it does not, then no way to connect. 

The problem does not seem due to the laptop, the wifi driver or similar, as it sees without problems any wireless network in the area and it perfectly connects to my smartphone when I switch the access point. 

It's like the router doesn't like the linux laptop only. 

DId it happen to anyone?

Any idea on how to fix?

Thanks in advance,

Amerigo.
