Network Disconnection [LM19 Tara]

Post by WISEGUYTR » Tue Sep 04, 2018 5:25 pm

Hi,

From time to time though my wlo1 (WiFi) stays connected, bur the it cannot resolve IP adresses. (The power management is OFF).

As a workaround I manually have to stop and start once again the networking as it comes back to normal.

The logs recorded below in the sametime:

I was having the same problem with my setup and went to my wireless router and changed the channel. and so far it's been good.
problem here was too many others using the same channel. That may be the cause for you also.

Good luck in finding a solution.

Thanks for your reply, but I checked the router first, but essentially this problem is specific to LM19, as the same machine had LM18.2 and had no problems.

I have other machines on the same WLAN with no problem whatsoever.
