My WIFI disconnects at random intervals

My WIFI connection seems to be randomly cutting out. Signal is fine and 19.04 is fully updated. I don't get this issue on any non-Ubuntu based distribution.

I'm using an Entroware Triton with an Intel Wireess card, with which I'm had no issues until 19.04.

Look for this issue. It's same problem. Link

Thanks, I'll report back once I see if that solution works.

Okay, it seems this hasn't solved the problem. Drivers were installed during the process but every now and then it still disconnects.

I would recommend opening a bug.

I think I've worked it out. It seems that for some reason, Ubuntu MATE wants to switch WIFI bands from time to time, so I just set the band from "Automatic" to "A (5 GHz)" and so far so good.

I'll keep you all posted on whether this works fully, but it's been a few hours and I've not had an issue.
