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.

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.
