Running a MacBook Air, version 7.2 and Ubuntu 23.04. I have a decent wifi router with good signal strength. I awaken the computer and when the computer connects to my wifi network I begin my session -- except sometimes I get prompted to enter my network password. Sometimes I will get prompted multiple times before I'm connected. Once connected, I will check my e-mail or start my browser (Firefox)...and then the wifi connection drops. I'll re-select my network and connect. Sometimes not. Sometimes the connection will drop again, and may even prompt me for the network password again - sometimes multiple times, before finally tying a knot that will not slip.I don't know if it is a Broadcom issue, or what. I am aware of a log viewer in my utility folder, but there are 4 different logs to view and am unsure what to look for. I'm in over my head, again. This was also happening in Ubuntu 22.04 but a little worse in that version, I think.

The wifi dropping issue seems to have been mooted by recent updates. There have been no drops since August 1.

Your wireless may be dropping because there are two wireless access points with the same name and password. This is typical when you have a 2.4 gHz segment and a 5 gHz segment of the same router. Your wireless may be roaming, looking for a better connection. If this is the case, I suggest that you rename the access points; something like myrouter2.4 and myrouter5.

After making these changes, reboot the router.

If you don't have administrative priveleges for the router, I suggest that you bind to the 5 gHz segment by its MAC address like this: 19.10 Ubuntu automatically connects to a weaker Wi-Fi
