Ubuntu 22.04 Wifi drops after about 1/2 hour

I have to restart my computer about every 30 minutes because the wi-fi drops off. I am new to Ubuntu and not very skilled with the terminal. I did try the first solution at this link 22.04, wifi keeps disconnecting for a few seconds frequently Did not solve the situation and now my computer has to go through several extra steps to turn on. I also set the power save to "off" (i hope) No solution yet I also installed a "patch" for the problem. No luck

Any ideas? PS it is not the wifi itself. My other identical computer is still using windows and wifi is always strong.

Thanks

This won't help your WiFi, but for your ethernet interface you should install the `r8168-dkms` driver. `sudo apt install r8168-dkms` I suggest that because the `r8169` driver on a RTL8168 is asking for trouble and is very unpredictable.

Look at the network logs with the terminal command: `sudo journalctl -b 0 -u NetworkManager`. Read `man journalctl`.

I used the sudo journal... command above. Just got hundreds of lines of identical text. I don't know what "Read man journalctl" means for me to do.

Most people don’t grasp that asking a lot of questions unlocks learning and improves interpersonal bonding. In Alison’s studies, for example, though people could accurately recall how many questions had been asked in their conversations, they didn’t intuit the link between questions and liking. Across four studies, in which participants were engaged in conversations themselves or read transcripts of others’ conversations, people tended not to realize that question asking would influence—or had influenced—the level of amity between the conversationalists.
