Wifi is repeatedly dropped and sometimes cannot reconnect without a PC restart

I know this has been asked plenty of times already and a tonne of 'solutions' have been provided. Many of the solution did not work for me. Edit: The solution did not work, so the problem persists. I am posting this as I found something that seems to have worked and it may be useful for others.

I am not an IT/CompSci person so I please understand that I may not know all the technical ways to fix this.

My wifi has had the issue of 'dropping' shortly after connecting. The problem is consistent but sometimes it takes a few minutes before I lose the connection. When I ping ubuntu.com I get ping: ubuntu.com: Temporary failure in name resolution and if I ping 8.8.8.8 I get

PING 8.8.8.8 (8.8.8.8) 56(84) bytes of data.
From 192.168.178.105 icmp_seq=1 Destination Host Unreachable

Occasionally the wifi will go switch between 'working' and not and I can't see why this should be the case (I am not doing anything different during these times). During these times my ping looks like this :

PING 8.8.8.8 (8.8.8.8) 56(84) bytes of data.
64 bytes from 8.8.8.8: icmp_seq=3 ttl=116 time=872 ms

64 bytes from 8.8.8.8: icmp_seq=7 ttl=116 time=46189 ms

Most often the wifi just does not connect at all.

The wifi is not the 'obvious' problem as I have had this issue for more than three months on over 20 different wifis and hotspots. In all cases the wifi worked for my phone and other computers. Moreover, I can connect sometimes (seemingly randomly) but only for a few minutes. The Ethernet works without a problem and the laptop can connect to the internet via a usb connection to my phone (which is accessing the wifi, not a data connection).

When the wifi is on, I cannot ping the computer from my phone (termux app) and I cannot ping the phone from the computer.

Edit: This 'solution' did not solve the problem. In the end, I upgraded to Ubuntu 23.04 and with that the wifi problem went away.

I found this answer: Ubuntu-server install via chroot netplan wifi network unreachable

This seems to have worked. It has only been a few hours right now but this is the longest the wifi has stayed connected in over three months so I am hoping this really was the solution.

I replaced the content of :

cat /etc/netplan/01-network-manager-all.yaml
# Let NetworkManager manage all devices on this system
network:
  version: 2
  renderer: NetworkManager

using the content of the file below:

cat /usr/share/doc/netplan/examples/wireless.yaml 
network:
  version: 2
  renderer: networkd
  wifis:
    wlp2s0b1:
      regulatory-domain: "GB"
      dhcp4: no
      dhcp6: no
      addresses: [192.168.0.21/24]
      nameservers:
        addresses: [192.168.0.1, 8.8.8.8]

        "network_ssid_name":
          password: "**********"
      routes:
        - to: default
          via: 192.168.0.1

I literally just copied it (even the asterisks). but changing the wlp2s0b1: to the wifi on my laptop. I then ran

sudo netplan apply

At first it seemed to have done nothing. After around 5 minutes the wifi reconnected and has not gone away yet.

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.
