Hi. Sorry for the long response time. I tried the different mainline
kernels but none seemed to solve the issue.
However, I upgraded the proprietary Lenovo system firmware with
fwupdmgr, and I have not seen the problem since. This is the output of
fwupdmgr get-history

Title:
Wi-Fi connection drops periodically on Ubuntu 24.04.02
Status in linux package in Ubuntu:
Incomplete
Bug description:
Connection to a an access point drops every 15 seconds or so on fresh
installs of Ubuntu 24.04.02 on several machines in the Thinkpad P14s
series. This problem did not occur on fresh installs of Ubuntu 20.04
with exact same hardware.
Steps to reproduce:
1. Install Ubuntu 24.04 on a Thinkad P14s series laptop (tested with 21J5,
21K5 and 21K3)
2. Start an access point such as the hotspot from a phone
3. Connect to the access point with `nmcli d wifi connect "<SSID>" password
"<password>"
4. Start pinging the gateway, shortly after, the connection drops. This looks
like so:
64 bytes from 192.168.12.1: icmp_seq=15 ttl=64 time=5.81 ms
64 bytes from 192.168.12.1: icmp_seq=16 ttl=64 time=7.48 ms
64 bytes from 192.168.12.1: icmp_seq=17 ttl=64 time=7.96 ms
From 192.168.12.202 icmp_seq=18 Destination Host Unreachable
From 192.168.12.202 icmp_seq=19 Destination Host Unreachable
From 192.168.12.202 icmp_seq=20 Destination Host Unreachable
5. The connection is restored and the ping continues

Any other device connecting to this hotspot (including the same computers on
Ubuntu 20) do not face this issue. The affected computers all have a Qualcomm
QCNFA765 Wi-Fi chip and use the ath11k drivers.
I attempted the following to the fix the problem:
* Disabling powersave in NetworkManager
* Trying various kernel versions including 6.8.0, 6.11.0 and mainline
6.14.0-rc4
* Change band and channel of hotspot
* Disabling IPv6 in the NetworkManager connection
