It happens from time to time with my Dell Inspiron as well (I happen to
have 5425, 7425 and 5625 models)
The mt7921e module reload seems to fix the issue.
I've created a root owned executable file at /usr/lib/systemd/system-
sleep/mt-wifi for it as
#!/bin/sh
PATH=/sbin:/usr/sbin:/bin:/usr/bin
if [ "$1" = "post" ]; then
modprobe mt7921e
elif [ "$1" = "pre" ]; then
modprobe -r mt7921e
fi
exit 0

Title:
mt7921e wifi fails to resume after suspend
Status in linux package in Ubuntu:
Expired
Bug description:
After resuming my suspended PC, the wifi becomes unresponsive. The
only way to get it working again is to do a full reboot. I'm using
Ubuntu 22.04 LTS Jammy and my wifi card is:
MEDIATEK Corp. MT7921K (RZ608) Wi-Fi 6E 80MHz using `mt7921e` driver.
This is what I can see in the logs:

I really appreciate someone's help to fix this behaviour.
