@danjjl, nope. It's a regression in backport-iwlwifi-dkms. Should be
fixed there.
Also reproducible with another model: Intel Wireless 7265 [8086:095a]
subsystem [8086:5202], which is 7265NGW BN.
** No longer affects: linux (Ubuntu)
** Changed in: backport-iwlwifi-dkms (Ubuntu)
Status: New => Confirmed

Title:
Intel Wireless 7265 [8086:095a] subsystem [8086:5110] WiFi is
extremely slow
Status in backport-iwlwifi-dkms package in Ubuntu:
Confirmed
Bug description:
On a fresh install of Ubuntu 20.04, WiFi connection is extremely slow.
For example loading https://ubuntu.com takes 200 seconds on WiFi and 2
seconds over ethernet.
On the same computer, Windows 10 has no such problems with WiFi.
The chipset of the laptop is an Intel Corporation Wireless 7265 [8086:095a]
(rev 59)
using the iwlwifi driver.
This issue was not present on my previous Ubuntu 18.04 install.
The issue is present on the latest 5.4.0-26-generic kernel and is also
present on the -25 -24 kernels.
Here is a dmesg log during boot: https://paste.ubuntu.com/p/9ccMnSDcc7/
