Ok, installed and booted off the oem kernel without the pcie_asm kernel
parameter and the speedtest-cli results are promising.

Title:
Driver r8169 causes very slow download speed due to ASPM
Status in linux package in Ubuntu:
Confirmed
Bug description:
Running Ubuntu Server 21.04 (kernel 5.11.0-34-generic) and have run
into a serious network issue where the internet download speed is
around 25Mbps on a 150Mbps connection!
My setup:
Lenovo Ideapad 300S with a wired Ethernet connection.
Running Ubuntu Server 21.04 (kernel version 5.11.0-34-generic).
Wired Ethernet connection with RTL8111/8168/8411 PCI Express Gigabit
Ethernet Controller (r8169) driver.
My contract with the ISP is for a 150Mbps download speed.
My problem:
The download speed is extremely low, around 25Mbps whereas my upload
speed is 'normal' around 80-90Mbps. I use 'speedtest-cli' for
measuring the bandwidth, by the way.
This problem does not happen on an Acer Aspire One laptop running the
same kernel and connected to the same router.
After scouring through countless articles, I noticed that there were
lot of issues with the r8169 driver and the RTL8111/8168/8411 PCI
Express Gigabit Ethernet Controller subsystem.
What eventually fixed the issue for me was setting the "pcie_aspm=off"
kernel parameter during boot. But I strongly feel that is a
'workaround' and not a solution to the real problem, which is the
r8169 driver has regression with newer kernels, hence filing this bug.
Thanks in advance for all your support! I'm a big fan of Ubuntu!!!
