Lenovo Y510p has been out for more than 7 years, to this date I am still using it as my go-to workstation. The specification is quite old and I have upgraded and replaced everything that I could, except the wireless card, due to the infamous BIOS whitelisting.
Thanks to techinferno, there are people sharing the modded BIOS and the steps are listed in the following article:
Note: In order to downgrade BIOS, people will need to turn on back flash feature in the BIOS setting (press F2 on boot)
Here is the zipped file if you need it.
I bought a wifi card that has BCM4352 chip on it, the chip is installed on a PCI slot (check via lspci). on Manjaro, you need to install network-broadcom-wl via mhwd:
sudo mhwd -i pci network-broadcom-wl
Now my wifi speed is upgraded from 20Mbps to 500Mbps. Very nice!
