This is also the solution to the question “How do i get WiFi working on Linux on X laptop?” Assuming your laptop isn’t a Lenovo with whit-listed WiFi modules.
Replaced the craptastic wifi module in my HP notebook with a nice Intel AC 9260.
Does a magnitude 30 better job (before: 2Mbit down, 1.9Mbit up, Now: 60Mbit down, 60Mbit up). The limiting factors is only having 1 antenna.
Main benefits: swaps the FN/CTRL Key (optional), disables the wifi card whitelist and enabled SATA 2. Also much newer than my old BIOS, so quieter fan profile.
The card I used is: Intel 7260HMW -W041 it must be a Mini PCIE NOT M.2
Also the X61 uses a full length card and this is half-length you will need an adapter. An example name is: “Half Size To Full Mini PCI-E PCI Express Adapter For WiFi Wireless Card”
Ram upgraded from 2GB to 8GB. Officially 4GB is supported, but in reality you can get lucky like me and get ram that works. I am using Samsung M470T5267AZ3-CE6 which is 4GB 2Rx8 PC2-5300S-555-12-03 sodims
HDD to SSD: 80GB seagate HDD to 240GB Toshiba OCZ TR200
Pretty snappy now
I don’t have the skill to do the TN to IPS swap on the screen.
