Just finished a simple upgrade of a computer's internal wireless adapter with a TP-Link AC1300 PCI Express Adapter.
The existing wireless adapter's drivers could not be updated to run properly on Windows 10, and so was beginning to not pick up all the WiFi SSIDs in its vicinity, and at times would completely drop the signal it was connected to. Time for an upgrade.
The only problem encountered with the install was that the computer wouldn't boot. Even after disabling the internal wireless card the computer still wouldn't start. So one person online suggested putting the new adapter into a different PCIe slot. Why you might ask? Something to do with the configuration of the mother-board, but it worked.
See the video below for a quick overview of the install.
