Does your PC have a wired ethernet connector and can you attach to a router using ethernet cable ?
Did you do any package upgrade/update between the hardware working and now not working ?
Was a reboot required after the upgrade ?
If there wasn't an upgrade/update, what else changed ?
If nothing changed, then you may have faulty hardware - do you have another dongle you can use or borrow?
It looks like the 'official' TP-Link drivers for TL-WN821N available (to me) to download are for linux kernel versions 2.6.18 to 3.10.10 so I wouldn't be trying them as a first choice. There may be a PPA (Personal Package Archive) in which a developer has packaged network drivers for your hardware that works with more recent Linux kernels.
You will need to confirm the chipset in the hardware and the kernel version to check.
To start, answer the questions above and run the following command and post back the results please.
