I thought it was a classic case of 'you get what you pay for', and having cheaped out on this £7 replacement dongle ( my SB Components 8188CUS dongle's radio subsystem seems to have gone FUBAR), I was beginning to think I'd thrown money away, when I realised that TP-Link's 'support' of this dongle for RPi is stretching a marketing term to breaking point. I've just purchased a TP-Link WN823N v3 dongle for a Pi2B that will be left in a cupboard monitoring an energy meter, and very nearly regretted it.
Joined the forum to say a huge thank-you to you for curating/developing this install-wifi mechanism which has saved me hours.
