One of my wifi cards arrived today!! Thank you so so so so much!!
Took the opportunity to do a big refurb of my MacBook, including tightening the screen hinges, replacing the smashed clutch cover and currently replacing worn and broken keys.
Only trouble I've had so far is with the Apple Watch unlock - fiddled and fiddled to get it working then it worked twice and then stopped. Haven't yet done a PRAM and NVRAM reset or signed in/out of iCloud yet so thats the next two things to try.
My next potential upgrade is either to a secondary SSD, or an internal Blu-Ray drive
