Just the one BT supplied modem, and one router, a billion 7800DXL.
I did have some spare modem/routers until Fibre came along 3 or 4 years ago. But none were Fibre capable, so all went in the council’s waste electrical skip. It felt good driving home that day, knowing I had a little less junk in the cupboards.
Although all of my router collection before the clearout still “seemed to work”, when I took the lids off, most had obvious capacitor failures so the skip was the right place for them, imo, component-level repair being not an attractive option on modern electronics.
If you asked how many 1960s/70s transistor radios I have, that would be a different story. All laboriously restored by your truly, and fully working, with batteries installed ready for service.
