It’s copper wire via phone line here, SRS. They do have fibre in Cromer which is about 2 ½ miles from me but I don’t see it reaching us in the foreseeable future.

My network is a hard wired GB (doubled, mostly for reliability, up via LAG for the main trunk) one with an AP plugged in at either end for wi-fi. This gives excellent Wi-Fi in the LR and my room where it is most wanted but with things poorer (although now much improved with the relocation of LR AP) elsewhere.
