I suck at home networking. A recent broadband change and the introduction of a NAS has made our WiFi so home a bit of a mess and I’m looking for someone who knows what they’re doing to sort it out

I have a Community fibre provided linksys router and I have added 3 linksys extenders to improve coverage across my 3 floor house. 2 of these 3 extenders have stopped working and just display redlights. I have used Community Fibre support to try resetting these but it has not worked. I bought a new base router (TP-link Archer550) but I cannot get this to register an internet signal from the Community Fibre modem and they have told me they cannot provide support on 3rd party equipment. I need help either getting the original equipment to work or with setting up the new TP-link router I have bought.

I need assistance setting up an extended Ethernet/network cable, connecting it to the extender, and routing it to the backrest. See images for reference.

I have started to network ethernet through the house for two locations upstairs, but fitting (pass-through) RJ45s is not working. I get green lights on the tester but computers don't see internet connection. I think it really needs 'pro level' tools to get the job done right.

I need to change the WiFi network on my HikVision CCTV camera system. I recently got a new broadband provider and need to switch the device across. I have the HikVision NVR system and app. Thanks

I've recently setup a unifi network in my home using a USW Pro 23 POE+ and 6 access points, however it is working but dropping and I am not sure I've set it up correctly
