I've upgraded my broadband to infinity - which is much better. My issue is that the hub could not be fitted in the original place and the engineer re-routed the wiring outside to a different location in the house. My problem is that I have security cameras which were hard wired close to the old router. I don't really want to go to the expense of having the cameras re-wired. My question is: Can I re-install my old router (which won't have fibre) to run in conjunction with the new hub which is fibre? I can't connect the two hubs with an ethernet. Hope all that makes sense
No, you can't connect 2 routers to one phone line.
You could use your old router as a wireless access point/Ethernet switch but you would need to connect the 2 together via Ethernet
Not entirely sure why your new router had to be relocated unless you now have FTTP rather than a copper line.
