EE router ethernet ports not open

[torode]

I have a electric central heating system installed that works off a hub which is connected to my wifi  which is a EE router but none of the ports are open they have sent 3 different routers but none open i have been on the phone over 3 weeks trying to convince them it’s their problem  i have tested the ethernet ports with new cables linked to tv  a game station  and a computer none will open and still they say its not their router what more can i do. ??

@torode : What do you mean that Ethernet ports aren't open? If you're connecting your central heating hub by WiFi you don't even need to use the Ethernet LAN ports.

It's impossible that all the LAN ports on 3 routers are all faulty.

Perhaps you are confusing them with incoming software ports that a server might need opened but I doubt a central heating hub would need any.

Which EE BB plan are you on? What EE router do you have?
