@Philbert yes, it's a WiFi6 and it received good reviews from the users. Also, I managed to obtain a 40% discount on the price so I think it's ok.

@Philbert thank you for your help. I contacted my provider and unfortunately they don't provide an external ONT. They are giving me a modem router with embedded ONT, so I won't be able ti reuse may...

I'm using Archer VR2800V with FTTC at the moment. Can I use it on a 1Gb FTTH with an external ONT from the provider? May I suffer performance limitations?
