Yes you will (should!) get the bandwidth advertised on ethernet cable connected devices. Whether you can achieve that on wifi is another question
🙂The connection you describe is useless for "modern" connections. A 4K UHD Netflix stream needs ~25Mbps, a HD stream needs about 5Mbps - per device! So going up to a 100 or greater packge should solve all of your woes.
I am in South Manchester too (Didsbury) on the 200 package and have no bandwith issues at all
