I live in a three storey with the office on the ground floor. The routers and connections are on the middle floor.  The wi-fi in the office (I think due to the concrete roof in the internal garage was poor until I got the AX90.  Just had BT full fibre fitted at now up to 300mb - but only on the middle floor. Main iMac on the ground is poor at 35mb.  With the AX90 connected it is 280mb. So it seems it is best to keep it connected - but how do I connect my two digital phones.

I was hoping to get rid of the AX90 - just why are provided hubs so poor?
