I have recently upgraded to Gig 1 and the new Hub 4. I have had telephone support and an engineer visit but to no avail. The WiFi speed (tested on ookla and Sam knows) is generally around 100-150 Mbps, wired I have seen up to around 800ish. My question is would I. E better acccepting that the hub 4 is a poor WiFi router, pop it into modem mode and have an external WiFi router? Many thanks for your advice.
