My broadband speed fluctuates

[Simon+Ewell]

I have recently upgraded to sky q and new sky hub (5 weeks ago) but my  broadband speed fluctuates, speed test over wifi. Most of the time it's over 60mbps but can then immediately drop to under 15mbps. Any suggestions - have reset the hub and checked all the connections. Router statistics as below.

@Simon+Ewell  How are you measuring the speed as the speed to the hib is just under 80mbps down & 20mbps up.

Are you doing them using an ethernet connected device?

Hi - testing via wifi connection, mobile phone and/or ipad. Never had an issue prior to this new Hub. Thanks

@Simon+Ewell  The router stats show no issues, speed test over wifi are on the slowest part of the network try an ethernet enabled device and speeds should be near the speed to your hub.

Via ethernet and via my PC I consistently get 70mbps d/load and 16mbps upload. Just dont understand why the wifi drops in and out, the only change to the equipment is the new Hub

@Simon+EwellLooking at the router stats that you provided. There has been no drops on either the Wi-Fi or Wired with around the same uptime as the system and the connection time.

@Simon+EwellCan you also do this on a wired device please.
