Hi Gary,
I hardwired to the hub earlier to check upload speed and try a process of elimination as I have a Virgin Powerline Wi-Fi booster connected at the power socket. Removing the adaptor didn't seem to have any real impact.
I'm currently sitting using Wi-Fi
Splitting the SSID into 2.4 & 5 has helped improve the DHCP provided DNS latency and Internet DNS Name Resolution latency to 100% (it was previously 80-90%)
The Router DNS Name Resolution latency is still sitting at 0% success though so presuming that's my issue?
thanks
