For the last week or so, the downstream speed of my HH6 has been steadily increasing from about 72 Mbps to 80.
However, with the increase in speed, IPv6 is no longer working.
Just a coincidence?
Hub IPv6 status: EnabledIPv6 network status: Disabled
The Smarthub does have a glitch where if the line re-syncs it often doesn't get a new IPv6 address, but does if the smarthub is re-booted.
My smarthub re-boots every 14 days, so I didn't have to wait too long after the speed increase I got from being on 3dB for me to get IPv6 back again.
