I find it a bit odd that the UK release notes for the v4.4.2 firmware have completely omitted the known issues that the worldwide (i.e. FTP site) release notes show - almost like they're hiding the fact?
These:-
A firewall can restrict/drop unwanted inbound WAN traffic such as VPN requests. The
router's firewall block rules can stop remote management and VPN access. It is
recommended to review the firewall settings before upgrading.
QoS does not work on G.fast line when the link rate exceeds 600 Mbps.
For "ax" series model:
The wireless clients might encounter unexpected trouble (e.g., unable to use the printer on
LAN) while accessing into Internet if the hardware acceleration is enabled.
To skip hardware acceleration for certain devices, the following telnet command can be
used:
ppa -E -e 1
ppa -E -a AA:BB:CC:XX:XX:XX nat|bridge|ipsec
Vigor2866 may have synchronization or performance issues when connecting to the DSL
line with a lower SNR value (<6).
The last one in particular might be of interest to those people who've noticed that they can't sync as fast after upgrading to a 2866 model...
