If I install the Plusnet branded version 184.108.40.206 which I can download from their web site:
a) Will I loose any capability?
b) Can I re-install 220.127.116.11?
c) Will the router be locked to Plusnet in any way?
d) Is there any other reason why I might regret doing this?
My main reason for applying the upgrade is that the router occasionally starts to refuse (or continue to allow) wired connections, and has to be rebooted.
Sadly I can't find any suitaboe firmware on the Thomson/Technicolor web site.
