It is working on 5G from around 3am, before that I am on 4G for stability for lower latency and packet loss.
They send me this one as where I live is problematic due to physical signal blockage with high buildings and I have tons of masts around me apparently.
So far, besides a snappier interface - I guess due to better hardware - a few changes in the interface, deactivated the auto-update to not loose this firmware that enables me activate other options that might get blocked later by update.
Under the rounter the sticker comes with user as "user" and a random password.
Here are some screenshots of options I have noticed different from the 801, which I don' think needed any repalcement by they insisted in giving a go since my specific location is very troubled, even they suggest me to cancel the service due to signal blockage and apparenty there is infraestructure maintenance that antecipates finish works for around November, they suggest also to me to keep calling them in order to have discount giving my situation. I don;t really have any other option, other than tether my phone via USB (GiffGaff/O2) on 4G and works much better.
(for reference as mentioned to me, is not about bandwidth but QoS, ping and ping variation, drop packets etc.)
Honestly I can't wait to move out of this place when the contract ends. This makes miss ADSL times.
On the login screen you can see:
On the main page quick bar is more limited I guess due to user I am using but I havent found a higher permission user, if you know I appreciate:

(Now I have the mc801 for nothing. Ask them what to do with it to which they said to keep it...just have no usage for it right at this point...)
