Hello,
Sorry for the new post, but I found the last similar one from 2014, and 5 years in technology is an abyss.
I also have internet with 60 Mb / s multimedia
I got ARRIS-237A from multimedia.
And there is a tragedy in general
60-70% of the time, the internet works fine, but there are times when you need to use LTE on the phone.
The service has been called up many times.
The service technician claims that I have to use their equipment, and only then possibly let a modem follow him - I used to do that and it did not work.
I would like to add that it is cable internet (i.e. not RJ45 but a signal cable).
Gentlemen, what to buy to really work out and not fail?
Budget doesn't matter.
