I am simply assuming my modem is on it's way out, strange after 5 years to need rebooting 3 times in a week!
5 years is a long time and I would have thought that there would be a new shiny all singing modem to replace this one but I guess if it just works....
My fibre broadband is fast, really fast. The cabinet is literally across the street, I'm looking at it as I type, there is really no need for me to tweak my settings
