I have three computers: an old iMac with High Sierra, a laptop with Windows 10, and a Windows 7 desktop
Problem: The desktop internet connection is dropping out or incredibly slow, not matter what browser is used. This began as soon as the NBN was connected and the new Sagecom hardware installed.
NB: I checked the seetings in the Sagecom admin panel and from what I understand, I think it is acting as a modem, and not a router. I don't think this can be changed.
I haven't heard that it's incompatible with Windows 7. @Jeneral__Pain might be able to offer some further help?
