Sounds like a lot of people are getting stuff wrong - which is hardly surprising as there are people that seem to _enjoy_ getting the technical details wrong. I haven't worked out if it's intentional malace, or they're just fundamentally lazy individuals who just like to screw with other people. Sigh. -- RMK's Patch system: https://www.armlinux.org.uk/developer/patches/ FTTP is here! 80Mbps down 10Mbps up. Decent connectivity at last!
