Network isolation
/I hate it when hardware manufacturers spoil their products by skimping on one, crucial component. Take NetGear for example. They make quite good network hardware, but then they add the cheapest possible power supplies they can find. This means (for me at least) that every few years I have to buy a new 12 volt power supply to replace the one that just went pop.
I’ve just had to do it again. One of the routers in my network failed. The good news is that when this happens my eero network converts one of the Wi-Fi repeaters into a network receiver and so the network keeps going - just a lot slower than it used to. It can take me a while to discover that the network is broken in this way, I usually discover things are not right when I have to do an update to Microsoft Flight Simulator.
