Trevor has a Netgear modem connected to his Google OnHub router. Everything works fine except for an old laptop. Can he connect hardwired to a repeater? Leo says that a second Google device would work because they have two ethernet ports.
What about buffer bloat? Is that still a thing? Leo said it used to be. It happened when RAM in routers got cheap and more RAM was added, which caused issues with TCP/iP on large buffer routers, slowing down the internet. To check for it, Trevor can try running the online test Netalyzr. There's also SpeedTest.Net and testmy.net.
