Bob has the Orbi Mesh Router and has a second router for work. Leo says you want one router to be in charge. Leo says your cable ISP wants to be in charge because they use their router to provide WiFi to anyone walking by. Then your work wants to be in charge because it can control everything. In general, you only want one router handling all the DNS address assigning. Leo recommends putting the Orbi in Bridge Mode, and that will prevent both routers from fighting to run the network (called "double natting").
Roger has decided to build his own router as a project using an older computer. What would be the best operating system for it and how should he configure the LAN? Leo says that's a project that Leo has wanted to do for a while now. Steve Gibson has also talked about the DIY router project and uses PF Sense and the NetGate SG1100 with an ARM chip to run it. He likes it a lot and it's open source. It's the way to go. You could also use a Raspberry Pi.
Bob recently bought an eero mesh router. It worked fine for two weeks and then he started experiencing dropouts, and he can't get support. Leo says that support is terrible these days because of limitations due to CoVid. Another thing to look at is your ISP and cable modem. Security software could also be an issue and can inhibit your internet access.
Tom wants to know when he'll be able to get 6Ghz WiFi? Leo said that FCC just approved WiFi 6 as a standard. And WiFi 6 routers are just coming out. WiFi 6 is faster and more reliable too. Leo recommends Ubiquity. But Leo says WiFi 6E routers will be coming by the end of the year, and they'll be able to see through walls and will be great for Mesh routers. And nobody will be on it because it's so new.
Al wants to block all internet traffic coming into his Windows 7 computer so he can use it in his local area network. Leo recommends using the Windows firewall, allowing traffic through 192 for access to your network, and block everything else. You can also do it through the router.
Sharon is getting a lot of buffering using QOS while streaming through her TPLink router. Leo says that while the TPLink is highly recommended, the QOS feature is largely worthless. You may look to see if you can put a third party firmware on it, like DD-WRT or Tomato. It would fix it.
Mike is worried that his WiFi network is compromised since his encryption was bypassed. Leo said that WEP was hacked, and routers went to WPA. And then WPA2. But the latest news is that "Krack attacks" have gotten into WPA2. Leo says it's largely sensationalized headlines and that it's very hard to do and requires a lot of time being on the network itself. Also, by now, most routers have been patched against Krack. So it's not really anything to fret over. And WPA3 is on the horizon, with new routers turning it on with a software upgrade.
Here are some things you can do:
Stan wants to get a better router for coverage in his home. Leo recommends a mesh router with WiFi 6. Leo likes Orbi by NetGear, but he recommends checking out the Wirecutter for their recommendations. Leo also recommends the Aero, which is a good one too.
Sam looked in the settings of his Netgear Orbi router and made a few changes. Now, many things he uses on his network don't work any longer. Leo suggests powering down the router, count to 30, and then power it back up. If that doesn't work, you can completely reset the router. There's a reset hole that you poke a paperclip into and hold it until the lights blink yellow. You'll need to reset it up and give it a new password, but it will be back to the factory settings. Also turn off WAN administration, and universal Plug n Play (UPnP). You'll be back up and running.
Tom's router has four ethernet ports. Should he use them to install multiple hubs with switches or multiple switches? Leo says that switches aren't very smart on the whole, and switches are really just another name for hubs. What he needs is a smart switch to really isolate the traffic and maximize speed. Leo has a 24-port switch connected to his Orbi router and he uses that to connect all his devices that need a wired connection. That includes his streaming box and TV.
