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.
Charles got a new Eero mesh router all set up (Eero is a sponsor of the TWiT Network), but now he gets a warning that his router can be seen online. Leo says that the best thing a router can do is be invisible by not responding to any online queries. It's called Stealth Mode. That's what GRC's Shields Up will test. Most routers have PING turn on by default. But you can turn it off in the security settings. Also, turn off universal plug n play and file sharing.
Andrew has Verizon FIOS and wants to know if he can use his own router. Leo says that Verizon bundles the router/modem together. Leo says you won't save any money since you have to use Verizon's modem/router anyway. But if you want to do your own router, you can turn off HDCP in the Verizon router and then use your own router for a better experience.

Jack's mom is moving into an assisted living facility, and he wants her to have her own WiFi. What router should he get her? Leo says it's a good idea to give her own WiFi access point. It'll protect her. NetGear makes great WiFi Routers. How about a basic wireless access point? Leo says that the router will be better for security, but a WAC is fine.
Should he get a Samsung Galaxy Note 10? Leo says that since Jack has a note 8, he can trade it in and get a great deal on a Note 10. Go for it.
Joe has switched his parents over to Comcast for internet access and TV, and he's having a hard time opening ports through the router for their alarm system. What can he do? Rich says to try what Xfinity recommends here - https://www.xfinity.com/support/articles/port-forwarding-xfinity-wireless-gateway. If that doesn't work, then it may be that the port forwarding capability of Xfinity is limited. Rich also says to make sure the firmware is updated.
Karen had her power shut off recently due to the wildfires and now she can't connect to her network via WiFi. Rich says this is common and can happen when turning things back on. If she doesn't reboot both in the right order, she won't be able to connect. So Rich recommends turning them off again and unplugging them. Then plug in the modem, and the router afterward.
