Bruce wants to know how he can secure his WiFi router. Leo says to first enter the router address (198.x.x.x) and then change the default password. Then, turn off Administer via WLan. This will prevent someone from the outside controlling your router. Step 3, turn off UPNP (aka universal plug-in play). This prevents a device inside of your network, like an Xbox, opening up your router to the internet when you don't want it to. Lastly, turn on WPA2 security encryption.

Now that Windows has killed Workgroups, what's the best way to share files for his network? Leo says that file sharing is still available in Windows through File Explorer. But make sure you share with permissions to keep your network secure. What about a NAS? Leo says that a NAS will work, but they can get expensive with having to buy enclosures separate from the drives the data is housed in. 

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:

Bob recently moved south to Tijuana, Mexico, and now his wireless printer won't connect. He's using the same equipment except for his new WiFi router. But still, no luck. Rich says that Bob will need to reset the printer to factory settings and then reset it up with his network to get the new settings. The printer is looking for an address that doesn't exist anymore. So remove the printer and then reboot and add the printer again.

Joe's laptop won't connect to the internet. Leo says that some laptops have a function key that will set your laptop into Airplane mode. So check that out. Other than that, there may have been a corrupted WiFi driver that's preventing the internet from talking to your router/modem. But Joe erased some "unnecessary files" and Windows told him to do it. Leo says that's not the case here. But Microsoft has a tech note about this same issue.

John is going to college soon and he's concerned about Wi-Fi security. Should he have a VPN? Leo says he can. He can find out how open the network is by going into iTunes to see if he can see someone else's iTunes library. If he can, then it's insecure. If he can't, then it's locked down.

Patrick hears Leo talk about Lastpass a lot, but he wants to know if Apple's password vault is secure. Leo says that Apple uses Keychain and it's very secure. It only works on Apple devices, though. And with iOS12, Keychain does autofill.

Jill got a new wireless router and now it's kicking her off the internet, replicating the same problems of her previous router. Leo says that a router dropping the connection from time to time is often a sign of a failing router. Leo advises getting the Asus 3200. Cheap routers are a false economy as they don't perform well, so Jill should spend a little money and get a better router.

Casey has a router with four ports, but he has more printers and computers than that. Leo says to get a router extender that he can plug into one port on the router, which can extend it to handle up to 10 additional ports. Any brand will do. A router switch is a bit more intelligent -- it can switch automatically between them to keep the network running faster. But an extender will work.
