Tech Tip Tuesday: Set Up a Guest Wi-Fi Network Before the Holiday Company Shows Up
The holidays are coming, and you know the first thing somebody's going to ask when they walk in the door. "What's the Wi-Fi password?"
Most of us just read off the same password we've had for years. The problem is, that password gets into everything in the house: your computers, your printer, your cameras, your doorbell. Once a phone or tablet is on that network, it can see all of it. I'm not saying your family is up to anything. But you have no idea what's on your nephew's six-year-old tablet, and let's be honest, nobody remembers to change the password after everyone goes home.
That's where a guest network comes in. Most routers from the last several years can do it, and it only takes about ten minutes.
What it is
A guest network is a second Wi-Fi network that your router puts out alongside your main one. It gets its own name and its own password. People on it can use the internet, but they can't see anything on your main network.
Why I like it
• Guests get online and you don't have to give out your main password.
• If somebody's phone or tablet has a virus on it, it stays on the guest side, away from your computers.
• You can change the guest password whenever you want without reconnecting everything you own.
• It's also a good spot for those cheap smart plugs and gadgets you're not so sure about.
One heads-up: Some things need to be on the same network as your phone to work, like a Chromecast, a printer you print to from your phone, or a smart speaker you control with an app. Leave those on your main network. Otherwise your phone won't be able to find them and you'll be wondering why.
How to set it up
If your router has an app (eero, Google Nest Wifi, Netgear Orbi or Nighthawk, TP-Link Deco, and most of the newer mesh systems):
1. Open the app and look for "Guest Network" or "Guest Wi-Fi." It's usually under Settings or Network.
2. Turn it on and name it something you'll recognize, like "Smith-Guest."
3. Give it a different password than your main network.
4. Save it. A lot of these apps will show you a QR code too. Print it out and stick it on the fridge, and guests can just scan it with their phone.
If you don't have an app:
1. On a computer that's on your Wi-Fi, type your router's address into the web browser. It's usually 192.168.1.1 or 192.168.0.1, or check the sticker on the router.
2. Log in with the admin username and password. That's usually on the sticker too.
3. Find the Wireless or Guest Network section and turn the guest network on.
4. Give it a name and a password, and make sure security is set to WPA2 or WPA3.
5. If you see a setting like "Allow guests to access my local network," make sure it's turned OFF.
6. Save, and you're done.
Pro tip: After the holidays, change the guest password. Anybody who saved it on their phone this year is off your network, and next year everyone gets a new one.
If your router doesn't have a guest network option at all, it's probably getting up there in age. That's worth a look anyway, especially if you've been dealing with buffering or spots in the house where the Wi-Fi drops.
If you'd rather not mess with router settings, I'm happy to take care of it. I'll set up the guest network, put your smart devices where they belong, and make sure everything in the house is locked down. I'll come right to your home or office.
