Extending your Apple Watch with WiFi

WiFi on Apple Watch!?

It’s not completely obvious but the Apple Watch supports WiFi networks starting in Watch OS 2.0. How does one configure WiFi to work with the Watch? It’s not terribly obvious so I threw this guide together.

My Situation

My Apple Watch was not configured to work with WiFi. I have both 5GHz and 2.4GHz networks in my home. I normally do not join the 2.4GHz network because it doesn’t work as well as the 5GHz. I looked at the Apple Support page on WiFi for the Apple Watch and realized my situation. Apple Watch only supports 2.4GHz networks.

DOH!

The solution for me was to join the 2.4GHz network so the iPhone knows the password. Those credentials are then shared automatically with the Apple Watch.

The Process

Step 1 – Join a 2.4GHz network. In my case, sourapple. I normally use sourapple 5GHz. FBI Surveillance Van is the WiFi in my garden shed but it’s at 5GHz. I’m disappointed that my Apple Watch won’t work with my WiFi when I’m out in the yard without my phone.

Step 2 – Give the iPhone a few moments to do whatever magic it needs to do to copy the new credentials to the Apple Watch. I ended up just launching the Watch app on my iPhone and poked around for a bit. This step may not be necessary.

Step 3 – Bring up the settings glance on your Watch.

Step 4 – Turn off Bluetooth on your iPhone.

Step 5 – See the icon of the iPhone turn into a cloud on your Watch.

What’s the Big Deal

Turning on WiFi support means you can put greater distance between you and your iPhone and your Watch will still have connectivity. The downside is that WiFi uses more energy than bluetooth and it’ll impact your battery life.

Why I Use VPN on My Mobile Devices

I’m not terribly paranoid about online security compared to some. I do take some extra precautions when doing things online that involves financial data and logging into accounts.  Here are a few rules I follow internally when out and about:

  • Public WiFi should only be used when cellular data isn’t sufficient or available
  • Always ask what the SSID (network name) is when using public WiFi at a coffee shop – don’t assume you’ve picked the right one
  • Never ever do anything with financial information (banks, credit cards including purchases)
  • Never create new accounts over public WiFi
  • Wired and “protected” WiFi at hotels is just as unsafe as public WiFi
  • Use a VPN (virtual private network) to a trusted destination when using a public Internet connection
  • Secure your home WiFi with a strong password and WPA2-PSK encryption

A virtual private network connection lets you create a safe connection from where you are to where the VPN server resides.  Depending on the VPN configuration it may allow you to go back out to the Internet from there or you may be limited to local connections only on the server side.  In the case of how I use VPN, I connect to a home server which effectively makes someone in the coffee shop I’m at unable to see my online activity.

I have a Mac mini running Mac OS X Mavericks + Server at home – it actually is the machine I use in my entertainment stand for movies and recording TV off the air.  I have the VPN service turned on so that when I am out of my home I can tunnel through to home and back out onto the Internet.  VPN can be configured on most mobile devices (Android and iOS) and laptops (Windows, Mac and Linux).  It does require some technical knowledge to do this.

There are also apps you can purchase for your mobile device to give you a VPN connection.  The problem I have with these services is you have no idea what’s happening on the server side.  If the point of using VPN is to prevent eavesdroppers from seeing your secure data then you have to be able to trust the entire connection.  VPN does provide a false sense of security in the sense that it’s not securing the entire conversation.  VPN is only secure up to the end point (server).  If someone has access to that server, there is a chance they can snoop on your activity.

In the end, just be careful what you’re doing online in public areas.  Cellular data is certainly more secure than public WiFi but it’s still susceptible to snooping.  There is a fine line between paranoia and convenience so you’ll just want to determine where that line lies for yourself.
