Ad-Blocking On The Go

After a recent trip away and having to endure the torrent of adverts and tracking that hotel WiFi and mobile internet connections provide, I was definitely missing the ad-blocking features of my Raspberry Pi running Pi-Hole back at home.

I’d also been thinking for a while that I should do something about securing my phone a little bit from the risks associated with using an unencrypted WiFi connection like the one available to me at work. Using insecure WiFi is a bad idea because anyone else on the same network can examine your traffic and potentially log in to all your internet accounts by stealing session cookies and account details.

So, I decided to add PiVPN to my Raspberry Pi and Pi-Hole setup. Now when I’m away from home, my phone encrypts all of its traffic using WireGuard and sends it back home to my Rasberry Pi. Here, all the usual blocking of adverts and trackers happens and I get the same nice experience out and about as I do at home. There’s also the added peace of mind that means nobody on an insecure WiFi link can see the traffic between my phone and the internet any more – everything is encrypted on its way back to my house. Lovely.

PiVPN was a breeze to set up. It took just seconds to install and set it up, and adding the phone’s connection was as simple as pointing my phone at a QR code. Amazing work by the community.

Fighting Back Against Internet Advertisements

I’m old enough to remember the World Wide Web in its infancy in the early 1990s, when the focus was on information sharing. These days the main aim of the web seems to be to make money by tracking people’s habits and showing them adverts.

I missed the old experience, and I wanted some protection against being tracked everywhere online, so I installed Pi-Hole on a Raspberry Pi and tucked it away behind the sofa. It was very easy to set up, and has worked perfectly for over a year, protecting all of our devices from the spying panopticon of advertisers.

I have genuinely been surprised at just how much of modern internet traffic is related to tracking and adverts. In fact, my Pi-Hole has blocked more than half of the total requests for data! That’s right – there’s more stuff flying around for the adverts and trackers rather than the actual content that you see. Crazy.

With Pi-Hole blocking things silently, you end up with cleaner web pages without the clutter of adverts, and pages load noticeably faster when they aren’t reporting back to big brother too. Mobile apps and games no longer show annoying full-screen adverts and things just work much much better.

In fact, Pi-Hole blocking has been so good that as soon as I go out and about away from my home network it is very jarring to see the internet as everyone else sees it. Full of adverts and junk. Yuck. I do have a plan to fix that little problem soon though…
