In my last post I was a confussled mess, failing to get my head around how a network device (The Raspberry Pi) could cripple an exclusive function of my router.
I decided to troubleshoot the issue further, I set up a basic ping to help me pinpoint when the internet was going down
After performing some basic troubleshooting, it transpired that the fault was happening whenever the HDMI cable was connected to the Pi and my Television (Sony Bravia EX4-32).
Thinking it was a bad HDMI cable, I bought another, but to no avail. My next brainwave was that the Pi was emitting EMI (or RFI) which drove me to buy a 10 metre HDMI cable to get the Pi as far away from my router and other networking equipment, alas this didn’t work either.
Troubleshooting further, it turned out that the HDMI cable didn’t need to be properly connected, mealy touching the Pi on any metallic part will cause the internet to cease.
So in essence I am still no closer to solving my Pi/Internet mystery, if you can help me please comment!
All other HDMI works fine as I am now using the 10m HDMI cable as a screen extender on my laptop.
Bootnote:
In my previous post I signed off by stating that that the Pi and my internet were working in harmony. However it turned out that my modem had dialled back my downstream internet speed to 1.5Mbps instead of the usual 3Mbps, normally a result of the modem trying to obtain a more stable internet connection due to, lets say, interference on the line!
