My house is less than 10 years old. The standard builders package included a cat5 run to every room, but I paid extra for them to do cat6 instead.
After upgrading my internet service a year or so ago, I had been experiencing random disconnects and link speed slowdowns to my desktop PC in my basement office area.
Today I traced all the wires in the house. The electrician installed cat6 everywhere, except two runs were cat5. Guess where one of them was?
