Problem Description and Background
Once every second or third page load, my wireless internet connection seems to lag out for about 10-15 seconds and then finally, the page loads. It's making me feel like I'm back in the dial up days with a 56k modem.
I've seen all the known issues with this particular wifi card on the ubuntu community wiki. None of those potential solutions worked for me. For reference: https://wiki.ubuntu.com/HardwareSupport/Machines/Laptops/Dell/XPS/15z
Here is all the relevant debug information, if you require more to assist in troubleshooting, please comment and I will update the question with an answer.
Information
- Dell XPS 15z
