I followed the instructions at this post:

My wireless/WiFi connection does not work. What information is needed to diagnose the issue?

and posted a specific question about intermittent (but consistent) slowness running Ubuntu on a Lenovo Yoga 2 Ideapad:

Why are wireless networks that work for other people super slow on my Lenovo Yoga?

Which now has a vote to close because it is too broad. I'm stumped. I encouraged someone to buy a Lenovo and install Ubuntu on it, which she did, and now she has the worlds crappiest internet connection and I want to help her make it work. I'm used to using Ask Ubuntu to help me make things work. What is the right way to ask for help troubleshooting a wireless problem in Ubuntu?
