I followed the instructions at this post:

https://askubuntu.com/questions/425155/my-wireless-wifi-connection-does-not-work-what-information-is-needed-to-diagnos/425205#425205

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

https://askubuntu.com/questions/488127/why-are-wireless-networks-that-work-for-other-people-super-slow-on-my-lenovo-yog 

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?
