Considerations:

 - Bugs are still offtopic here.
 - List type questions and answers are a bad fit and actually against the site scope (per Help Center).
 - Dupe voting works fine to ID duplicates.

Also, consider the [Canonical "wifi not working" question proposal here on meta][1].

 - If we have the same workarounds for an NVIDIA card then we could have one master question for NVIDIA, but given there are a ton of NVIDIA cards that is not feasible.
 - Same applies for AMD cards, wifi cards from multiple manufacturers, Ethernet cards from multiple manufacturers, etc.

We can't create a master post for those or linking to the masters because we end up with either a billion pages of support answers or an unending list.  It's not feasible.
