This is more likely to be a driver issue than management issue.
I think, this was posted to HN before, but I cannot find the article right now, but the gist of it is: both WiFi h/w vendors and Linux driver authors are to blame for the dismal state of events. On the h/w vendor side everything as per usual: no drivers, or broken drivers, incorrect product labeling or self-identification, false or imprecise advertisement of available features. On Linux side: slow inclusion of community-provided drivers for various WiFi modems, no real effort at cataloging and unification / systematization of available drivers.
My experience so far is this: Intel h/w is the one that has best Linux support. So, if you are on Realtec or Mediatec, you are getting the short end of the stick.
Another universal problem: WiFi protocol keeps iterating at a relatively high speed. Which means that you are often in a situation where either your modem or your router don't speak the same protocol at a good level, and the middle-ground that they find is not well-supported or, sometimes will only be found after lengthy unsuccessful attempts by both sides to do the handshake. This is often also exacerbated by the management software which may misidentify these "handshake problems" and "solve" them by restarting something in the network stack, essentially sending you into an infinite loop of trying to connect.
In my unfortunate case with my latest PC build, I had to swap three WiFi modems before I found one that worked satisfactory with the router I have. So, if you have some extra $ to throw at your problem: maybe try getting another WiFi modem?
