Glad to see some activity on this problem.

It’s a long thread, so I’ll summarize some of the highlighrts for people newly joining the discussion.

  • I started out writh 3.012 and upgraded to 3.025. Both showed the problem.

  • I would not be surprised if any version 2.x worked. The GL-iNet literature says that there’s a new driver in the v2 product (presumably in the 3.x software.) The problem is almost surely in the MT300N-v2’s driver software.

  • The problem is that the MT300N-v2 is NOT proceeding to start the 4-way handshake needed to enable encryption following an Association Request packet form the Chromebook. The failure to start (or complete) the handshake is causing the Chromebook to keep sending Association Requests and eventually to timeout and display an error.

  • The bunch of Chromebooks which worked seem to have a different wifi chipset than the ones which don’t. Thank you sfx2000 for instructions on how to identify the chipset. Alas, I’m across the country for the next month and don’t have access to the failing Chromebook. If Black Friday weren’t coming up, I’d go back to Best Buy and would look this up in one of the other failing models. (See post #37 above here.)

    The Associate Request is slightly different in the models which do connect from those that do not. The difference is probably what is driving the MT300N-v2 not to start the handshake, eventually leading to a timeout.

  • Since these Chromebooks connect without problem to other routers (including other GL-iNet models), any correction really should come from GL-iNet and not the provider of the Chromebook driver. Regardless, I got no response when I submitted multiple problem reports to Google or Acer.

  • Until the tech staff gets their hands on a model which shows this problem, I understand it’ll be difficult to debug.

I would ask if GL-iNet is willing to take trace (pcap) files previously submitted and replay-them to the router. If so, we would have the ability to push Association Requests to the router without needing to have one of these Chromebook models. There are a number of tools available for this: airreplay-ng (here) or tcpreplay (here).
