My MSI Wireless AC905C appears to have ceased to function properly, with the "Your computer appears to be correctly configured, but the device or resource (DNS Server) is not responding" error. I have tried every single fix that I can find, but nothing has resolved the issue. Not even re-installing windows and the device drivers, though after the re-install it did function for about 10 minutes and then the same exact issue arose yet again.
I've managed to get the WiFi to stay connected and function, but it is extremely slow despite the reported speed being above 200 Mbp/s.
I've also just discovered, a few minutes ago that switching from the 5Ghz mode down to 2.4 seems to have allowed it to function somewhat normally, albiet at the slower speeds of 2.4. The card itself supports dual-band, but it seems that dual band is breaking the connection somehow. It has worked fine for a long while, but I am missing one of the antenna that came with the card, perhaps something changed that now requires the other one?
