Fresh install and the wifi configuration seems to be detecting a bunch of devices, just not my router, which it's right next to. I tried setting it up as a hidden device, it could not connect. My phone can use the wifi fine, so the signal is strong theoretically. I also looked up the firmware vs adapter in my laptop in this list, it's a Intel Centrino Advanced-N 6235. The firmware for it seems right. And it's not dysfunctional, it just seems to not want to see my router specifically, for seemingly no reason.
Any suggestions as to what I should try to fix it?
