I have a Lenovo 300e Gen 2 AST. it works fine except Touchscreen issues but I don’t care about those, I don’t use Touchscreen. My problem is that it won’t connect to 5-GHz networks, my network used to be dual-band but its 5-GHz only now and my Chromebook won’t connect. I really need my Chromebook for some important stuff so please tell me a fix, if any, ASAP.
