I know this chipset is supported, and I did read through a few wifi threads, but I saw no mention of wifi working then not other than a mention in the wifi testers thread.
During install wifi is fine. using it after install it is fine. I recently updated and now wifi no longer works. It no longer shows up under Network nor ifconfig. Running Hiaku on a Lenovo x240, Intel i5-4300U, 8GB RAM, 64bit Haiku build. Hardlined Intel Pro1000 works fine.
