adrenalin1982 Posted January 11, 2018 Share Posted January 11, 2018 Hello everybody, I am looking for a solution to get my 5 ghz wlan network up and running. I notice that under Windows 10 or previous yosemite installation everything worked fine. Now I switched to high sierra. WLAN works perfectly in the 2.4 GHZ band. Bluetooth works well, too. Does anyone have similar experiences with the same Broadcom network card? I am happy about any help! Best Regards Link to comment Share on other sites More sharing options...
Dwarfy Posted January 11, 2018 Share Posted January 11, 2018 Hi, Got Apple BCM94360CD here as well. Using 5Ghz and I rely a lot on BT, so I use it a lot. Been using this card for some years now.Everything works perfectly even on 10.13.2. I didn't get what exact issue you are facing. If you could be a bit more clear, please.

Gigamaxx Posted January 12, 2018 Share Posted January 12, 2018 Mine works as well, maybe its a router issue too many other devices using the 5.0GHz channel. Link to comment Share on other sites More sharing options...
adrenalin1982 Posted January 13, 2018 Author Share Posted January 13, 2018 Same here; 'have been running most of my laptop Hackintoshes on Apple's BCM94360CD for nearly 3 years. As expected, they work 100% OOB (BT + 2.4GHz + 5GHz) with all recent versions, from El Capitan to latest High Sierra. I just had to change the 5GHz channel on my wireless router. I can not believe it. The tip with the channel change on the wireless router is the solution. And that although it worked smoothly with yosemite before without channel change Thanks to everyone involved. Link to comment Share on other sites More sharing options...
adrenalin1982 Posted January 14, 2018 Author Share Posted January 14, 2018 Unfortunately wlan does not work after waking up. 2,4 GHZ yes but at 5 GHZ remains inactive. Only when I restart the computer completely, then also the 5 ghz network works. Is there a fix for this problem?My motherboard is: Gigabyte GA-Z97X-UD5H-BKLooking forward to your answers.

adrenalin1982 Posted January 15, 2018 Author Share Posted January 15, 2018 I found the solution for the problem after sleep. you have to untick the " wake for network access" in energy saver. Now the wifi adapter still works flawless under 5 ghz after awake. Link to comment Share on other sites More sharing options...
