Z490 Taichi WiFi and Windows update

Message Topic Search Topic Options Post Reply Create New Topic Printable Version Translate Topic

   Hello,

I recently completed a build with a Z490 Taichi and all was well until I updated Windows to 20H2. My wifi slowed down to a crawl. like 10Mbps at best. I tried a number of things but ultimately had to revert the update to Windows 1909. The problem however is that I can't enable ray tracing without a more recent Windows 10 build. So I would like to be able to update the OS but I can't have my wifi be that slow. Is there a known issue with this MOBO and Windows 10 20H2? Please advise as if I dropped a good amount of cash on this build expecting to be able to push all the latest tech with the GPU. Thanks!

	Dear Hawkhandler, Thanks for posting to the ASRock forum. We have checked, when connected to the 5GHz band of the router, it can run up to 95Mbps without problems on Win10 20H2. Please check the followings: 1. The following WiFi driver is installed. https://download.asrock.com/Drivers/Intel/WLAN/Intel_WLAN(v21.80.0.4).zip 2. Make sure that the WiFi is connected to the 5G band of your router. 3. Check if the WiFi dongles are in a good form. 4. Check the speed of the router to see if the router is working properly by using a different device. With thanks, ASRock TSD Edited by ASRock_TSD - 28 Dec 2020 at 4:47pm
