Re: Replace WiFi card in E485

You don't need to specify amdgpu.dc=1 for any Vega GPU. It's always enabled for Vega and won't even work without display core (dc). Why are you disabling amdgpu.aspm by the way?


ivrs_ioapic[32]=00:14.0 ivrs_ioapic[33]=00:00.1

Is that the key part which fixes blutooth? Sounds like something Lenovo need to fix in the UEFI.

Re: Replace WiFi card in E485

Maybe amdgpu.dc=1 is not necessary now since it's enabled by default in the newest kernels.

The parameters ivrs_ioapic[32]=00:14.0 ivrs_ioapic[33]=00:00.1 are needed to make the screen (or perhaps the GPU or perhaps X) and the SD card reader work. They aren't the key part to fix Bluetooth.

I only posted the settings that work in my computer which I found out reading here and there and by trial and error.

And yes, the UEFI must be fixed. It's stated and proven in this forum topic.

Re: Replace WiFi card in E485

Hi all


For those with intel bluetooth issues, i have posted a thread over at intel raising the issue.

It might be good if you could add to the conversation as it might be fixed alot quicker.

Re: Replace WiFi card in E485

Hi there,


I have replaced my WiFi with a 9260 as well. But my throughput is really bad. Only 20-30MByte/s from a fileserver and the same throughput checked with netio. The network connection says 866MBit and I am just 2m away from my router. My wife gets around 60-70MByte/s with her older Clevo notebook and a 7260 card.


Has anybody else these issues or some tips how to increase these values? I am on Windows 10 pro btw and have already doublechecked the antenna connectors.


Theoretically both the 9260 and my router support 160MHz bandwith which should result in 1,73Gbit. But the 9260 is only using 80MHz.
