[Solved] Wireless won't connect on kernel 5.1.x

lervag · 2019-05-20 21:54:53

I'm having trouble connecting my wifi after updating to kernel 5.1.x. Downgrading fixes things, but is not a proper solution.

I'm on a Thinkpad X1 G6, and I use netctl-auto to handle connections. Below I have attached output of lspci and what seems to be the relevant parts of the error messages in the log.

Any help would be very much appreciated!

> lspci -v
02:00.0 Network controller: Intel Corporation Wireless 8265 / 8275 (rev 78)
	Subsystem: Intel Corporation Dual Band Wireless-AC 8265
	Flags: bus master, fast devsel, latency 0, IRQ 134
	Memory at e0300000 (64-bit, non-prefetchable) [size=8K]
	Capabilities: <access denied>
	Kernel driver in use: iwlwifi
	Kernel modules: iwlwifi

Below are some exerpts of the output of "sudo journalctl -xe" that seems relevant. First, the part related directly to "netctl-auto" and what seems to be the error message from the kernel:

Rather than dump the entire journal, connect manually and paste the exact commands and output/errors when the connection fails...

Moving to NC.

lervag · 2019-05-21 06:18:43

@jasonwryan I'm sorry for not taking more time in my initial posting. I've updated now. I think this belongs in the Kernel and Hardware section, not NC. If you think I'm wrong, please let me know why.

jasonwryan · 2019-05-21 06:47:08

It belongs in NC. Please act on my initial request and connect manually; it is the most effective way to debug wireless issues.

lervag · 2019-05-22 19:57:06

Thanks! I disabled the netctl-auto service, then rebooted and connected manually. This worked. With netctl-auto enabled, it did not work, but I was now able to find some more info, e.g.

> ip link set wlp2s0 up
RTNETLINK answers: Input/output error

I searched for more information on this, and did not find anything directly relevant. I don't have conflicting services. But with some time, I found that I had the following module options for iwlwifi:

options iwlwifi power_save=1 d0i3_disable=0 uapsd_disable=0

I added these when installing based on some suggestions for how to tune power saving on the Thinkpad X1 Carbon. If I remove these options, then everything works as expected.

I would be very happy to learn more about what may have been wrong, but I'm also just happy to have things working.

Again, thanks. Your pointer on connecting manually was key to finding relevant search terms for finding a solution.

You can read about the parameters here: https://www.kernel.org/doc/html/v4.14/a … eters.html

Glad you got it sorted. Please remember to mark your thread as [Solved] by editing your first post and prepending it to the title.
