Lenovo Yoga 13 (Not PRO)

hi there,

been struggling to make my wifi working on a Lenovo Yoga 13.
Already read and tried a couple of options from compiling modules to the kernel and nothing seems to work.

already blacklist the ideapad-laptop module;
running at the moment “on”:
Linux 3.17.1-2.g5c4d099-default #1 SMP Sat Oct 18 23:36:23 UTC 2014 (5c4d099) x86_64 x86_64 x86_64 GNU/Linux

dmesg:
10.290992] rtl8723be 0000:01:00.0: Direct firmware load for rtlwifi/rtl8723befw.bin failed with error -2
10.290998] rtlwifi: Firmware rtlwifi/rtl8723befw.bin not available

Note:
If I enable the ideapad-laptop module I have both hard and sof unblock, however the network manager does not recognize the wifi card.

Thanks in advance for all the support that you might have.
Regards

Hi
So have you installed the kernel-firmware package for your running
kernel?

hi Malcom,

just check my kernel-firmware version and was different from the kernel.
At the moment with the correct kernel-firmware version I have wifi. However not stable. Connect for 2/3minutes and the connections is gone.

any suggestions?
thanks

Hi
Any particular reason for running a 3.17 kernel? Which repo did you install it from?

5

the main reason is/was the reading that this lenovo works better with kernel above 3.15.

The repo is:
http://download.opensuse.org/repositories/Kernel:/stable/standard/

should I try to downgrade the kernel version?
which one do you recommend?

Hi
if all was working fine with the 13.1 default kernel, then I would
stick with that, else it’s probably worth a bug report as a regression
with the later kernel. Maybe user lwfinger sees this and can comment…

I was hoping that this chip, rtl8723be, should work in 13.2, but had the same problem there, connection drops after som time, 20-30 minutes perhaps. I also tried kernel 3.17, but still had the same problem. However google had a solution, create a file /etc/modprobe.d/rtl8723be.conf with the following content options rtl8723be fwlps=0 swlps=0 . I also ran mkinird after having added it, although I dont know if that’s necessary. Probably it would also work with kernel 3.16 in 13.2, but I’ll stick to 3.17 as I got better graphics performance, graphics is Intel HD4600, laptop is a Lenovo B5400 with I5 processor. Support for this chip was first added in kernel 3.15 as far as I remember, so going back to 3.11 won’t work.
WiFi has been stable for about 3 hours right now and with very good performance.
Hopefully it will be fully supported in kernel 3.18.
