Red Hat Bugzilla – Bug 1295272
Wi-Fi not working on Lenovo Yoga 700
Last modified: 2016-01-26 13:24:25 EST
Description of problem:
When the `ideapad-laptop` driver is loaded the Wi-Fi interface of my Lenovo Yoga 700 is marked as hardware switch disabled even though it does not have a hardware switch. As soon as this driver is unloaded Wi-Fi works again, however e.g. the touchscreen stops working.
This is probably a similar problem as described in bug 1021036.
Version-Release number of selected component (if applicable):
Steps to Reproduce:
1. Run Fedora 23 on Lenovo Yoga 700
2. Try to use Wi-Fi (won't work)
3. `sudo modprobe -r ideapad-laptop`
4. Try to use Wi-Fi (will work)
Wi-Fi doesn't work when ideapad-laptop is loaded
Wi-Fi always works
Output of `sudo dmidecode | grep 'System Information' -A8`:
[liveuser@localhost ~]$ sudo dmidecode | grep 'System Information' -A8
Product Name: 80QD
Version: Lenovo YOGA 700-14ISK
Serial Number: PF0DYTRT
Wake-up Type: Power Switch
SKU Number: LENOVO_MT_80QD_BU_idea_FM_Lenovo YOGA 700-14ISK
Correction: The touchscreen actually continues working after unloading the module, this seems to have been a glitch somewhere else. However the airplane mode key stops working after unloading the module.
This sounds like another variant of bug 1286293. Sigh.
Can you attach the output of dmidecode when run as root?

Thank you. I'll hopefully have a build for you to test tomorrow.
Please test this scratch build when it completes:
Have you had a chance to test this? I would like to send the patch upstream after getting confirmation if it works.
Sorry, I'm away from that laptop until the weekend. I'll report back about it then.
This works with your patch. Thanks for the effort!
