[Kernel-packages] [Bug 1324095] Re: [Lenovo Yoga 2 Pro] ideapad_laptop kernel module breaks wireless
I also USED to run (L)ubuntu 14.04 on a Yoga 2 pro 13, but after an upgrade (around the middle of June, 2014), I lost the ability to connect to WiFi. When I tried to re-install Lubuntu from a USB with an ISO on it, it failed to connect to the WiFi, and claims that the WiFi is Harware blocked, even though there are no switches or function keys to block the WiFi hardwarely. This ideapa_laptop module has been a pain from the first day with the (otherwise very nice) Yoga 2 Pro. WHEN IS THERE GOING TO BE A VERSION OF (L)ubuntu which will be installable without bug-avoiding tweaking like compiling patches, etc.? Should I wait for 14.10?

[Kernel-packages] [Bug 1324095] Re: [Lenovo Yoga 2 Pro] ideapad_laptop kernel module breaks wireless
Additionally, the latest release of the ubuntu kernel that has the fix
for this, won't actually fix it for all of the systems.
The error is here:
+/* Blacklist for devices where the ideapad rfkill interface does not work */
+static struct dmi_system_id rfkill_blacklist[] = {
+ /* The Lenovo Yoga 2 11 always reports everything as blocked */
+ {
+ .ident = Lenovo Yoga 2 11,
+ .matches = {
+ DMI_MATCH(DMI_SYS_VENDOR, LENOVO),
+ DMI_MATCH(DMI_PRODUCT_VERSION, Lenovo Yoga 2 11),
+ },
+ },
+ {}
+};
This patch will only solve the problem for the Lenovo Yoga 2 11, not the
Yoga 2 pro 13's which report with Lenovo Yoga 2.
The patch should be updated to reflect this by adding:
DMI_MATCH(DMI_PRODUCT_VERSION, Lenovo Yoga 2)
