Hi there,
Anyone experiences a broken wireless connection after the snapshot 20161226 update?
Tumbleweed released snapshot 20161226 yesterday. After the zypper dup --no-allow-vendor-change
update, the NetworkManager could not connect to wireless network, throwing out message of Cannot find IP configuration
or something like that.
Please forgive me that I cannot provide the exactly message it threw out. I am currently using my Android phone to host a USB tethering for this system to look for possible solution. I will update this post to provide more detailed information later after I submitting this post to gain some attentions
In case it helps:
I am using TW with KDE Plasma on a laptop.
dGPU is disabled from BIOS.
Wireless card has following information during boot,
12.716960] rtl8192ce:rtl92ce_read_eeprom_info [rtl8192ce]:<0-0> Chip Version ID: B_CHIP_88C
12.726811] rtl8192ce: Using firmware rtlwifi/rtl8192cfwU.bin
13.102157] ieee80211 phy0: Selected rate control algorithm 'rtl_rc'
13.102373] rtlwifi: rtlwifi: wireless switch is on
13.103467] rtl8192ce 0000:03:00.0 wlp3s0: renamed from wlan0
Wireless connection should be available during boot, but I could not find any information on IPv4.
dmesg | grep IPv4
shows nothing.
Although IPv6 is set to be ignored in NetworkManager, it has some information in dmesg output:
dmesg | grep IPv6

I also remember there is a Reason: 15=4WAY_HANDSHAKE_TIMEOUT
error in dmesg
output when I ask NetworkManager to connect.
Tricks I’ve done to try to bring the wireless network back:
sudo systemctl restart network
sudo systemctl restart NetworkManager
- Delete WiFi configuration and re-create.
- Change WiFi connection from system-wide to current-user-only, and vise versa.
- I lost the chance to try an old working kernel (4.8.14) because I updated to the 4.9.0-2 kernel from update repo. I thought the new 4.9.0-2 kernel could resolve my problem, but it could not. And later, I found I have only 2 kernel versions reserved (I changed
multiversion.kernel
in/etc/zypp/zypp.conf
now).
I am a newbie to Linux DE, but I am eager to learn from solving problems. Any hint is appreciated.
TIA.
