[Bug 1590985] Re: Wifi non-functional after suspend (Intel 6205)
James Ferguson, as per http://support.lenovo.com/us/en/products/Laptops-
and-netbooks/ThinkPad-X-Series-
laptops/ThinkPad-X230?linkTrack=GPS%253ABody_Search%2BProducts&tabName=&beta=false
an update to your computer's buggy, insecure, and outdated BIOS is
available (2.66). When you update to this following
https://help.ubuntu.com/community/BIOSUpdate how does this improve the
situation?
For more on BIOS updates and linux, please see
https://help.ubuntu.com/community/ReportingBugs#Bug_reporting_etiquette
.
Please note your current BIOS is already in the Bug Description, so
posting this on the old BIOS would not be helpful.
Also, you don't have to create a new bug report.
Once the BIOS is updated, if the problem is still reproducible:
1) Please provide the output of the following terminal command (not perform an apport-collect):
sudo dmidecode -s bios-version && sudo dmidecode -s bios-release-date
2) Please make a comment specifically advising on if there was an improvement or not.
3) Please mark this report Status Confirmed.
If it's not reproducible, please mark this as Invalid.
Thank you for your help.
** Changed in: linux (Ubuntu)

Title:
Wifi non-functional after suspend (Intel 6205)
Status in linux package in Ubuntu:
Incomplete
Bug description:
Often, but not always, on resume from suspend my wifi does not
connect. In the networking tray drop-down I can see one single wifi
network listed (out of the many within range), and it can't reconnect
to my network.
I clear it with the hammer of:
sudo rmmod iwldvm && sudo modprobe iwldvm
I'm not sure what would be more appropriate, but that works. Then my
laptop auto-connects to the right network, as expected.
Turning on/off the hardware wireless switch on the thinkpad does not
clear the problem.
Just before running ubuntu-bug to submit this, I had the problem, then
reloaded the iwldvm module.
