[Bug 1444766] Re: Wifi connection issues
Marvin Scholz, as per http://support.lenovo.com/us/en/products/laptops-
and-netbooks/thinkpad-x-series-laptops/thinkpad-x250 an update to your
computer's buggy and outdated BIOS is available (1.07). If you update to
this following https://help.ubuntu.com/community/BIOSUpdate does it
change anything?
If it doesn't, could you please both specify what happened, and provide the output of the following terminal command:
sudo dmidecode -s bios-version && sudo dmidecode -s bios-release-date
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. As well, you don't
have to create a new bug report.
Once the BIOS is updated, and the information above is provided, then
please mark this report Status Confirmed.
Thank you for your understanding.

Title:
Wifi connection issues
Status in linux package in Ubuntu:
Incomplete
Bug description:
1) Ubuntu Version: 15.04 (Vivid Vervet)
2) Kernel Version: 3.19.0-12-generic
Wireless: Intel Wireless 7265 (on Thinkpad X250)
3) I expect Wifi to work as expected without connection drops.
4) I am experiencing sudden connection drops, which means I am not
able to connect to anything after a certain time and it seems that it
only happens after certain amount of data has be downloaded. Although
the Wifi still appears as connected, it behaves like it isn't.
Other:
When I am booting with Kernel 3.16.0-23-generic I do not experience any Wifi connection problems at all.
(I am not sure if this bugreport is fine, as this is the first time I am reporting a bug here, I will be happy to do improvements to the report if I did anything wrong or provide as much data as possible upon request.)
