Marvin Scholz, the next step is to fully commit bisect from kernel 3.16 to 3.19 in order to identify the last good kernel commit, followed immediately by the first bad one. This will allow for a more expedited analysis of the root cause of your issue. Could you please do this following https://wiki.ubuntu.com/Kernel/KernelBisection ?
Please note, finding adjacent kernel versions is not fully commit bisecting. Thank you for your understanding.

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.) --- ApportVersion: 2.17-0ubuntu1 Architecture: amd64 AudioDevicesInUse: USER PID ACCESS COMMAND /dev/snd/controlC1: epirat 1708 F.... pulseaudio /dev/snd/controlC0: epirat 1708 F.... pulseaudio CurrentDesktop: Unity DistroRelease: Ubuntu 15.04 EcryptfsInUse: Yes InstallationDate: Installed on 2015-04-09 (6 days ago) InstallationMedia: Ubuntu 14.10 "Utopic Unicorn" - Release amd64 (20141022.1) MachineType: LENOVO 20CLS0JA00 Package: linux (not installed) ProcFB: 0 inteldrmfb ProcKernelCmdLine: BOOT_IMAGE=/boot/vmlinuz-3.19.0-12-generic root=UUID=28d14754-0ce2-45a9-a1aa-068caaab54d0 ro quiet splash vt.handoff=7 ProcVersionSignature: Ubuntu 3.19.0-12.12-generic 3.19.3 RelatedPackageVersions: linux-restricted-modules-3.19.0-12-generic N/A linux-backports-modules-3.19.0-12-generic N/A linux-firmware 1.143 Tags: vivid Uname: Linux 3.19.0-12-generic x86_64 UpgradeStatus: Upgraded to vivid on 2015-04-09 (6 days ago) UserGroups: adm cdrom dip lpadmin plugdev sambashare sudo _MarkForUpload: True dmi.bios.date: 01/23/2015 dmi.bios.vendor: LENOVO dmi.bios.version: N10ET28W (1.05 ) dmi.board.asset.tag: Not Available dmi.board.name: 20CLS0JA00 dmi.board.vendor: LENOVO dmi.board.version: SDK0E50510 WIN dmi.chassis.asset.tag: No Asset Information dmi.chassis.type: 10 dmi.chassis.vendor: LENOVO dmi.chassis.version: None dmi.modalias: dmi:bvnLENOVO:bvrN10ET28W(1.05):bd01/23/2015:svnLENOVO:pn20CLS0JA00:pvrThinkPadX250:rvnLENOVO:rn20CLS0JA00:rvrSDK0E50510WIN:cvnLENOVO:ct10:cvrNone: dmi.product.name: 20CLS0JA00 dmi.product.version: ThinkPad X250 dmi.sys.vendor: LENOVO To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1444766/+subscriptions -- Mailing list: https://launchpad.net/~kernel-packages Post to : kernel-packages@lists.launchpad.net Unsubscribe : https://launchpad.net/~kernel-packages More help : https://help.launchpad.net/ListHelp
