Did this issue start happening after an update/upgrade? Was there a prior kernel version where you were not having this particular problem?

Would it be possible for you to test the latest upstream kernel? Refer to https://wiki.ubuntu.com/KernelMainlineBuilds . Please test the latest v4.7 kernel[0].

If this bug is fixed in the mainline kernel, please add the following tag 'kernel-fixed-upstream'.

If the mainline kernel does not fix this bug, please add the tag: 'kernel-bug-exists-upstream'.

Once testing of the upstream kernel is complete, please mark this bug as "Confirmed".

Thanks in advance.

Christophe, the bios is updated to latest available version. On Lenovo x220 support website the version 1.42 is not available, for download is returned a file of version 1.40 (8duj25us) http://support.lenovo.com/pl/pl/products/laptops-and-netbooks/thinkpad-x-series-laptops/thinkpad-x220/downloads/DS018805

[Marcin (marcincelebucki)]

Joseph, the kernel is default from xubuntu 16.04 release. The issue not occurred after update/upgrade, because of the peculiarities of installation method ( persistent mode ).

The issue occurs when a network is changed, wwp0s29u1u4 is a interface of mobile network who is required introduction captcha every hour for unlock internet access.
