** Description changed:
With Xubuntu 17.10 the following problem occurs on a Lenovo X230 Laptop:
- Boot from live-ISO
- Click on network icon in title bar and edit LAN-connection
- Change MTU from Auto to 1492
- Connect LAN cable
=> LAN network keeps connecting and disconnecting in an infinite loop
(No wireless network is configured.)
The error did not occur on Xubuntu 16.04. The same situation occurs with
Xubuntu installed on the SSD. I took the ISO for this bug report, in
order to exclude wrong settings on the installed system.
- This is my first bug report - I hope I did not do too much wrong. If
- necessary, I can provide more information.
+ WORKAROUND: Don't adjust the MTU.
