Fair point, but a bit afraid to run zypper dup because not knowing what all will break. If no other insight, will do so.

I am running tumbleweed on a Dell XPS 1575 currently kernel 4.17.3-1.

Normally when I start the machine I can connect wireless to my phone via tether from Yast using wicked. I now find in a shared work office space that I am unable to connect to my phone via tether, as before. Journal reports

wicked[6795]: wlp2s0 setup-in-progress

If I bring down the interface

# wicked ifdown wlp2s0

Then journal reports

wicked[6795]: wlp2s0 device-ready

If I turn on WICKED_DEBUG = 'all' in /etc/sysconfig/network/config then when I bring the interface up and down in wicked with

# wicked ifdown wlp2s0 # wicked ifup wlp2s0

then journal reports repeatedly 'Scanning signal received (not handled)'. Usually repeats message 5-10 times.

I have also observed that iwlist fails to work in shared office space where there are a huge number of SSIDs advertised.

# iwlist wlp2s0 scan wlp2s0 Failed to read scan data: Argument list too long

# iwlist wlp2s0 scan essid WeWork wlp2s0 Failed to read scan data: Argument list too long

Using the is command works fine.

# iw wlp2s0 scan [lengthy output]

If I leave the shared office e environment and return to the street, both iwlist and yast/wickedd begin to work again.

Question: Is it the case that yast/wickedd have a dependency on iwlist (that can cause wickedd to fail when iwlist fails on too many SSID results)?

If so, can yast/wickedd be configured to use iw instead of iwlist?

That's an ancient TW version. When did you last zypper dup? And, no btrfs? Running TW means you 'have' to zypper dup regularly. Otherwise choose Leap 15 as your distro. FWIW: My TW has not broken in years. Every release snapshot (TW, not btrfs) goes through openQA to test it.
