Asking a AP-mode WiFi interface to scan will disconnect any associated clients because during the scan, the AP can't beacon. The AP will also lose any traffic the client sends to the AP while it's on other channels. A scan can sometimes be forced, but the only two mac80211 drivers in the 4.9 and earlier kernels that advertise this are the TI WiLink ones (in some embedded devices the Nokia N900/N9/N950 phones) and ath10k ones. Of non-mac80211 drivers some "support" it (ath6kl, brcmfmac, mwifiex) while others don't (wil6210, rndis). But you'll still drop traffic for any connected clients. NM could theoretically request/allow scans if it could figure out how many connected clients there were while in AP mode. That would be a nice enhancement. If you want to switch the device from AP to Client mode, you would create two WiFi profiles (what NM calls "connections"). One for client mode, one for AP mode. You can then switch between them: nmcli con up "My AP" --wait 20 nmcli con up "My Client" --wait 20 nmcli dev wifi list (the switch to client will have already scanned) Or, if all you care about is scanning, you can just disconnect: nmcli con up "My AP" --wait 20 nmcli dev disconnect wlan0 nmcli dev wifi rescan nmcli dev wifi list nmcli con up "My AP" --wait 20 Dan > Thanks > > STÉPHANE BOUCHER > Consultant software > > D-BOX Technologies Inc. | A. 2172 de la Province, Longueuil, QC J4G > 1R7 CANADA | T. 450-442-3003 | W. d-box.com<http://www.d-box.com> > > > AVIS : Ce courriel contient des renseignements confidentiels.
