Hi,
I was trying to watch a video, old laptop connected to the sitting room TV, but VLC was having trouble, then NFS having trouble, not mounting the share, then sshfs also having trouble... (with a reboot in the middle, and an update yesterday). Then I notice that NM applet indicate an horrible signal level.
This is daft, the laptop sits 2 metres away from the house router with a perfect signal, yet it connects to the other WiFi on the house level above, terrible signal.
Why would it do that?
The machine is still on Leap 15.4, but has been running perfect for months. I just hibernated after each video session, no trouble, NFS working reliably. I just did run an update yesterday, and NFS was not automatically up after reboot. Did not occur to me to check the WiFi.
Why would NFS not switch over automatically to a much better signal?
-- Cheers
Carlos E. R. (from 15.5 x86_64 at Telcontar) Networkmanager does actually not connect to the strongest signal, but to the first signal. If you have memorized the wlan emitters in your NM the first thing it looks at is priority. Provided you have not given ANY priority, any of the WLANs you are registered to will connect. Once it is connected it will not automatically change to the a new stronger one. Such a highjacking would also not be desirable, imagine somebody who spoofs a SSID and does it with a higher signal strengths would highjack your NM to disconnect and re-connect to it to eavesdrop on it. If NM begins the frequency scan with 2.4 gHz and your best signal is 5 then tough luck.
If you did instead give priorities, it will first scan for the WLAN with the highest priority. If not available it will switch downward until it reaches the last available with the lowest priority in the list. For what I know NW is not able to choose by signal strength, prioritizing for it, if your priority settings are all set to zero. I actually do not consider this a bug. It is more of a choice or a feature to be enhanced.
