I'm a complete noob when it comes to wireless!
I just turned wireless on on my openSUSE PC (Leap 15.0) in order to be able to control a TP-Link HS110 smart plug. But the wireless seems to be flaky on the PC and I have no idea why.
I set it up in YaST - I use Wicked - and it seemed to work, then it stopped, then it worked, then it didn't etc. YaST now says:
RTL8821AE 802.11ac PCIe Wireless Network Adapter (Not connected) MAC : 80:a5:89:34:b8:27 BusID : 0000:03:00.0
Device Name: wlan0 Started automatically at boot IP address assigned using DHCP
but on my router's network management page I can see an IP address for my PC's WLAN interface (it's on a different net to the wired LAN) and part of the time it indicates a connection and part not. When it does the signal strength is -73 dBm.
I'm no expert either, but maybe that is too low? I have three access points -
# iwlist wlan0 scan | grep Signal
Quality=70/70 Signal level=-38 dBm Quality=41/70 Signal level=-69 dBm Quality=58/70 Signal level=-52 dBm
2019-11-09T17:33:55.580226+00:00 acer-suse kernel: [9051585.842867] wlan0: deauthenticated from 9a:9b:cb:9d:ab:52 (Reason: 34=DISASSOC_LOW_ACK)
I think the above is the real problem - I would try moving the laptop to another location, trial&error, see if it improves. It does seem weird that other devices have no problem connecting though.
Thanks Per. I don't own any laptops; never have. If you mean my PC it's a desktop, so quite a bit more awkward to move. Even turning it around to see if I can see if there's a place to attach an external antenna has been too much effort so far :( But maybe I need to do that now.
The other devices do seem to swap between connections on 5 GHz and 2.4 GHz depending where they are in the house, so I guess signal levels may be marginal. I have the same problems with a ASUSTek Computer, Inc. N10 Nano 802.11n Network Adapter [Realtek RTL8192CU] The problem seems to arise with some RTL chipsets by the powermanagement of networkmanager. Suggested solution (that I am going to try now) are:
1) change the value of wifi.powersave located in /etc/NetworkManager/conf.d/ default-wifi-powersave-on.conf from 3 (enabled) to 2 (disabled). This effectively makes the effects of sudo iwconfig <interface> power off permanent. 2) add an explicit directive (wireless-power) to control power management in the /etc/network/interfaces configuration file (e.g. Disable it for wlan0 with DHCP): auto wlan0 iface wlan0 inet dhcp wireless-power off Not sure if this is going to solve your issue but you may have a try.
