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

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]
Which is in the end useless, because I see now that opensuse is far different from these settings, so they are not corresponding. But I think we are hit by a powersafe problem.
Thanks. I don't use network manager; I use wicked. I don't think I use power management either but maybe it does it anyway. Despite me activating the wireless in YaST, it seems to go away after a while. It now says: # ip addr show 3: wlan0: <NO-CARRIER,BROADCAST,MULTICAST,UP> mtu 1500 qdisc mq state DOWN group default qlen 1000 link/ether 80:a5:89:34:b8:27 brd ff:ff:ff:ff:ff:ff inet 192.168.179.32/24 brd 192.168.179.255 scope global wlan0 valid_lft forever preferred_lft forever and # iwconfig wlan0 wlan0 IEEE 802.11 ESSID:off/any Mode:Managed Frequency:5.18 GHz Access Point: Not-Associated Tx-Power=30 dBm Retry short limit:7 RTS thr=2347 B Fragment thr:off Encryption key:off Power Management:off whatever all that means! -- To unsubscribe, e-mail: opensuse+unsubscribe@opensuse.org To contact the owner, e-mail: opensuse+owner@opensuse.org
