 |
|
Here is what my system has.
| Code: | # lspci | grep -i wireless
02:00.0 Network controller: Intel Corporation Wireless 7265 (rev 59)
|
| Code: | # tree /sys/class/net/
/sys/class/net/
├── enp3s0 -> ../../devices/pci0000:00/0000:00:01.4/0000:03:00.0/net/enp3s0
├── enp4s0 -> ../../devices/pci0000:00/0000:00:01.5/0000:04:00.0/net/enp4s0
├── lo -> ../../devices/virtual/net/lo
├── sit0 -> ../../devices/virtual/net/sit0
└── wlp2s0 -> ../../devices/pci0000:00/0000:00:01.2/0000:02:00.0/net/wlp2s0
|
| Code: | # ip addr show dev wlp2s0
5: wlp2s0: <NO-CARRIER,BROADCAST,MULTICAST,UP> mtu 1500 qdisc noqueue state DOWN group default qlen 1000
link/ether 68:3e:26:c3:ec:fe brd ff:ff:ff:ff:ff:ff
|
I'm not seeing anything unusual, but when I try to connect to an access point, I get the following.
| Code: | # wpa_supplicant -i wlp2s0 -c /etc/wpa_supplicant/wpa_supplicant.conf
Successfully initialized wpa_supplicant
nl80211: kernel reports: Match already configured

I'd appreciate any suggestions on what to look for.

First, ensure that WPA and TKIP are disabled in the router (use WPA2 and AES instead).
If you don't have access to the router, wpa_supplicant has the tkip USE disabled by default. It has a weird quirk of seeing a mixed mode TKIP and balking when it is disabled. Try enabling the tkip USE when the router cannot be changed. |

That must have been the missing ingredient; I tried a different access point, and it worked as expected. Not sure why it didn't occurred to me. Thanks for taking time to provide a valuable suggestion.
