D-Link support says
WPA uses TKIP.
WPA2 uses AES
iw wlan0 scan says
WPA: * Version: 1
* Group cipher: TKIP
* Pairwise ciphers: TKIP CCMP
* Authentication suites: PSK
one thing that is interesting is I noticed my neighbors wifi says
WPA: * Version: 1
* Group cipher: TKIP
* Pairwise ciphers: CCMP TKIP
* Authentication suites: PSK
The pairwise cipher is revered. I’m not sure if that makes a difference at all but I just noticed it.
I also tried to change my wifi secuirty mode to
WPA2/WPA3-Personal
WPA3-Personal
and NetworkManager says that Authentication type of wifi network not supported and the iw wlan0 scan does not have a WPA section. My guess is it’s … not supported.
Is TKIP supported? Is it possible that my router is is asking to use TKIP first and it’s not supported and not falling back to CCMP?
I’m far from a networking specialist so I’m grasping at straws here.
I was able to successfully connect to the wifi with wpa_supplicant so it really does seem NetworkManager does not play nice with my router. I may try going back to DD-WRT, which is what I had used since I bought the router, but I had issues with momentarily dropping connectivity. Not a huge issue normally but since my wife and I are both working from home these days, I can’t have an unstable internet connection while hosting a meeting.
Anyway, if anyone has any more suggestions please let me know, I appreciate the help.
