Gedetailleerde hoofdoorzaak:
802.11-verbinding is mislukt door statuscode 18: de koppeling is geweigerd omdat het aanvragende station niet alle gegevenssnelheden in de parameter BSSBasicRateSet ondersteunt
(Deepl.com translation:)
Detailed root cause:
802.11 connection failed due to status code 18: The link has been rejected because the requesting station does not support all the data rates in the BSSBasicRateSet parameter
What it says .... your Windows PC (requesting station) does not support the Basic rates announced by the AP. In other words: the AP announces basic rates "basic-rates-a/g=6Mbps,12Mbps,24Mbps" , but the Windows PC does not support all of them. The PC may support 6 Mbps but maybe not 12 or not 24., or just another combination.
If you play with "basic rate/supported rate" make sure you understand what they mean and when they are used, or just don't fiddle with them. Using basic rates 6,12,24 is a bit odd in this. (I would understand 6 or 6,9,12 or 9,12,18 or 12,18,24 or 18,24 or 24 for basic rates. Mostly the lowest value is used. 6Mps is always used for the first request from the client even if disabled on the AP.) Supported rates must always include all basic rates and normally have more (higher) rates. These supported rate settings must support all basic rates indicated on both devices.
So the error says: the supported rates on the Windows PC do not include 6,12 and 24 Mbps, which are announced by the AP.
