9800 APs, Catalyst Centre Intel Reported Errors - Invalid IE (49)

Aaron Harrison — Thu, 20 Nov 2025 18:05:51 GMT

Since upgrading to 9800 (IOS : 17.12.5) series controllers, my Intel clients of al types, on various types of AP are frequently reporting 'errors' like so :

Frame Type: Beacon

Error: Invalid IE (49)

Has anyone see similar and managed to investigate?

Thanks

Aaron

- @Aaron Harrison To exclude driver issues : use the latest intel wi-fi driver(s) on a specific device and check if that makes a
difference

same behavior, onboarding incomplete and the error is invalid IE (49) but the client is able to authenticate, so not sure if this is a cosmetic issue or real problem

- @jucape2009 If the client has no further wireless issues , I would say it's cosmetic
