@Tufkat Are both the 2.4G and 5G wireless connections having the same issue? How many of them? Try a different wireless channel, change channel width to 40MHz for the 5G and 20MHz for the 2.4G,...

@Kelko As replied earlier on #2, the C80 doesn't support bandwidth control, it only supports QoS.

@danielrosehill We will check it soon.

@TheGreyFox Got it. This will need to be analyzed by the support engineers, they will likely reach out to you via email, please check and confirm.

@Degsy Good idea, but no guarantee now. We will keep an eye on this kind of feedback. Thank you.
