I wanted to reach out to others in the community to see if they were experiencing similar issues in a high-density dorm area. When looking at the controller > dashboard > access points we can see poor quality with the channel utilization above 90% on the 2.4 band.
We have some students using only 2.4ghz old laptops/devices that do seem to get a poor experience. Students using 5ghz are ok no complaints.
We have lower the tx power (max 9 and min 3) for 2.4 and enable mode aware arm on the g profile only. However, we still see the channel utilization high even with 0 clients. We did a survey with Ekahau and did notice some HP wireless printers that operate in channels 1, 6, or 11. However, we cannot tell the students to just buy printers that support dual bands lol anyways the dorm is a 7 story building with 455 access points. I understand there will be interference in the 2.4 because we only have 3 channels available to play with and spread them around.
Anyone experiencing high channel utilization with zero clients connected to an AP?
