Wireless Enterprise High-Density WiFi or Garbage?
My company had a vendor install "high-density" WiFi for our office which consists of (7) Ubiquiti E7s APs (by request), all pendant-mounted and configured approporately for our crowded RF environment.
We broadcast a primary SSID with both 5GHz and 6Ghz with the transmit power fine-tuned per AP. There are no issues with RSSI throughout the office, but everytime the office is at full capacity ~250 end-users - the performance completely takes a shit.
We get decent speed test results nearby the APs when the office is not occupied (400-800mbps), but when the office is occupied we have some spots that get 100mbps. The upload speed takes the biggest hit as we have seen over the past few weeks.
I have some users that are roaming to APs that are far away for no reason that I can find? I have also see that some users are roaming
I've been advised not to utilize minimum RSSI configs as this deliberately kicks endpoints off the AP and causes intermittent connection. Our end-users are running a lot of continous Claude Code instances and Zoom calls and we cannot have the connections drop. It should be smooth roaming. We have 802.11r - fast roaming enabled. We also disabled handoff suggestions for the same reason. We trialed handoff suggestions and those were the days we had the worst complains.
What do I need to do to fix this? Leadership is even considering switching to Meraki but I don't think that's the problem here. Do we need more APs? On average we have about 40 clients per AP for 7 APs. The space is quite large and mostly open area.
