Teams call no connection / sound after 11-15 minutes WC7500 controller
Hello Netgear community,
We have a strange problem with our Netgear WiFi system.
During a Teams call, after 11 minutes the connection is lost for about 10 seconds. After these 10 seconds, the connection is restored again. then again after 10 a 15 minutes a short outage for about 10 seconds.
The party on the other side of the line can still hear me during these 10 seconds sometimes, so the connection isn't than completely lost.
Our setup is:
Netgear controller WC7500 with firmware version: 6.5.5.24
Netgear WAC730 Accespoints.
two SSID's,
three VLANS.
One VLAN for one ssid and one for the other. And a management VLAN.
Radius WPA-2 enterprise.
2.4 ghz radio is disabled.
Wireless settings: --.> advanced Wireless (tab: 802.11a/na/ ac):
Turn radio on: True
Wireless Mode:802.11na/ac
Data Rate(na): Best
Data rate(ac): best
Channel Width: 20/40/80 mhz Dynamic
Guard Interval: 800 ns
RTS Threshold (0-2347): 500
Beacon Interval (100-1000): 100
Aggregation Length: 65535
AMPDU: enable
RIFS Transmission: Disable
DTIM Interval (1-255): 3
Preamble Type: Auto
High Density Bandwidth: High
Multicast/Broadcast Rate Limiting: disable
ARP Suppression: enable
Or as screenshot:
The clients are directly under the accespoint so it should not be a range issue.
The clients do not roam to another accespoint during the teams call.
2.4 ghz is disabled so they are always on the 5 GHz.band
We tested this issue with a accespoint from another brand in the same setup and we do not have encountered any problems during the teams call.
Can some one tell me what I should optimize in the Netgear setup to resolve this problem?
Thank you in advanced!!
