Symptom
Speed Test Fails frequently saying not able to find the speed test server.
Conditions
1800S running 8.8.261.0 with Speed test selected to run.
The number of SSID's selected with 5 AP's as default and 2 Bands. and 30 minutes interval. This configuration makes sensors to test assuming 3 SSID's.
3 * 5 * 2 = 30. 30 times within 30 minutes. Running speed test too many times causing server to throttle the requests and will not send server details..
Workaround
Update to latest sensor software.
Also this fix makes sensors to remember ndt servers so if query fails, it will try with worked one's.. so avoid the query server problem.
Also reduce the duration/Number of AP's and SSID's so sensor can run speed test less number of times.
