I just installed IAP VC with around 4 units of IAP 207 and IAP 305 to our customer. The IAP 305 will be the preferred master VC. Current OS is 220.127.116.11-8.3.0. Their environment is mixed between gn and ac client.
Now our customer reported me; they saw clients that're gn type were a poor performance (see picture). These gn clients are often time out when connecting to host (checking by using a ping command). Also found that bandwidth swings (not consistency). Singnal strength is no issue. Any suggestion, please.
Note: the configuration I used:
1. All of ClientAware, ClientScanning, ClientMatch, are enabled.
2. And min-tx-power 18, max-tx-power 24, band-steering-mode prefer-5ghz, air-time-fairness-mode default-access
Try making the min-tx-power 12 and the max-tx-power 18. Your power might be too high.
Can you send us the screenshot with the list of access points?
Thank for your suggestion. I'll consult customer tomorrow. Here is a snapshot of existing devices.
After adjusted, customer still found the problem - sometimes client gets timeout and low speed inspite of not far from access point.
I also attached our configuration. In addition customer infromed that the WLAN adapter client was automatic adjusted speed. Sometimes it can change to ac. Then an, finallly gn. When it's gn, connection will lose or inconsistency.
Under RF> ARM, uncheck 80 mhz. 80 mhz channels should not be used with client density.
Thanks. Will feedback you tomorrow.
After disabled 80 mhz. Problem on clients still occured (see picture). We found that during client notebook adapted to a new speed, timeout would occur.
Please PM me the tech support.
Just sent to you a few seconds.
With a good supporting from Aruba TAC and CJoseph, now the issue was found. The issue came from the 2nd DHCP server that was generated another subnet in the IAP main subnet.
