i have a question Cisco AP 1815M ping to internet with high time MS.
i tried to connect AP with different network but output same high time to ping internet
Cisco AP 1815M connect with virtual WLC So i search in document and not found VWLC support on datasheet cisco 1815M but i can join VWLC and 1815M but still issued ping high time.
When you say high ping is that from the AP CLI or from client connected to AP?
What is the ping response to the default gateway?
What is the ping response from the switch to the internet?
The vWLC only supports local switching for the WLAN so if the latency is from network to destination then need to investigate there.
From wireless side, have you confirmed the client is connecting with good signal level, SNR etc?
What version vWLC are you running? The 1815m requires 8.5.x or above which the vWLC will support it.
