WAP581 normal ping times to lan and internet ips but super high ping times to wan ip to home office

[Calexander02]

Replacing a WAP551 with the new WAP581, installation seemed straight forward then ran into a snag. The 551 running ping tests normal latency to wan ip addresses 

after installing the 581 running the exact same settings as the 551,and tried dhcp, if i ping www.google.com ill get 60ms ping times and download speeds will pull 60+ upload 10+, but when i tried network resources times out, times out to our exchange server, and ping times hit 900+ ms. Tried turning off various items, factory reset, ect...i am at a loss on this one. The 551 works perfect yet the 581 50/50.

Hi Calexander002,

As far as I know, AP acts as a 'hub'. If you try to ping to one of your WAN IP, it might be affected by your WAN link utilization, quality, etc. Try to ping the gateway or local LAN station, not your WAN nor your other station connected via wireless. In my experience, this works better in comparing AP performance.

Cheers.

This is something that we have done, I even had cisco support looking at it. Strange thing is pinging the gateway results in varying ping times from 100-900 ms but pinging an outside ip such as google results in consistent ping times of 50 ms or less. Cisco says the WAP shows nothing in the settings that explains this.

Hi Calexander,

Well, that's kind of strange since you have to pass the same path when the packet goes outside.

Have you tried comparing the traceroute? At which point you get a higher latency? And does the packets goes through the same path. Just wondering.
