We have a zone director managing 4 access points, model zf7363 and software version 22.214.171.124.110. All used to work fine, we could roam between them all and response fine. All traffic goes out via a firewall and ADSL lines which test fine (as we can connect direct to confirm line is fine).
3 of the access points all work fine, with very low pings.
However on just one of the access points, when I'm connected to that access point (verified via the zonedirector login), I get ping responses of 2-3 seconds. If I roam to near one of the other access points, it switches and ping goes down.
This is if I'm right next to it. I've also waited until everyone else is out, and no one else is connected to the AP other than myself. I've tried a power reset. Only thing I notice is the 5k light on the box flashes.
I (and everyone else), get dropouts to that AP and response of 2-3 seconds. Sometimes however it is absolutely fine.
Hiya, many thanks both for the replies. I'll see if I can swap one of the other APs around (fiddly as they are attached to wall, so may be a wee while before I can do that, as don't have permission yet)
Looking at the PHY errors, on the suspect one, there are quite a few errors...
I'm not familiar with these, but obvious the 802.11g stats look suspicious (uptime 19h).
Can someone confirm if those stats are on a pretty much unacceptable level, and if so any likely suspects ? Its connected to a wall, and I've tried switching everything off in the immediate vicinity with no one around (possible its something next door through the wall?). Is there any way to somehow test interference, or is it a specialist equipment thing ?
Is there a way to disable 802.11g if necessary (or not possible/unadvisable) so people would only connect to 802.11a ?
Disabling 802.11g on THAT AP is easy however if your client/device population comprises of 2.4ghz band based then doing this may end up creating a coverage hole. Here is how we do it --> http://prntscr.com/3fewiw
If i would be in your place then would follow the below steps:
1. Find out the real culprit and remove it (if possible) Or if change its frequency/channel.
2. Use interference avoiding mechanism like Channelfly.
