Why do I have so many issues with Cisco AP installs?

Constantly getting pulled in to fix either customer or wired network contractor Cisco installs. Usually changing controller settings to stop auto channel, limiting power adjust settings and limit the control the automated routines can do. But I have a number of customer sites where I just can’t get the clients to not randomly drop even though we have -65dbm RSSi and power at max of 16dbm of combined AP & antenna gain on 5GHz. Roaming isn’t occurring correctly or quickly even though we have client roam threshold set at -70. But I can’t stop the “sticky AP” syndrome.

Sorry I can’t be of any help, but to add seeing very similar symptoms on our installation mainly 3700’s Series APs and 9800 WLC (but migrated from 5508s which were experiencing the same issues). I’m interested if you find a resolution and I will post if I find anything concrete.

I do see the same issues. Also with Cisco you need to design for RRM if they are going to use it. APs too close to each other (RRM turns the power down so low) and clients with too many choices of AP to connect to. Remember the client makes the decision when to roam not the AP. Does the client have any roaming parameters . I have found turning of band steering to be beneficial if used and running separate SSID for each frequency.

Yeah, RRM mode, term stolen from Psion but means something really different, isn’t beneficial in a warehouse. You are viewed as a demon trying to get a customer to turn it off. When they called it Auto RF I had to get the customer to shut it all off and statically set the AP power & channels. They then complained that they paid $15K for a central console for the AP’s. Sorry, you didn’t ask. I have got the customers to limit the adjustment range in RRM so that we keep the DBM level within acceptable limits of both high & Low. Still get issues. Monitoring Mode causes many clients to go crazy when the AP drops them without any apparent reason to the point of having to reboot it. We have statically set channels on 2.4 but the 5.8 still drops even though we have not repeated any channels??? Next step is a WIFI monitoring software to see an entire net trace of the transactions.
