Hello All,

I've been searching the forums and product data sheets, release notes etc... but I can't seam to work out what is the current definative documetns I should be reading to

- A setup the WLC to ensure I have the correct requirements for the 7925g handsets

I have read documents on 7925gs needs and have 20% overlap of signal strength etc..  I have walked the site with 3 handsets on site survey mode and at any time the all have about -58 to -67 from multiple AP's.  Tried A freq and similar results of call audio loss.

I have read documents re various WLC's 5508 4400 2100 etc.. regarding QOS, WPA and roaming, but I still get an issue of rubbish roaming with about 3sec audio cutoff of voice between AP's and then call returns. 

A little about the site:

- 17 1142 AP's

- 2504 WLC running 7.4.100.0

- 13 7925g handsets

- 10 7600 series wired handsets (which work without fault)

- 1 x UC560

No radius server.  I even set the SSID to no security in an attempt to verify raoming, but appears this makes no difference.

Ive setup the 2100's and never had a problem.

Any pointers or documents I should be reading or a deffinative "set to this config" would be appreciated. 

David
