recently we deployed WDS network for one company.
Challenge was to cover large area, where distributor cars will be loaded and unloaded with cargo.
every distributor has Nokia 810 smartphone connected to central DB .............
everything worked perfectly excepting smart phones where unable to communicate with each other.
After checking and uncheking everything possible i found out problem source, problem source was a power saving mode in smartphone wireless configuration, turning off this mode helped and everything works es expected but now smartphone works only 4 hours on battery
earlier customer had a linksys ap and this mode worked on linksys ap.
MT team maybe you can solve this problem in future releases ?
