One option would be to install the file as a standalone on your iOS device, then sync it back to your server version when you are relialy connected. Have you looked into that option at all?
We've found FileMaker Go to be extremely resilient in WiFi environments.
But, most folks are careful, in setting up the networks, to make sure the various work areas are saturated with signal/noise ratios in the 50's or higher.
iStumbler is a great tool in the Mac environment (there are PC equivalents) that will provide metrics on the wireless network.
i tried that but once the file has these issues it wont open
thanks - I will have another go at the people who installed - they are blaming our system (and of course filemaker - they are jealoous) - they found errors in one part of the building so hopefully they sort for the rest of the building
In my response above I should have said 'not careful' vs. 'careful'.
The great part about the iStumbler tool is the version 99 download is free (substract signal from noise) or the paid version is only $20.00 (separate s/n column).
It will also show full dropoffs as well as signal, noise, nearby (conflicting) wifi hotspots.
Also check to make sure that the wifi connection is to the higher speed 3 digit channels (149) vs. the slower connections (11). You can use a GoToMeeting (or other) connection to actually check it yourself. It is what we do. If there are professional IT folks around, there is no reason why that they can't make a wifi signal map of all the areas users will access the database. They can use a tool for that or just manually use a laptop.
Commerical buildings use metal framing (usually) and that affects the signals. Flourescents, noisy generators, A/C etc. call all cause issues in additional to hotspot interference.
At home, with wooden framing, we have less of these issues. Even so, in my home I need three Airport Extremes to saturate the entire area and keep all those Netflix streams going strong from various family members <grin>.
Easy stuff to get out of the way.
