From: Vitalie Vrabie on 14 Mar 2010 13:46 my NDIS IM adds some network functionality which is possible only in ad-hoc mode of the wifi network and only if the modulation is OFDM and not DSSS. (802.11b is DSSS and 802.11g is OFDM) i reserved a particular SSID as an indication to my driver to activate itself. i want to make it disconnect the media if it doesn't qualify, then force 802.11g mode, then retry the media connection. also i don't want to force anything that is not related to that specific SSID. q1. how to check (from a usermode application) if the adapter is at all capable of ad-hoc on g? (the application that installs the driver could check for this condition and explain the situation to the user.) q2. how to force it to use g and not fall back to b? (i saw vendor-specific utilities that do this thing for particular adapters, but i'm interested in a generic possibility for all of them. this must be done in the driver in my case.) q3. how to correctly fail the media connect (from my NDIS IM) if the underlying layer has connected with line conditions that don't qualify? (fail and disconnect, then force g mode, then reconnect) |
