the ralink driver misses one very important feature to reliably run a larger 
adhoc mode cell: Assigning a manually chosen BSSID. Therefore, it would not 
suprise me if you experienced "cell splits" from time to time.
To verify this theory you can watch the BSSID (Cell) field on the involved 
nodes and run a continuous ping on your statically configured setup. If I am 
correct you also will experience packet loss and the BSSID will change.

Regards,
Marek
