I'd been having trouble with big dropouts on a non-line-of-sight wireless link using a 917Mhz transciever board with a pair of RB411s.
I switched the protocol from nstreme to NV2 protocol and the problems just went away! Remarkable! Got close to no packet loss now.
802.11 was even worse than nstreme.
