Are there any other customers on the second
hop?
Does the same thing happen to them?

This is an 802.11b hop link. It goes 9.4 miles
from a DLB1300 AP with 120* 14dBi sector to a 24dBi Grid on an CM9 in a RB230.
From there it is 2.0 miles to the customer. The AP has a 90* 9dBi (I think) on
a CM9. Customer is a 15dBi grid to an SB Outdoor radio.
Does the 9.4
mile link constitute a "long link?" It appears the double ping replies are
only if I ping from the first AP through the other to the client. Pinging from
the clients near AP doesn't get the double replies.
