Seems like 24dbi grids a bit overkill for a 8 mile link. We use linksys wet11's placed in a outdoor enclosure and set it up for poe use with 15dbi grid antennaes and get some healthy speeds.
As far as the the repeater is concerned you do lose quite a bit. have you tried this: your home --radio with yagi /patch antenna -----neighbors house ith yagi or patch antenna hooked up to a small switch then take the out put of that and hook that up to a wet11 with a yagi or grid antennae---------8 mile link---to your other wet11. Considering what hardware you have turn off the repeater mode If you are only 300 feet from your neighbor do a pt to pt link. Then do a bridge for the other two sites. I am not promoting anything but Jack Unger started one of the first wirless isp's here in the bay area. He is quite knowledeable and helps individuals with problems like yours. He has just written a very good book http://www.ask-wi.com/book.html His phone number is on his web site. Hope this helps.

Here is my setup. Home: DSL Modem | Dlink DI-604 firewall/NAT | | Dlink DWL-900AP+ (AP mode) | [14dBi Yagi] ~ Neighbour's roof: ~{300ft}~~~~~~[24dBi Parabolic dish]-Dlink DWL-900AP+ (repeater mode) ~ ~ Remote location: ~~~~~~~~~~{8 miles}~~~~[24dBi Parabolic dish]- Dlink DWL 900AP+ (bridge mode) | PC I was forced to use a repeater, as there is no line of site from the Home with the DSL to the remote location. The repeater is set up on a neighbour's roof, with the parabolic dish pointed at the remote location 7.9 miles away (there is a line of site from the neighbour's roof to the remote location on the top of a mountain). The 14dBi Yagi at the house picks up the back scattered signal from the parabolic dish on the neighbour's roof without difficulty. At the remote location, my Orinoco gold card, when connected to the parabolic dish, records signal of -75dB, and is able to connect in client mode (using 128bit WEP). At the remote location, I am unable to get the DWL-900AP+ to connect in client mode. But it does connect when it is set to bridge mode. The problem is that the wireless connections at the remote site seem to cycle down every few seconds, whether I am connected with the Orinoco Gold PC card or the DWL-900AP+ in bridge mode. Pinging the AP from the remote location shows 20-30% packet loss. The net throughput of the link is on the order of 50kbps, but the link is largely useless because of repeated dropping of connections. Previous discussions on this list have alluded to possible overheating of the repeating AP -- but this behavior is the same on cool evenings (~40 degrees F) as during the heat of the day (70-80+ degrees F). Anyone have suggestions for how to debug/fix this problem?
