Hi all,

I've got several links setup with the new Litebeam 120 sector APs and the
Litebeam AC CPEs. One of the links I have shows extremely poor transmit
numbers when I run a speed test, but it always shows slow transmit problems
depending on which end of the link I'm on.  Here's the link

Tower w/Litebeam AP 120  --> Litebeam CPE on shed  <-- Shed -->  Litebeam
120 mounted back-to-back with CPE -->  Another Litebeam CPE on a client's
house.

The Tower->Shed link is about 2.5 miles LOS and sits at about -56 on both
Chain 0/1, the Shed->House link is less than 1/4 mile and it's also LOS
with about a -42 signal on both chains.  All devices are running
8.0-beta19, which has been otherwise pretty solid as far as I can tell.

If I login to the AP at the tower, I get approximately 6Mbps RX, 0.75Mbps
to the house CPE.  If I login to the house CPE, I get the same thing (6Mbps
RX, 0.75Mbps TX) to the AP.  If I login to the edgerouter in the shed which
bridges the two wireless connections, I get much better results, roughly
25-35Mbps each way.

Has anyone else seen this?  I worried the short link was too hot at -42, so
I've temporarily turned on the auto power control to see if it helps.  So
far it has reduced the power, but hasn't seemed to help the end-to-end
speeds.
