slow links

The speeds of my links are really horrid, lucky to get 2MB
the multipoints are set as AP Bridge
5GHz A/N
20/40 HT Above

The link is directly line of sight and only about 150m
signal is around -21/-40
signal to Noise is 76dB
Noise Floor -114dbm

any suggestions

what equipment are you using? what antennas?
a noise floor that low is unbelievable imo.

made some changes implemented nstreme and nv2 still lucky to get above 20Mbs
using sector antennas (not sure of exact model as inherited this project) and a router board RB435G as central point, sextants SXT 5HnD connecting to this

unbelievable in what way?

the only thing that is a potential issue is we are cutting across power lines

Signal is too high, set power to give -50+ , SNR is very high and probally caused by RF overloading, what is your CCQ?

do not appear to have the ability to turn the power down on the Sextant or am missing something?
