We are trying to delivery a 500M L2 service to a client but are having difficulty in providing 500/500M Duplex. The service is tested according to RFCC2544 where the packet loss requirement is 0.1% (they will accept up to 0.9%).
When the client runs their test they only manage 320/320M with 0.9% loss. We need to get a minimum of 400M/400M, ideally 500/500M
Are there any tips, tricks or things i can change to get more out of my links?
Ive tried everything i can think of
Shifting around frequencies
Playing with power settings a lot until i have found the sweet spots
Enhanced Mimo (didn’t really do anything[Codebox=html5 file=Untitled[/Codebox])
Short CP (Gave a big boost in speed and is currently enabled on all links)
See attached the topology, link count and radio GUIs.

Why are you shifting frequencies? Are they all connected via wireless?
Why are you shifting frequencies?To see if it would resolve the problem but it didn’t.
Are they all connected via wireless? Yes they are all connected via wireless
