I have 100mb fibre connection,

running a point to point network using tp-link cpe510 5ghz outdoor access points, one in AP mode and one in client mode.

they advertise 300 Mbps wireless N, but as wifi is half duplex i would expect 150 Mbps.

I noticed the lan port on the AP is 10/100. so maybe with 5% loss i might be able to get 95Mbps,

Using the built in speedtest tool using one unit as server and one unit as client

I am maxing out, unidirectional at 61Mbps tx

and bidirectional 29.2Mbps tx and 40.3 Mbps rx = total 65.5Mbps,

so can i get better speeds or do i need to upgrade to more expensive gear? maybe from ubiquiti networks?

i consider myself techy but maybe I need to get a specialist out to look at it?

I want to achieve 95 Mbps downlink speed from the system that is implemented.

thoughts?

Definatly on a 40MHz channel?

I have had up to 90-95 on 150 meg 2.4GHz gear one way, so I would expect that to do more than that since it is 2x2 and 5GHz.

also forgot to say that the network is about 120m apart line of sight.

the highest option in the firmware is 20/40 mhz, that was already set on both units.

What does "the built-in speedtest tool" do, and how are you running a router as a client and server? Perhaps it's the measurement system that's the problem.

speed test tool, creates 10 parallel streams of packets and measures speed from server ap to client ap.

im not running a router as a client and a server, I have 2 outdoor CPE AP's to create a P2P network.

Random suggestions I have never configured one of these:

Is this current (1x AP / 1x Client ) your final intended configuration or a test configuration? I'm wondering if the other modes are faster.

The promo stuff indicates there is a proprietary protocol option for improved throughput. Is that enabled or disabled? Maybe try the other way.

I'm guessing they are already installed. Is it easy to get one of these units down and operate it physically closer to the other? Simple elimination of any interference etc.

Would I be correct in assuming both ends are plugged into a lan? I'm thinking eliminate that for a test in case there are weird Poe problems or something lan related holding it back.

1, yes current config is intended final config.

2, yes the propietary mode "tplink max stream" is enabled.

3, units are already installed, i borrowed a massive ladder to install them, dont really want to go up there unless i really need to.

4, the aps are plugged into the poe injector units, then routed back to LAN's. the internal speed test shows like 60Mbps, however speedtest.net spark server shows about 45Mbps down.

If this is your network I can assist with setting you up on the Geekzone UniFi controller so I can assist with diagnosing it? I just did an install not too long ago like yours and was able to max out a 100Mbit connection.

I am however operating on limited capacity at the moment using a WiFi hotspot on my phone because my internet is down...

Sounds to me like it isn't using both streams as those are speeds are what I would expect from a single stream.

Although, perhaps it's just a mix of half-duplex wifi and TCP letting you down. Maybe getting iPerf (or actually download jperf as its lots easier to use being graphical) and run a test with tcp and then with udp packets.

I do wonder though, why pick the TP-Link units over something like the UBNT NanoStation or NanoBeam?

ill download jperf and see what i find,

i brought tplink because it was what the retailer had in stock that was 5ghz, and ive used tp link stuff before, in saying that i know ubiquiti stuff is good too.
