Massive Throughput Loss On WiFi
-
Hi All:
I am probably missing something obvious here but the enclosed diagram should explain my dilemma. I have excellent ( for Ireland ) incoming Broadband Service (280 Mbps). Serious loss always all over ( as per my diagram ) . . .
Any ideas, please?
Kind Regards
John

@JasonMinard Wireless only works as fast as the lowest negotiated speed. Pull it up on your phone (Assume Android) and check the negotiated speed. Open Wi-Fi and tap the connected SSID and see what the network speed is reporting.

Are you certain you're wifi is setup to use 5Ghz and not 2.4?

Oops - to be honest, I'm not sure - Would 2.4 Vs 5.0 Make that big a difference? Sorry, I haven't a massive amount of experience on WiFi and really appreciate your help . . . -

Wide channel widths will affect speed as well.

It looks like the wifi client is only connecting at 802.11g or 802.11a (54Mbit). Is that client capable of 802.11n/ac and wider channel width?

How did you get your baseline measurement? Hook a laptop up to the copper?
Did you use the same cable as the one that is plugged into the Ubiquiti AC Pro?
If you did not, then wire your laptop into the same cable that the Ubiquiti AC Pro is wired to and test the speeds. I'm not sure if you need to unhook the power injector or not.

That'll cause some issues for sure.

Definitely Same Cable . . . -

Definitely Same Cable . . .Can you see what speed your device is negotiating with the AP?

He could with his cell phone if he download WifiMan (from Ubiquiti)

If the client isn't connecting at N or AC, you won't get higher speeds. If the client hardware is capable, you can try modifying the adapter properties and forcing the preferred band.
Just an FYI - Whenever I see weird issues with Wifi affecting a single client, I usually find that the client is a Windows device that has been using sleep mode. Sleep causes speed issues and other weird issues like connecting not being able to connect to a VPN but no issues connecting to the internet.
