Unifi AC Pro slow speeds

Hey Everyone. I just got switched over to Verizon's Gigabit service the other day, and I've been having some issues with my wifi. Hard-wired, everything is perfect, getting ~950 up and down. On wifi however I'm only averaging about ~70 down, wifi uploads around 2-300.

 

My setup is as follows: Fios Quantum Gateway (just used as a router, wifi is off) > TP Link 8 port PoE switch > 35 ft Cat6 cable to Unifi AC Pro. Even sitting directly under the AP, wifi speeds don't get over 100 Mbps

Any idea what could be causing this? I know I'm not going to be getting gigabit speeds over wifi, but I was expecting something a little better than I was getting with my old 150/150 plan...

Re: Unifi AC Pro slow speeds

What is your RF environment like?
Are you using a 80MHz channel width on the 5G?
Is your client connected to the 5G and does it support 80MHz channels?
Does the AP have a 1 Gb connection on the wired interface?

- Channel width on 5G is set to VHT40

 

- I'm using a 2017 Dell Latutude and a note 8 to test, so I beleve they both support 80 mhz

 

- Uplink to the AP is showing 1000 Full Duplex

Re: Unifi AC Pro slow speeds

Set your 5G to 80MHz, and make sure your clients are connecting to it.

Generally you want the 2G power ~medium and the 5G at high.

What channels are you using for both bands? Your 2G looks fairly polluted with people running 40MHz channel widths in it, you *may* be able to improve your 2G connection with the cell size option.

Have you done any kind of site survey?

Free software to accomplish this;

Mac: use the built in Wireless Diagnostic or NetSpot Free https://www.netspotapp.com/

PC: Acrylic WiFi Home https://www.acrylicwifi.com/en/wlan-software/wlan-scanner-acrylic-wifi-free/ or the aforementioned NetSpot Free

Android: WiFiAnalyzer (open source) https://play.google.com/store/apps/details?id=com.vrem.wifianalyzer&hl=en

iOS: Unfortunately Apple hides the wifi chip behind the API and does not let apps have much in the way of data from the chip. In iOS 11 Apple won't even let apps have access to the MAC Addresses in the ARP tabel. You can use the Airport Scanner tool to find Wifi networks but you will not get the same detailed information as the other devices.
