Slow WiFi

I'm using a ICX7150 along with two Ruckus 510 WAPs. One the WAP is configured as the Master. My ISP speed is 1Gbps and I do get over 900Mbps when I connect to my ISP WiFi directly and about 1Gbps when connected via ethernet.

However, when I'm connect to ICX7150 switch via ethernet or via Ruckus WAP, I don't get more than 450 Mbps. Please help to troubleshoot.

The firmware on the WAPs are up to date: Current firmware version: 200.15.6.212.27

Lights on the WAP:

Master: PWR, CTL, 5G and 2.4G are solid green

2nd WAP: PWR, 5G and 2.4G are solid green.

Hi @kramitkrsingh 

Thank you for the response and the information.

Please check the mentioned information.

 

Wireless Speed / Throughput (Theoretical PHY Rates)

5 GHz band (802.11ac Wave 2): up to ~867 Mbps — this is the maximum physical (PHY) data rate the AP can advertise under ideal conditions on the 5 GHz channel with 80 MHz channel width.

2.4 GHz band (802.11n): up to ~300 Mbps — maximum PHY rate on the 2.4 GHz band.

These numbers are maximum link rates between the AP and compatible client devices under ideal conditions, not guaranteed real-world speeds.

 

What This Means in Practice:

The 867 Mbps figure on 5 GHz is not the speed you’ll always see on internet speed tests; actual throughput to clients is usually lower due to:

RF interference and signal attenuation

Client device Wi-Fi support (not all devices support 867 Mbps rates)

Network overhead and shared airtime

Channel width and MU-MIMO efficiency
Users often observe real throughput around 300–500 Mbps per client under good conditions.

- On the 2.4 GHz band, speeds are significantly lower and typically best for range/coverage rather than high throughput.

 

To clarify, a 2.4 GHz connection generally provides longer range but at lower speeds, whereas 5 GHz frequencies offer faster speeds but cover shorter distances. The choice between 2.4 GHz and 5 GHz is often determined automatically by the end device (such as phones, PCs, Ring doorbells, Mac devices, iPhones). Additionally, network configuration (Wi-Fi/SSID/WLAN) may specify whether the network supports only 2.4 GHz, only 5 GHz, or both.

It's also worth noting that many electronic devices and appliances, such as microwaves, baby monitors, security cameras, garage door openers, and phones, operate on the 2.4 GHz frequency, which can contribute to interference. Screenshot below for the reference.

Thank you again for your patience.
