Different Tx/Rx rates of connected devices to my WiFi Router

Posted on

Problem :

The wireless devices connected to my Wifi router have different Tx/Rx rate. For example, the Tx rates of two devices are 780 and 54 Mbps. I am curious about what causes these differences. Are these differences caused by the quality of hardware in these devices or some other factors? The wireless device with Tx rate of 780 Mbps, which is a iPhone 11 pro, gives me the idea that because it is new and expensive, it has greater Tx rate! Moreover, another device (Oneplus 7T phone) which is in the same distance from the router as iPhone 11 pro, has a Tx rate of 260 Mbps!

The List of Connected Devices To My WiFi Router

Solution :

Devices will sometimes select a lower transmission rate based on the quality of the connection (or to save power), but ultimately the quality of the connection has many factors, the 3 most important are:

  • the wireless standard used
  • the frequency used
  • the distance between the router and the device

If you can’t move the devices closer to the access point (router), you can ensure that your router is configured to use the newest wireless standard that your device supports. An example of this would be to switch your router from b/g/n mode to just n mode.

From your screenshot, some of your devices connected using a frequency of 2.4 Ghz, instead of your router’s faster frequency: 5 Ghz. Try to connect that device your router on the 5 Ghz network Note: Some devices only have 2.4 Ghz available, and are unable to connect on 5 Ghz.

Tip: Sometimes you may have to give your 2.4 Ghz network and your 5 Ghz network different names (SSID’s) in your router’s configuration in order for you to connect your devices to the faster network.

Refer to this table for the maximum speeds you can expect based on the wireless standard and frequency.

| Standard | Frequency | Theoretical Speed   |
|----------|-----------|---------------------|
| 802.11b  | 2.4Ghz    | 11 Mbps             |
| 802.11g  | 2.4Ghz    | 54 Mbps             |
| 802.11n  | 2.4Ghz    | 300 Mpbs            |
| 802.11n  | 5Ghz      | 900 Mbps            |
| 802.11a  | 5Ghz      | 6-54 Mbps           |
| 802.11ac | 5Ghz      | 433 Mbps - 1.7 Gbps |

That being said, your Tx and Rx rate will be capped at whatever rate you purchase from your ISP, for example, you could have a Tx of 300 to your router but if you only have 100 from your ISP, 100 will be the maximum speed achieved to online servers.
