This article will cover the causes of this issue and provide a detailed solution to help you get back to your normal Wi-Fi speeds.
Causes of Slow Wi-Fi Speeds
There are a few possible causes for slow Wi-Fi speeds on Ubuntu 24.04 LTS when connected to Deco M5 mesh access points. These include:
- Outdated drivers for the wireless card
- Incorrect Wi-Fi configuration settings
- Interference from other devices
- Hardware limitations
Checking for Outdated Drivers
The first step in troubleshooting slow Wi-Fi speeds is to check if the wireless card drivers are up-to-date. To do this, follow these steps:
- Open a terminal window
- Type
lspci -nnk | grep -iA2 netand press Enter - Look for the wireless card in the output. Note down the device ID (e.g. 14e4:4365)
- Go to the manufacturer's website and search for the latest drivers for your wireless card
- Download and install the drivers
- Restart your laptop and check if the Wi-Fi speeds have improved
Checking Wi-Fi Configuration Settings
If the drivers are up-to-date, the next step is to check the Wi-Fi configuration settings. To do this, follow these steps:
- Open a terminal window
- Type
nm-connection-editorand press Enter - Select the Wi-Fi connection and click on the Edit button
- Go to the IPv4 settings tab and make sure the Method is set to Automatic (DHCP)
- Go to the IPv6 settings tab and make sure the Method is set to Ignore
- Click on the Save button to save the changes
- Restart your laptop and check if the Wi-Fi speeds have improved
Checking for Interference
If the Wi-Fi configuration settings are correct, the next step is to check for interference from other devices. To do this, follow these steps:
- Open a terminal window
- Type
sudo iwlist scanand press Enter - Look for other Wi-Fi networks in the output. Note down the SSIDs and their channels
- Go to the Deco M5 app and change the Wi-Fi channel to a channel that is not being used by other Wi-Fi networks
- Restart your laptop and check if the Wi-Fi speeds have improved
Checking for Hardware Limitations
If none of the above steps have improved the Wi-Fi speeds, it's possible that the wireless card has hardware limitations that are preventing it from achieving normal speeds. In this case, you may need to upgrade the wireless card to a newer model that supports faster speeds.
