Your Wi-Fi network competes for airtime with all other Wi-Fi devices in the home. Current Wi-Fi technology only allows for the modem to communicate with one device at a time. A Wi-Fi device that uses older technology, such as the 802.11b or 802.11g standards, may contribute more to airtime congestion because these older Wi Fi standards transfer data at a slower rate. As a result it slows the other devices on the network down to its level.
How to reduce airtime congestion
- Try disabling older Wi-Fi devices on your network to see if performance increases. To help identify which devices are using older Wi-Fi standards, you can look them up on a website such as the Wi-Fi Alliance.
- As a rule, you may want to upgrade devices that are 5 years old or older.
