Is it possible to solve the voice delay in the WEB conference and the "this function" of the Wi-Fi router by turning it off?

A "WEB conference app" that is inseparable from telework. There are various types, but it is generally decided by the convenience of the place of employment or business partner. So when a problem arises, it may be quick to give up saying that you can't survive with your own ingenuity, such as reviewing the settings of your computer. Voice delay of WEB conference application, may it be quick to give up? For example, voice problems. Some Bluetooth earphones have a large delay, so replacing them with wired earphones may solve the delay problem that you feel the image and sound are out of sync. However, if the audio tends to be choppy and unstable, you may be able to deal with it by changing the settings of the Wi-Fi access point. "Frame aggregation" introduced by IEEE 802.11n is a function to concatenate and transmit multiple small frames (packets) with the same destination. Communication speed can be increased by increasing the transfer efficiency, but it takes time to connect frames for data with a small size such as voice. Increased transmission volume can also cause delays. Due to the specifications of wireless LAN that uses half-duplex communication, it will be in a standby state while other terminals are communicating, so if the amount of data stored in one frame (one transmission) increases, the wireless occupancy time will increase. It may become longer and the audio delay may increase due to waiting for other communication. This frame aggregation is supported by many Wi-Fi routers / Wi-Fi access points that support the wireless LAN standard of IEEE 802.11n or later. Disabling this feature has the disadvantage of reducing wireless LAN transfer efficiency, but it should alleviate problems related to audio in web conferencing apps, such as frequent interruptions and delays.
