But several years ago, it was turned off because of stability issues on a few wifi chipsets. It used to be "on" by default in the iwlwifi driver. Thus it sharply reduces the amount of transmission overhead. The purpose of AMPDU is to improve data transmission by aggregating or grouping together several sets of data. If so, you'll probably be able to increase its speed noticeably, by turning on Tx AMPDU for it. If you have a (reasonably) modern wireless chipset from Intel, it'll run on the iwlwifi driver. Then check in the terminal, by the command iwconfig, whether Power Management for the wireless chipset is off now.ġ0. In that text file, you see the following content:ĭ.
