It is highly recommended that the user research how adjusting the MTU may affect network traffic for better or worse. Similar to the MTU, except this applies to Maximum Received Unit size for downloading data. Most users will be happy with the default setting (1492 bytes). However this may also be optimized for fast downloads of general bulk Internet traffic, for low latency or for downloading to computers on the Wireless LAN.
