ok , not an expert, but as I understand it
- 2 factors are at play here, the notional 'speed', which is the maximum that can be sent/received by the router, and the 'duplex' setting.
- 'full duplex' can both send and receive at the same time & should achieve 'near' 10 meg
- half duplex, however, can only send or receive, but not both at the same time, so the device has to wait for the 'ack' packet to be sent/received before sending or receiving the next data packet.
This effectively halves the download speed, as many (older) routers have half duplex wan ports.
