Wireless connections tend to be quite a bit slower than wired connections due to the way the packets are transmitted. A wired network is full-duplex, meaning that both transmit and receive happen at the same time. Wireless are half-duplex, meaning that either or operation happens, so the network is slow.
When downloading from Auran, they recommend using a download manager. This is particularly helpful with slow connections as it helps to prevent data corruption on slow connections.
