Changing the channel has worked wonders

Tried a few channels and can get around 10Mbps constantly now, so it only takes a couple of minutes to transfer the files
The only problem is moving from channel 6 limits it to a 54mbit connection rather than the full 108mbit (not that im getting anywhere near either still

) Could it be my cordless phones interferring on channel 6? Or all the neighbours networks? (Can see a couple of others in the available networks but its a big detatched house so I guess they wont be too much of a problem?)
