Adding myself to list of those with "upgraded" superfast plan with no actual speed increase   Interestingly though, my upload speed has been reduced from 40mbps to 25mbps as advertised...   But my 100mbps download speed hasn't increased   Like others, have tried changing wireless from "auto" channel to specific channel and no joy..  Have rebooted the NBN and TPLINK routers with no change...   Note there's no interference near us, so pretty much all channels are ok..   I have the Archer 1600v like most people...   any help thanks!   ...
