Only ISPs can change your upload speed. ISPs need to increase their default upload speeds going forward - more and more multimedia & gaming requies it.
I got 200M/bs down and 1.5 to 8 Mb/s up via wired connection to HG659 and WiFi speed (1Meter away, no obstructions), 43Mb/s down and 6.9Mb/s up, turned the Modem firewall to low as Wifi doesnt work in a practical sense (device sees modem, is connected, but speed test fails as too low to register, returns error messages).
