Thanks for coming back to us, I am sorry to hear your getting low upload speeds, when you are checking this are you using a wired device with a gigabit network card using a Cat 6 or above ethernet cable.
While doing this you need to put your router into modem mode and removed everything else other than one device using speedtest.net.
Thanks for your response. I've done this already. Pc, with 1gb cat6 cable, right next to the router - still 0.05 upload. Looking at the BB pages, it seems to be a common complaint over the last couple of weeks. Seems like a case of VM throttling services back.
