Got mine sometime this weekend. Not sure when though, on Sat morning I was still at old speed, this morning now doubled (did not bother checking in between). Must say that I have not noticed any difference though.
Mine also weirdly kick in. On 50/5 Axxess/Vuma. Looks like Axxess isnt giving me the speed. Downloads from the likes of Steam, Uplay stop at around 5.5MB/s. The same as i used to get.
Test On Vuma Speedtest.
