It will certainly not be possible to reach 5 gb/s for a long time yet. With Sunrise 5G, I usually have 400-500 MBit/s down and 40-50 Mbit/s up. Sometimes faster, sometimes a little slower. But I have always achieved well over 100Mbit/s down.

According to the speed data on the Sunrise website it says I have 17Mbit/s down and 1Mbit/s up, which is absolutely not true and I don't know where they got these values from.
