Hi there
Sorry for my late reply - life got in the way
I've not just used bredbånd.dk - actually I've used a lot of tests, but it seems many are based on Ookla. I've also tried the swedish bredbandskollen.se, wich sometimes indicates upload problems though the speed seems alright. It wanted me to try another browser, but the situation was the same. Normally I use Chrome, but for testing purpose I also use IE.
Right now my results from TMN is 115/12,3 - at bredbandskollen it is 124/28. My ping is typically over a 100 ms.
