abaroudi got a reaction from mudmanc4 in Confused by three test results
Okay, after looking more closely at the results I think I've realized my problem here.
Speedtest and Testmy are measuring my speed in Mbps (Megabits per second). While Fast.com is measuring in MBps (MegaBytes per second).
And so in fact the landlords are actually providing me with 1.5 Mega Byte download speed rather than 10 Mega Bytes as they told me.
