hey i have a rb433 running routeros4.5 now, upgraded from 3.30 where i had the same prob mainly its my speed feels like its capped at 70-80 kb/s doesn’t matter what program i use , even change operating system and the computer has no effect . the provider assures me that there not capping my speed and i have talked to other users, theres are fine. every now and then it spikes up to 400kb/s where it should be and if i change setting , any settings in the rb it spikes up for a while but then goes back down i have tried all most every thing even reseting the configuration a few times, i did have good speed at the beginning so any help would be appreciated
