Oh No, What have I done

Question

After getting my dreadful speed sorted with the help of the mods I have gone and trashed it by changing routers for a BT business hub!
My speed was almost 2.5 now its only 1.2. I quickly swapped back to my old router but its made no difference,
here are my stats

Answer 1

Too many disconnects in succession ( swapping routers, resetting and switching them off etc) will have alarm bells  ringing with line management and will slow your connection down to find stability.  Leave it alone for 3 days+, it should return. 
Time of day you did this can play a part however I have always found you will get what your line can support, in the end!
