New 150 Megs optical slower then 10 Meg phone
 

Just had installed smoking optical cable...when I check my speed, lets say by Okla speed test ( and others) I do get indeed between 140 to 150 megs....but trying to get to anything is worse ( slower) then the old 10 meg connection...I have an inhouse network ( same as before) and have no clue what may cause this...Anybody any suggestions ??

I know when i get internet in it takes a few days to settle so could be that?
