Sorry in advance for my messy format, its just that i have alot of things i'm confused about right now and i would really want to get them sorted.

Long story short, after moving to a new address a month ago and having trouble getting our internet connection to work on any phone jack, my ISP organized a chorus technician to inspect the problem for us and located it to be a filter/splitter(master?)  installed in the box(phone line?) on the wall inside our garage. He told us that the filter would only allow one jack plug to connect to the internet, that jack is strangely located inside the box. He told us he could either connect the splitter to a specific jack point inside the house or bypass it so that all jacks can connect to the internet. As we have only just moved in and was unsure with jack point we would like to use, we opt for the second option.

The chorus technician kindly removed (and took away?) our filter without charge. What he did not tell us was why we should keep the filter..... 

So from what i understand after some self reading online, installing a master splitter would reduce the noise on the wiring inside the house hence give a better connection especially for houses with several phone jacks(in our case 6~8)? Also with a master splitter installed, addition adsl filters are not required for the phones and modems?


We have adsl2+ filters for every device plugged in a phone jack, how much of a difference would a master filter make?

Master filters can be bought for a rather low price but installing them seems to require a fair amount of knowledge and some connectors? The cost of getting a technician to install one costs somewhat between $150-200？

I feel really awkward as if a master splitter is needed, we will essentially be paying for something to be installed that we just got removed...

Cheers
