Recently the bt adsl checker has started listing that I can get 17mbps over WBC ADSL2+. I have always been told the my line length is 5000m therefore wouldn't be able to get more than 3mpbs, which is what I have been getting for the last few years. My isp confirmed that I'm on WBC adsl2+ and have a line length of 60db, which would make my 3mpbs sensible.
My ISP is suggesting that there could be 2 routes for me getting to the exchange and that I'm connected to the longer route? given that I'm not getting the 17mbps that BT are listing on the checker.
Also I know that I was being served by a TPON cabinet (20yards form my house), however recently a OpenReach engineer said that the cabinet was no longer in use and that all the connection were done in the, recently extended manhole, next to the cabinet.
Is there any chance that BT would re-route me to the shorter line?
The ISP as arranging a engineer visit.
