I am trying to test with Cable connectivity and so far all of the changes I have tried have resulted in the default DSL still being chosen.
For example, using this call
runtest.php?&f=xml&location=Dulles_IE9.custom&bwDown=5000000&bwUp=1000000&latency=28&plr=0
I still show DSL on the resulting report pages. Even though the sample connectivity.ini shows Cable, the Documentation does not show that as a valid option.
Dulles_IE9.Cable should be all you need. Any chance you were using lower-case “cable”?
With the string you are using, it should display custom but your bandwidth numbers are off (send them in Kbps, so divide them by 1000). The out-of-range bandwidth values are probably causing it to revert to the default.
