It strikes me that since the changeover to Coms nobody has checked to see if the settings in the modem need to be changed. I seem to remember that ADSL24 had a page showing a list of the settings needed like VPI, VCI, Authorisation mode, Encapsulation method, modulation type etc. I can't find anything on Coms site.
I wonder if it would help if someone knowledgeable could post a full list of settings on here so that all users can check they have their modems set up correctly. I'd do it myself except I (hmph) accidentally wiped mine and had to guess lol. Come on you techies, show Coms how it's done
