Adjusting B315/B618 APN for Cell-C
To log into the router you will need to type 192.168.8.1 into a web browser. The default username and password will be admin/admin but you will only be prompted for that once you select the Settings option.
Once on this page select Settings and enter the above mentioned login details.
The B618 will request a password change which you can just go along with.
Once logged in you will select Dial-Up on the left of the screen.
Select Profile Management and then New Profile.
Enter a name, it’s just a placeholder so for short just call it CellC and then importantly enter lte.broadband.is in the APN section. After that make sure the profile is selected, then you can hit Save and Apply.
That should bring you online!
