Error 633: Modem already in use or not configured properly
I am using a Windows7 Home Premium 64 bit PC.
When i am trying to connect to internet using 3g USB modem, i am getting Error 633: Modem is in use or not configured properly.
The software and drivers were installed properly. I uninstalled and re installed several times with no success. I tried the same in Safe mode without success.
I would also recommend you to connect the modem to a different computer and check if it detects over there. If it is not working on a different computer also, then the problem will be with the modem and I would suggest you to contact the modem manufacturer
for getting any further assistance.
