We are using a Vodem K3805-z USB modem which does connect to the Vodafone mobile broadband network but the web browser isn't able to find any URL on the internet. The signal strength is 'good' (3 bars of 5) and is connecting using 3G (not GPRS). We have removed all drivers, uninstalled software, reinstalled latest software but still no better. The browser works fine when connecting to the internet via a router.
Are there any diagnostic tests we can perform to see if it's a network or account configuration problem? Does the vodem need any specific settings to allow it to work on the network and connect to the internet?
We have been in contact with Vodafone support and they say that the account is all set up correctly at their end and should work.
