Error 608

This error happens when your computer can’t recognise or detect your USB modem. This is usually caused by a faulty, corrupt or outdated modem driver. Updating or reinstalling these drivers usually fixes the error.

If you don’t feel comfortable running through the step-by-step guide yourself, please contact our Tech Support team for help.

Checking the drivers for your USB modem

Step 1
Depending on your version of Windows, this step will be slightly different.

If you're using Windows 7
From the ‘Start’ menu, right click ‘Computer’ or ‘My Computer’ and select ‘Manage’.

Step 2
Select ‘Device Manager’ - This may be under the 'Hardware' heading or on the left of the control panel window.

Step 3
Under ‘Network adapters’ check if there is a red 'X' next to any of the Huawei drivers. If there is, right click and choose ‘Enable’.

Step 4
In ‘Device Manager’ check if any of the icons have an exclamation mark (!) next to them. If they do, this means that the drivers aren't installed properly.
Right click on any Huawei drivers with an exclamation mark and choose 'Update Driver Software...' if it's available. If not, select ‘Properties’, click the ‘Driver’ tab at the top and select ‘Update Driver...’.

Step 5
To update the driver, you’ll first need to know where the driver's installed. Choose ‘Browse my computer for driver software’ and click on the ‘Browse’ button.
The location of the driver will vary depending on which USB modem you’re using:

 
K3765/K3715 C:\Program Files\Vodafone\Vodafone Mobile Connect\Driver\pccard\vista\32bit\Huawei (Replace 'vista' with XP if needed. For Windows 7 users, the folder will also be called 'vista')
K3571-Z C:\Program Files\Vodafone\Vodafone Mobile Connect\Driver\ZTE\K3520Z
K3771 C:\Program Files\Vodafone\Vodafone Mobile Broadband\Driver\Huawei
K4511 C\Program Files\Vodafone\Vodafone Mobile Broadband\Driver\Huawei
 
Make sure to tick the ‘Include subfolders’ check box.

Once you've finished updating the drivers, try connecting to the internet.

Important information

• Making changes to your computer and its settings, outside of those mentioned in the guide above, could cause other connectivity issues. If you're unsure, please contact us for help

Error 631

If you’re getting error message 631 ‘The port was disconnected by the user’ when you try to connect to the internet with your USB modem on a Windows computer, this usually means one of the following:
• There isn't enough power getting to the modem
• Insufficient coverage
• Corrupt or missing files

Try the following three troubleshooting steps to quickly fix the issue:
1. If you're using a desktop computer, make sure you're using a USB post at the back of the computer and try to connect. Or, if you're using a laptop, move the modem to a different USB port and try again
2. If you're using a laptop, move to a different location, for better reception, and try to connect. If you also have a Vodafone phone, use it's signal strength as an indicator for a good place to try connecting
3. Change the modem's network preference to 'GPRS/EDGE Only' and try connecting. If that works, the error message was due to poor coverage. Make sure you change your network preference back to automatic if you move locations

If can't connect to the internet after trying these three troubleshooting steps, please follow the step-by-step guide below.

Error 633

How to fix it

There are three possible solutions to the problem, which we’ll step you through below:

Error 635 or 619

If you're getting either error message 635 or 619 when you're trying to connect with your USB modem, it usually means the wrong connection profile is being used.. It's an easy problem to fix.

There are two preset connection profiles. One for prepaid accounts and one for contract (postpay) or month-to-month accounts. If the wrong profile's used you won't be able to connect. This could have happened because:
• The incorrect profile was selected during installation/setup
• You've changed your account type (moving from a billed account to prepaid for example)
• The setting in your software has been changed accidentally

Only connected today?
If you've only just signed up with us, here are some things to check first:

Have you only just connected? It can take up to an hour for your account to be enabled after you first sign up. Give it some time, and try connecting again.
If you're prepaid, do you have credit? If there's not any data included with your new service, recharge with a recharge voucher or credit card using our express recharge service,or by logging in to your My Vodafone account.
Do you have coverage? Your coverage is indicated by the green bars in the Vodafone Mobile Connect software, or the light on your modem. You can check whether you can expect to have coverage where you are using our online coverage checker.
