K3760 Regularly Dropping Connection

[golfather]

I have had a K3760 USB modem for a few months now, and it has been working successfully on my XP Laptop.

However, recently I have been having regular connection problems with this modem.
So I carried out the firmware upgrade process for this USB modem, detailed here:
http://forum.vodafone.co.uk/index.php?showtopic=25736

But this has not improved things.

What is happening is that after connection, around a few minutes later, the connection will disconnect, and Vodafone Mobile connect will report that No Device found.
I then have to close down Mobile Connect and reopen for it to recognise the modem again and reconnect.
Then again it will disconnect after a few minutes.

Can anyone please assist as this is now becoming unusable!

Version numbers:

Vodafone Mobile connect Lite: v9.3.6.12095
Device: GlobeTrotter HSUPA MOdem, 1.5.0.0Hd

Many thanks

Hi paul oneill,

Welcome to the eForum and thanks for posting about your dongle here you've come to the right place. I'm sorry to hear you've had continued problems with the connection. As you mentioned you have travelled around a fair bit and get the same result this strongly suggests to me that there may be a hardware fault with the dongle itself.

Have you let our guys at the Vodafone Repair Centres take a look at this? It's free and within the manufacturer's warranty but to be honest I am surprised you are getting connection problems repeatedly. If our engineers deem the device beyond economical repair then we will replace the device.

Let me know how you get on with this.

Thanks,

I held off returning this - as I was intending to try this with a new laptop. I re-checked this with a Sony laptop running windows 7 (using the latest software) and experienced similar results. Finally the computer is now reporting that the K3760 device has malfunctioned, and I cannot get online using this kit.

Separately I have also tried a dongle that I borrowed from work, running on BT Business Mobile Broadband. This service actually runs on the Vodafone network - and it works way better than my own kit - no dropped connections!

Therefore having eliminated all of these potentially contributing factors laptop/software - its now time to return the dongle, to see what can be done with it. I have returned it through the local Vodafone shop - and look forward to getting it fixed or a suitable replacement.

Will post in due course when I get the kit back again!
