K3520, Widnows 7, disconnects

[Xyber]

I am typing this hoping the modem won't be disconnected again in the... oh.. wait.. there it goes, so anyway...

I am using a K3520 with Widnows 7 and OSX (snow leapord). On windows I get disconnected every few minutes and then have to exit the mobile connect software, unplug the modem and replug and start software before I can make a connection again. The signal strength bars are showing as full/excelent in the software. To make things worse, on OSX I don't experience these disconnects and went 3 days straight without a disconnect.

So where is the problem? Do I need some kinda new drivers for the thing under windows, or a firmware upgrade? I've been testing with the software that comes on the stick and latest Mobile Connect v 9.4.4.17702 I could find on the net.

[edit] I noticed that with Skype on I get these disconnects, while without it the modem seems to stay connected. Gonna leave Skype off a bit a do further testing.

I had a similar issue with a client, used the VMC that came with modem. I installed VMC 9.4 from Vodacom's Website and seemed to fix the issue. Maybe try that?

is the K3520 the ZTE or Huawei one? If Huawei, download the Hotfix for Windows 7 on Vodacom's Website too.

Is your Internet Options ->> Connections set to Never dial a Connection ? If not, set it to that then try it with Skype again.

I am on v9.4. Spotted that hotfix in another post, will try it and your other suggestions and see how they work in combination with Skype. I've had Skype off for about an hour now and had no disconnect.

Still no luck with Skype on.
Its the Huawei K3520
I installe the hotfix, running latest mobile connect 9.4 and checked the internet options->connections

Doesn't matter too much though, at least now I know it was Skype causing this and will just keep it turned off till my DSL line is activated.

Its weird though. I have a K3520 as well. Also logged on to Skype all day. I dont get any disconnections.

Only difference is, You're running Windows 7, i'm running Windows XP Service Pack 3.

Perhaps re-install your copy of Skype? Or update to the latest version?
