Thread: 3G Data Connection Disconnects Frequently PLEASE HELP !!!

Hi ,I have been using BSNL 3G Data Plan on my laptop through Nokia 5800 as USB Modem.
The Speed is awesome (200-250 KBps through IDM) & Torrent Speed is arround 150KBps but problem is, it disconnects every few minutes and the download gets interrupted. The connection remains connected but Internet gets disconnected

Another thing ,this problem of frequent disconnection doesn't happen when i am browsing .So it happens only when i am downloading.

Its really irritating because i cant even download a song or a movie .

Hope you guys can help . PLEASE

m using bsnls 3g data card.. though i m in full network range.. it disconnects randomly in between .. not related to fixed amt of time or amt of data used, it just disconnects.

N seriously its frustrating to again n again make connection ... not able to download any stuff properly ..
Ya but speed is very good .. only if any one knows how to keep the connection going on ..

Please any suggestions or workaround for this !!!

The problem occurs because of a limitation in the current USB modem driver (Usbser.sys).

1. Removed Nokia PC Suite and installed OVI Pc Suite. It is the latest suite from nokia and it had latest drivers for Nokia modems. If you are using Windows 7 then this step is more useful.
2. In the modem configuration properties, change the maximum speed to 26000+.
3. Installed the microsoft hotfix patch number KB925681. See the description of this hotfix and you can understand. Its closely related to disconnection issues

Let me know if this worked for you.

i am from bangalore
I am using bsnl 3g since 3 days and today i am facing lot of disconnection problem almost once in 5 minutes... yesterday it was once in a while .....really frustrating.... I am using Huawei E 1752 unlocked , bought in bangalore for 3000 rupees from a shop near hotel leela , old airport road , bangalore...

Please somebody tell whether it is BSNL problem or data card problem

It doesnt solve the problem, as in Windows Xp SP3 they've already fixed that bug of KB925681. And more over my BSNL 3G Data Card(USB) disconnects at every 411 MB of data usage. and later i've to connect it manually to start any download.
Please share some solution.

(a)
Copy/Paste here. ipconfig /all
(b)
Download tcp/ip optimizer from speedguide.net.
(c)
Can you access the USB modem settings.?
check some AT command option/s if available.
(d)
Relocate Laptop for "LOS"( Line of sight)
(e)
Mention details of Download Manager and 3G(USB) card

Feedback item wise
