Problem with USB Ports

[jpchint]

I'm facing too slow internet speed say 3-5 KBPS. But my normal speed is 50-60 KBPS.

Type of Connection :2.G Dial up connection with Nokia USB Modem(Cable Connection) with nokia mobile(Asha series).
There is no problem with internet while surfing in mobile,but with dial up connection with laptop.

After several experiments,I had found the cause of less speed is with usb ports.I Had attached three of usb ports to mobile(via cable),usb mouse and usb keyboard.

Changing port of usb cable with other usb port say mouse replacement had caused increase in speed but only for short time.
Again replacing the usb cable with original port had also caused change in speed but its also for a short time.

I had also scanned for hardware changes in device manager but dosent solve the issue.

Also all of my USB devices are hanging during browsing internet,but this problem occurs very rarely,and i should restart the system.

I had uninstalled and reinstalled modem software in device manager but dosent solve the issue.

The problem is like hell,any help would be appreciated!!

JP first up mate what model Lenovo is it - difficult to find drivers without knowing it as I think you need the drivers updating for the USB and the network adaptor.

I suspect you have updated them using th Windows feature which to be honest I wish they would get rid of because I get all drivers from the manufacturers of the equipment / device - so much more reliable.

The issue with speed I cannot figure out what it has to do with the USB ports to be honest.

One thing you can do is to power off the modem and leave for about a minute and then power on again. This works for me when my modem (very occasionally) decides to go walkabout.
I would also run these when you get a chance to

Also do you have any cleaning programs on that machine such as CCLeaner which does a good job of decluttering the machine of temp files cookies etc?

Ok have got the model the dial up my friend I can only assume like any dial up connection it will be slow and I take it that like some places out here it is the only alternative.

It might improve if the drivers for the network adaptor can be updated but I ma not holding my breath for much.

I am also guessing the modem needs updating to but unless you can Google the model and get to their support you will have to let us know that too.

I am going off-line just for a little while so please be patient.

In the meantime go down this list to the network adaptor driver and click on the one for 7 64 & 32bit systems
