Cannot connect to internet using usb modem with laptop IBM Thinkpad R400.


ZTE modem is detected but intermittent?

This to me falls to a hardware problem, and not a software problem, HOWEVER, let's discuss the driver issue anyway, and first.

Where are you installing the driver from? Device Manager? Pggh!

Windoze lost the address to the driver file anyway. I find Device Manager a waste of time. A hit and miss proposition at it's best.

Download from Lenovo Support AND install. Have a lot of people on here that seem to think you just download the file, and that's it.
You have to INSTALL it also.

Now to the hardware part;

http://support.lenovo.com/en_US/guides-and-manuals/default.page?

Under the red banner with - Guides and Manuals - in it, click on the black - Hardware maintenance manuals - heading.

Click on the blue -> { + } Click for files

Now click on the blue -> Hardware Maintenance Manual

This is a PDF file. The computer you are using now has Adobe Reader on it, which uses PDF files.
After you click on the file name it may take up to 30 seconds, before the first page comes up.

The plus + icon at the top of the PDF viewer is for Increasing the view size.
Click on the minus - icon to Decrease view size.

Go to the Bookmarks menu to the left, and click on the + sign to the left of -
Removing and replacing a FRU
(Field Replaceable Unit)

Scroll down using the blue Down Arrow.

There are two mini-WiFi modules in your laptop.
1) 1090 PCI Express Mini Card for Wireless LAN/WiMAX

2) 1100 PCI Express Mini Card for Wireless WAN

Both of these modules have two antenna cables, that connect to them. The terminals on the modules, and the connectors on the cables, could have corrosion on them. Suggest clean. Make sure the connections on the modules are tight. (DO NOT overtighten!)

Could also be that one of the modules is going bad.

Cant use my usb



Refresh and reinstall USB Ports Of Your Computer Hello there, the other day i tried refreshing and reinstalling the USB ports on my PC, as some of my connecting devices are not recognized. I present the detailed procedure on refreshing the USB ports.
Let’s go!!

Here are the steps to refresh/reinstall/uninstalling the USB ports on the computer.

The USB port needs to be refreshed to make sure that no other device has captured the USB port of the computer. The Mouse, video camera, your external USB hard disk; what ever it may be.

Follow the steps given below to refresh USB ports.

1. Right-click My Computer icon on the desktop, and then select Properties.
2. Click the Hardware tab.
3. Click the Device Manager Button.
4. Click the plus (+) sign to the left of Universal Serial Bus controllers.
5. Right-click the device listed under Universal Serial Bus controller and select Uninstall.
6. Click OK to confirm the removal of the device.

Please note, repeat Steps 5 and 6 until all the devices under Universal Serial Bus Controller are removed.

7. Shut down the computer.

CAUTION: Ensure that the Shut Down option is selected, instead of the Restart option.

8. Wait for 5 seconds and then restart the computer. When the computer restarts, a "Windows has detected new or added hardware" message window will open.

The above steps will refresh the USB ports.

Now connect the USB devices like mouse, video camera, your external USB hard disk...USB hubs...whatever you like and the drivers should install automatically.

Tip: It is always recommended to connect the main USB devices at the rear end USB port. As they require more power to initiate.


The above steps are for XP operating system. When coming to the matter of Vista, please note the changes below:
===========================
1) Right-click Computer icon from the desktop , and then click Properties to open the System Properties window, and then select the Device Manager tab.

2) Click the Plus (+) sign next to Universal Serial Bus Controllers/Root hub.

3) Click the USB Composite Device entry to highlight it, and then click Remove. If a screen appears to confirm the deletion, confirm the deletion.

4) Disconnect the USB cable to the all-in-one, wait a couple seconds, and then reconnect the cable. This should restart Windows device detection (Plug and Play).

5) A New Hardware found screen may appear, click next through all of the screens that appear for the Wizard to install the USB Composite Device. Click Finish once the wizard completes.


If I could be of further assistance, let me know. If this helps or solves the issue, please rate it.
Thanks, Joe

Hardware detection problem


Can you explain a bit better? Sometiems it's detected, but there's no detection?

Try plugging it back in. Go to Start: Run: devmgmt.msc orStart: bar at the bottom, type devmgmt.msc ... Look at your devices, look at whether anything has a warning sign next to it.

The ethernet port is not working, and the network card is not being detected in device manager


If the device manager is not detecting the network device it is not going to work. turn off the laptop and remove the network/modem device located on the bottom of the laptop, then restart the laptop, now shutdown the laptop again and reinstall the device restart the laptop if device manager still does not detect the device then it is defective and will need to be replaced.

USB powerloss?


As you have already stated that the port in question can run a standard optical mouse, the port seems to be working fine.

Sometimes the drivers for a USB device need to be installed for each USB port. Maybe you have installed these drivers for 3 of your 4 USB ports, but not for the one in question, result of which is the problem you face.
