Windows 7: Losing my internet connection

Windows 7 Ultimate x64 SP1
Losing my internet connection

Hi.Im having problem with my internet.Im using wired connection but without router/modem.It's a usb internet flash drive.The internet provider is from Bulgaria MaxTelecom.My problem is that when i connect the usb in my pc it connect perfectly until i try to open web site in the browser.When i open the browser the internet dropped immediately and after 5-10 sec reconnect automatically.

In event viewer i get warning and error:


"Name resolution for the name(the web site im trying to open) timed out after none of the configured DNS servers responded"


"Your computer was not assigned an address from the network(by the DHCP Server) for the Network Card with network address 0x001D9316A2D3. The following error occured 0x79. Your copmuter will continue to try and obtain an address on it's ownfrom the network address (DHCP) server.

The usb internet flash drive is working excellent in every pc and laptop i tried but not in mine. Sorry for my bad english.

Hi, Welcome to SF.

You may follow the steps.
a. Click Start.
b. In the search box type cmd
c. Right click cmd and select Run as administrator.
d. Type the following commands and press ENTER.
ipconfig /release
ipconfig /renew

Also, scan for virus. Run antivirus and Malwarebytes. Disable IPv6. If this resolves, good.

They should be something like 192.162.x.x

Have you tried to uninstall and then re-install any drivers or software related to the mobile broadband connection? This may be worth a shot...
