I had problems connecting to an my internet on my home desk pc.

My external modem has a built in router which I can connect to different pcs just fine (wireless as well as thernet connections)

After several attempts of troubleshooting I tried to reinstall the operatind system, however when I tried to run my interbet wizard it could not detec the modem.


Does this mean the thernet adapter need to be replaced?

In my device manager there is no question mark next to the ethernet adapter.

I also tried reinstalling the drivers for the ethernet adapter.

Any suggestions?

If the proper driver won't install, then I think the ethernet card is no good.  Ethernet cards are relatively inexpensive to replace, so try a different one.

Ethernet cards are very easily damaged - a voltage surge in a cable can knock out any card it is connected to.

If the ethernet card is wired:
Before you replace the card, check (with the computer running & with the ethernet cable connected to both the card & to the router) if IT THE (GREEN) LED LIGHTS ON IT ARE ON OR OFF.

If lights are on, the card is most likely good. If off & the router works fine, then possibly  bad card or a BAD CABLE. You can try swapping a cable you know that works, but I doubt that the cable is the problem.

But first:
>>In my device manager there is no question mark next to the ethernet adapter.
This suggests that the card may be good.
Please tell us the name of the card that you see listed in device manage. Then I can help some more. Thanks.

Also try this first. VERY IMPORTANT to get internet working:
In Internet Explorer:
Tools -> Internet Options -> Connections -> LAN Settings
Make sure "Automatically detect settings" has a CHECK
Make sure "Use a proxy server" is UNchecked.

Appears that driver for NIC is not installed.  If you have driver that came with card, install it.  Otherwise will need to download correct driver.  We'll need make and model to help further.

This utility will help identify NIC (Everest Home):

A "?" in Device Manager usually means you need to install the driver.
You said "I also tried reinstalling the drivers for the Ethernet adapter." before. So I assume you have the driver on a disk or CD? if not, try driverguide.com or the company's website. But see first if the  card has its led light on or not.

Well, I may have a simplier solution.  I had a Dell computer come into the shop with the same problem.  After a little bit of troubleshooting, and reloading the drivers for the (onboard) ethernet connector, I still couldn't get a connection.  While I was running thru basic troubleshooting procedures,  in this case double checking the cables I notice that the light on controller was not lit.  I finally figured out that the controller was disable in the BIOS.  Once I enabled it, everything worked fine.  I guess I broke the golden rule of computer repair... assuming that the device WAS working at one time....  This customer was on dialup for years and never used broadband before.

One other thing that has helped over the years..... powerdown and restart the router.  Sometimes when adding or switching the broadband connection to computers some router need to be reinitialized.  Hope it helps

OK so I added a new ethernet.

Reinstalled the operating system.

I need to down load the drivers for this. Do I need to download USB drivers too?

When I tried to transfer files from my USB jump drive to my desktop it could not detect it.

You may need to install chipset drivers for your motherboard.

After a clean re-install of Windows, any drivers not included in Windows must be installed.  Although Windows may recognize your chipset, it usually does not have the latest specific drivers.

Flash drives do not require separate drivers in Me, W2K, and XP.

How about some information first such as what brand/model of your PC and/or motherboard.

If you need help in identifying components, download and install Everest Home.

Might as well split the points based on shared solution. I got lost in the moment, quickly typing to fill the current need without realizing & crediting willcomp's past post.

But here's something related & curious:  http://www.experts-exchange.com/Q_21919676.html Windows XP: MSINFO32 --> Software Environment --> Startup Programs HUGE GIGANTIC BIG LIST ?!

Made the same apparent mistake there -- researching & posting a solution without re-acquainting myself with the whole long-winded and 10-days-old thread, and then receiving a rebuke for the double post. BUT, it may never have got solved otherwise lol. Asker said: "I'm an idiot... If it wasn't for callrs, I would have totally missed the post sramesh2k made!  @sramesh: THAT WAS IT DUDE :)". I never got part credit for that :-p
