network hardware problems

[H2SO4]

The computer I am using right now has network problems. Me and my friends used to hook the xbox into our RJ45 jack on the back to play xbconnect. I also used to connect to my modem via ethernet. Then one day my ethernet didnt work anymore. I was suprised to find that it wasnt a card in my computer, but i think it is integrated. This is a bummer, i wanted to just take it out and place it in another slot to try to fix the problem.

 

Now i connect to my modem via USB 2.0, which isnt as fast as ethernet for networking. I am getting a laptop soon and im going to need that ethernet.

All the lights on the RJ45 work, and when i plug into a network, they pick it up. But it stil doesnt work. When i go into task manager, it tells me "no active network adaptors found". I counld even get the slightest connectivity. I tried pinging sites. nothing.

 

The modem came with a "LAN" cable, which worked, then stopped. I also tried to connect it with a cat.5e patch cable. Still nothing.

 

 

Im going to try to reinstal the drivers. I went into bios and didnt even find anything for the networking hardware. What would this piece of hardware be called? And what can i do to fix it. We wil probaly end up calling dell to have them fix it (its still under warranty), but i want to learn on my own.

Alright, i found in device manger my ethernet controller is missing a driver. I hope the "ehternet controller" is the problem. i Cant seem to find a driver with the resource disk's i have. Will any ethernet adaptor driver workk with different brands?Or do i have to find the driver for this brand or watever?

Ok, found it. Ended up being a driver problem. I had to install the driver from a resource disk. I noticed i have a few other pieces of hardware that dont have drivers for some reason, so now il find them . Heres one of the driverless hardware's:Multimedia Audio controller. Ive never heard of this piece of hardware.

ok, now i need the driver for my multimedia audio controller. I cant find it with my resource cd's or my sound card software. It seems to be a common problem, from what ive seen in google searches.
