Hi, I"m connected to the Internet through Comcast Cable I have a Linksys Wireless B Router that is currently connecting 3 desktop PC's. Two.PC's are connecting to the internet. One PC is not, as-of yesterday. I don't know what happened to lose the connection to that 1 PC while the others are still connected. I played with my PC and did what windows told me to do. First, when I did the start/run/cmd/ipconfig, I got all the addresses (physical, IP, Subnet Mask, Default gateway, etc). Then, I lost all that. I lost my internet connection completely on that 1 PC. There is no network adapter anymore. I called Comcast and they could not tell me how to configure an IP address or how to reinstall a network adapter. They told me to call Linksys. I did and they wanted me to pay for their support since I've had my Router for some time now. For a few bucks more, a new router can be purchased. Trouble is that I don't have the money right now. Can you tell me how to get my ipconfig back? Sandy

"There is no network adapter anymore." That is where you start. Go to device manager and see under network adapters see what is listed. Is your nic builtin or an add in card? This can be a sign of malware/virus infection or the nic has physically failed.

Maybe the nic shifted a bit in the slot?? If built in, turn off system and remove ac. Using ESD controls reseat the adapter and be sure it is in the slot correctly. Then return ac and power up and try with all covers on. Playing to the angels Les Paul (1915-2009)

Allow me to translate: "If built in, turn off system and remove ac." Translation: open the case and determine if there is a slot for a video card [usually pci]. Buy the card, disconnect the power [ac=air conditioning or alternating current which in this case alternating current would be applicable] and install the card. Go into the bios and disable the onboard video. Boot windows and install the video card drivers. "Using ESD controls reseat the adapter and be sure it is in the slot correctly." Translation: if not a built in card but an addin card, disconnect the power and open the case. Using Electro Static Discharge protocols [just touch the metal in the case to equalize static between you and the hardware]. Remove the cards mount screw and pull the card. Confirm there is no dust in the slot and the card gold fingers have no green/oxidation on them. Reseat the card and screw down in place. Close the case up, connect the power and boot up.

check to see if the cable can un-pluged from the computer, I would re-seed the cable.

The adapter was missing from the Device Manager. The NIC is built in. I don't know what ESD controls are. I ended up buying a new router which did not fix my Internet connection. Called the PC manufacturer who told me to go buy a PCI Network adapter. I followed the instructions and installed it. Now I have 2 connections and Windows is seeing the Realtek Adapter along with my new adapter. However, that connection is not working completely and I have to disable it. My system is now screwed up. I have no sound anymore and my computer won't let me network. 1) It tells me to contact the administrator (that' me) to let me know if I have access permission. 2) McAfee is not working. I'm going to try and reinstall it. 3) I don't know what to do about the sound except to reinstall my Creative SBAudigy software. 4) Though I have no sound, the speakers make loud buzzing noises at time which might be due to the network. I just want to be able to see my other computers now on the network. The 2 other computers CAN see the one that's not working right. I don't know what to do with the onboard NIC. I will be away until Wednesday and attack the problems then.
