You may try this: Click Start > Right click on "My Computer" > Select "Properties" > Hardware Tab > "Device Manager" button > Click the "+" next to "Network adapters" > Right click on your Ethernet adapter > select "Properties" > select Driver tab > select "Roll Back Driver" button (third button down on the left side). This will work if an updated driver is at fault.
If the above fails you could then try Right Clicking on your device in Device Manager and select "Uninstall", and after uninstalling reboot and let Windows New found Hardware Wizard pick up the device and try to correct the fault. Otherwise if the Adapter is integrated you can look for updated driver at Dell's Support site, and if added on (via PCI slot) check at the adapters Manufacturer's site for the proper driver.
If all else fails, replace the Network adapter.
Good luck.

Keyboard stopped working


http://www.ascendtech.us/emachines-kb-0705-ps-2-keyboard-black_i_kbdemkb0705bps2.aspx

Things I see here.
1) The second Keyboard you plugged wasn't any good either.

2) The PS/2 port for your keyboard on your motherboard, isn't any good anymore.
Computer off, plug it into the Mouse PS/2 port, and use a USB mouse.
BIOS will reset the I/O address for that PS/2 port, and set it for the Keyboard, when the computer is turned back on.

You may have to;
A) Turn the computer off
B) Unplug from power.

C) Press the Power On button in, and hold it in for a count of 10 seconds. Let go of the Power On button. Do this same procedure two more times.

What you are doing is draining residual power, clearing CMOS Error Codes, and resetting BIOS back to the factory default settings.

Keyboard plugged in, USB mouse plugged in, plug the computer back into power. WAIT 1 minute, turn the computer on.

Still no?
Motherboard replacement.

You didn't unplug the old Keyboard, WITH the computer on, and plug the new Keyboard in, did you? It isn't a hot-swap device. The computer must be off when unplugging a mouse, or keyboard.

For additional questions please post in a Comment.

How to setup a Wireless Network


1. <b>Connect Your Wireless Router</b> <br /><b>a.</b> Power off your cable modem and your wired PC.<br /><b>b.</b> Unplug the Ethernet cable from your cable/DSL modem and plug it into one of the LAN ports on the back of the wireless router. Leave other end of the cable connected to your PC.<br /><b>c.</b> Connect another Ethernet cable between your modem's Ethernet port and the wireless router's WAN port. (The WAN port should be separate from the other grouped LAN ports.)<br /><b>d.</b> Power on the modem and watch for the status lights to indicate that it's connected to your Internet service. This may take a minute or so.<br /><b>e.</b> Plug in the router. The status lights will blink as it runs through its diagnostics; this may also take a minute or so.<br /><b>f.</b> Start up your wired PC.<br />2. <b>Configure your Wireless Router</b><br /><b>a.</b> Refer to the router's quick-start guide, launch Internet Explorer, and type in the address indicated in the guide.<br /><b>b.</b> Follow the on-screen setup wizard, which will guide you through the process step by step.<br /><b>c.</b> Enable your router's security functions. This is very important if you don't want other people attaching to your wireless signal. The options will be WEP and WPA. Both will ask you to enter a key. Depending on the router's manufacturer, you may have to go into Advanced Settings to accomplish this step.<br /><b>d.</b> Change the default administrator's password, Almost all hackers know them.<br /><b>e.</b> Change the SSID-the name of your wireless network. Again, hackers know many of the default SSIDs and can use them to hack your network.<br />3. <b>Install a Wireless PCI Card in a Desktop PC</b> <br /><b>a.</b> Refer to the card manufacturer's quick-start guide. If necessary, run the software installation program.<br /><b>b.</b> Power down the PC.<br /><b>c.</b> Remove the cover.<br /><b>d.</b> Find an available PCI slot and remove the slot cover from the back of the PC.<br /><b>e.</b> Carefully insert the antenna through the open slot in the back of the PC, carefully push the card in the slot, and secure it. Replace the cover. <br /><b>f.</b> Start up the PC. It should recognize and install the new PCI card.<br /><b>g.</b> Go to the Control Panel, select Network connections, select Wireless Networking connection. Click on Properties button. Click on Wireless Networking tab. Select the wireless networking name (see step 2e). Click on Configure button. Configure your security settings to match the ones on your wireless router.<br />4. <b>Install a Wireless PC Card in a Notebook PC</b> <br />Many notebooks have built-in wireless cards. However, If yours doesn't, you can install either a USB wireless adapter or a wireless PC card just follow these instructions.<br /><b>a.</b> Refer to the card manufacturer's quick-start guide. If necessary, run the software installation program.<br /><b>b.</b> Power down the PC.<br /><b>c.</b> Plug your USB wireless Adapter or wireless PC Card into an available slot on the side of your notebook.<br /><b>d</b>. Start up the PC. It should recognize and install the new PCI card.<br /><b>e</b>. Go to the Control Panel, select Network connections, select Wireless Networking connection. Click on Properties button. Click on Wireless Networking tab. Select the wireless networking name (see step 2e). Click on Configure button. Configure your security settings to match the ones on your wireless router. well, thats pretty much it. Hope this is helpful to all you home networkers.<br />

Wifi modem is not recognized


Try recycling the wireless router by unplugging the power to it and wait 20 seconds then plug the router back in. Sometimes that is all it takes.

After recycling the router if the adapter still does not show any wireless networks make sure you don't have the wireless radio turned off in the software that runs the adapter.

If all fails, try the adapter in another usb port if it is a usb adapter.
You could reinstall the adapter's software and driver.

Emachine doesn't recognize the ethernet cord when plugged in


Sounds like the integrated ethernet port has gone bad. You can install a new ethernet card in one of the PCI expantion slots. Then plug the ethernet into the new card, this should take care of the problem. You can not repair a bad integrated ethernet port.
