Internet Connection Problem

Wobble 13 January 24, 2010 at 05:42 AM
Yesterday my laptop quit connecting to the internet.

I am connected to the wireless network and even when I connect to the modem via cable, same thing - no internet connection.

If I select repair the connection, it says it is renewing the IP address but after awhile it just says the IP address was not able to be renewed - contact the computer manufacturer.

Any ideas?

Thanks

try doing it yourself - 1. Click the Start menu button on the Windows taskbar.

2. Click Run... on this menu.

3. If the computer is holding a current IP address, type 'cmd' (without the quotes) in the text box that appears. A command prompt window appears on the screen.

4. Type 'ipconfig' (without the quotes) to view the status of the computer's IP address(es).

5. If the computer is holding a current IP address, type 'ipconfig /release' to let go of the address.

6. Type 'ipconfig /renew' to obtain a new IP address (whether or not the computer is holding a current address).

also make sure DHCP is enabled in router configuration

if the above doesnt work, restart the router and if that doesnt work, reset it.

i am having a similar problem but not entirely. my new laptop used to connect to a neighbor's wireless network. now the laptop cannot see any nearby networks (password or no password). the other, older laptop connects to the network no problem. the new laptop can connect to my own dsl line with an ethernet cable but that won't work upstairs (and is much slower when trying to download large files).

i'm guessing there is just something that happened to my network card but i'm not sure how to fix it. running windows 7 64-bit.

Doing a true power cycle of the modem and router is a good idea every month or so when these type problems arise, especially if you start experiencing these problems after you've had bad weather in your area or your ISP has done some sort of upgrade.

Shut down the computers. Remove power from the Modem and the Router -- and I mean exactly that -- pull the power cords from the outlet. Wait a couple of minutes. Plug the router back in and wait a couple of minutes for it to boot up and be ready. Then plug the modem back in and wait a couple of minutes for it to boot up and be ready. Power up one computer at a time and see how it goes.

Usually want to plug in the modem first then router. When the router comes online it will try to get an IP from through modem, if it is off it will of course fail. When the modem comes on in theory it should try again to get an IP, but it may not. Turn on modem, router then PC

Well some laptops have a switch and/or combo of keys which actually turns off the wireless if pressed. I might first look for this to make sure your wireless is actually enabled.

this is a new laptop purchased late 2009 so i am doubting there is a switch although i'll look. do dell laptops have a combo of keys to deactivate the network card? or where can i find the menu to actually activate it in windows 7?
