Cannot connect to internet router is working properly it is connected to my regular computer but cannnot get singal for my notebook
First thing, make sure your WLAN card is turned on, however, without knowing your specific laptop model, I can't help locate it for you. After that, check your router's wireless security code, and assure that you're entering it correctly. Then, if you still aren't able to connect, try manually unplugging the ethernet cable from your PC, then plug the Ethernet cable into the laptop. If you get a signal, skip to the third paragraph, if not then read the next paragraph.
If you aren't getting a physical connection, it could indicate that there is something wrong with some type of software, or operating system settings that aren't allowing you to connect to the internet (leave the network cable plugged in for troubleshooting). Try checking firewall settings (windows firewall is infamous for blocking almost all connections at will). Then, if you're using windows xp, go to the start menu, open the run command, and type "CMD" without quotes (if you're using Vista or Win7, then just type CMD in the search box at the start menu. When the command prompt screen appears, enter this text without quotes "ipconfig /all". If you have an IP address, subnet gateway, and IPv4 configuration, then you're ready for the next step (if not, let me know in a comment, and I'll leave the instructions for that solution). If you're using xp, then right click computer, click properties, go to the hardware tab, then click "Device Manager" (for Vista/Win7, just type Device Manager in the start menu search box). Scroll down (if you have to) to Network, click on it, find your physical network card, right click and uninstall it (don't worry, this won't hurt anything). Wait for a few moments, then right click anywhere in the Device Manager window, then select "scan for new hardware". This will find the NIC you just uninstalled, and reinstall it (with original drivers, unless you've upgraded your Operating System, then you'll have to get the drivers from the manufacturers website via your desktop). Reboot the laptop, and try connecting with the LAN cable again. If this solution doesn't work, leave me a comment describing what you've done, and any error messages that have come up.
If you recieve a signal from the LAN cable, and still cannot connect via the wireless card, then back into device manager we go! For xp users, go to the Start Menu > right click Computer > click Properties > go to the Hardware tab > then click Device Manager. For Vista/Win7 users, open the Start Menu, then type Device Manager. Scroll down and find your wireless card, and if you've tried the solution in the second paragraph, you know what we're gonna do. Right click it, Uninstall the wireless card, wait for a few moments, then right-click anywhere in the Device Manager screen, and select Scan for New Hardware. Reboot the system, and you should be working!
