My router wont connect to internet. i have a valid internet connection. i reset the defaults on the router. it will connect wirelessly to my laptop but wont connect to internet.

The wireless cards in the computers need to be configured with the router's wireless settings so the computers can connect to the wireless router.
Resetting the wireless router back to the factory defaults will not let the computers connect to the wireless router without configuring the network card in the computers with the router's wireless settings.
I suggest you configure your wireless router with encryption settings to prevent unauthorized persons accessing your wireless network and Internet connection and your computers.

Pls try this following below and just cool down and read through,

Physical causes and What to Do...

• Network card could be faulty or malfunctioning, or the port on the card itself. Make sure lights show on the card and if they don't, replace with another one that works.
• Check that your router or the server is turned on so that the laptop can acquire a valid IP address.
• Double check to make sure the wireless card on the laptop is turned on. Do not assume it is on by default, do it yourself.

Logical or Software causes and solutions

Many of us are online buyers. Items sold on the internet, especially used items, are not in their default settings. Previous owners do not always reset them before sale, and this causes a lot of issues and unwanted beheaviours. Below are some of the common settings found on Routers:

• ISP user name and password. If you want to connect to the internet check with your ISP to get your own User name and password, if not ignore this step.
• Looking at the security options, make sure:
  • MAC address Filtering is not enable. If it is, remove all the MAC addresses on the MAC address table, and enter your Laptop's network card MAC address. With MAC Filtering On, do not forget to enter the MAC addresses of all you wireless devices on to its table.
  • Wireless key settings. Disable the wireless key settings and configure it to meet your requirements.

A Laptop to Laptop connection, please make sure the wireless settings on both laptops are the same.

Inconsistent wireless Keys. The key on the laptop has to match the one configured on the router.

Drivers out of date, update your wireless adapter drivers or your router firmware by checking the manufacturer web site.

Wireless not enable on the router. If wireless is not enable on the router, there is no Wi-Fi signal at all. some Router would have wireless turned off by default, and it is the administrator decision to use it or not.

DHCP Server misconfiguration. Make sure the DHCP (Dynamic Hosts Configuration) server is properly configured:

• Enough IP address lease for your network devices
• The server itself is not down

Some simple troubleshooting methods are:

• Repair the connection. On Windows, click start - Control panel and then Network connections; chose the right connection icon, right then select repair. Windows will, temporarily, disable and re-enable your network adapter to attempt a connection.
• Reset the IP stack. Click start then Run. At the command prompt type "command" or cmd for short, you are then presented with the command prompt window. Type "netsh int ip reset resetlog", and then restart your Laptop. This applies to desktop computers as well.
• Reset the router to its factory default. Most routers we use at home are fitted with a reset button, by pressing and hold it for few seconds will bring the router to its factory default. This method solves a lot of the issues mentioned earlier, in one go.

When connected via wireless open a command box and type "ipconfig /all" and note the DNS settings assigned to your laptop. Then do the same with the wired connection. If the wireless connections are not receiving valid DNS settings, that would explain why you won't be able to access any Web sites. You can then re-configure your router to issue the correct DNS settings as per those issued to the wired connection. You could alternatively add these DNS servers as static settings on your laptop, but its best to do it on the router and leave your laptop set to automatic.

Hello friend,
i guess that you are talking about wireless code, in this case you will need to connect the laptop to the router via Ethernet cable to configure it and then unplug the cable and use the wireless.
so you connect the ethernet cable between the laptop and one of the ports on the router from 1 to 4. then access to the router web interface which is usually 192.168.1.1. then go the wireless tab and name your wireless access point and put a password to secure your network. After that you can unplug your Ethernet cable and use the wireless on your laptop to connect your router wirelessly.
Best Regards,

how about to reset your router and setup it the proper address by your internet provider..
laptops only connect to the router automatically if you enable it reconnect and detect its network without manually connect internet, this procedure can see in your wireless properties by enabling it.
And also ask your internet provider if theres a problem also with their internet connection.
Good luck!

If you connect the laptop wired, does it work correctly?
If your Wireless router has password protection, try resetting it to factory defaults, and connect it that way.  If you can connect with the factory defaults (with no security), it's likely an issue with the security on your router.
I'd suggest starting again. Reset to factory defaults, re-secure the network and try a different SSID name this time, and try again.

Run a cat5 cable from the laptop to a cat5 port on the router, open internet explorer in the address window type http://192.168.1.1 or what ever the IP address of the router once you have accessed the router create your PPPOE internet connection, enter your Internet Service Provider's username and password. Once you have done this, disconnect the cat5 cable and connect wirelessly to the router from the laptop. If all this fails press and hold the reset button on the back of the router for 10-15 seconds this will reset the router to factory defaults. connect to the wireless router and create the PPPOE connection.

Try resetting the device to the default factory settings. Then see if you can get an IP address, either wireless or ethernet, to configure the router through its web interface.
