Limited or no connectivity

Error: Limited or No connectivity.

You get this error generally on Windows XP computer while connecting to the wireless network.
There are possible 2 reasons for this error message.

First, the wireless network key that you have entered is not correct. You may need to check the wireless settings of the router.
Open the setup page of the router and check the wireless settings. Make sure that you have the correct wireless network password. If your router is using WEP security mode then network key will be 10 or 26 digit hexa-decimal number and not the passphrase. The password is case sensitive.
How to check wireless network key:

Second reason, your computer is not getting IP address from the router. Make sure that DHCP server on your router is enabled and it is assigning IP addresses to all the computer. If other wireless computers are working and only one computer is getting error "Limited or no connectivity " then you can try assigning a static IP address to the computer.

You can also try to remove the wireless network profile from the computer and manually create a new profile.
If you have only one wireless computer in the network and if it is getting the error "Limited or no connectivity" then I will suggest you to create a new wireless network. Lower down the security level and see if that works. Open the setup page of the router. Change the wireless network name. Change the wireless channel and change the security key.
Also make sure that Wireless MAC filter is disabled.

Settings saved on this computer do not match

Error : "Settings saved on this computer do not match the requirements...."

What does this mean and why am I getting this error when I try to connect to the wireless network.

You get this error when there is a wireless network profile is already existing on your computer. This is the error on windows Vista and Windows 7 computer.

There may be many reasons behind this error.

Let's take an example. 

You have a Linksys router at home and you are getting wireless network through this router. The name of your wireless network (SSID) is "Home" and there is a password on the network. Let's consider the password on your network is ABCDEFGH . Your wireless network profile is already saved on your computer with the SSID Home and password ABCDEFGH.

Now you go to your friends place. He has a Netgear router at home. And the wireless network name (SSID) of his router is also "Home". But the password for his network is IJKLMNOP. 

You go to your friend's place and try to connect to the "Home" network. But the password saved on your computer for the "Home" network is different than your friend's network.

Now you will get the error " Settings saved on this computer do not match the requirements..."

How to get rid of the error message "Settings saved on this computer do not match the requirements..."?

It is really very simple.

First you will need to delete the wireless network profile on your computer.

Open Network and Sharing center.

Click on Manage Wireless Networks in the left panel.

You will see your Network name in the list.

Select your network from the list and click Remove.

Now try to connect to the wireless network again.

This time it will ask you for the network key. Enter the wireless network key and you are done.

How to change NAT type to open

Easy steps to change NAT type to open :

Let's understand what is NAT?

NAT - Network Address Translation - It is a networking concept used by network router to share one public IP address among multiple private addresses.

Let's consider you have 4 computers in the network. Each computer requies IP address in order to communicate with other computer and get Internet access.
You have Internet service provider and your service provider has given you one Internet modem. Now this Internet modem will assign only one public IP address. You can connect only one computer to the modem and get public IP address to get on the Internet.
Now if you connect modem to the router, then modem will assign IP address to the router. You can connect all the 4 computers to the router. Router will assign it's own private IP address to all the computers in order to communicate with them. In this way only one public IP address is used and 4 private IP addresses to get all the 4 computers on the Internet.
This is the basic function of all the routers.

In case of gaming devices they need to communicate with the public IP address. If you have connected router behind router then you will get strict NAT issue.
Some DSL Internet service provider's modem acts as a router. You connect your router to that router. In this case there are 2 routers in the network.

There are 3 types of NAT issues with the gaming devices.

Open NAT: This means the settings on the router are good and you are able to play the online games.
Moderate NAT: In this case you can talk to other players online who have open or moderate NAT.
Strict NAT: In this case you can not talk to the players who have moderate or strict NAT.

How to change NAT type to open?

In order to change NAT type to open, you will need to make some changes in router settings.
Change the MTU settings to 1365.
You will also need to open some ports on the router. The ports numbers are different for different gaming stations.
Disable firewall on the router. Do not disable SPI firewall.
If you are using DSL Internet service then make sure that your modem is in bridge or PPPoE mode.

192.168.1.1 how to setup

How to setup Linksys router using 192.168.1.1 ?

192.168.1.1 is the default IP address of almost all the models of Linksys router.

If you type this number in the address bar of your Internet browser, it will open the setup page of the Linksys router.

Your computer must be connected to the router in order to open the setup page.

I will recommend you to connect your computer with the Ethernet cable to the Linksys router. Do not use wireless computer to open the settings page, even if it is connected to the wireless network.

Connect the computer to one of the Ethernet ports on the router. If you connect the computer to the Internet port then your computer will get auto-configuration IP address like 169.254.1.x and this IP address will not communicate with the router. So the connection to the router is very important. 

Check the IP address on your computer.

Open the command prompt and check the IP address of your computer. In the command prompt type "ipconfig" and hit enter. You will see the IP address and the default gateway number. Default gateway number id the IP address of your router.

In some cases you will see only IP address and no default gateway number. Make sure that your computer is not using static settings. Go to Network connection. Check the Local area connection properties. Make sure that there is no static settings or bridge connection.

The default IP address of WCG200 is 192.168.0.1. WCG200 is a cable modem + router. This is the only cable gateway that Linksys has.

If you are not able to open the setup page using 192.168.1.1 then try to ping that number. In the command prompt type " ping 192.168.1.1 "  , hit enter. If you get 4 replies than your computer is communicating with the Linksys router. Make sure that there is no firewall on your computer. 

If you have DSL Internet connection then I will suggest you to disconnect the Internet modem from the router. Connect only the computer to the router. Reset the router and then try to open the setup page using 192.168.1.1.

If you are still not able to open the setup page then try How to open setup page of the router.

If you reset the router, you will lose all the settings on the router and you will need to reconfigure it from the start.

How to find wireless network key

Easy steps to find the WEP, WPA or WPA2 password:

What is WEP, WPA, WPA2 key?

WEP, WPA and WPA2 is nothing but the encryption key of your wireless network.
In order to connect to the wifi, you need to enter the password. In other words your network is secured and you are not allowed to get in without the security password.

You might have installed the router a long time back. And now you don't recall the security key. You have not written it anywhere. You might have it written somewhere but now you don't know where it is?

Trust me these are very common issues. I used to take calls of many customers who were looking for the security key.

It is not difficult to find the password.

You need to open the setup page of the wireless router that you have. Setup page is the page where you will find all the settings of your network. The default IP address of most of the Linksys routers is 192.168.1.1. The default password is admin.

If the default log in is not working then you can try some of your common details. if nothing is working then you may need to reset the router to factory default.
Remember, once you reset the router, it will come back to factory default and you will need to reconfigure it from the start.

If your router is using WEP security settings then network key will be 10 or 24 digit hexa-decimal number.

Once you open the setup page, go to wireless settings and look for the password.

If you are using Linksys E-series or EA-series routers then you can find the password on the Cisco connect software also.
Open the Cisco connect software. Go to router settings. You will see the router user name and password. This will be the security key of your wifi.
