"Limited or No connectivity" Problem Fixed, New Problem.

Hello, ok so the other night I was on my 2nd computer which uses a wireless linksys lan card, that connects to my main computer with a linksys wireless b router. For some reason i right clicked on my wireless connection icon which is in the right hand lower corner of my screen, right next to the sound icon. I right clicked and hit repair, it started to say, disabling , then for some reason i hit disable. Anyways after that i started to get the "Limited or No connectivity" problem. So I went and looked for a solution, i came across this site and a person by the name of Sven posted this

1. Click Start, click Run, type "ncpa.cpl" (without the quotation marks) and press Enter.

2. Right-click the connection with an overlaid yellow symbol and click Properties.

3. Click on the "General" tab, highlight "Internet Protocol (TCP/IP) ", and click Properties.

4. Click on the "Alternative Configuration" tab, select the "User configured" radio box.

5. Type 192.168.0.2 in the "IP Address" field.

6. Type 255.255.255.0 in the "Subnet mask" field.

7. Click OK twice.

After following the advice, every thing worked just fine on my system "


I tried that and fixed my problem. My wireless connection was up and said it had a good connection etc. So that was fixed, but now when i open internet explorer i get this error:

"Cannot find server "

The page cannot be displayed
The page you are looking for is currently unavailable. The Web site might be experiencing technical difficulties, or you may need to adjust your browser settings.

Yes i know, this is a typical error, i usually get it when i type an incorrect website address or if the sites server is actually down. But you see i tried many of the popular sites like yahoo, msn, cnet etc. So by now i knew that I couldnt reach any site. Im guessin something is not right in my connections settings. So if anybody could help me with this problem it would be great. Thank you for your time.

Well, a common mistake in wireless troubleshooting is confusing signal strenght with connectivity. You can have 100% of the former and still no connection to the Internet. The problem applies to wired connections. Just stick to the routine troubleshooting steps as if it were a wired network.

1st of all, why do you need to mess around with the alternative configuration for the wireless card? Simply use the primary IP config to its default to obtain IP automatically. The alternative setting is designed for times when you have a static IP at one location and either another static IP or dynamic IP at another location. If not, just set everything at auto IP and forget about it and let the DHCP server on the router do all the IP assigning.

You can have both wired and wireless connection at the same time. Windows will pick the best connection for its Net access.

 

I find that 75% of network connectivity problems i have seen with my job are cured by setting static IPs in the TCP/IP section on every PC on the network. Not in the "alternative" config section though.

If your network is large (over 30 PCs) you may want to look into DHCP servers though.

I am so not a fan of letting windows set its own IP on a network. It is so unreliable and often wont work. Either set a static IP or have a DHCP server running. Note many DSL routers will do DHCP serving for you if told to.

In the case of your internet connection, things to watch out for are gateway IP address, which should be set to either your DSL router's IP (if any) or the IP of the PC that shares its internet connection with the network.

In many cases, it helps to set the Primary and Secondary IP addresses to your ISPs Primary and secondary IP addresses. you can get these settings from your ISP, usually on thier web page. If your DSL router is the gateway for the network, you can simply put its ip in the primary DNS server setting and leave the secondary one blank. In that case your gateway and primary DNS server address IPs would be the same number.

Note: in the case of a PC sharing its internet con with a network, that particular PC shoudl have nothing in its gateway IP setting and nothing in the DNS server settings, only the OTHER PCs need these settings. It should still have a static Ip (usually 192.168.0.1) and a subnet mask of 255.255.255.0
