Problem connecting 3rd computer to internet

Hello, I have been having a very persistent/annoying problem whilst trying to connect my fourth system through my wireless router. As of now, I have an HP and an Xbox360 hooked up via ethernet cable and a seperate computer hooked up wirelessly. All of these work fine. The problem with the last computer started about a month ago.. I suddenly started getting "Limited or no Connectivity" bubble at the bottom of the screen. In the beginning, I could fix this by turning the router off then back on, but that does not work anymore. First off, my computer (2.8 GHZ Sony VAIO) is able to find the network at 54m's and with excellent strength. When trying to connect, it will say "network connected," and then then will be stuck on "aqcuiring network address" for like five minutes, then switching back to the "Limited or No Connectivity," which as such I have absolutley no access to the internet. I have tried every possible related solution on this site but nothing seems to work. I have rebooted, reinstalled, and rerouted all my modem and router, but that shouldnt even be a problem seeing all of the other computers work. I also tried anything associated with an IP address conflict. My default IP is set at All of the other systems on the network use I have gone into the properties tab and manually configured the IP address as well. It is strange when I do this, however, because after manually configuring an IP it will say "Wirless Network Connected" at the bottom of the screen, appearing to be fixed , but I still have absolutley no access to the internet. I'll share some of the wierd symptoms it's been having:

With IP address set to auto configuration, computer remains with "Limited or No Connectivity" for about 7/8ths of the time. Occasionally there will be a hiccup where it will load half of the Yahoo! home page, and stop.

When configuring my IP address manually, everything appears to connect almost instantly, but still no access to the internet.

I have tried running an ethernet cable to the computer as well. It informs me that my LAN is connected, but I still recieve "page cannot be displayed" in the internet browser. I do not know if there is a step in activating this that I skipped, but the computer used to run via ethernet before I got the wireless about a year ago.

I have been to the router website, changed my SSID, disabled security, and everything else there that could be a problem.. didn't seem to work... It would take forever to list all of the different solutions I have tried, but seemingly all of the easy "quickfix" solutions do not work. One thing that I need to point out, however, is that when I attempt to type in any of the ipconfig commands into my Run box, I recieve errors on all attempts saying "the command could not be found... please make sure the name is right bla bla bla" (something like that) I don't know if this is significant or not, so whatever.

I honestly am at the end of my rope here. This is hands down the most frustrating network problem I have ever had.

Re: Problem connecting 3rd computer to internet

Would you consider an environmental or systemic reason.

Environmental -- there are many more wireless devices out there including a class that broadcast on two wireless channels simultaneously. You may be having contention for the radio bandwidth not just from other routers but devices like wireless phones. Consider changing you channel from the probable default of 6 to 1 or 11. If the first change does not work try the second. (also keep your wireless router/access point away from the cell phone4.gif base station.)

Systemic -- There is a belief that networks with hidden SSIDs and WEP or WPA encryption experience interruptions some of considerable duration of service manifesting as disconnections registered by the computer's1.gif wireless adapter. Unhiding the SSID has cured these systems.

I hope this helps.

How to configure 4 Lan + 1 Printer +internet connections


If all your connections are wired, you can use one of the three following solutions.

1. Purchase a router with more then 4 LAN ports on it.
2. If the printer or any of the computers have a wireless network card, then purchase a wireless router and simply connect 4 LAN cables and 1 WLAN.
3. Purchase a hub. Connect 3 computers to the first 3 LAN ports on the router; connect the hub to the fourth LAN port and then connect the last computer and the printer to the hub. In essence both your computer and the printer will share the same IP address (the IP given to the hub) and they should work.

In any of these situations, connect the internet connection to the WAN port of your router.

Wireless internet connection issues

Verify you have the correct WEP key, if its wrong it will look like it's connected but not do anything, you could aslo try to connect via a cable into your router to confirm it works, if it does then you have a WEP key issue, if it doesnt then you need to dig a little deeper.

Issue with router and ethernet cables

I imagine you reset/unplugged all of your routers, switches, and computers, starting with your modem, then router, and then each system?

There is a setup disk that need to be used to program your router with the ISP settings, passwords, and protocols for port forwarding, etc. I imagine you tried that.

Did you try all of your cables to make sure they weren't defective?

If you tried these,and the problem persists, the issue is a defective router. By default, the unit should transmit a wireless signal, and be ready to act as a routing switch for your other systems.

Losing internet connection when enabling ICS on the wireless network connection

Do not enable ICS on any of the computers that are connected to a router regardless if it's wired or wireless, you only need to enable ICS is if you don't have a router/server on your network(the purpose of a router is to share a single internet connection from your ISP). To connect your computer wirelessly to the router(on a Windows XP computer given that you do not have a 3rd party Wi-fi application installed) is to right click on wireless network connection on the System Tray(lower right hand side of the computer's Desktop near where the clock is) or you can do it the hard way by going to Control Panel then Network Connections and choose view available wireless network and under the list of available network that your computer can detect, select the network name(also called SSID) of your wireless router and try to connect(of course if you enabled Wi-fi security you also need to key-in the security key(WEP/WPA) you configured on your router and that's it both wired and wireless computer/devices connected to the router should work at the same time.
