Windows declares it has excellent signal strength but can only give limited connectivity (no internet). Open WiFi. How to make it connect?

IMHO, the problems lies with the laptop's IP setting. If your router is set to OPEN, means anyone can tap on and connect with key-in a password, but your laptop still get "limited connectivity" issue, you may have to check your IP setting in: XP : control panel > network connection > select your WiFi connection, right click on it and select "Properties, double click "Internet protocol (TCP/IP), check the IP setting. Select the "obtain an IP address automatically", your router must also enable DHCP to allow the IP to be automatically configure.

If you select "use the following IP", you can input your own IP and still be able to log in by input the correct IP. Most router's default setting are 192.168.1. XX or 192.168.0. XX, where XX is a number from 0 to 255.

Router mostly occupied 0 or 1, you just type any number (e.g. 100). So your setting may be: IP : 192.168.1.100 Subnet mask : 255.255.255.0 Gateway : 192.168.1.1 or IP : 192.168.0.100 Subnet mask : 255.255.255.0 Gateway : 192.168.0.1 Retry the Wifi and see if it connect. Good Luck.

It's very possible that the problem could lie within the router. Have you tried to plug in a different router instead, to test it on that network? I have had a similar problem before, and it turned out to be a problem with the wireless router.

Unfortunately the only solution was to replace it. That may not be the problem with yours, as other's are able to connect to it, (is it at the same time? ) Have you tried downloading the newest wireless driver for your laptop?

Or You could try an ipconfig Start --> Run type cmd and click 'ok' then Type: ipconfig /all.

The vast majority of times I have seen wireless go "wonky", there has always been one good first solution: reboot the router. Please note that this is not a guaranteed fix, but a good first step that will resolve most "bad states" that can occur with a modem/wireless router.

What you need to do is unplug it from the wall. Wait for about 30 seconds. Then plug it back into the wall.

You may also want to reboot the modem (I am assuming cable or DSL), too. If you are rebooting the modem, I recommend doing it with the router. Unplug both devices.

Wait about 30 seconds. Plug the modem into the wall. Wait for the appropriate lights to come on as described by your manual.

Plug the router back into the wall. After the router comes all the way back to life, about 20 to 60 seconds, then your computer should automatically reconnect. If it does not, do a search for the network and attempt to connect.

Typically, things like spikes, brownouts, and blackouts cause routers to get into a bad state that prevents connections or internet access.

I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
