Wireless network not validating - when did eric and calleigh start dating

The router is an AT&T 7550 Router and the Laptop is a Dell Inspirion. If you find your wireless connection icon in grey color then right-click on it and select "Enable". I suddenly realised dt it's not bn connecting to the internet, I took it to my place of work to confirm if there's problem with my home wifi. I rang the seller to let them aware, as it is under 28days. I rang Toshiba and they said to me they have no warranty on it. Had others tell me I needed to DL various programs to detect the problem, which I didn't want to do.

To help verify this is not the problem, disconnect the power from the back of the modem and router.

Hello, I have a Dell laptop that will not connect to the wireless Internet provided by my in-home router.

I can pick up wireless from my i Pad and three different i Phones, but not my laptop.

In the Network Connections window, if your wireless connection is listed, right-click on the connection and select "Enable." If you see "Disable", the network connection is already enabled.

If your wireless network shows multiple available wireless networks, make sure you are connecting to the right SSID (router name) and that you have entered the correct security key.

If the box was checked, then that was why you were getting the “unable to find a certificate to log you on to the network” message because Windows is looking for one, but your wireless router is not setup for certificate security. Once I unchecked that box and tried to reconnect to the wireless network, everything worked fine!

There are several things that can cause a Wi-Fi connection to stop working and steps that you can do to fix the problem.

Once disconnected, wait 10-15 seconds and then reconnect the power.

Wait several minutes for the modem and router to reconnect to the Internet, then test the Internet connection on your computer.

I can access internet on the laptop when plugged into the router's ethernet cord, but not through wireless.

It shows me my network when I try to logon, but it is grey in color and unable to select the wireless network. In search box, type and press Enter "Network Connections" window will be opened. I just bought the new Toshiba laptop and only used it once after the installation. I've had this problem for 8mths now and couldn't figure out what happened because I was using it when it suddenly went dead. basically on windows 8, I uninstalled the wireless adapter in the device manger and then chose 'scan for hardware changes' by right clicking on network adapters..

If you are connecting to a neighbor's router or are entering the wrong security key, the laptop will not be able to connect to the network.
