Wi fi adapter all of the suddenly cant connect


There are several possibilities, but without some details I can only guess what's going on. I'm going to assume the problem is on a home network and you're using a current version of Windows in hopes of sending you some quick help, but if those are bad assumptions, please send details.

You can run Windows wireless diagnostics by clicking on the icon that looks like cell phone bars at the lower right hand corner of your screen. Next choose Open Network and Sharing Center, then Troubleshoot problems. That process may solve the problem or it may make a suggestion on your next step.

You might turn off your cable or DSL modem, and then turn it on again.

If you're using a laptop, you might check to see whether there's a wireless radio switch that has been accidentally turned off.

You might restart your PC.


I'm guessing that you know the WiFi hotspot you're connecting to hasn't changed its security settings or name. However, if someone else manages the WiFi network you're connecting to, ask that person if they've made changes.

These should address the most likely culprits. If not, please send info about your computer, your network, whether you can access the Internet outside of your web browser (e.g. can you get email in Outlook), and what you've tried so far.

A wonky PC is the pits. Best wishes on quickly getting it going again.

Dell Latitude D 410 has suddenly (worked yesterday) stopped connecting to all known (and working) wireless networks. Is my internal wireless card gone?


If you get a 'Limited connectivity" on you wirelessconnection on your laptop, it means that the wireless card on your laptopprobably did not get an IP address from the wireless router.
To fix this problem, right click on the wireless icon on the Task bar and thenclick Repair.
This will force the wireless router to issue a IP address to the wireless cardon the laptop.

Windows cannot connect to the wireless network


I would remove old cache wireless network connections. Example is when you once connect to a free wireless access at Library or Coffee Shop. Windows save all of these profiles and this will cause problems connecting. Then use Microsoft Wireless Troubleshooting resource:

Good luck

Wireless Router suddenly stopped working.


Try resetting the Linksys back to the factory defaults and configure it again.
Power up the router and press the pinhole RESET button on the back of the router for 30 sec
Connect a LAN cable to the wireless router and open a browser and enter to router's configuration IP address and configure the wireless settings, remove the LAN cable when configuration is completed.
You need to configure then wireless card in the computer/laptop with the router's wireless settings.

No wireless networks found in range


Are all the LEDs on the wireless router are on?
When you reset the wireless router wait at least 1/2 min before powering the router up.
Right click on the wireless connection and click on Repair, this will force the wireless router to issue a new IP address to the wireless card. If the the red x is still on the wireless conection then :-
To check if the wireless card can communicate with the wireless router, ping the IP address of the wireless router, (this is the IP address that is used to login and configure the wireless router) if you get no reply and all packets are lost, then connect a network cable from the laptop's RJ45 port to the wireless router's RJ45 port and do the ping test again.
If you still get no reply and lost packets then most likely you have a faulty wireless router.
Get back to me on the results of the tests and I can then advise what to do next.

you could download the drivers and reinstall them and if spyware doctor and win defender are registered you can always retrieve them.
