no wireless networks were found in range ???

Hi guys , here's the story and thanks in advance for your time to read this :

I came back home from school today , i started the laptop , then suddently , during boot , i think it restarted itself. Then , i tried to press power again , i get a beep from the laptop , saying my laptop was warmer than expected. But i never booted the comp before?? My room was normal temperature as well. Then it says Strike F1 to continue , then i continue. When i was in deskptop , usually , it automatically detects my wireless router (A D-link Dl-624 Airxpress something) but today , it din't connect !!! Im 120% sure that the switch is on , i haven't touched anything , impossible that i disabled something in the bios. My router seems to be working , my only wireless connection is the laptop , and i have 2 other deskptop which are connected via cables , they're both going fast & smooth except for my laptop ... which keeps saying no network in range =( , not even neightbore hoods....

Should i call up dell? I have complete care package. Thanks.

 

Try to reset your wireless router, most have a small pinhole on back, side or bottom....may have to use a paperclip (unfolded) to hit the button. Once the router is back up, go ahead and restart PC. If networks are still not found...look on your router for a I.P. address, (most are something like 192.168.0.1) Then open your browser (internet explorer/firefox/etc) and put that I.P. address from the router into your browser search box....If it's not found then call your support. Hope this helps

 

Don't bother messing with the router just yet. It sounds like you have laptop issues. Call Dell.

 

yes dont worry..
