Try a hotspot near home.
Also we have too many posts like this and it turns out to be the old WEP security issue. Let's hope you are broadcasting SSID, using WPA-PSK so we don't run into that old issue.
Tell a little more.
I started my computer yesterday after coming home from work to find that the wireless internet is not working. I know the router is not the issue because I have other devices and computers connected to my router. On the laptop, there is a switch on the front for wireless with an LED indicator light, red when it's off and blue when its on. no matter which position the switch is in, the light is always red. One interesting part is that the wired networking is still working fine. I tried going onto the HP support website and downloading a new driver but I either got the wrong one or it did not work.
does anyone have any idea what could be wrong? the last time this happened it was a full system failure and not just the networking, so i'm hoping there can be an easy fix in order.
