wireless not detecting any connections

[AdverseDeviant]

i have a hp g71-340us laptop and i pushed the wireless switch to turn my wireless back on to use it and the light turned blue but windows still has a red X and no wireless connections available showing. Ive tried disabling/enabling, safe mode, restart of wlan services, reinstall of drivers, turning it back off and on, and googling sire after site. The wireless was working just fine ealier today. I tried connecting my computer to my school's lan from ethernet but the computer just says unidentified network. I dont see why the ethernet shouldnt work because i basically disconnected the cable from one of the pcs in the lab at school and plugged it into my computer. Ive also tried different parts of campus to try to use different routers and also tried deleting the profile. Any suggestions?

You have a software firewall (not Windows Firewall) installed? Try disabling that as well as do a full malware scan to see if that catches anything.

If it's not a software firewall, sometimes you just have to be patient and wait for it to pick up the signal. As ridiculous as that sounds!!

I've gone through those changes of disabling/enabling, etc., several times here and found that just by waiting a few, it finds the connection.

There are plenty of reasons why this sort of thing wouldn't work -- most companies and schools don't allow unregistered devices to just plug into their network. Quite possible a school would be running NAC or NAP

Simple form of this would be to setup dhcp server to only serve IPs to know mac's -- so if your computer interface is not registered with the network admins it would never get an IP. There many many ways to keep unknown devices from just plugging into a network and getting access.

As to not seeing any wireless network, like mentioned give it a few minutes sometimes. Also maybe their is no wireless network broadcasting SSID, so you wouldn't see anything. Possible your not in range of any wireless, possible it only B and your set to only see G or N, again there are plenty of reasons why you might not see any wireless networks. Could be your wireless card just died, just because it worked before does not mean its not dead now.

I wouldnt expect your laptop to work on the school network, that would be just be stupidly insecure, likely mac filtering. As above it likely dead if you have done all you said you have, they are only cheap, replace it.
