I usually have my G580 laptop hardwired to my router, so I wasn't checking wireless connectivity on a regular basis. But it won't connect anymore (it used to work).
Everything else I own workes fine over wi-fi on my Netgear router (Android tablet and smartphone, HP Windows Vista laptop, etc.).
I took my G580 laptop to McDonald's this morning and it connects to their wi-fi easily.
Solved! Go to Solution.

Just to verify, when you connect to the Netgear accesspoint, are you getting one of the errors below?
Things that you can try:
1. Reboot the router
2. Remove the Wi-Fi network and try connecting again.
If you have Win7, navigate to Control Panel (icon views) > Network and Sharing Center > Manage Wireless Networks and delete the Netgear accesspoint.
If you have Win8, right click on the Wi-Fi network and choose Forget Network
3. Uninstall the Wi-Fi Adapter by navigating to Device Manager Network Adapters. When finished, scan for hardware changes and reconnect to the wireless accesspoint then observe.
Let me know how it goes.

Thanks for your reply. I've already tried your items 1) and 2), which doesn't fix the problem. Your step 3) I am a bit leery of trying....it I uninstall the network adaptor, will I be able to restore it? Also, there are 4 devices listed:
Anchorfree HSS VPN Adaptor
Anchorfree HSS VPN Adaptor #2
Broadcom 802.11n Network Adaptor
Qualcomm Atheros AR812/8166/8168 PCI-E Fast Ethernet Controller (NDIS 6.30)
I know what 1 and 2 are, which one do I uninstall 3 or 4? When I "Scan for Hardware Changes", will they be restored?
I am baffled why the Lenovo connects at McDonald's, but not at home. What's Ronald got that I don't have?
Thanks for your help.

Oh yeah, one more thing, the Lenovo supposedly connected, but it says "Limited" on the connected logo. But I can't get anything over the internet.

If you uninstall the Wi-Fi adapter (Broadcom 802.11n Network Adaptor), don't check the delete the driver software for this device so that it will reinstall the driver after you do a scan for hardware changes.
As for getting a "Limited" connectivity, do you have a valid IP address (eg. 192.168.xx.xx) when you get this network status?
If you get a valid IP address (192.xxx.xxx.xxx / 172.xxx.xxx.xxx / 10.xxx.xxx.xxx) then there's most likely a security software that's interfering with the internet connectivity. Try to uninstall any security software on the machine (eg. Mcafee, Norton, AVG, etc.) and observe.
If you get a 169.254.xxx.xxx IP address then you're most likely getting a DHCP failover (APIPA). In this case, open a command prompt as admin and type the following commands (reboot if necessary) to refresh the winsock and TCP/IP configurations:
netsh winsock reset
netsh int ip reset

I tried your admin command prompt suggestion first. It didn't fix the problem, I still can't connect via wi-fi to my router. I started to uninstall the Broadcom 802.11n Network Adapter per your suggestion. When I click on uninstall I get the warning prompt, but there is no checkbox for not deleting the driver.
I don't want to proceed with this uninstall for fear I will lose this driver. Any suggestions?
Thanks for your help.

If you look under the Broadcom 802.11n Network Adapter (Properties) > Driver Tab, what does it say on the Driver Provider?
If it says Microsoft and not Broadcom, can you try the following:
- right click on the Broadcom 802.11n Network Adapter and choose
> Update Driver Software
> Browse my computer for driver software
> Let me pick from a list of device drivers on my computer
- on the list of drivers, select the driver that has a (Broadcom) and try connecting again to the Wi-Fi network.

Hi neaokenchi -
I think your last post solved the problem. I did not, however, install a new Broadcom driver. The Broadcom driver source was Broadcom, not Microsoft. I right clicked on this listing under Device Manager - Network Adapters. There was a button for "update driver," which I did. Searching the c: drive, I found two Broadcom drivers - one whose source was Broadcom, the other Microsoft. I picked the Broadcom one and updated it.
I then connected to my Netgear router sucessfully. Hooray! 'hopefully it continues to work.
Thanks SO MUCH for all your thoughts and suggestions. I really appreciate it!

Hi - I guess I'm not out of the woods yet. It seems like after about 15 minutes of wireless connectivity on battery, the connection shuts off. I have to turn off wi-fi, then turn it on again. It then reconnects for the same amount of time.
