Recently I have been getting wireless connection problems on my 2 month old y580. I was unable to connect to my wireless router. It would try to connect to a network repeatedly for 5 to 6 times and ultimately fail. Recently I found a fix where if I comepletely disable my Windows Firewall it would allow me to connect and I can turn the firewall back on afterwards. My problem however is that i need to do this everytime my computer restarts. I have no problem with doing this because it works just as fine as before but I am sure there is probably a permenant fix to this.

Welcome to the Lenovo Community.
If no third party application (such as Norton, Mcafee, etc. mo) monitors your Firewall settings,
Try to do the following:
1. Reboot into Safe Mode with Networking (to access this option, press F8 during boot-up) and try to connect. If it works, perform a clean boot. and test with the Windows Firewall ON.
2. If Step 1 doesn't work, uninstall the Wireless Network Adapter under Device Manager (click start > type Device Manager) - this will refresh the wifi card's settings to factory default
3. If you have the Wireless Centrino N - 2200 or 2230 under Network Adapter, go to your wifi router & check if you have WMM under QoS - disable this setting if applicable since there's a compatibility between these cards and WMM.
4. Reboot your wifi router (unplug it for a minute and turn it back ON)
If the above steps doesn't work, you will need to create advanced firewall rules to connect to your wifi router.
Hope this helps
