Are you able to access the internet but just not surf? For example, can a program of yours that would have an update feature use that feature to download an update from the internet? If this is the case, go to your browser and change your LAN network settings to "No Proxy" detection. Apply and restart browser. Also, make sure the DNS entries are the same for your device as are on the router, but most likely you are using auto detect. Is this router you are using a router controlled by you? If it is a public wifi network, they may have certain settings you need before you can surf the internet on their network. What utility are you using to connect to the wifi, is it the windows default or are you using an Acer program sent with the laptop?

I would suspect a firewall is blocking as you can ping google all OK
this IP 209.191.93.53 also times out for me - so i suspect and issue on the internet - anyway the fact you can ping google.com proves you connected to the internet

What firewalls have you on the PC, Norton, Mcafee etc ? - Turn them off - or disable and see if you can now connect
