I am unable to connect internet on samsung r580 windows 7 on my pc win 7 it works fine but it wont works on r580

Not being able to connect to the Internet depending on what method you are using for your internet connection if wireless or cable or DSL I would reboot everything unplug it all modem routers if any and modem or DSL box and the computer as well. What happens sometimes when Windows sleeps it closes off the Internet connection as well and you may have to log back in. Make sure that you are powered off and then connect everything back up again and let it do its thing and try to access the Internet again.

If it will not access the internet make sure that you do not have laptop set to wireless if you are using a cable or DSL R-45 cable wiring. I'm assuming wireless for the laptop so make sure that the switch if any is switched to wireless as well.

If all else fails contact your IP service and have a technician come out and take a peak at it. Often times it has been my IP on their end that does not work and they have to reset the router or modem to get the DNS to work again. Often times it is just easier to call them and have someone come out and fix it should be free for you to have this done. Thanks for using FixYa! I hope this assisted you. John
