I'm connected to router bit says no Internet access?

My acer laptop says it is connected to my network but that there's no Internet access. All my other devices on the network are working fine though (Mac, iPad, and iPhone). How can I fix this problem? Thanks!

Added (1). I mean that my Mac computer, iPad and iPhones are all getting on the Internet just fine but on the acer laptop it says there's no Internet connection, but it is connected to the router fine, sorry I'm just not very good with computers lol. Also it was working fine last night and I was on the Internet before I went to bed, but no Internet this morning

Check the routers configuration to see if there's any rules in place preventing it; like MAC filtering.
Or try rebooting it, that usually does the trick for me.

Windows?
You could also try IPCONFIG command to renew the IP etc - http://www.ehow.com/...onfig.html

What's the ip address of your router the default gateway what do you mean other devices with run - cmd type ipconfig that will tell you.

What your saying does not make sense do you mean the other devices are on the network but with no internet access?

This is a domain at work? Being cagey with your info is not going to help

Call your isp

  • What is the difference between 32 bit and 64 bit in the iPhone 5S? I was wondering what is 64 bit and why does it matter on an iPhone? What makes it different than the iPhone 5 or any other smartphone right now, and should we really care?
  • What does it mean when your internet says connected with limited access? I have a windows vista that's 2008. My house internet went down yesterday so I had to take the plug out of the internet and plug it back in after 10 minutes. Then everything worked but today my laptop says connected with limited access but my iPad internet and iPhone works fine. So what to do? I tried everything on google but it didn't work. My sister said its like something I downloaded but I didn't download anything since like 2 weeks. So what to do?
  • Router only allows 1 device Internet access? I have a linksys router. Has worked fine for a while. Just got Internet back. Whatever device connects wirelessly to it first works perfectly fine. The next devices that attempt to connect to it get assigned the generic 192.168.1.1 ip and do not have access to the Internet. I have no computer, using iPhone and iPad to set this up. Dchp is on. I've reset it several times and tried. Changed the ip of the router, etc. I'm sorta technology illiterate, and need some help./
