I don't have internet access after I reset my modem?

I bought a new game in steam and when downloading it I realised that the download speed was slower than usual looked up on the internet how to make its speed faster and I read that if you unplug everything from your modem which I did a while ago because I went on holidays and plug everything back in you should reset your modem so I did I tried the download again but I can't access my internet on my computer (windows 7 hp) it says I'm connected to the internet but don't have internet access and I can't access the internet in my computer laptop iphone iPad or anything so does anyone know how I could fix this problem

Does it say your connected to the router with internet access or just connected to the router? You may want to try and reset everything again. Unplug modem and router, disconnect cables etc… Wait 2 minutes then plug modem in. Let it go through its paces before hooking up router. Modem should go through a down link and up link cycle. Then, the down and up lights should come on solid along with a light of the world meaning internet. Thats if you have these leds on the modem. Then plug the router in and see if that fixed it. But otherwise just simply disconnecting the modem and router shouldnt kill your internet.

Then reset everything include setting of modem
