Windows 7: Laptop wont connect to the internet

Hey guys I have an Acer laptop windows 7, but Just recently (yesterday) a problem came up that at first I thought it was the modem but now I see the problem is my laptop. and basically when I run the windows network Diagnostics 3 problems come up: 1. None of the networks you have previously connected to are in range, 2. problem with wireless adapter or access point, and 3. the default gateway is not available.



So I am not sure what to do, any help is greatly welcomed. Thanks

Unplug the router, wait five minutes, plug it back in. See if you can get to the device webpage, 192.168.0.1 or 192.168.1.1

but its not just from my house, I cant get internet anywhere not even in school =/ it says "limited access" or "no internet access"

Is your wifi disabled in network and sharing center, change adapter settings?

its enabled but it just says "unidentified network"

Try a recovery to a few days ago before the problem started, if you don't have recovery dates available, you should check to see if you have a virus using Malwarebytes.

I did try a system restore but nothing happened so I dont think its a virus

Can you connect to the internet using an ethernet cable?

not even, I tried it yesterday and it just says the same problem, like it shows full signal in the wifi but then it has the little yellow warning triangle that either says "no internet access, or limited internet access"

I can only guess that your anti virus is blocking you or you have malware on your computer that is redirecting your network connections...check the IPV4 settings of your adapter to make sure you are set to auto connect. Run Malwarebytes. Check device manager to see if there are changes to your hardware. Open a cmd window, type ipconfig /all, save as a txt file and post it here as an attachment.
