Hey everyone.
So just recently i cancelled at&t internet and switched to Charter and connects through cable.
but anyways after installation the technician used my laptop to install the internet.
So internet works and is fast but once i turn off my computer and i turn it back on internet won't work anymore. I keep getting a DNS error kind of thing. There are 3 other computers in my house and they all work fine even my phone connects to my internet fine just my laptop.
So i looked online and tried stuff but nothing seems to work.
Finally I decided to just factory image restore my laptop. After the process it works fine!
but then once i shut off the computer and turn it back on it fails again.. DNS error... or something.
Please helpp!! :confused:
Thanks
 
"DNS error...or something" doesn't really help us. We need some specific error messages in order to help you.
 
Sorry about that.
Well this was what i got using google chrome.
"error 105: Unable to resolve the server's DNS address"
also none of the other browsers i used works.. IE, Mozilla.
OH and also my laptop is a Dell Inspiron 1720 running Windows Vista Home Premium.
Thanks
