Computer says connected,but wont pull up browser!

Try pinging something like google.com. To do this in windows 7, open the start menu, type "cmd" (without quotes) in the search area, and open the first utility which comes up. This is the command prompt. In the command prompt, type "ping google.com". It will try to send 4 packets to google.com and see if it gets a response. If it says "Request timed out", there is something wrong with your internet or network connection. If it gives you a reply like, "Reply from 74.125.95.103: Bytes=32 time=52ms TTL=53" your network is fine, and there is something wrong with the software on your computer.

Have you tried to power cycle your modem and the router. Your connecting to the router but your getting no connection. Its like getting in your car to go somewhere but theirs no road. Power cycle the modem and router by unplugging it for 30 seconds, totally disconnecting power and plug it back in. Wait a minute and try to connect again with your computer.

(s)he says that other computers work with the router - so it shouldn't be the problem, at least not in general.

Well your computers that have been hooked up can work fine. These things use DHCP addressing and can actually run out of IP addresses to assign if setup wrong, and it never hurts to power cycle them and it takes a minute. If not that then it could possibly be a virus trying to redirect your web page.

ok.. i typed in "cmd" and got back response:

74.125.159.147
bytes: 32
time: 51
ttl: 54

So what does this mean? From above i get there is something wrong with my software... So how would i fix this?!

It means that a packet got through from your computer to google's - which means that your network connection is working.
As to what to do now, honestly, I don't really know.
Two things that I would try are re-installing the web browser (or installing a new one) and checking the computer for malware.

ok thank you! do you have any idea as to how i am suppose to re-install a web browser? im not very smart when it comes to computers.. should i just take it in to like a best buy or something? i dont wanna mess it up anymore than it already is

To install a web browser, go to one of your computers which has internet access working, download firefox (or chrome, I just like firefox better ) and run the installer. For malware, run any anti-virus you may have installed. If you don't have any installed, I'll think about ones which you can install without using a web browser. I know that you can install Spybot S&D (which is free) from a downloaded package, but I'm not sure if you need to download updates or not. It's worth a try at least. The other one which I recommend is Microsoft Security Essentials (also free).

ok.. so how do i get it to the desk top that isnt working? like i said above, the other 2 computers are working just fine.. its just the 1 desk top that suddenly stopped!

Is it that windows won't work, or that just the web browser won't work? If the former, there is a whole different set of things to try. If the latter, I'd just take a USB thumb drive and put the files on it from a computer which can download them. You could also burn them to a CD.

ya i'm not able to pull up anything on the internet... no web page will show up when typed in the search bar. i have tryed taking out usb internet thingy and re-installing and it still will not work!

I found this on another forum and it worked for me:

next flush dns , this will resolve a corrupt dns folder
start>search>type cmd> right click " command " and run as admin .
type cd\ and press enter next at the prompt type ipconfig /flushdns
c:\>ipconfig /flushdns
If you have a copy of HostsXpert , select MS default , if you don't have a copy , then copy across with cd or usb .
And lastly winsock reset , as above from an elevated command prompt cd\ >press enter , from c:\> netsh winsock reset
c:\>netsh winsock reset and then press enter

but i connect my laptop anathar wailess modem.

Where do I go to flush the dns? and then what do i type and where?

My issue with this problem was Norton Internet Security!!!!!!!!!! As soon as the ping showed me that the connection was intact then I uninstalled Norton and voila! The internet was back!   

Ya i don't know much about computers at all.. So i just took it in to get looked at, they charged me $50.00 i guess my computer had a virus on it that wasn't allowing my browser to pull up so the guy tells me! My laptop later took a shit, the hard drive crashed or whatever and he couldn't fix it for a reasonable price! Guess it pays to know something little about them...
