Solved: Internet is connected, but browser doesn't load
Maybe someone here can help me, because I'm stumped at this.

My laptop is recieving an wired internet connection, but none of my programs seem to be connecting to the signal. For example, Internet Explorer isn't loading pages (just blank), things aren't updating, and my "Weather App" says "Service not available." When I open Safari, it can't open the page and says "The error is: 'There was a problem communicating with the web proxy server (HTTP).' (CFURLErrorDomain: 306)"

The problem isn't in the router, because the desktop I'm using to post this is working fine. The problem isn't in the ethernet cable, because I tried using it to connect the desktop and it still worked fine.

Network and Sharing Center confirms that This Computer is connected to the Network connected to the Internet. When I "Diagnose and repair," the message comes up "Widnows did not find any problems with your internet connection."

I've tried disabling the connection, restarting, and enabling again, to no effect. I haven't tried restarting in Safe Mode yet, because I'm not sure how.

The problem is on my Dell laptop with Windows Vista. We get internet from Comcast, connected to my computer through a Scientific Atlanta modem and one each Cisco and Linksys routers. Again, though, my mystery is that the computer says it's recieving a connection, but it's somehow not being used by any programs.

Hi>Welcome to TSG.
Let's see this from the failing laptop.
Will hopefully tell us a lot about the environment.And we can go from there.
From a Johnwill post on the Networking Forum


Try these simple tests.

Hold the Windows key and press R, then type CMD (COMMAND for W98/WME) to open a command prompt:

In the command prompt window that opens, type type the following commands one at a time, followed by the Enter key:

NOTE: For the items below surrounded with < >, see comments below for the actual information content, they are value substitutions from the previous IPCONFIG command output! Do NOT type <computer_IP_address> into the command, that won't work. Also, the < and > in the text is to identify the parameters, they are also NOT used in the actual commands.

Do NOT include the <> either, they're just to identify the values for substitution.

IPCONFIG /ALL

PING <computer_IP_address>

PING <default_gateway_address>

PING <dns_servers>

PING 74.125.45.100

PING yahoo.com

Right click in the command window and choose Select All, then hit Enter to copy the contents to the clipboard.
Paste the results in a message here.

<computer_IP_address> - The IP Address of your computer, obtained from the IPCONFIG command above. (For Vista/Win7, the IPv4 Address)

<default_gateway_address> - The IP address of the Default Gateway, obtained from the IPCONFIG command above.

<dns_servers> - The IP address of the first (or only) address for DNS Servers, obtained from the IPCONFIG command above.

If you are on a machine with no network connection, use a floppy, USB disk, or a CD-RW disk to transfer a text file with the information to allow pasting it here.
Also,did this ever work?If so,any hardware/software changes ?
Safe mode with networking,probably a bit different on all pc's but I might try PF8 on boot up.
Or check it out in your user's guide.

This problem just started last night after I pulled my cable because I was picking up hundreds of malware items from some pop-up website. I ran a system cleaner and full-system malware scan before trying the internet again, which is when is didn't work. (Could some spyware have been able to affect my connectivity?) The only other hardware/software changes I've made are disconnecting/connecting the ethernet cable and disabling/enabling the connection.

I'm still trying to figure out how to restart in Safe Mode, but here's the results of the Command prompts:

A failure to ping is generally a firewall issue.Disable all firewalls,including windows default and any av suites that you have running.See if that helps.The ping that failed is the one to your pc.All others worked,so from the network level you seem to have a good network connection.(no dns type errors etc)
Now,when you said you ran a system cleaner,did that in any way mess with your registry entries ?

Thanks for the analysis; I don't what all of that means.

The only registry change that I remember it asked for my confirmation was a value added that I denied, because I was in the middle of the malware scan and didn't want to interrupt anything.

I have to leave for work now, though, so I'll have to try the firewall thing and post the result(s) later. Thanks again for the suggestion, though.

Ok: Disable all firewalls and for good measure any antivirus suites(Norton/Symantec/ AVG etc) that you have running

Apparently, my Windows Firewall has been off the whole time. (Turning it on didn't help, so I went back to off.) My Sophos antivirus won't open because it can't establish a connection, so I'm not sure if it's active or not. I'm pretty sure that those are the only firewall and antivirus I should have to worry about.

I don't want to be rude, but I'm going to try bumping this thread, because I really need to get this resolved and have no idea what I should try next.

It looks like you have ping the wrong IP address.192.169.1.102 isn't a valid private IP. If you could please open up command prompt and ping 127.0.0.1 and then post the results again.

Good eyes.Should be 192.168.1.102
Thanks.

Also.When did this start.Any hardware/software changes ?
Also,take a look at this:
The 306 error is related to issues with your proxy connections. A number of different things may potentially be causing the troubles, but a good place to start with your troubleshooting is adjusting your proxy connection settings in your Internet Options control panel.

(1) In your Start menu, select Control Panel.
(2) Open the Internet Options control panel. (If you are using Windows XP or Windows Vista you may need to select Classic View on the left before you can see Internet Options. If you are using WIndows 7 you may need to change "View by" to either Large icons or Small icons before you can see Internet Options.)
(3) Click the Connections tab.
(4) Click the LAN Settings button.
(5) Uncheck "Use a Proxy Server for your LAN". (If that option is already unchecked, try checking and then unchecking it.)
(6) Click OK to exit the LAN Settings dialog.
(7) Click OK to exit the Internet Options control panel.
(8) Restart the PC and try connecting to the Store again.

Unchecking 'Proxy Server' seems to have solved the problem, but do you have any idea why there was a problem so I can avoid doing it again?

hijack was the first thing that came to my mind when you said you're internet is opening up with a blank page. If i were you, i would go to security & HJT section of the forums and read up on how to clean an affected computer. You can also readhttp://forums.majorgeeks.com/forumdisplay.php?f=35, you may have some infected files still lingering around on your computer.

Sorry for taking so long to reply. I finally got this issue fixed and I appreciate everyone's advice. I'm not sure how, but from setup I managed to start a full system diagnostic, which allowed my to run my full antivirus program. After taking care of the quarantined items and running my malware checkers and cleaner, I was finally back to normal.
Thank you again for your time and advice.
