Hello, everyone out there. I'm having quite a bit of trouble with my internet browsing lately.
Yesterday, my computer initiated an automatic update the way it always does, following with an automatic reset after five minutes of me ignoring it. After my computer rebooted, the problems began. My Firefox browser could not display any web pages after this update to my operating system (Windows xp Home Edition). Every web page I tried to load said something like "Connection interrupted while the page was loading. Please try again"
Needless to say, no matter how many times I tried, it simply would not work. Now, the internet is obviously not having some freak incident because I'm able to post here. And the two other computers in my house connect just fine as well. I'm posting here on the affected computer by booting Backtrack 3 from a usb drive, so my computer has a connection to the web. And the strangest thing, I think, is that my Windows Live instant messenger still works on Windows. I've tried loading several different web browsers to Windows such as Google Chrome and Avant Browser all to no avail. My Internet explorer also can't connect.
So, my question is: Why can't my web browsers connect after a normal, routine automatic update to my system while my instant messenger can?
Any help at all would be greatly appreciated.
Thank you for your time.
Goto Start / Preferences / Control Panel / Internet Options / Connections / Properties and deselect all checkboxes.
Then give it another try and repost the result.

Have you also checked the proxy settings in the alternative web browsers?
Is the internet connection a private one or is it a connection at work?
Because at work, you might have to configure a proxy. In that case you have to ask the administrator for the correct settings for your browser.If it's private, I guess you don't have a proxy server running and so the browser should be configured to direct connection.

I am on a private network, so I don't think I use any proxy servers. (I'm not too keen on what a proxy does or how they work)
As far as connection settings, the Firefox I'm running on this Linux is set to "Use system proxy settings" as seen in this screen shot: http://i258.photobucket.com/albums/...
However, the Firefox on my Windows system is set to "Auto-detect proxy settings for this network"
The Firefox on my Windows is also one update behind the current 3.5.2.

If you set the proxy settings to no proxy, you definately know, that no proxy will be used.
If you set it to "Use system proxy settings", did you really know, that there is no proxy used.
E.g. Linux uses Squid as a proxy, if it's installed.
So if Squid is not configured correctly, you won't get access to the Internet via browser.Please send a reply, if you solved the problem !!!

Ok, so what does a tracert on Windows or a traceroute on Linux show?
E.g.:
tracert google.comor on Linux
traceroute google.comPost back.
Please send a reply, if you solved the problem !!!

When I run a traceroute on Linux, my results are as follows: http://i258.photobucket.com/albums/...
I will have to get back to you on a tracert with Windows since I'm pressed for time right now; I have to go to school soon. Thank you for your help thus far.

Ok bad idea on Linux.
Under Linux it's better to use mtr for the traceroute, because traceroute itself has some problems.So unter Linux try
mtr google.comPlease send a reply, if you solved the problem !!!

can you from the dos prompt ping these two things c:>ping 4.2.2.2 or c:>tv.com
if you can ping 4.2.2.2 you are connected to the Internet, but if you can't ping tv.com, you have a local DNS issue, you can use 4.2.2.2 as a local DNS entry on your computer.

Here are some results from the mtr: http://i258.photobucket.com/albums/...

I paused it at a couple points because it didn't look like it was going to stop any time soon.
As for the tracert under Windows, here's what I got: http://i258.photobucket.com/albums/...

I'll have to try that. Thanks for the suggestion.

All these traceroutes are ok.
So everthing did work as expected.
So there must be a problem in the browser preferences.
If you're using Firefox, it's easy to check.
In the profile folder of Mozilla Firefox, there is a file named prefs.js.
This file contains all settings for firefox.
So close firefox and rename the prefs.js to prefs.bak.
Start firefox and try to access the internet.
During firefox startup, a new prefs.js will be created.
If the problem persists, you can simply close firefox and rename prefs.bak to prefs.js, to get back your previous settings.Please send a reply, if you solved the problem !!!

I did that and it still isn't working. I really wish I knew what happened when my computer updated itself.
0
Yes, but when this happens on both, Linux and Windows, it's most unlikely, that it has to do with auto update.
Is there a bad configuration in your router?
Most common routers do have filter functionality for webbrowsing.
Checked that?Please send a reply, if you solved the problem !!!

In my router configuration, should I be looking for over-zealous firewall settings? Or something else? I've only ever used my router's settings menus to make a wireless network, so I don't really know what I'm doing.

Here are my results for pinging 4.2.2.2 and tv.com:

If you've never change such settings, except provider data and wireless settings, there is no need to work on it.
Here is another, a bit simpler question.
Have you checked, whether your browser is working in offline mode?
In firefox you will find this setting in the file menu.Please send a reply, if you solved the problem !!!
0
I have made sure that Work Offline is disabled. Unfortunately, it wasn't in offline mode when I looked. I honestly wish it were something so easily overlooked.

Open a command prompt and use the following command (in Windows):
netstat -an 5Then open your browser and try to surf the internet.
Switch back to the command prompt and check, what happens when the browser tries to connect from a high port to port 80.Please send a reply, if you solved the problem !!!

Here is what happens when my computer is attempting to surf the web: http://i258.photobucket.com/albums/...
In the bottom of my browser it says "Waiting on example.com" for a while and then comes up with the error. So it seems to see the site, but doesn't really do anything else.
0
That indicates, that the browser did not make any try to connect to the internet.
And the main question is, why are there 2 IP addresses, 192.168.1.44 and 192.168.1.46 ???
Both IPs are in the same range, what did not really make sence.How many network cards are in that PC?
If more than one, do both have configured a default gateway?Please send a reply, if you solved the problem !!!
0
It has a wireless network card and a normal one. I don't really know what a default gateway is, let alone how it would be configured. I'm not very familiar with any of this stuff. When I got the computer, I installed windows xp, put all the recommended drivers for the model it is on it,and plugged it into the router and it worked automatically. It also works when I unplug the Ethernet cable because we have a wireless network, too.
0
You should only use one connection at a time, otherwise, Windows tries to use both connections and gets confused.
Try to use only wireless or only wired connection and post back.
Btw. default gateway is the direction, windows should use, if the requested IP address (website or whatever) couldn't be found locally.
So if you have a router, the default gateway should point to your router.
Windows tries to connect to example.com and didn't find it locally. So it asks the router. The router does it the same way. It tries to find example.com, couldn't find it and asks your ISP.
That's the way it works.Ok, try only one connection type as mentioned above and post back.
Please send a reply, if you solved the problem !!!

Alright, I tried disabling the wireless network and just using the wired connection; didn't work. Then, I disabled the wired connection and unplugged the cable to make sure and it still didn't work.
0
Have you restarted windows after you've made the changes?
Might be necessary to do that.
Also do an ipconfig /all and post the result.
This will show, whether ip, subnet mask dns and default gateway are correct.Please send a reply, if you solved the problem !!!
0
I restarted with the disabling one and then the other, but with no luck.
And here's my ipconfig /all: http://i258.photobucket.com/albums/...
0
In your screenshot you can see, that both network cards are still activated.
You can disable the network cards from the Control Panel / Network Connections.
Rightclick the card you want to disable and choose disable.Please send a reply, if you solved the problem !!!
0
I did the command while both were active. I did all the disabling stuff twice, and it didn't work, even with a reboot.
0
This could not really happen.
If the problem does only exist in windows, that might be a virus.
If the provlem does only exitst in Linux, that might be a missconfiguration.
The only thing I could suggest for testing is, to download and burn a Linux Live CD, boot from that CD and try to access the internet.
I've never seen, that Linix Live CD does not work.If you will test this and it works, both thing may apply to your system.
Linux missconfigured and Windows infected.Please send a reply, if you solved the problem !!!

I've run Ubuntu from a live disk and the internet worked, I ran Linux Mint from a live disk and the internet worked, and I've been running Backtrack 3 live all week and the internet has been working fine as well. So, my different linux distros are good. I don't have any OS other than windows installed on my machine, though.
I never thought of a virus, since I scanned my computer and it came up clear. Do you have any recommendations on an antivirus program? I use Avg free right now.
0
There is another free antivirus, that I use by myself.
