Connected but web pages don't open

[ROOTOY260]

My computer indicates that I am connected to my Comcast router, but when I click to access my homepage or any other webpage, I get a message that there is no internet connection.

My Network and sharing page reads:
Access: No Internet Access
Connection: Wireless Network Connection (home router name)

Any assistance will be greatly appreciated.

Hello and welcome ROOTOY mate two simple things you can try is to power off the modem and leave for a minute or two then power back on and see what happens.

You can just reboot the machine and I would be running these I any case

http://www.sevenforums.com/tutorials/433-disk-check.html



Did you install any drivers or software for that modem / router? If not post the model and let us look for one.

 

[ROOTOY260]

Thx ICit2lol,

I tried disconnecting then reconnecting the router but that did not resolve the problem.

I ran snf/scannow three times. Each resulted in the message "Windows Resource Protection did not find any integrity violations."

I ran Windows Network Diagnostics with results: "Problems Found Your computer appears to be correctly configured, but the device or resource (DNS Server) is not responding.

Also, I had previously received "Network adapter has been manually turned off."

In response to your question, I haven't knowingly downloaded or changed any drivers.

Router is xFinity Arris TG862 G/CT

Thx

 

[ICIT2LOL]

So the chkdsk did not come up with anything?

If you haven't run that one the do so and in Option 2 there are options to correct any faults .
http://www.sevenforums.com/tutorials/433-disk-check.html see pic for the repair items I mean.

 

[ROOTOY260]

Ran scan disk - scan, fix errors, and recover bad sectors - didn't come up with anything. No errors were found.

I ran windows network troubleshooters several times. Two problems were reported:

"Windows cannot access\\RAY-PC" and "Windows cannot find RAY-PC."

 

[ICIT2LOL]

Ray I might ask for some help on this one as there seems to be more to it than just a non net connection if that is ok by you?

To better assist you can you please follow this tutorial - http://www.sevenforums.com/network-sharing/300288-basic-requirements-before-posting-your-networking-thread.html. This can help us identify what may be causing your issue.

Your error messages seem to point to DNS which is the protocol used to translate legible host names into IP addresses. If that doesn't work then you can get symptoms such as no internet access or being unable to find a computer name.

More specifically we would be interested into looking at the IPconfig output so we can see what DNS settings are currently being used

Yes, ICit2lol, that's fine by me.

[Shadowjk]

Can you follow this tutorial and change your DNS servers to 8.8.8.8 and 8.8.4.4 and then test internet connectivity.

http://www.sevenforums.com/tutorials/15037-dns-addressing-how-change-windows-7-a.html

Please report back the results then we will work from there

Hope This Helps,
Josh

 

[ROOTOY260]

Didn't get connectivity after making the changes.

Windows Network Diagnostics resulting from checking validation box read "Troubleshooting couldn't identify the problem."

I noticed that, even after making the suggested changes, Network Connection 2 had a red X and "Network cable unplugged" Broadcom Netlink Gigabit Ether.
Don't know if that is of any relevance to you.

Thanks Josh this was just a little more than I expected and was going to post it in the help thread

 

[ROOTOY260]

Changed the settings and checked "Validate settings upon exit." The resulting Windows Network Diagnostics message was "Troubleshooting couldn't identify the problem." I tried opening several webpages but was unsuccessful -> "This webpage is not available."

I noticed that even after making the settings changes, Network Connection 2 has a red X and the message "Network cable unplugged. Broadcom Netlink Gigabit Ether..."

Don't know if that's of any relevance to you, but I thought I should pass it along anyway.

 

[Layback Bear]

Shadowjk I know very little of such matters but I do have a thought.

Could McAfee be causing this problem?

From ROOTOY260 SPECS.

Hard Drives 1863 GB TOSHIBA DT01 ACA 200 (SATA)
Antivirus McAfee
Browser Chrome

I will go back to watching.

 

[Shadowjk]

Aye Layback Bear! Very possible.

@ROOTOY260 - Can you try and disable any security related software that you have and then boot into Safe Mode with Networking. This will help us to determine if there is a third party application potentially causing issues with your connectivity. Once booted please test internet connectivity. If you can, also post an updated IPconfig when you are in safe mode.

Follow this tutorial (OPTION ONE ONLY) - http://www.sevenforums.com/tutorials/69585-safe-mode.html

   Note

Please replace all references of 'Safe Mode' with 'Safe Mode with Networking'

Lastly, could you shows us a screenshot of your HOSTS file contents. Since this can override the DNS settings I would be interested to see if there are any erroneous entries in there. To do so:

1. Open an elevated command prompt

2. Type in the following to change directory: - cd C:\Windows\System32\drivers\etc

​

3. Then type in the following afterwards: - notepad.exe hosts

​

4. Now copy and paste the contents of the opened file into your next post. It should look something like mine:

​

Now you can close everything!

Please report back your results,
Josh

Monday past I called the local computer tech who had recently replaced my hard drive and told him about my connectivity problem. He said it was caused by McAfee and that I should completely remove my McAfee Internet Security Suite. I did and, as you know, nothing changed. My point being that McAfee isn't running.

I have two others, iObit Malware Fighter and Malwarebytes Anti-malware ver. 2.01.
I don't know how to disable them, only to uninstall them so I didn't do either with them.

I booted to safe with networking and checked connectivity in that mode. No go - still unable to open webpages though windows continues to indicate that I'm connected.

Here is this morning's Ipconfig/all from safe mode with networking.

I will send HOST file in about 2 hours ... unfortunately I have a lunch meeting so won't be able to continue now.

 

[Layback Bear]

Back again.

From post # 16

iObit Malware Fighter

Anything that comes from IOBit can cause a Clean Install.
After having IOBit anything on your system I recommend do all the security scans after removing the program.
IOBit is known to bring little buddies with it and call home (China) which is scary.

 

[ROOTOY260]

HOSTS file

As suggested by Layback Bear, uninstalled iObit Malware Fighter and then ran my only remaining security program's scan. [Malwarebytes]

Here is the HOSTS file you wanted, Josh:

# Copyright (c) 1993-2009 Microsoft Corp.
#
# This is a sample HOSTS file used by Microsoft TCP/IP for Windows.
#
# This file contains the mappings of IP addresses to host names. Each
# entry should be kept on an individual line. The IP address should
# be placed in the first column followed by the corresponding host name.
# The IP address and the host name should be separated by at least one
# space.
#
# Additionally, comments (such as these) may be inserted on individual
# lines or following the machine name denoted by a '#' symbol.
#
# For example:
#
# 102.54.94.97 rhino.acme.com # source server
# 38.25.63.10 x.acme.com # x client host

# localhost name resolution is handled within DNS itself.
# 127.0.0.1 localhost
# ::1 localhost

 

[Shadowjk]

HOSTS file looks clean to me awaiting your results after the scan...

I will say, from a network connection standpoint your machine seems fine which makes me to believe something software based is messing things up. Sorry if you have already said, is this the only machine affected by this?

Josh

 

[ROOTOY260]

It is.

A laptop (also Windows 7), an iPad, and a Chromebook are all operating well on Home-1172.

I'm not sure which scan results you're awaiting.
