All normal web browsers on all computers on my home network can not connect to most or all webpages. sometimes I can get google.ca to open but not always. Windows Update connects. Online games also work. The only web browser that I can use is Tor Browser I think because Tor gives me a different IP address. I have been reading fourms and trying everything to fix the problem for about a week now but nothing has worked so far. I have searched for malware and viruses, I have done the ipconfig stuff, I have tried everything I could find online only difference is I have not seen anyone else mention that Tor Browser is working for them and I feel like this is a major clue to what the problem is. Im starting to think that my IP is being blocked on purpose. I have even had my ISP remote connect to my computer and they did a few tracert tests and say that the information is getting lost along the way and said they would work on it but it has been days with no change. Any thoughts? Please help!

Hello,

In order to find out what is going on you really need to start with the basics. On your computer open a command prompt. Under Start, All Programs, Accessories, Command prompt. You will get a window that takes you to the old msdos prompt.

  1. Can you get to the internet. The following command will attempt to ping a public DNS server.:

ping 4.2.2.2

You should get someting like this back:

C:\Users\Rodney>ping 4.2.2.2

Pinging 4.2.2.2 with 32 bytes of data:
Reply from 4.2.2.2: bytes=32 time=32ms TTL=49

Reply from 4.2.2.2: bytes=32 time=29ms TTL=49
Reply from 4.2.2.2: bytes=32 time=43ms TTL=49

Ping statistics for 4.2.2.2:
    Packets: Sent = 4, Received = 4, Lost = 0 (0% loss),
Approximate round trip times in milli-seconds:
    Minimum = 29ms, Maximum = 43ms, Average = 33ms

You probably will so step 1 is done.

  1. Can you resolve DNS names. Basically this means can your computer ask the internet to convert a domain name to an ip address and can you get to that address.

    C:\Users\Rodney>ping google.com

    Pinging google.com [74.125.227.206] with 32 bytes of data:

    Approximate round trip times in milli-seconds:
    Minimum = 12ms, Maximum = 14ms, Average = 12ms

If you get something like this then you can resolve names.

  1. If not then you have problems with the system your computer is set to ask the information from. Find out what ip your computer is asking to resolve the names. Try asking for a name to resolve:

    C:\Users\Rodney>nslookup google.com
    Server: UnKnown
    Address: 10.0.0.1

    Non-authoritative answer:
    Name: google.com
    Addresses: 2607:f8b0:4000:804::1000
    74.125.225.226
    74.125.225.227
    74.125.225.228
    74.125.225.229
    74.125.225.230

  2. If you did not get something like this then ask a specific name server for the info:

    C:\Users\Rodney>nslookup google.com 4.2.2.2
    Server: b.resolvers.Level3.net
    Address: 4.2.2.2

    Non-authoritative answer:
    Name: google.com
    Addresses: 2607:f8b0:4000:800::1006
    74.125.225.233
    74.125.225.229
    74.125.225.224
    74.125.225.228
    74.125.225.238

If you get something like this then your problem is that your computer is not asking the right server for information. This could be due to your router being wrong but I would contact the company you get internet service from and see if they can help.

Thanks for the quick reply Rodney. I tried what you said and I guess my computer is not asking the right server for information if I read you right. I have no idea why this happened because it was working fine before. My ISP is Comwave and I don't think they are open until Tuesday due to it being Thanks Giving long weekend here. It ticks me off because like I mentioned before they remote connected to my PC (Thursday) and using Command Prompt they did ipconfig /flushdns, /release, and /renew with no luck then did a bunch of tracert tests as I watched from my end and then told me that the information was getting lost along the route and that they would have to reroute my connection and they said it would take up to 24 hours for them to do it but they probably forgot about the long 4 day weekend. And for days before that they had me disconnecting and reconnection and resetting the modem and the router over and over till I was pulling my hair out screaming at them that everything was good at my end then they told me that I probably had malware or viruses preventing my browsers from connecting. Again thanks for replying and helping me figure this out. Below I pasted the results from Command Prompt. Do you have any other sugestions I might try to fix it myself?

I think that in his last paragraph "If you get something like ..", rch [Rodney] meant "If you did not get something like.."
However. You do realise that you can copy from a cmd window? Rclick in top border for best use of options. Then we don't get typos.
eg. from your "nslookup google.com" result it appears that 8.8.8.8 is your DNS server (cf result with "nslookup google.com 8.8.8.8"). Confirmable via "ipconfig /all", or thru the control panel/network connections gateway.
But those things you tested are working for you.
If all browsers are down then perhaps your TCP/IP stack is corrupted, or sockets.
How did you get on when your ISP woke up?

Hello,

Based on the output from your system you are resolving names ok. The thing that I did not read closely enough the first time was the comment on your using Tor Browser. I am curious as to why you would think that Tor Browser is the only one you can use? All a browser really does is to make the web pages you receive from servers have the proper format on your screen. Tor just gives you the ability to view the internet anonymously.

There is an artile you might want to review on Tor about a problem just detected.

Tor Browser Attacked
