I have a problem with my internet connection and my ISP is unwilling (or perhaps unable) to resolve it. The connection is wireless broadband. According to the CPE (at 172.16.1.1) it is a Mikrotik V4.5. Since I do not have a log in password, I can not provide any further information about the CPE.
Several weeks ago I noticed that I could no longer access the website http://www.blacklistednews.com from any computer on my home network. If I use my laptop in another location (a friends house, a public network, etc.) I can access the website.
I have not noticed if any other websites are blocked.
I have contacted my ISP several times regarding this issue and they have responded by asking me questions such as “is your computer turned on?” and “are you connected to the internet?”
At one point they informed me that they connected to my CPE (from their office) and could not see any problems, therefore the problem must be with the network settings on my computer.
Does anyone know what could be causing this, or how to resolve it?
This doesn’t look like a website that an ISP would block. You can try accessing the site through a free proxy or a VPN service (ex: http://usaip.eu) to verify if it is a local problem. If you can access it, then probably your ISP is blocking it and you will be in a better position to ask for an explanation. If you still have problems through the VPN or proxy, then it is possibly a local problem.
I am able to access the site using a free proxy service.
I still suspect the problem is with the CPE. Since my previous post I have found several more addresses which appear to be blocked.
Ping:
204.27.61.74 (100% loss)
204.27.61.75 (100% loss)
204.27.61.76 (100% loss)
204.27.61.77 (100% loss)
204.27.61.78 (100% loss)
204.27.61.79 (100% loss)
*these all return normal pings from outside of my network.
Its all good as long as I can access using a proxy. I am just disappointed with my ISP’s lack of support.
I like the idea normis suggested. But while you wait for the tech to show up, try a traceroute to see where the connection is being stopped.
/tool traceroute www.blacklistednews.com
ADD: You shouldn’t need to reset the CPE. Unplug it just before you call tech support. If it doesn’t answer their connection request, they will probably send a technician.
Several months before this issue began, I had to unplug the CPE after installing a new UPS. It reestablished the connection right after powering it back up. I will try it again later today to see if it helps.
I just ran traceroute and the results are different than they were two weeks ago.
Previous traceroute results:
traceroute to 204.27.61.74 (204.27.61.74), 30 hops max, 40 byte packets
1 172.16.1.252 (172.16.1.252) 3000.831 ms !H 2998.072 ms !H 2997.885 ms !H
*172.16.1.252 is the internet IP address of my router, which is connected to the Mikrotik CPE gateway (at 172.16.1.1)
It is using a different gateway now. Two weeks ago it was trying 172.16.1.252 for non-local addresses. Now it is using 172.16.1.1. That new one sounds correct to me.
However, I will guess that the new challenge is out of your ISP’s control. That timeout looks way down the list somewhere.
ADD: Here is mine. I cut out the stuff that was different. Start reading yours at line 7. Some of these ips appear to be the same subnets. (add: line 12 below is the same ip as your line 11)
