Solved Unusual traceroute in Win7

[Archangel83]

Hi I have been having some issues with my at&t adsl connection and decided to run some tests the first thing is I ran a speed test I got 5.55Mbps down and 768Kbps up this is normal did a ping check 14-25ms this is normal did a traceroute on windows

Tracing route to ny-monitor.dslreports.com [74.208.229.54]
over a maximum of 30 hops:
1    43 ms    42 ms    42 ms  u15150124.onlinehome-server.com [74.208.229.54]
Trace complete.

What only 1 hop! This is for any and all servers I try to use on a traceroute what is going on here is this normal for my connection? Or is it an error with my OS? I have no vpn configured so why don't i see more then 1 hop?

Do you have ZoneAlarm installed? This is common for ZoneAlarm.

Also, what do you get if you use pathping <destination>?

 

[Archangel83]

The only firewall I have is the one with windows and here is the pathping

Ok, I also assume you are not using a proxy or VPN.

So please go to CMD prompt and type 'ROUTE PRINT' (m inus the quotes), and post the results back.

thanks

Yes you are correct I have not setup a proxy or vpn to run on my machine.

Ok, your routes look clean.

With no Virtual machine, proxy, VPN or ZoneAlarm, that leaves one of three things..

Since the problem also shows with path ping that pretty much eliminates the windows commands. You could do a SFC /scannow but I doubt it would fix the problem.

It seems to me, and from what I can read on other forums that the problem might be with the ISP. Has this problem existed from your place with a different modem?

What happens if you go to somewhere else with a different ISP with your computer and modem? (that would mean doing som reconfiguration, and might be a little too much work).

I believe it's my isp blocking the traceroute as it works when i connect to my neighbors wifi and he has time warner. I tried his pc on my network and his machine gave the same 1 line 1 hop result. Thanks for your help but as I suspected it was my isp.

It's my router I reset my dsl modem back to factory and was just working off that and all tracert were normal. Bridged the modem and went back on my router and it was a single line tracert. It has something to do with assigning static ip's on the router if I disable that and allow dhcp on the router to control each device then I get a normal tracert problem solved.

That's interesting. I have my modem and router configured in bridge mode and I get all normal tracert's.

I have them configured with a static IP and DHCP is enabled on the router only, since it is the only device that allocates IPs (Turning on DHCP on the modem when it is bridged is pointless).

thanks for sharing the solution with us.
