New Linksys WRT54G

I just bougjt a new WRT54G and ping plotter no longer works. I can go into dos and do trace routes with no problem.

When I use Pingplotter It shows the hops for one or two passes then it just shows the last hop and AVG time to that hop bleeds down to 0.

Any ideas?

I have changed the Router to allow ICMP through and again DOS traceroutes work fine.

We don't have any specific reports on that *specific* router, but there have been problems in the past with Linksys routers doing similar things.

The first thing you should do is make sure you have the latest firmware for your router.

If that's not an option, or it doesn't help, then you can change the settings in PingPlotter so it waits between sending packets. See here for details:

If none of that helps, feel free to post back here with what you've done and we'll see what we can do to help.

I have made sure that the router is up to date. Its a v5 with firmware 1.00

Made the changes you recommended to the PingPlotter settings with no improvement...still can't see full traces...f

It's really, really likely this is a bug in the Linksys bios, confusing packet responses. We've seen it before, with similar symptoms.

If you want to create a .pp2 save file and send it to support@pingplotter.com, we can look at this and see if the symptoms match what we've seen with other routers.

Hi,

I just bought the exact same router and I'm having the same results. When I initially start Ping Plotter it works and shows all hops for about a second, then it only shows the destination hop with nothing else. I updated my firmware to 1.00.2 (Oct31,2005) but the same results.

I can save a PP2 file and send in if this will help. How long do I need to run Ping Plotter for before I save the file?

I am forced to use a very unreliable ISP so I'd love to get it working again.

Can you send us a request via email (support@pingplotter.com)? We have a packet capture tool that we've been using internally lately to troubleshoot some routers with similar problems - it would help us understand this more if you could install it and we could grab a few sample sets of packets.

I too can confirm that the Linksys WRT54G v5 breaks Pingplotter. I tried several different versions of Pingplotter on different computers on a network with the same results. After the first trace is made, it shows only the last hop - but the time in ms shows the first hop. Running tracert from the command line has no issues. This is not my network I was troubleshooting, so I can't send you a log. You might want to purchase one of the routers (v5), just to see for yourself. Very odd.

We've made some progress on getting this working.

First, you need to upgrade to the lastest bios for the router (1.01.2 as of December 5th, 2005). Next, you need to set PingPlotter to "Ignore First Hops" and set it to start at hop 3. Do this via the "View" menu.

Once you've done this, we have some evidence that things work correctly (except for not being able to report on the first 2 hops).

If anyone else has any success with this, please let us know.

Same router, same problem. The latest firmware available from LinkSys is 1.00.4, dated 12/9/2005. I have installed that, and following the instructions in the above post, it seems to be working correctly.

Same thing - Same new linksys router. I won't chase firmware's until we see some evidence of working. I did try the 3rd hope workaround. I do get some output now. However, I don't get any totals and my last hop is experiencing 100% packet loss.

I am running version 2.60 registered.

Hi, Mickey.

There's been a number of reports that starting at hop 3 works relatively well. We don't have a V5 router here, though, so we've not explicitly tested it.

If your final destination is getting 100% packet loss, you might have a look at some of our knowledgebase articles on this topic to try and troubleshoot:

You might start out here:

and

Make sure you're trying to trace to a destination that response to ICMP echo requests - www.nessoft.com is one site that does.

Let us know if this helps (or not!).
