New U-Verse Customer - Reno , NV
Hi all,
I recently switch over to ATT U-Verse from Charter Communications. I was a happy Charter customer for 7 years and enjoyed a blazing fast 35mbps/2.5mbps connection with sub 30ms latency to the major WestCoast POPs. The reason I switched was because my home was pre-wired with Fiber, expanded channel lineup, and only 400feet from the VRAD. Scheduled installation was great, the tech was ontime and the installation took 6 1/2 hours. 24 hours later and I've impressed with the quality of the TV portion of the service, but the high speed internet is terrible.
1) The routing seems to be fubared with my connection, I have a 100mbit dedicated line at work which is also serviced by ATT. Before on Charter I could reach my work's network in 5 hops with excellent latency. Now I reach it in 12 hops, never using the ATT backbone to reach the network, instead it chooses Level3 as it's desired path with several timeouts along the way.
2) Doing an ip2location on the public WAN IP assigned to my router, shows that I'm located in Washington D.C. when I'm actually in Reno.
3) Running a speed test at http://www.att.com/speedtest/ results in a 9mbps/2.7mbps speed, no where near what I'm paying for. Below are the displayed stats from my 2wire gateway. I have 30 days to cancel this service, and will do so if I don't find a way to improve the internet portion of this service.

No, it does not qualify as a problem. It means that those hops are not responding to ICMP requests.
But the fact that you can get other types of traffic to the other end (and indeed, the endpoint responds to ICMP within 70 msec) means that the hops are routing other traffic just fine.
This is why traceroute is not a very good troubleshooting tool. Many routers on the Internet treat ICMP packets as very low priority, and in some cases may not even respond to them. That doesn't mean anything is wrong with the router.

Please download U-Verse Realtime, install it, and post screenshots of the IP/Profile tab, Bitloading tab, Error Table tab, and Coax/HPNA tab.
To post screenshots here in the forum, you will need to upload them to a photo sharing site, like Picasa, Google, Photobucket, ImageShack, etc.

I don't see much wrong with your line except the downstream power level. It seems too low for your distance from the VRAD. However, it doesn't appear to be causing any problems -- the error table looks fine.
Try a few other speed test sites, in particular http://www.speedtest.net . Try several different servers and tests so that you get a good feel for what your download speed truly is.
As far as your other issues, the non-optimal routing from home to work could be for several different reasons, but isn't by itself causing you problems, is it? My home to work connection is about 14 hops as well (non-AT&T on the work side), but the round trip time is always around 45 msec.
The IP geolocation issue will probably fix itself in several months. I believe Reno is a relatively new location for U-Verse, and AT&T probably does not have proper registration of the netblocks in use out there yet, so the IP geolocation services will have the wrong info for a while. Once AT&T properly registers the netblocks the location will get corrected.
Are you having any other specific issues that indicate low performance? If not, there isn't much AT&T can do. Unless you can show them something along the lines of 300+ msec pings or maximum 3 Mbps transfer rates, they're going to tell you they can't fix what isn't broken.

But don't you find it just a little bit strange that that the path the connection chooses is through Level3's backbone and not it's own? (ATT)
Why is it traversing into foreign AS's rather then stay on its own, AS7018?

That does seem odd, but we don't know the particulars of the routing policies being applied. For whatever reason, AT&T might have some kind of transit deal in place with L3 for this particular route, perhaps in exchange for some other transit deal that they're giving L3 in a different part of the network.
Again, unless you can show AT&T that the routing impacts the performance expected from a residential Internet installation, they're likely not much they can do.

Oh I have no doubt they can do it. The real question is will they, probably not.
I could always saturate my connection just enough to impact performance and engage them at that point. That's pretty lame though.

Check this out, tracing from work to my u-verse at home. 4 consequtive traceroutes, in two of them an extra 2 hops are in play. Never once did it touch the L3 backbone.

Would this qualify as a problem? 100% loss on Hop 14 and 94% loss right before my RG.

I agree with you. Having had some time to use the service more, I am satisfied with the performance all around. Although the high speed internet isn't nearly as good as my previous Charter connection, it's still very good and the TV portion far exceeds the Charter offering. Since it is still new in the area, perhaps it will improve over the next few years. Thanks for all the feedback.
