Sprint ##DATA tuning (changing Home Agent)

I've tried the HA's for Kansas City, but it made things worse. Looks like the HA's are sparce in the West.

Physical Location= Salt Lake City
68.28.57.76=Anaheim(Los Angeles Area)
68.28.49.76=San Jose

Also note that even with the HA set to Los Angeles, traffic is still routed up through Stockton and San Jose before popping outside of Sprint's network. For IPs in the So. Cal area, the pipe Sprint uses from San Jose back down to Los Angeles used to be a bottleneck, but Sprint re-routed a few months ago and performance has been much better since. This from having looked at far too many traceroutes awhile back.

Forgive me if I'm asking something that's already been answered...

Is there any general rule of thumb for home-agent changes? eg, should one avoid not going outside the "home area"? Or does anything go? Should one swap the primary for the secondary agents or does that typically matter?

For what it's worth, I live in Chicago (in a neighborhood called Wicker Park which is in the city, much closer to downtown then the suburbs), and I'm finding that throughput tends to behave better when setting Indiana home agents, rather than Chicago, IL ones. Does this make sense?

Also: should one avoid changing anything other than the "Primary HA Adress" or "Secondary HA Address" fields? Are these other fields useful for anything else?

It wouldn't be surprising if an HA closer to you is slower than one further away. It depends on the performance of the network path and some shorter paths could be more congested than longer paths, but it might impact latency if the HA is across country.

The card connects to the primary address first. If it can't reach that HA, it will try the secondary.

Try experimenting with several HAs in your region (KC/Chicago/Indy) and set the best to primary and second best to secondary. When traveling, if you are not satisfied with performance, try setting the HA to region of your travels.

I am in Southern FL, West Palm Beach.. and so far the best I found was out of Kansas City... Very Weired, being that the closest for me is Atlanta..

My HA was set to IL and MI...

Anyone have any ideas??

Im kinda a newbie... Thanks

It's possible an HA further away will have better performance. It all depends on the traffic on the path to each HA and location of destination site. But I would expect ping times to potentially be less with an HA further away, depending on the destination location.

I am getting ping from 300-500... and the best I have gotten dl is 1100mbps... I have messed around with changing the HA's, but I believe it is because I am on the 1st floor of a 3 floor Apartment Complex with buildings surrounding me... Thanks for the reply tho! Very Happy

How do you get to the ##DATA on a PX-500? Any help would be appreciated. Also I'm in Portland, Oregon - anyone have HA's on this area? - thanks

BigDave is right, this thread is really long, but tons of awesome information. I have been reading the forum here for about a month since I got my Sprint U720 service.
Being a over the road truck driver who is a bit computer savvy Smile

I had to have my internet and T-Mobile internet was NOT fast enough. lol Anyhow, I bought my card at an Interstate Connections booth at the Petro truck stop in Atlanta, GA and got my service going there. I was wanting to change my HA as right now it says I am in Atlanta and then connecting to IL and MI for servers, WOW talk about a hop! Given I am in the midwest and towards the west coast more I thought that could help me with disconnects and better ping times.
I called Sprint Tech support, same horror wait story as everyone else, and the tech said he would have no problem giving me my msl code except since I didn't buy my card from Sprint and got it from Interstate Connections I would have to contact them. Heh, this is a booth where the people change more often then most people change their underwear and honestly they are probably worse then Sprint for any kind of service.
Anyone heard of this for getting the msl code? If so, any thoughts to a solution to obtaining the msl code? Or should I consider that I am S.O.L. at this point?
Awesome awesome forum, I actually felt bad having to post with all the great information I have found so far, but just couldn't find this. Thanks so much!

nightdriver, keep trying second level support as you may find someone who can give you the code. Might have to try another story other than needing to activate. Be point blank that you travel and need to change the HA, so simply need to code. An advantage of buying from this site is that they'll give you the code with no questions.

jerlarsen, this works with Pantech too The screen will look different and the HA might be hiding in another tab, but the instructions in first post should get you close enough to finding the HA address easily.

nightdriver, in addition to what xenophon said, I wouldn't bring up the fact that you didn't buy the card from Sprint. Sometimes it's possible to give them too much info. Just keep on trying. So far, if you have enough time to do so, (and I would imagine if anyone has the time on their hands to sit on hold it would be an over the road truck driver!! Very Happy

) I haven't found anything you can't get done if you're willing to call until you get someone who will do it. I know it's nuts but that's the nature of the wireless beast. Very Happy

The right hand doesn't even appear to know there is a left hand, never mind knowing what the left hand is doing!!

has anyone figured out if there are any speed tricks in the other ##DATA Settings? HA-Secret, MN-HA-SPI, MIP Settings, etc?

Advance apologies if this has been covered. I didn't read all 15 pages of replies. (Yet.)

Two questions:

1. Has anyone figured out how/where to find and change the home agent with a PX 500 pc card modem?

2. Isn't the Sprint activation code something universal and benign like six zeroes? It was given to me when I first signed up and I'm trying to find it, but that is my memory. Or that may be for Nextel or for Verizon, both of which I've had as well...

I really need to experiment with this tweak. I am near Santa Fe, New Mexico, and am getting downloads of 10KB/sec.... which is like 1995 dial-up speeds. I get the same -- or worse -- performance in Albuquerque.

I have experimented with settings, moving it from automatic to EVDO only and having it on Roaming. On Sprint-only I barely get 2KB/sec downloads WHEN it will hold the connection. I average -86dB signal, though occasionally it tells me it is roaming and the signal drops into the low -60s. However, I get terrible download speeds then. (Inexplicably.)

And interestingly, the 1xrtt icon is blotted out with an exclaimation point in a yellow triangle when I open the Device Info and Diagnostics screen in the Sprint connection manager module. I would think that even 1xRTT would be faster than the speeds I'm getting with EVDO here. I am using a dual-band amplifier and external antenna to get those speeds. Without them I average 6 KB/sec downloads.

And I don't seem to be able to get any 1xrtt signal -- at least not according to Device Info and Diagnostics.

All helpful advice welcome.

Thanks,
kwc

First post here.

Just signed up and i have a px500 with Vista Ultimate on my x61t (near downtown los angeles). Followed the instructions and it was easy.

Was getting speeds fluctuating a lot from 300-600Kbps down (4-5 bars, -80 to -100s dbm). Switched to the KC HA from the San Jose, Anaheim area and i am up at 800-1000Kbps down (150-200 latency). This is awesome!! Hope it holds. Did two speed tests today so far and i plan to do more.

This just seems a lot more stable. Download speeds were all over the place before. Makes sense since there's probably lots of traffic in LA. I am not sure if this is correct reasoning, but i like the results so far.

Thanks a lot xenophon
