| Evdo Tweaks and Tuning There is alot of information on other sites about tuning and tweaks to help speed up your Evdo/1xrtt connections. While 1xrtt may recieve little to no help from them, sometimes the EVDO side gains significantly.
I dont take credit for any of the information posted below, I just put it together here for people to view.
One of the utilities you can download to adjust your settings is Dr TCP from here on BBR. I just wouldnt recommend changing anything that you dont know about.
One of the first adjustments you can make is this,
TCP Receive Window Size = 65536
##DATA tuning, aka HA (Home AGENT)
To see/change the HA Address, you must acquire the MSL code from Sprint. If you've activated the card yourself when first purchased, the code they gave you to activate is the MSL code. Or you could call the tier 2 data group 866.818.1944 (sometimes long wait) and tell them you need to activate your card and need the Activation Code. They should give it to you with no issues. They'll ask for your ESN number written on card or the phone number of card which can be found in Device Diag in Connection Manager. They also might ask for your account password. If a rep does not head down that path, hang up and call another.
Once you have the 6-digit MSL/Activation code...
- Run Sprint Connection Manager
- Must be disconnected from EVDO (disable NDIS if using it)
- Move mouse over 'Go' button and leave pointer on top of it
- Type in caps... ##DATA
- Enter MSL code
- A screen like this should appear for Novatel cards...
For Sierra Cards-
 and 
Experiment with primary/secondary addresses below but be sure to write down the original address on the card in case you need to go back to it. Update: Or you can do an 'Update Profile' in connection manager and it will set back to defaults. The primary address is first used when connecting. If that fails, it will use the secondary.
On Vision and PowerVision phones, dial ##DATA#. You'll need the MSL code to change the HA address, which is harder to acquire for phones. For some phones, this universal code might work... 040793
Here are the addresses of Home Agents around the country. The tools used to determine the location are only about 80% accurate, so these locations may not be exact. Set the HA to one near you (but try others). If traveling, set to the region of your travels. Thanks to cyb3rshad0w for cross-checking this list...
68.28.49.76 San Jose, CA Area 1
68.28.49.77 San Jose, CA Area 1
(could be Stockton)
68.28.57.76 Anaheim, CA Area 1 (or San Jose)
68.28.57.77 San Jose, CA Area 7 (or Anaheim)
68.28.81.76 Kansas City, MO Area 2
68.28.81.77 Kansas City, MO Area 2
(could be Omaha)
68.28.89.76 Kansas City, MO Area 2
68.28.89.77 Kansas City, MO Area 2
68.28.113.76 Pennsauken, NJ Area 3
68.28.113.77 Pennsauken, NJ Area 3
68.28.121.76 New York, NY Area 3
68.28.121.77 New York, NY Area 3
68.28.145.76 Chicago, IL Area 4
68.28.145.77 Chicago, IL Area 4
68.28.153.76 Roachdale, IN Area 4
68.28.153.77 Roachdale, IN Area 4
68.28.177.76 Fort Worth, TX Area 5
68.28.177.77 Kansas City, MO Area 5 (possible DNS config issue, likely Ft. Worth)
68.28.185.76 Atlanta, GA Area 5
68.28.185.77 Atlanta, GA Area 5
(speedtest.net says in Houston)
68.28.241.76 Relay, MD Area 7
68.28.241.77 Relay, MD Area 7
(speedtest.net says in Florida)
68.28.249.76 Atlanta, GA Area 7
68.28.249.77 Atlanta, GA Area 7
This is it. There are no other home agents known.
Here is a quick way to determine your assigned 'area' w/out needing MSL code. This will at least narrow it down to two possible HAs...
»/mspeed?whoami=1&w=
Example:
DNS: area4.spcsdns.net (must be set to Indiana or Illinois)
Another way is to do a traceroute (tracert command in Windows) to some website and compare the path of IP address locations with this tool (only 80% accurate)..
»www.ipligence.com/geolocation/?l···&search#
To compare your speeds with different HAs...
»www.sprint.com/speedtest (sprint's test site)
»/stest (coasts)
»www.everestkc.net/index.php?module=speedtest (midwest)
»speed.nap.wideopenwest.com (midwest)
To check latency from command line, 'ping www.google.com' or website near you. Lower is better.
Rev0 typically does 180ms-400ms, 130ms is about the lowest.
RevA typically does 100ms-200ms, can be as low as 50-80ms if near tower with few/no obstructions.
Latency can be much higher with poor signal, thick or many walls, when below ground or if HA is set far away.
More details:
- When traveling, the HA you are assigned to may cause traffic to bounce twice across country. If you live in NYC and are assigned to a NY HA, but then travel to LA and visit a website in LA, your traffic (worst case scenario) will likely bounce from the LA tower to the NY HA to the LA website back to the NY HA to the LA tower and to your laptop. That's a lot of unnecessary hopping across country. If you have performance problems when traveling, try setting the HA to the region of your travels. Statistically speaking, if traveling often around US and visiting websites everywhere, setting the HA to one in the Midwest may be the best compromise.
- Mac/Linux and router users. You must change the HA with Connection Manager in Windows. The settings are stored in the card so when used with non-Windows, the HA setting will still work.
Warning: Use info at your own risk. Don't change other settings unless you know what you're doing.
Update: Sprint seems to have improved HA bandwidth performance issues by turning off the compression servers. The HA you point to may be a factor if you travel across country but in general, the HA is less of an issue than in the past. Latency/ping times could still be impacted, especially for RevA users. Update2: Many still see bandwidth improvements by experimenting with different HAs.
BTW: This is a CDMA thing, not a Sprint only design, so Home Agents are likely done this way for Verizon and Alltel as well. I've tried to find a way to change Verizon HAs but with no luck.

| I don't understand the screenshots for the sierra wireless cards. Do you change the HA for Profile 0 or Profile 1? If I do profile 1, the settings are erased after restart. If I do profile 0, I cannot connect and I can't update my data profile anymore either. Does anyone know how to set the HA on a Sierra Wireless card? | |

| UPDATE - I fiddled around with the HA's for the franklin cdu680 and was able to pick up some speed with the fine tuning. haven't broken the 1M down mark yet, but getting closer. So far pretty pleased with setup, but considering i have been suffering with dialup for years i would be pleased with a string between 2 cans  .
Question: How can i go about finding the sprint tower in my area? I liked to try an external antenna and need to have an idea where the tower is.
BTW - thanks for all the tips & tricks. | |

| Re: Evdo Tweaks and Tuning LOL, yeah I understand that! My problem is that with a Sierra Wireless card there is profile 0 and profile 1. Profile 0 currently has a Primary/Secondary HA and it's NOT one listed above. When I change it to one of those, I cannot connect and I cannot even update the data profile.
If I try and set the HA on profile 1, the settings are lost as soon as the card restarts.
I need someone who has successfully changed their HA with a Sierra Wireless card to tell me how they did it to either to show me how or to confirm that I have a problem with my setup. | |

1 edit | Re: Evdo Tweaks and Tuning said by Jim_in_VA :hj, I am up in Boston this week. Drove all the way from VA to MA and was connected to EVDO the entire way. Never dropped the signal. On changing the HA on the Franklin. Launch connection manager but do not connect to the network. Move your cursor over the plus sign on the left (it will change color slightly),hold down the shift key and type ##DATA. A box will appear asking for a code. This is the 6 digit activation code you must get from Millenicom. Just call their tech support and they will give it to you. After the code is entered a data box will pop up. This is where you enter the HA #'s like the one's found at the top of this post. I found the Kansas City numbers to work best for me. Experiment with different one's to find what is suitable. I did find out my IP address is 70.7.196.49 located in San Jose, CA. I need to get it changed. None of the numbers on the fist post seem to match the one I have.

| ok folks got another one here. I've tried several of the recommended/suggested "tweaks" and each one seemed to improve up & down speeds, but no "WOW" factor yet. getting avg 500kbs dn & 250kbs up,(pings 200ms+/- 50ms). now for the franklin 680 i have it attached to an 8ft lg usb cable in order for me to place near the window for better signal reception. I was thinking of getting a good quality usb cable, (ie., shielded with Au connectors) to see if it would get me a better signal, currently getting around -95dBm, +/-5dBm. (FYI - about 2.4 mi from tower,Non-LOS). | |

| Re: Evdo Tweaks and Tuning A little off-topic, but I don't recommend the gold connectors. I once had a guy at Radio Shack tell me gold was a better conducter than copper. I asked him if he was serious and he said with 100% certainty that it was. I couldn't help but laugh, then left.
Gold is not a better conductor--it's just more resistent to corrosion. You may have already known, but if not I hope I can save you from getting suckered by a Radio Shack guy.

| This is just my own opinion but I don't think that a better quality USB cable would have any effect whatsoever on your signal levels. It could possibly help out your transfer rates but since these modems are not all that fast compared to say a USB hard drive or something that is capable of transferring data much much faster than that, it probably won't be worth it | |

| Re: Evdo Tweaks and Tuning I must say, I really don't understand why you'd have a better signal. The signal isn't transported to the PC over the USB... it ends and starts at the modem. Perhaps the other USB cable just had enough power loss that it couldn't perform at 100%.

It's probably a power issue. The Franklin I just got came with a special USB adapter cord. It has two plugs for the USB ports on the computer and one for the modem. That way power from 2 USB ports powers the modem according to franklin. | |

Its almost as though the tower goes into a low power mode or something and the signal just drops off.
Today my latency is crazy high and I have changed my HA to where I usually get the best performance and then back to default with no improvement. I am using the usb sierra device and have tried using scm and through my topp global router same problem. Anyone have any ideas? I am using a wilson trucker omni with no cable extension.
This is kind of a pain. | |

| I just wanted to add that changing the first HA value in the dialog box (not the primary or secondary) on a CDU-680, it will do nothing for you but deactivate your equipment. It caused me some frustration to get it working again, and also caused someone else to send their brick back to Millenicom. The OP might want to add some stress to their instructions - that folks should only change the primary or secondary HA. | |

Here's my speedtest today. I'm located in Puerto Rico and my HA is KC. The KC HA seems to give me the best results. I suppose the higher ping time is due to the satellite uplink from PR to stateside, but the up/down speeds are quite acceptible.
BTW, my RWIN is 26280. I've tried all sorts of other values, including the 65535 value posted elsewhere, but the one I'm using seems to give the most consistently high results.
The main issue here is staying connected. I'm in the middle of two towers and I have 2, 3 sometimes even 4 active pilots. I'm waiting for 3G to send me a replacement pigtail for the broken one they sent, so I can hookup my panel antenna (CAY1912) and see if isolating to one tower cures the disconnect issue.

| I set up both my Primary & Secondary HA addresses to Roachdale IN, and I am getting good response times. Reading through this topic and some of the topics in the Sprint forum about loosing connections got me to thinking (a dangerous thing in itself)...
Would it be possible/good idea to set the Primary and secondary HA to different cities in the same areas or different areas?
Do HAs act like DNS servers? IF the primary falls off the network then the secondary takes over? If that is the case then it might be better to point to different areas, so for example my primary would be Roachdale but my secondary might be Relay, MD.
The reasoning for this is that if a primary goes out it might have a cascading effect on the surrounding area(s)and by pointing to a secondary HA that is in the opposite direction (but as close as possible)you'd still have connectivity.
Got other questions too but that is enough for now.

The reasoning for this is that if a primary goes out it might have a cascading effect on the surrounding area(s)and by pointing to a secondary HA that is in the opposite direction (but as close as possible)you'd still have connectivity. The answer to that question is YES. I have my franklin set up to use Atlanta's Area 7 Secondary (.77) as my primary, and Kansas City's Area ? Secondary (185.77) as my secondary. I've noticed each time I connect, it will occasionally sync to ATL, and occasionally sync to KC. Not sure what causes the variance, but it just picks one and runs with it.
So the answer is YES, it is possible to pick two different areas... I picked mine based on info I read over regarding the fastest HA's in the evdoforums thread. I figured I'd try one from each of the fastest ones reported, it yes, it works. Now as if its a good thing to do or not, only time will tell. Remind me in about a week and I'll let ya know if I'm still cookin with it.

| To those that travel alot and want to use a HA close to your location you can change the Primary address to 255.255.255.255 and it will locate the nearest HA to your location. Be sure if you do this to define an HA address for the Secondary HA, otherwise you will not be able to communicate if the nearest HA is not working. | |
