U727 - Factory reset speed things up.

First, let me say you probably do not want to try this at home, as you may brick your modem.

After the GPS feature stopped working on my U727, I called Sprint for a dose of really lousy tech support. where in the end, after getting hung up on, two techs that didnt have a clue, and was finally told they do not support the GPS features. I took matters into my own hands.

I copied down all the settings from all the screens (including the ##data screen), and did a factory reset via the ##RTN command.

Afterwards, I filled in what I could, and the card would not dial out and re-authorize. I added a second internet connection, tried again, and it came right up this time, initialized/authorized though the secondary internet connection. So far so good Smile

The GPS came right up, and started working again. I did a few speed test and noticed a huge improvement.

The factory reset did not change the firmware, nor did it change the PRL. It did set my home agent back to Kansas City (a home agent I have had a lot of trouble getting good speed from in the recent past).

Anyway, it's been three days now, I have been running lots of speed tests, and the performance has stayed top notch. I have a marked improvement in speed throughout both the day and night.

So I am wondering, besides getting the GPS to start back up, what could have changed to make such a difference?

While before, I was getting Rev0 speeds of 1500 to 2200 mbs down quite often in the evenings, now I am getting it most all of the time.

All the settings are the same. The change happened instantly upon the reset, and I seriously doubt Sprint upgraded the tower at the same exact moment.

So why the improvement?

Ideas?

Joe,

A couple of questions Joe on your resetting the modem.

What data screens are you refering to that you copied down?
The ##RTN command, how did you generate it and send it to the Modem?

Kastly what GPS application are you using?

Thanks

Ron

Restarting like that reactivates the device on Sprint's end. Over time, it will probably slow down again, mine always does after I reactivate the device.

The ##RTN resets the user activation only The problm was with the provider system.
