Default 8700g hobbled as a modem?

Please Login to Remove!

First off, I am new but I have used the search feature. ;)

Secondly, I've gotten the 8700g working as modem by following the steps in the FAQ here. I've experimented with various adjustments also mentioned in the threads (error compression on/off, ip header compress on/off, connection string, etc).

Having said that, no matter what settings I choose my BB-as-modem speeds are unbearably slow. Bandwidth testing is reporting 40-60kbps down, but in reality there is latency on top of that and it's very slow and nearly useless to me.

Can anyone confirm (or deny) that I am only getting GPRS speeds? The BB itself is clocking in at twice as fast, so it's not my reception or location. I have a feeling either it can't operate as an EDGE modem and/or TMo has somehow hobbled its performance.

Thoughts?

Could it be that it's not a dedicated wireless data card, nor designed with the modem function as it's primary task? Or that it still has to dedicate some of it's bandwith to monitor the phone network? I don't know but I do know that it's definately not going to match an EDGE capable dedicated data card.

Hope this helps.

If your getting 60k then that's above GPRS.

Wirelessly posted (8700g: BlackBerry8700/4.1.0 Profile/MIDP-2.0 Configuration/CLDC-1.1 VendorID/100)

I regularly tether my 8700g as a modem. And I regularly leave the connection active for hours on end. Recently I downloaded a pretty big podcast file using the link, at an average data rate of about 80kbps. I followed the FAQ configuration without changing any recommendations.

Question

Does the display on the BlackBerry say EDGE or GPRS when you are trying to make the connection?

What is the serial port speed set to between the computer and BlackBerry?

I never manually set any modem speed, but Windows reports the connection as 115.2 kbps. Looking at my modem settings, I see that "Maximum port speed" is set to 115200.

BB connectivity indicator remains "EDGE ".

Default Adjust bandwidth speed

I adjusted my speed up to 921 via connection properties.
Here you will open up in the general tab, click the configure button and there will will see a drop down menu allowing you to choose modem speed.
