I have an 8310 that I tethered to an office laptop the other day and have not had a single issue getting configured and connected as a modem. My 8310 is setup with my company email connected to our BES.

Fast forward to tonight at home...

I want to get my 8310 setup on my home laptop which is NOT connected to my company network. I installed Desktop Manager, setup the modem and network connection exactly as I did at work. I have not only double checked the settings but have triple and quadruple checked the settings. I then rebooted the laptop and the 8310, it still didn't work so I removed everything and redid it... same results! :(

Currently I am receiving an Error 692 which means the computer basically isn't seeing the BlackBerry.

Could the problem be that when the Desktop Manager starts up it wants to set the 8310 up as a BIS because my BES isn't available? I keep cancelling that as I can't have the BES settings removed otherwise I'll never get my work email. Am I correct in my thinking that if I were to allow the Desktop Manager to reconfigure my 8310 to BIS that I will be cut off from my BES? What if I were to setup my home email along with my work email on the 8310, could I then have it connect to both a BES and BIS and get this working?

Am I correct in my thinking on the problem?

Thanks.

If your home laptop isn't seeing the BB, that's not realated to the BES/BIS issue.

First thing to check would be to see if when you have your BB tethered, your system actually sees the BB as a modem. If you go into Control Panels and then Modems then pick the modem that was created by tethering process, usually "Standard Modem". Run the Diagnostics and see if the modem that responds is one that identifies itself as the RIM modem.

Until you get that resolved, the BES/BIS issue isn't going to matter.

Out of curosity, does your home laptop have a builtin modem? How does the system distinguish between that one and the one for the BB?

Hope that helps.

In order for me to run the diagnostics and for them to connect I have to start Desktop Manager and make sure that the BB shows it is connected and then it queries the BB without issue. But it still can't connect.

I think I am on the right track with the BB needing to be connected fully to the Desktop Manager otherwise it won't allow me to use it as a modem.

Yes, both of my laptops have built-in modems. It distinguishes between the two types of connections based on how you configure the Network Connection, so long as you tie it into the BlackBerry modem you're good.

Ok, I got this resolved after being on the phone with AT&T for close to 2 hours. Most of the time was spent being on hold.

I have had what was supposed to be the BlackBerry Enterprise Unlimited Service which I had been told allowed unlimited BlackBerry as well as tethering/modem connections. Well, that was when I was with Cingular... AT&T had different types of accounts so it changed.

I had to have my account changed to the following:

BlackBerry Enterprise Unlimited + Tethering for $59.99, the normal price is $74.99 but since I have phone service it gets discounted to the lower price.

Whatever BlackBerry service you have with AT&T you need to make certain you also have the Tethering feature added on.

As soon as my account was reconfigured and I reconnected to my BES I then reconnected my 8310 to my laptop, skipped the BIS "upgrade" and it connected.

HTH and thanks for the help.

Whats curious is that it worked from one machine but not another.

I agree with you completely. AT&T even said it never should have been working in the first place. lol I did confirm that there weren't any charges at least.

I am using 8310 Curve and trying to tether it to a laptop to connect to Internet with Vodafone in UK.

Have v4.3 of Desktop Software and using XP on laptop. I keep getting Error 734 The PPP Link control protocol was terminated and when I query the modem get this

AT+GMM - BlackBerry IP Modem
AT+FCLASS=? - COMMAND NOT SUPPORTED
AT#CLS=? - COMMAND NOT SUPPORTED
AT+GCI? - COMMAND NOT SUPPORTED

Have used the following strings with same 734 error

AT+cgdcont=1,"IP","internet"

+cgdcont=1,"IP","internet"

Have also changed internet in the string to wap.vodafone.net but no different

Can anyone help please.

First thx for helping.

I received a new 8310 Curve. I installed desktop 4.2 SP2, connected the Curve to the laptop, and everything seemed fine. 2 RIM Virtual ports added, with a standard modem. The desktop software and device manager see everything and work fine. However, when I tried to query the modem, I get a "The modem failed to respond". I have tried multiple uninstall/reinstalls, checked hardware control flow settings, the right extra initialization string, etc. Basically everything. This exact same laptop worked perfectly with my Pearl. Any ideas what else to look at? I'm desperate!

Thx again.
