So I've managed to tether my phone (Moto RAZR v3xx/Cingular) via USB to my Macbook Pro (C2D/OS X 10.4.8, config. info below).

The catch is that it always takes me two tries to connect successfully. The first try always fails, the second one almost always succeeds. When it fails, all I see in the logs is:

Mar 2 09:56:37 lynx pppd[6782]: pppd 2.4.2 (Apple version 233-13) started by root, uid 501
Mar 2 09:56:38 lynx ccl[6783]: Motorola 3G CID1
Mar 2 09:56:40 lynx pppd[6782]: Connect script failed

Interestingly, I've tried the program launch2net which allows me to connect 100% of the time. While it's realiable and has a nice interface, at $100, it seems a little steep for what I want.

I've also tried to tether via bluetooth, using an otherwise identical configuration. The very first time, I managed to connect, but since then, same configuration always fails to connect with the above error.

Any suggestions are appreciated. Thanks.

Config. info:
MBP C2D 2.16GHZ/OS X 10.4.8

Network settings for "Motorola Phone (RAZRV3xx)":
Account name: ISP@CINGULARGPRS.COM

Telephone Number: isp.cingular

Everything else is default except for the Modem which uses the Motorola 3G CID1 script, downloaded from http://www.taniwha.org.uk/

Thanks, I saw that thread earlier. I've tried the various options mentioned there as well:
Use TCP header compression: off
Send PPP echo packets: off
Enable error correction...: off
Wait for dial tone: off

IPV6 is set to off as well.

So I think I've followed the instructions correctly, though as they're from 2005, I'm not sure if all of the settings are still necessary, or if there are other changes I have to make.

I use WAP@CINGULARGPRS.COM because that's the one Cingular sort of turns a blind eye to despite its "Terms of Use" restrictions. Turn off all of your other Bluetooth devices when you try to tether using BT; I find that the Apple Wireless Mouse can cause flakey connections with my LG CU500.

[mfbernstein]

Thanks again. I'm signed up for the unlimited data plan (that allows tethering), but I tried WAP@CINGULARGPRS.COM as well. No dice. I don't actually have any other Bluetooth devices. Perhaps the problem is my configuration of Bluetooth (which I'm not too familiar with)... Odd thing is, it did work once, so it can't be completely wrong.

Regardless, I'm still puzzled by the USB tether behavior. Why would it fail, and then immediately work afterwards, only to fail if you disconnect and try again?

[f1000]

I'm thinking that maybe you need to increase the lengths of the pauses/timeouts in the modem script. I'm not exactly a whiz at interpreting AT commands, at least not without relearning them, so maybe someone who actively writes scripts can help you here.

Whats your process for tethering your phone via USB? I've been trying to get this and it doesnt seem to work for me.

I am writing this from a laptop connected to the Internet via bluetooth using a Motorola V3xx on the Cingular wireless 3G network. I fumbled and fumbled until I went back to the Cingular website and found a page with everything I needed. I'm assuming that this will work in areas that are not 3G capable as well. Don't pay attention to the bluetooth adapter part. The instructions assume there is no built-in bluetooth capability. Just use the settings and you should be fine.

I have a similar setup - V3xx, PowerBook G4, Cingular - but I'm having a strange issue. I can browse web pages fine, but I cannot download files. If I use the full bandwidth of the link like that, or any high throughput activity (streaming media, etc), the modem disconnects ("hung up unexpectedly" says my Mac) after about 200-800KB of transfer. Is anyone else seeing this activity? I've Googled the daylights out of this and can't find any similar reports.

This only happens over Bluetooth, not USB cable, so that seems to eliminate the network as the problem. Also, my Mac doesn't report that any errors occurred on its end in the log, which would implicate the phone is crashing, but I don't have another computer to test with so I can't be certain of that. I have used my Mac with another phone (a Verizon EVDO phone) successfully over Bluetooth. Any reports of similar activity (or confirmed ability to transfer large files - here's one) would be helpful. Thanks.

MacTad, thanks a bundle for the instructions: very clear and complete. I just tried them, and it worked!

Is there a way to integrate the terminal part into the original modem script though? Manually executing them each time is a bit tiresome... Thanks again!

[MacTad]

Glad I could help, mfbernstein. As for integrating the terminal in the script, I don't know. The directions are from Cingular. However, I've been considering using Automator to automate the entire process. I've never used the program before, but it seems to me that this might be one of the reasons it is included in 10.4.

I have followed the instructions to connect to the Internet with the V3xx, but when I start the connection I get the error message "A crossed connection has be detected. Please check your settings and try again". Has anyone run across this? There was only one page on Apple's site and that was regarding this issue when using the internal modem.

Many thanks.
