Broken Modem USB Modem

I'm thinking the modem is going out on my older PowerBook G4. I purchased an Apple USB modem as a replacement. In the list of modems available in System Prefs/Network/Modem, the external USB modem doesn't show up (at least that's what my mom says over the phone). Which modem description should I choose to bypass the internal modem in favor of the new Apple USB modem?
Also, under System Prefs/Network/Network Port Configurations it only has the option of 'Internal modem,' the USB one doesn't show up in that list, is that an issue?
Thanks

Apple USB Modem: Frequently asked questions (FAQ)
What Macintosh computers are compatible with the Apple USB modem?
You can use an Apple USB modem with any Mac computer capable of running Mac OS X 10.4.3 or later. You MUST have Mac OS X 10.4.3 or later installed in order to use this modem. If you Macintosh is running an earlier version of Mac OS X 10.4, upgrade your computer's operating system using Apple Downloads or using Automatic Software Update.
Can I use the Apple USB modem if my Macintosh already has an internal modem?
Yes, but you can only use one modem at a time. Make sure you've selected External Modem in the Internet Connect application if you want to use your Apple USB modem instead of your computer's internal modem. The Apple USB modem's preferences can be seen in the Network pane of System Preferences. From the Show menu, select External Modem.

I have acquired a new modem usb modem for my computer which gets me on the internet fine but when I try to load a weg page in Mozilla it tries but always comes up with the error that the connection has timed out. Any Ideas? Thanks

It seems the browser will not let me connect even though the internet is accessed.

Carmell-
When I've had a similar problem, it was because I was accessing the iTunes store from a device I hadn't used before, such as when I upgraded from an iPad 1 to the iPad 2. It was a little confusing to me until I figured it out.
All I had to do was use the ID of my existing account and play along with the iTunes store. As I recall, it asked for my password twice, and the security code from the back of my credit card. After that, downloads proceeded as before.

External USB Modem fax not working under 10.5.8

I upgraded my Mac Mini home office server (print, fax, backup) to 10.5.8 and now it appears that faxing is completely broken (or maybe the USB modem driver.)
I've verified that this is broken on another system.
After booting, the following is seen in the fax log:

Anybody else seeing this?

This solution is a "workaround" and will not affect in any problems, like I saw that they will happen after:
1.) Removing and changing "IOSerialFamily.kext" : ("The system extension '/System/Library/Extensions/IOSerialFamily.kext' was installed improperly and cannot be used....")
2.) or go back to OS 10.5.5... (latest security-updates not included)
Go to your System-Prefs -> Printing and Faxing
chose the Fax-Modem -> Options
1.) to receive faxes: choose "receive faxes on this computer"
2.) to send faxes: choose not to "receive faxes on this computer",
plug your modem out, wait 5 seconds and plug it in.
Now you can send faxes, but not receive,
before you choose "receive faxes on this computer" again.
To send, you have to start with 2.) again...
It's strange for a mac, but better than 10.5.5 or a corrupted system...

Apple USB Modem rarely connects via PPP

Greetings from Antarctica. My employer offers me dialup internet from my dorm room here in Antarctica. Using my Apple USB external modem, V.92 (error correction and compression in modem enabled) and all the correct username/password items, I am able to connect to the local dialup network maybe one time in ten.
The modem gets a dial tone, dials, goes through the concert of tones, the tones disappear just like when a connection is made, but only about once in every ten tries will it actually establish a connection. The other times it will sit there saying "Connecting" until eventually it times out and disconnects the phone line. I have tried using v.90 and v.92, with and without error correction and compression in modem. No difference.
The PPP configuration is to send PPP echo packets, verbose logging is off, Terminal script is none, the box is checked to use TCP header compression.
I am using a Santa Rosa MacBook with 10.5.5, 2 GB RAM. If there is a log file somewhere that would help someone troubleshoot this with me, please give me specifics on where I might find it. If you want me to try and connect with the Terminal window instead, then I will need very specific instructions.
Thanks from McMurdo Station, Antarctica.

I'm not positive here as it could be a hardware failure of my usb modem, but leopard seems to have broken this device for my G5 iMac. Even in Tiger this modem was never as good as the built in ones on the G4 models and would be buggy sometimes and not as fast as the internal G4s. I had wondered if it would work on intel versions with Leopard better, but your experience isn't a good sign.
My solution was to use a G4 mini using it's internal modem and internet sharing via airport which worked well and gave me more freedom on my other laptops as well, though it be at the slow speed of dialup. I would imagine a G5 PowerMac would also work with this modem especially if running Tiger. If this was an early Macbook, it might also have shipped with Tiger, but no idea how this would play out with the Intels vs PPC.
Not sure how you get phone service in Antarctica but I'm guessing there is some sort of satellite device involved. Is anyone else having trouble connecting with modems through the setup? I know PPP is not well supported in certain compression modes such as Voip, but I would imagine if you had voip broadband would be available.
Bottom line seems to be the G4s are gold if you need dialup service. Best of luck!

3g usb modem does not work on Lion?

I have had a 3g usb modem for almost two years now, it worked fine on Snow Leopard but does not pick up any connection to any cell tower after my upgrade to Lion. Any suggestions?

Thank you 'etresoft'. With minimal information from me you have provided a fix to the problem. Although, the cost at 49.5 euros per computer is a bit steep. I think I will just buy a later spec modem at $A79 and be able to use it on all my computers. Regards from iadoreapples

Connection Speed reading for external USB Modem ????

In previous versions of the Mac OS, I've been able to see a readout of my connection speed achieved with a dial-up modem and telephone line (e.g. 28 kbps, 33 kbps, 50 kbps etc etc) but under this latest 10.5 Version of OS X I can't see this speed in the networking software that controls my Apple USB modem.
Has this feature been dropped with 10.5 ?
If not, how do I see the speed. It would be very helpful to see it as I sometimes travel to some pretty remote areas where phone lines are poor - so if you know the actual connect speed you have a good idea of what sort of size of downloads to attempt and not to attempt while on-line.
I can see such parameters as my time connected and IP address assigned by the ISP, but no connect speed.

I realize the speed that used to be shown was the initial speed the two modems involved, mine and the ISP's, negotiated to establish the connection and I also realize that is not the actual download speed.
But it's still helpful to know that initial speed because it is a rough indicator of line quality ands gives one an idea of how rapidly he will be able to communicate - clearly there will be a significant difference for the better in performance for the online session if one can achieve a connect speed of, say 50k, as opposewd to 28k or less on a poorer line.

Using cell phone as a 3G USB modem for Leopard

Hi All,
I just get an MacBook Pro the last week, I was happy with the UI of the OS at first sight, but when come to the setting of the network, I am really frustrated.
I get a SE P1i cell phone, I would like to use it as a usb modem for my MAC so that I can have 3G internet connection when on the road. But the problem is that, I can't connect it to my MAC at all!
Leopard can regonize my phone but it seems that none of the modem script(including the SONY ERICSSON script pre-installed) work for my phone. when I checked in the activity log, I see that the result of running every modem scripts are
"CCLExit: -6019 (Modem error, modem not responding.)"
I guess it should not be the problem of my phone as I try using SE K800i, the same result...
although I know that I can use the bluetooth rather the USB cable to connect them together, I would prefer USB cable as it is faster and more secure.
anyway, any help would be appreciated.

detailed instructions:

AT Commands sent to USB Modem

Hi,
I am trying to send AT commands to a USB modem using VC++. I found the code below online and have tried using it. I do not get any errors but it doesn't appear to be working.
I used Putty to set AT+CMGF= 0. However after I run this code, when I check the value of AT+CMGF it is still 0, so although no error is being thrown up, it doesn't seem to be sending correctly.
Any help would be great thanks.
#include <iostream>
#include <Windows.h>
#include <string.h>
using std::string;
int main() {
std::string data = "AT+CMGF=1";
DCB dcb;
DWORD byteswritten;
HANDLE hPort = CreateFile(
"COM3", //"\\\\.\\COM10"
GENERIC_WRITE | GENERIC_READ,
FILE_SHARE_READ| FILE_SHARE_WRITE,
NULL,
OPEN_EXISTING,
0,
NULL
DWORD dwerror = GetLastError();
if (GetCommState(hPort,&dcb) == 0) {
return false; }
dcb.BaudRate = CBR_9600; //9600 Baud
dcb.ByteSize = 8; //8 data bits
dcb.Parity = NOPARITY; //no parity
dcb.StopBits = ONESTOPBIT; //1 stop
if (!SetCommState(hPort,&dcb))
return false;
bool retVal = WriteFile(hPort,&data,200,&byteswritten,NULL);
dwerror = GetLastError();
CloseHandle(hPort); //close the handle
return retVal;

SOLVED: just needed to add \r\n after my commands
Okay, not solved! The first command, setting CMGF=1 works, nothing else seems to go through though. i.e. if CMGF is 0 and i run this code setting it to 1, it changes to 1 when I check the value in putty.
I'm not sure if im doing something wrong in the way I send the CMGS and text message commands.
No errors come up...but the text message isn't sent. I send the CMGF and CMGS commands followed by a carriage return and the text message content followed by the SUB (CTRL+Z). doesn't seem to work. If I try reading the serial port using ReadFile() it
just hangs without setting a timeout. Any help would be appreciated.

USB modem and Internet Sharing causes system to hang.

First my setup. I have a Mac mini (early 2009) running 10.7.2 connected to the Internet using a Sony Ericsson W910 as a USB modem. I am using Internet sharing via Ethernet to a 1st generation (n) AirPort Extreme to give Wi-Fi to other devices (iPhone, Xbox 360, PS3 etc).
Now the problem: When Internet Sharing is on regardless of what interfaces are used (Ethernet, Wi-Fi, Bluetooth PAN etc) eventually—that word is key—my system will hang. Internet will be unavailable to every device and my Mac itself (but they will still be connected to Wi-Fi) and any app that is running willbeachball. Any app I launch—or try to—will also beachball. I've tried leaving it to see if it will resolve itself —even overnight—but it always requires a hard reset.
The eventually part. I haven't figured out what causes this but I have an idea which I'll explain later. The times this happens is totally random. It has gone days with no problems and other times has happened minutes apart. Usually it's about every 12-24 hours.
It's definitely Internet Sharing which is causing this because when I turn it off I don't have any problems. I've tried every configuration. Only sharing via my mini's Wi-Fi or Ethernet, leaving the AirPort out etc. As soon as I turn on Internet Sharing I've started a countdown to a hang.
On inspecting the Console the last messages before a hang without fail are always:
12/12/2011 06:31:07.000 kernel: 80 80 AppleUSBCDCECMData: getOutputBuffer - Output buffer pool empty
12/12/2011 06:31:07.000 kernel: 80 66 AppleUSBCDCECMData: USBTransmitPacket - Output buffer unavailable
12/12/2011 06:58:58.312 com.apple.usbmuxd: _handle_timer Fish out of water!!!
Repeated hundreds of times. Quick Googling indicates that AppleUSBCDCECMData is a USB driver. Apparently I have version 4.1.15 which appears to be the latest.
I'm aware this is a rare configuration but I believe it affects every USB not just this particular phone.
Is anybody else experiencing this or knows a way to fix it?
Thanks.

Thanks Barry.
The hub is on its way to the manufacturer for after sales service...
But the issue with AirPort remains the same, even after resetting SMC.
Some clarification:
* It happens just after computer wakes up from sleep. Restarting solves the problem and the issue doesn't arise until computer goes standby again.
* The whole WiFi card becomes unresponsive. It is not only the Turn Off button, but the whole functionality is stopped. The card can not be activated/deactivated and it doesn't connect to any network. If it is used for internet sharing, clients are unable to connect.

Hello, All!

After upgrading to Yosemite, MF 820 ZTE Telenor USB modem does not start, system slow down dramatically / Macbook Pro Retina late 2012/. Also Thunderbolt plug in for Ethernet make the same ! Any idea ?

After upgrading to Yosemite, If i plug in my Zte MF 820 LTE modem into my Macbook Pro USB socket or a Thunderbolt USB Ethernet converter/ into my Notebook, it slow down dramatically the system, unusable, need to reboot and unplug the USB moderm or Thunderbolt interface. So it does work only without any plug in device..!?
Any idea ?

Can i connect my ipod touch to internet, via a laptop that is connected to the net by a USB modem/dongle

I have an i pod touch, which i use to facetime friends abroad when i am at home in the uk. I work on a ship and we have very limited broadband and we are not permitted to stream through company PC's. When we are in port what i would like to do is buy a USB modem/dongle (locally, as of now i am in indonesia) for my laptop, and connect to the net using that. Is it possible to make the laptop a wfi hot spot and then connect my touch so i can facetime.
Is it technically doable?
How much data does facetime use, and would it be an expensive way to do it?

Yes. Google for
setup window 7 (or the OS you have) as wofo hotspot
See:
http://www.geeksugar.com/How-Much-Data-Does-iPhone-4S-FaceTime-Use-23562212
for comparison, according to one test of an iPhone 4 FaceTime call, about 3MB of data were used per minute over 3G service. Using this rule, a one-hour FaceTime phone call would use a scant 0.175GB of data.

Unlimited Data Plan on USB Modem

Hello, I'm new to forum and I apologize if this has already been discussed but I haven't seen my particular situation anywhere;
I have a 3G USB modem on the much talked about unlimited data plan. What I have is a month-by-month unlimited plan which is a completely separate entity from my cellphone contracts. I've had this unlimited plan since 2005. (Interestingly, it doesn't seem to me that my usage is being throttled at all, even with heavy usage.) Has anyone heard any news in particular regardingun those of us who still have an unlimited data USB modem plan? Thank you!

I'm definitely aware of this. The beauty is, my 3G modem is quite fast; I can stream Netflix, Hulu and Amazon with almost no hits or interruption of playback. Plus, I had the foresight (I hope!) to buy a backup 3G modem of the same model in case mine gives out or breaks. I'm just hoping that in my case, the grandfathering stays in effect; everything I've seen regarding the elimination of the unlimited data option refers to the phone version of the unlimited data plan, but nothing regarding the USB modem version. Thank you, Ann!

USB Modem no longer working on MacBook

I have been using my Virgin Broadband (Huawei E169) USB modem with my MacBook for the last twelve months. Apart from a huge hiccup when I upgraded to Snow Leopard it has worked flawlessly. Recently I had to restore my MacBook from my Time Capsule as it refused to boot up, and since then I've not been able to use my USB wireless modem. It works fine on my iMac and on my Son's PC Dell Laptop.
When I try to connect, I either get a message that says 'unable to connect to PPP server' or I the 'auto open' closes immediately and I get a huge error report. I have copied the report if anyone is interested, I'll include it on a future post.
I've rung my ISP and Apple Care and have had no success. I've tried a friend's USB modem, and was unable to get it to connect, I also tried mine on her MacBook and got the same errors as on my MacBook.
At this point, I have also checked that I have the latest Mobile Connect and the latest firmware, and have compared files with those on my iMac, and I cannot find the discrepancy. I still don't know whether my MacBook is at fault of the USB device itself. I am loathe to buy a new USB modem, until I know for sure. I don't know what to try next though.
Thank you.

The irony of this problem is that I solved it using a post from here which I'd copied from Whirlpool last year. I'd gone through every solution taht I could find, several times over an in the end used this one which worked perfectly. It was actually my last resort, I'd run out of options. Thought I'd best post back here, just in case someone else has an issue.
This post was found @ www.whirlpoo.net.au by Designed. The OP posted this solution
Thought this was important and needed to be posted here too. I'm up and running again, and very very happy
The solution I found to work is :
1. Open up Terminal.
2. Become root using sudo -i (using your user account password when prompted)
3. Paste the following command in: echo "refuse-chap\nrefuse-mschap\nrefuse-mschap-v2" >> /etc/ppp/options
Next Step
Plug in the device, when the disk image mounts, right click on the app and choose 'show package contents'
Navigate through contents -> resources -> and run the MobileConnect_DrvApp.pkg
Reboot
Then in system prefs -> network
you will see HUAWEI Mobile (not connected)
Add the following settings
telephone number : *99#
account name : VirginBroadBand
password : VirginBroadBand
TICKED Show Modem status in menu bar
I didn't have to change any advanced settings, but to confim them
(In Advanaced Settings)
Vendor : Generic
Model : Dialup Device
TICKED Enable Error correction and comptession in modem
Dial Mode: Wait for dial tone before dialing
Dialing TICKED Tone
Sound TICKED On
Now I connect via the icon in the status menu
