Tutorial: USB DUN with "Wireless Modem" app on HTC Mogul

[MrBogard]

I need help. I'm following this process step by step on my mogul, and I've hit a snag...

Setting PAM (Phone As Modem) as the default dial-up connection

1. Go to Start->Settings->"Connections" tab
2. Select the "Connections" applet
3. On the "Tasks" tab, select "Manage existing connections"
4. On the "Modem" tab, make sure the "Phone as Modem" radio button is selected
5. Press "OK" to save your changes

I don't have "Phone as a Modem" listed under existing connections--and I've completed the previous steps. Help?

I believe if your connection shows up as "Sprint PCS" with #777 then you wouldn't need to do this step. I think, but not sure, that the "phone as modem" shows up on the old PPC-6700. You shouldnt have to do this, just follow the rest of the instructions and you should be fine.

Thanks! Great guide btw--a ppcgeeks classic

This was an excellent post, the only suggestion I have would be to reorganize so that the order of steps in the summary matches the detailed order.

I got this working without any problems, except: I don't have Phone as Modem as an option so I had to use Sprint PCS. I was unable to remove the "Extension" from the registry although thats not related. It also seems to always want to install drivers (on my XP box) whenever I try to connect even though I already installed the drivers, and it works.

The bad news is, its dog slow. The fastest upload speed I've gotten is a little under 100kbs, and the fastest download speed is a little over 300kbps, with an average speed of under 200. Latency varies from about 90 to 300 ms. The phone is as far from the computer as the USB cable will allow and I've tried multiple positions. The USB connection claims to be at 115.2kbps, I can adjust this up to 900kbps but it doesnt' seem to help.

Anyone have any suggestions?

I would check and see if your REV A settings is set to "enabled" You do this by using your dialer and pressing ##778# and enter your unlock code. If its enabled, set it to Disabled and try your connection once again. Hope this helps. Im sorry Im being vague on these instructions, its just that Im going by memory!!


EDIT ** I went and tried it. Press Dialer. Enter ##778# . click edit. Enter MSL Unlock code. Click on "View Info" and select Data Parameters. Make Sure Rev. A is Disabled. Follow Prompts.

to further clarify twin's post:

the setting should actually say "disable" (this means it's enabled)
if it says "enable" then change it to say "disable"

Open up your dialer, and dial in ##3282#

doesn't work for telus customers....
How do we do this step for the p4000 on the telus service?

It seems Sprint/HTC neglected to give us the necessary files to get the "Wireless Modem" (from the good old pre Windows Mobile 6 days) application working. This is a howto on getting "Wireless Modem" setup and running. I've attached the missing files needed at the bottom of this post.


Tested with:

HTC Mogul running original v2.08 Windows Mobile 6 ROM with Windows XP Pro SP2 (32-bit), and Vista Ultimate Edition (32-bit)


Why is this better than other methods?:

You may ask what the purpose of this method is when you may already have a working solution such as Internet Sharing, PDANet, or USBModem? Good question, it's:

Better than PDANet because:

• It's free
• Doesn't rely on ActiveSync
• Can be shared. Since "Wireless Modem" works through a dial-up adapter, on Windows XP/Vista machines it can be shared with other clients via ICS (Internet Connection Sharing). For instance I've connected via my laptop, and shared that connection via a crossover network cable from my laptop to an XBox 360, to let the XBox 360 access the Internet!

Better than USBModem because :

• It's free (Wireless Modem's behavior is pretty much identical to USBModem)

Better than the "Internet Sharing" application (included with WM5 AKU3+) because:

• It's not NAT'ed, you get a public IP with "Wireless Modem". NAT'ed connections are problematic with some games and applications, such as certain VPNs.
• Since it's not NAT'ed there's less communication overhead, resulting in a slightly better latency, and faster transfer speed.

Setup Summary

1. Install the Dial-up Networking through Bluetooth Under WM5 AKU3/WM6 Hack
2. Enable PAM (Phone as Modem), and set it as the default dial-up connection
3. Apply registry changes to (hopefully) disable NAI (tethering) detection
4. Setup a dial-up connection on your client (eg. laptop) device
5. Decompress the attached files and place them in the proper folders
6. Run the "Wireless Modem" app, and start it sharing via USB
7. Connect your device via USB cable to your computer
8. Dial-Up to the Internet and enjoy!

Installing the Dial-up Networking Through Bluetooth Under WM5 AKU3 / WM6 Hack

1. From the Bluetooth DialUp Access folder in the attached .zip file, install WM6_BT_DUN.cab into main memory on your device.
2. After installation, soft reset your device

Enabling PAM (Phone as Modem) Connection

1. You must first have the MSL number for your phone. The MSL unlock code is used for programming your phone yourself, and is unique for every phone. You can retrieve the MSL for your phone by using the GetSPC application. It's essentially a keygen that calculates what the MSL should be from the hexadecimal ESN (case-sensitive). You can download it from HERE. Otherwise you can call Sprint technical support, tell them you're a developer, and you need the MSL number for your phone.
2. Open up your dialer, and dial in ##3282#
3. A window should open, select Edit
4. Enter in your MSL from step 1, and press the OK button (left softkey)
5. Select the line that has the value MIP_Mode under the Item column
6. Press the Menu button (right softkey) and choose Edit
7. Change the value from from Mobile IP Only to Mobile IP Preferred
8. Press the OK button (left softkey) and soft reset when it tells you to.

Setting PAM (Phone As Modem) as the default dial-up connection

1. Go to Start->Settings->"Connections" tab
2. Select the "Connections" applet
3. On the "Tasks" tab, select "Manage existing connections"
4. On the "Modem" tab, make sure the "Phone as Modem" radio button is selected
5. Press "OK" to save your changes

Disabling NAI/Tethering Detection (hopefully)
Using a registry editor, navigate to the "HKEY_LOCAL_MACHINE\Software\OEM\WModem" key, and set the "CheckProfile", "Multi-NAI" and "WModemDUN" DWORDS to a decimal value of "0". Remember to soft reset for the changes to take effect.

Note:
The following note does relate to getting the "Wireless Modem" application, but might of interest to those using the "Internet Sharing" application. It seems Sprint is up to shenanigans in regards to tethering for SERO users. Those of you running Sprint ROMs should navigate to the following registry key "HKEY_LOCAL_MACHINE\Comm\InternetSharing" and delete the string value named "Extension". This will allow you to connect to the Internet via the "Internet Sharing" app without the dreaded error 67/authentication errors. Previous to this fix, Mogul SERO users would have to connect to the Internet via another method (such as starting Internet Explorer first) before pressing the Connect button in the the Internet Sharing application.

For the lazy, I've created two Mortscripts (included in the attached .zip file), that apply ("MogulTetherFix.mscr") and, check ("CheckMogulTetherFix.mscr"), that the proper registry entries have been made (both for "Wireless Modem" and "Internet Sharing"). To use these scripts you must first download, and install MortScript from HERE or HERE.


Installing the missing files:

From the attached .zip file, copy the following files:

Wireless Modem.lnk
- Description: Shortcut to Wireless Modem application (Points to "\Windows\WModem.exe" /LAUNCH)
- Place in \Windows\Start Menu\Programs folder on your device

WModem.exe
- Description: The actual "Wireless Modem" application
- Place in \Windows folder on your device (v2.08 Mogul ROM already has this file).

WModem.exe.0409.mui
- Description: English language resources file needed by WModem.exe
- Place in \Windows folder on your device (was missing from v2.08 Mogul ROM).

Im not sure what you mean, but does the menu appear stating to view, edit, etcc.?? Then asks for the unlock code? or nothing happens after entering ##3282#?? When you stated that it doesn't work, what do you mean? Im using Sprint, so Im not familiar with telus services, but I would think you can get the menu to appear.

You can also look at TalynOne's post #20 on this thread. He has a workaround for bypassing the EPST code. Hope that gets you to it.

I combine some of all of the info I've found...

Did the three reg tricks found in the first post, as well as deleting the 'Extension' reg key from LOCAL_MACHINE\Comm\InternetSharing.

Seems to work just fine so far, thanks!

I've been using the Wmodem program for a couple weeks and the setup, etc...listed here worked great with no problems.

My problem is that my Mogul keeps using the painfully slow 1x connection in areas where EVDO is available.

For example, I live near an interstate and always get EVDO here. If I drive out into the boonies and get a 1x connection and then come back here, it's still on 1x.

There are two issues at hand here:
1.) The phone is not using the best available service
2.) If I shutdown Wmodem, the 1x connection immediately turns back to EVDO.

How can I correct this problem? I don't mind if it uses a 1x connection if that's all there is, but there's definitely something else going on here.
