T-Mobile GPRS / EDGE GOOGLE FIX - regedit MTU setting

[Squuiid]

For those of you who cannot browse GOOGLE sites using the unlimited T-Mobile GPRS/EDGE plan do the following:

On your WM5 device, use a registry editor and do the following:

Go to HKLM\Comm\Cellular Line\Parms\tcpip
and add a DWORD registry key called MTU with value 1460 (UPDATED)

Open PocketIE/Opera/Netfront and go to any Google page you want!

Oh, and make sure your internet gateway is using:

internet2.voicestream.com

It seems as though the fix is not working for all cities.

I'm actually in New York City, so I guess the MTU values could be different in different areas. Works great on an MTU of 1460 in NYC.

You can try values from 1500 (default) all the way down to 1400.

Trial and error, if it does work for you though, please post the city and MTU value you got it working with.

Goodluck everyone. I have been struggling with this since February and am really pleased I have finally managed to resolve it.

If there are any other New York City T-Mobile users, please confirm the fix.
Thanks.

The following solution worked for me on my T-Mobile MDA. Note: the NdisWan key did not exist, I had to create it from scratch. Before adding the information below into my registry, I was unable to get past the initial google page. Now I can google anything, and use google maps too! And BTW I am in Long Island.

Change the MTU Settings for PPP Connections

Click Start, click Run, type regedit in the Open box, and then click OK.
Locate and then click the following subkey in the registry:
HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Servic es\NdisWan\Parameters
Add a Protocols subkey (if it does not already exist). To do so:
a. On the Edit menu, point to New, and then click Key.

b. Type Protocols, and then press ENTER.

4. Add a 0 (zero) subkey to the Protocols subkey. To do so:

a. Click the Protocols subkey that you created step 3.

b. On the Edit menu, point to New, and then click Key.

c. Type 0 (zero), and then press ENTER.

5. Click the 0 subkey that you created in step 4.

6. On the Edit menu, point to New, and then click DWORD Value.

7. In the Value data box, type ProtocolType, and then click OK.

8. On the Edit menu, click Modify.

9. In the Value data box, type 800, make sure Hexadecimal is selected under Base, and then click OK.

10. On the Edit menu, point to New, and then click DWORD Value.

11. Type PPPProtocolType, and then press ENTER.

12. On the Edit menu, click Modify.

13. In the Value data box, type 21, make sure Hexadecimal is selected under Base, and then click OK.

14. On the Edit menu, point to New, and then click DWORD Value.

15. Type ProtocolMTU, and then press ENTER.

16. On the Edit menu, click Modify.

17. Under Base, click Decimal, type the MTU size that you want in the Value data box, and then click OK.

18. Quit Registry Editor.

19. Restart your computer.

The MTU size that worked with the customer I was talking to was 1350.

This worked PERFECTLY! I'm in NYC as well and 1450 worked. (for what's it worth, that long process also described in this thread DID NOT work for me)

Squiid you are the man I work in NYC and live in NJ works like a charm... it's especially great cause i'vee ben trying to access all my gmail and GFYD accounts and it's been so inconsistent. It works well thus far thanks!

The registry fix for MTU of 1450 seems to be working in Dallas, thanks for the tip.

[boomp311]

ok... so right after I added the editi in the registry it worked right away I was sitting at the starbucks on W35th and 7th. Then I went to a building right down the street and had to google something I couldn't access any google page.

I had great service in the building just no google pages which thought I had fixed. Now I can't access them from anywhere in the city again? the MTU edit is still in my registry.

Any ideas on this? thanks?

This worked for me, PHL market.

It allowed me to get to google.com.

However I still can't access any of the other google sites. (local/maps)

[Squuiid]

Have done some adittional testing, an MTU value of 1460 works best!

1450 sometimes works on all google sites other times not.

1460 seem to work all the time.
Please leave your feedback, and for those that have, thanks.

I´m not with T-Mob but I do have these problem, I tried the values you suggested but doesn´t seem to work. Is there a range of values that I should try?

Here one may find a useful list of values depending of the connection type

by the way, none of these worked for me.

The MTU size that worked with the customer I was talking to was 1350.

I'm using an 8525 with

CE5.2.1622 ( Build 18128.0.4.4 )
ROM 3.62.502.3 ( 10/11/07 )
Radio 1.16.00.00
Protocol Ver: 32.53.7018.01H

( Yes I used pof's SIM/CID Unlocker....way to go pof ! )

Anyway, I've tried adding these keys ( which, by the way, once I reboot the 8525, I lose all BUT the "ProtocolType" entries under the "0" key ), and setting my MTU from 1430 to 1460 as the original author suggested, and I can get past google.com, and it simply dies "Opening" gmail/calendar/maps.

THe funny thing is I'm running Xplode's WM6 ROM for BlueAngel on an older Siemens SX-66, and even though it DOESN'T have any of these entries mentioned, it works....I can go to gmail just fine, even without the registry settings.

Has ANYONE gotten a consistent solution to this ? Is there any particular ROM image someone can recommend to move to that includes fixes for this ?

Thanks.

[marcelol]

I updated the Radio ROM To 1.54.30.10, and it still doesn't work. Even though now, I have 2 "cellular line" entries in the HKLM\COMM section of the registry.

Hi everyone,

I am wondering if any can look over my problem and possibly offer some advice?

I have a problem probably generic to most PDA devices where i can not change the MTU size for the PPP Protocol.

I have made the changes as advised in this thread and neither have worked for me, the MTU is still default 1500.

Changes made are as follows:
"HKLM\Comm\Cellular Line\Parms\tcpip" Set to 1450, MSS is still 1460
"HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Servic es\NdisWan\Parameters\Protocols\0" and also changed \Parameters to \Parms as they all within Registry on WM6 and set ProtocolMTU, PPPProtocolType and ProtocolType as in XP, MTU set to 1450 but the MSS is still 1460.

I am using Windows Mobile 6.

The tool i use on the PDA is the Microsoft Power Toys Analyzer, copy the file to my XP machine and open the netlog0 file with Wireshark and investigate the capture.

The latter of the two keys is how the MTU is changed on a Windows XP machine.

I do know that data cards connected to a PC that use the WWAN protocol for GPRS connection will list a Wireless Network Interface card and for that the MTU would be changed under the network adapter itself, if they are using the PPP Protocol and listed as a Dial Up adapter the the latter key above must be used, all tested and works a treat.

I am imaging that PDA devices must work in the same way.

The devices i am currently using definatly use the PPP Protocol to connect, can anyone advice how this MTU is changed or even advice how to tweak registry to get GPRS to use WWAN, the latter may be impossible for me as i am not a software developer, tweaks i can handle.

Well thanks for looking at my post and i hope someone can point me into the correct direction.

Many Thanks
Martin.
