tethered data connectivity troubles

Michael - 16 Mar 2006 19:32 GMT
I've had a Pocket PC configured to connect to the internet via Bluetooth on
a Motorola V557.  This has worked fine for a long time.  This weekend, I
noticed that it was not working and has not worked since.  Nothing has
changed on the phone or Pocket PC, but its like the network is refusing the
connection.  I'm dialing *99# .  I've tried ISP@CINGULARGPRS.COM and
WAP@CINGULARGPRS.COM for usernames (along with blank username, which I had
been using).  I'm using CINGULAR1 for the password.

I've also noticed that data availability has been up and down in my area,
Memphis, which is unusual.  It has been showing up when I have tried to
connect and I am able to connect to Media NET features on the phone when
data is available.  But, the Pocket PC Bluetooth connection fails after
trying to dial *99#.

Is anyone else started having trouble recently?

I'd very much appreciate any suggestions.

Thanks,
Michael

OK.

Perhaps that's the problem.

Then you need to stick to MEdia Net settings on the Pocket PC.

How exactly?  Have you tried dialing other profiles?

MEdia Net with a V551 tethered to a computer over Bluetooth is working fine
for me here in Northern California.

Hi John,

Thanks for your response.

>> Obviously something has changed since you're mucking with your settings.

I've never changed the original connection settings, but created a new
connections on the Pocket PC to try the methods described on the wiki.

> > That doesn't make sense -- the correct username is required.

Confirmed that the username is blank in my old connection that worked for
many months.  Not sure where I found those instructions, but I never had a
problem with it working until the last few days.

I can understand a suspicion that something has changed on my end, but my
wife has identical equipment and settings.  She doesn't know _how_ to change
anything.  Hers stopped working at the same time mine did.  Which also
coincided with GPRS being unavailable for short periods.   My coworkers
reported that their phones were not receiving text messages and showed
incorrect time on the clock over the weekend.  Makes me wonder if they were
working on the network.

> > Perhaps that's the problem.

I would agree, except that when the phone indicator shows GPRS/EDGE
available (most of the time), I am able to get data on the phone itself.
However, the Pocket PC connection still fails.

> How exactly?  Have you tried dialing other profiles?

The Pocket PC connects to the phone via BT and dials *99#.  After several
seconds of waiting, it says the connection failed. I have created other
connections on the Pocket PC with settings described in the Wiki, but none
of them are working.

FWIW, my account has unlimited data.  I believe it is true data, not Media
.NET.

Thanks again,
Michael

Unfortunately, your original settings don't make sense.

My guess is that you don't understand completely what's going on (no offense
intended), because the correct username is almost certainly required, and
there are other inconsistencies in what you've been saying.

Sounds like serious network problems.

Data Connect or MEdia Net?  They are different!  

>However, the Pocket PC connection still fails.

If you have DUN support, it should work the same way.  Have you tried it with
a regular (full Windows) computer?

Is there some sort of logging you can turn on and check.  That might be easier
with a full Windows PC.

Then why did you previously say MEdia Net?!  By "true data" do you mean Data
Connect?  Data Connect Unlimited is at least $60 month!  And is entitled to
support for tethering from Cingular.  Look up the exact feature on your
account on-line.  MEdia Net is also "true data", just different.  And that's
what I'm betting you actually have.

I agree with John, since data availability has been up and down in you
area, that would be the first thing to suspect. Just because you have
the E for Edge icon showing does not guarantee that other network
components are working.

On the other hand, if there have NOT been any network issues in your
area, there is the possibility you are experience what three other users
in my market have experienced. Their "virtual" password (for lack of a
better term) was disabled for excessive data usage (for lack of a better
term to describe using a tethered connection without using the
appropriate data connection plan). Once they had the $59.95/mo unlimited
data plan added to their account, they had to use the following user
name/passwords for the tethered connection:

ISPDA@CINGULARGPRS.COM - CINGUALR1
ISP@CINGULARGPRS.COM - CINGUALR1

WAP@CINGULARGPRS.COM - CINGULAR1  Will not work for them now.

Call Customer Support to try to get to the bottom of your problem.

>Call Customer Support to try to get to the bottom of your problem.

Probably not a good idea, since the OP is probably on a MEdia package, and
Cingular doesn't support tethering of MEdia.

That's just your theory, and it's inconsistent with these facts.  If the
feature had been disabled by Cingular, then the phone browser wouldn't work.
It does reportedly work, so your theory can't be the reason.

My v551, and presumably other devices, do track internal usage separately
from external (tethered) usage.  This could, potentially, be used to block
tethering but allow phone-based MediaNet access.

A test of some blocking, perhaps limiting one to a browser that starts at
the MediaNet home page (as your phone is "required" to do, according to the
user agreement), might be a step along this path.  Maybe just in a test
market, like, say, Atlanta.

I would be perfectly happy with a 5MB per month data plan, maybe even a 1MB
per month plan, if it had rollover.  My usage fluctuates widely, depending
on whether I am travelling or not, using google maps and such.  Other
times, I use very little MediaNet access.  I pay for unlimited because the
unused and wasted MB don't yet approach the cost of the one month I went
into pay-per-use inadvertently.

A more realistic pay-per-use rate might be a good alternative, similar to
the old CSD voice-based rate, maybe voice*slots.

How?  The phone (mobile device) obviously knows the difference, but it's all
the same to the network.  Short of modified firmware (which could easily be
defeated with flashing or by using an unbranded unlocked mobile device),
Cingular could only be able to infer tethered use, and doing so would be
difficult, since most tethered things can also be done with the mobile device
alone (e.g., with a J2ME client like Opera Mini, Google Local, or Email
Viewer).

Cingular could indeed limit (cripple) MEdia to its own WAP site, and possibly
a limited selection of additional WAP pages, but thus far I've seen no
evidence that it's actually doing that, in any market.  Have you?  I would
think that would probably result in a large outcry from untethered users.

For example, when tethered to a mobile device, such things as email and
newsgroups could (can) be accessed over SSL (e.g., using stunnel on a
computer).  In that case it's essentially impossible for Cingular to tell
what's going on.  Tracking the amount of data sent and received is pretty much
it, short of blocking SSL altogether, which (as explained in my prior posting)
might well cause more problems for Cingular than it would solve.

Under 100 MB per month(or pick any reasonable number a power user might
browse from the handset) versus hundreds or even thousands of MB (or any
number someone might pull using it for hours a day as their internet
connection to a computer) would be good clue as to what the user is doing.

Not necessarily -- there are mobile device applications (e.g., Google Local)
that pull a considerable amount of data.  My own mobile device applications
are well over your 100 MB per month.  Then there's the fact that the package
is "unlimited", which makes setting any sort of cap a problem for Cingular.

How would that be a problem for Cingualr?
jay - 20 Mar 2006 16:29 GMT
i think that it would be a problem for cingular if it came down to someone
in court and they had papers showing that the service is in fact
"unlimited,"

I don't think that Cingular would have papers proving otherwise.

btw, I have used, err I mean I know someone who has used almost 3 gigs of
transfer every month for a while now and has have never been flagged as a
tetherer, so none of this probably matters anyway

Tell that to the broadband providers who also provide 'unlimited' service
but do restrict or throttle customers who use more than the average amount
of bandwidth.  They've been doing it for years and NOBODY has been able to
change it.  This is no different.

Wireless ISPs do it all the time, *but they also have a FAP (Fair Access
Policy) in place*. Say if you download more than 500 Meg in a 24 hour
period, you get throttled back to like 24 Kbps for 24 hours.

Hughes satellite aka DirectPC had a FAP in place, but did not publish
the limits. It took a lawsuit to force them to disclose the point at
which you would get "FAPed"

Not true.  For example, DirecWay satellite has an explicit "Fair Use" policy.
Without such an explicit policy, a provider cannot get away with that.  In
Cingular's case it would have to show some violation of its terms of service
(e.g., tethering), which would be difficult at best, as I've shown in my prior
posts.  Other than that it could of course terminate service once the contract
has been completed.  Caveat: I am not a lawyer, and this is not legal advice.

Ain't that the truth.  Of course, you don't know what you truly are, so this

Assuming the person was using it as a tethered modem and someone took
Cingular to court over it, all Cingular would have to do is point out
that tethering is prohibited.

A friend in San Antonio got flagged, but in an inadvertent billing foul
up. He had the unlimited MediaNet that somehow got taken off his account
and data charges started appearing. When he called about it, he was told
 tethering was prohibited and they had him sign up for the $59/mo
unlimited Data Connect add-on. His data charges are still in dispute and
up for review. He might get out of the charges as it was a billing screw up.

Cingular would also have to prove that it had been tethered, which would be
difficult at best (as I've shown previously), and show that such a restriction
is legally enforceable.

In other words, he was dumb enough to admit he was tethering.

>His data charges are still in dispute and

He should definitely be able to get out of all charges over the $60/month
($59.99/month, not $59/month) rate, as per the terms of service (and can
probably get out of anything over $20/month if he is persistent).

Well, after a few mostly useless sessions with Cingular Data Support, I
happened across the answer on the web.

If you dial *99***1# you will need to enter an APN. In Extra string dialup
commands on your PDA you need to add +cgdcont=1,"IP","isp.cingular"

This works with the ISP@CINGULARGPRS.COM   / CINGULAR1  credentials.

I also found that WAP@CINGULARGPRS.COM / CINGULAR1 credentials will work on
*99#  if I use this extra dialing string, but substitute wap.cingular for
isp.cingular .

This took up several hours of my time.  I hope this info is helpful to
others.

If you check, I think you'll find that the needed configuration is the same
for *99***1# as it is for *99# IF profile 1 is set as the default profile --
the ***1 just selects Profile 1.  *99# alone selects the default profile
(which may or may not be 1).

In my Motorola V551, Profile 1 is configured with the proper APN (wap.cingular
for MEdia), and is set as the default Profile, so dialing *99# works with just
the proper username (WAP@CINGULARGPRS.COM) and password (CINGULAR1).

I would guess that *99***1#  does not make any difference from *99#.  I
haven't tried it though.  Since it is working as-is and I have both WAP and
ISP connections set up now, it is useful for me to see it dialing a
different number for each.

I noticed that when I set up a USB connection from a laptop using the
Motorola software, it seems to be using profile 3.  Any idea why the
difference there?

Are you saying there is a place to configure the profiles on the phone?  Or
is this a network / account setting?  Clearly, I was not able to get things
working with just the username and password.  The extra dialing string is
required.  I also confirmed this with a coworker who is using a Bluetooth
Pocket PC and a V551.  His connection fails without the extra dialing
string, but succeeds with it.

Check the profiles (and the default setting) for differences.

Not with my V551.  The modem log verifies that Windows XP DUN isn't sending
any extra commands to the phone.

He may have the same configuration issues.
