maybe I missed something with tmobile GPRS

Despite tmobile saying that the 5.99 restricted dataplan will not work on the Wizard even though I've had it working since the day I got the phone, I stumbled upon something that seems strange henceforth I think I'm missing something with this GPRS stuff:
Here is what I've found recently:
Use "tmobile web on wizard"
set proxy to 216.155.165.50 on port 8080
set T-mobile data to dial wap.voicestream.com
This will allow pretty much complete web browsing, except for FTP and Remote desktop.
I'm sure everyone on this form knows this by now.
Though I was playing around with the bluetooth modem/USB modem capabilities of the device.
In the connection settings for the number dialed you use *99# change a few setting in windows and then you have your GPRS connection on your PC. Change firefox to use 216.155.165.50:8080 for the proxy good to go.
Though friday I discovered something, the internet was down at my house and I needed get online, seeing that I know I can use my phone as a internet adaptor I paired the bluetooth and created a dialup connection using bluetooth number dialed *99#. I was on the web but this time it was different, I no longer had to put in the proxy into my browser, RDP worked, VNC works, it is like I had a full (somewhat slow) connection. No restrictions except FTP access.
I find this great, I can do pretty much everything I could normally but what is different? Did tmobile screw up?, is it using my minutes instead? Is there something about the networking when used as a modem I do not understand?
Though I am not able to replicate this level of non-restriction on my phone itself (which would be really nice), when is the other foot going to drop and I get really large phone bill from tmobile?

I don't think you're going to get hammered with a big data bill but those ports will not stay open forever. Check out threads in the t-mo forums on hofo from the last few days. Everyone had connection troubles and now it looks like the ports are closed again on the t-zones apn. Prior to this I was able to tether, stream, run bit-torrent(slowly), d/l large files, etc. Now everyone is reporting, myself included, that we HAVE to use the proxy again and the ports are closed up now. Some people, mostly east coast, are reporting no problems yet. But from Cali to Illinois it looks like the free ride is over. And I'm finding it hard to open my wallet and fork out $20/mo for what I was paying $6/mo for last week. Especially when seeing my bro down the hall from me paying Cingular $30/mo and getting 900+kbps down and 384 kbps up. Speeds are way down on the t-zones apn now too. Have been getting 190-220kbps now getting around 70, if I'm lucky. Way to go T-Mo, I stab at thy heart.

I'm really pissed now because I used to be able to access Citrix through the proxy but it is not letting me anymore.

internet sharing htc 8525 question

I already pay 4 an unlimited internet plan through cingular. I downloaded the wmwifirouter to my phone. I was wondering if I used this apllication to share my internet would there be additional charges.

no the operator would not even know all net activity was not don on the phone itself
if you want more info about how network routing works this is ok reading

I would be careful if you are thinking about using it to connect you laptop. Even though you have an unlimited download regular web pages takes up significantly more data. Depending on how much you are downloading they could eventually suspend you account and/or up your rate. Casual use shouldn't be an issue.

SGS - internet connecting pc problems

Hi,
I live in Australia. I bought a SGS from UK. It has nothing changed in firmware its the same as it comes from the box. (just a few games and apps installed from the android market).
My problem is when I connect the SGS to my laptop through the USB cable and I chose "PC INTERNET" I get a connection but i get a lot of drop outs, I would say being honestly every 5 minutes my connection drops. I live right in the city and my phone has good reception so its not the reception.
I haven't tried teethering (i dont wanna teether coz mobile plans says, NO teethering).
What can I do to fix the drop out connection problem.

if you are using your internet via the LAPTOP over the USB cable, then you need to figure out WHY your LAPTOP is not connecting properly to the Internet.

it takes about 1 min to connect and when it connects i choose HOME connetion. than it works good for 5 mins and it drops out and reconnects itself.

Correct me if I've read your post incorrectly but isn't what you're doing tethering?
From Wikipedia: "Tethering is the use of a mobile device such as a mobile phone to supply Internet access for another device which is otherwise unconnected, using the mobile device as a modem. This can be done through Bluetooth wireless technology, Portable Wi-Fi hotspots, or cables (such as USB)."

well yes and no...
it is teethering but carriers cant prove that.
however
if i do select teether on my phone it says something like this option will use black hole date or something (from my understanding is that it will use different data to my free date) so i choose to try the cable connect than select interent connection.
anyways the problem is still there... has anyone got any solutions or give me some ideas?
thanks

are you trying to use your phone as a modem or not?
if you are, then we can help you there are many ways to do it.
but if you are doing the opposite, using your laptop internet, for your phone to access internet (which doesn't make any sense at all) then we can't help you as it's a laptop problem.

im trying to use my phone as a modem but in a way without carriers finding out im actually using my phone to teether.
my problem is that my connection keeps droping every 5 minutes for 10-30sec.

I use my Galaxy as a modem and I had nothing but hassle when connecting using the cable. I found out its far better to go into settings then wireless settings then switch mobile AP on. Your phone sends the connection over wifi to the pc and gives me no hassle at all.
I reckon the only way your service provider would know is by looking at how much data you use so just be careful and you should be fine. Or find out what your monthly limit is and put a data counter on the phone, I use Netcounter, its free and simple but gives the info you need like daily, weekly and monthly usage

yup, the wireless method is by far the easiest one, and best of all it is build in!
as for your cell phone provider finding out, regardless of what you do, they don't care, they only check how much data you used up, and charge you that amount

well im on 1gb per month. Plenty of data there.
I tried another method today: turn bluetooth on and connect through bluetooth and that seem to works perfectly. I was online for 3 hours without dropping once.
Now I`m wondering why was it dropping with the cable connected? And not even once through bluetooth!

I understand your Problem, but at time i reading your last Post i have an question.
I understand your Posts that you dont use Wireless thether becouse your Carrier dont Allow Laptops to Acces Wireless conections right?
But it makes no difference if you use the cable or a wireless conection to thether your Internet. If you surf under the radar you dont getting into troubles. And there is no blackhole Data when you tether wireless. Its a gprs, edeg, 3g or umts Connection and your Phone manage this automaticly. So now comes my question. Why you dont use the build in wireless tether function which is the fastest and easiest way to connect. You dont need the phone directly near the laptop, you can give it to the point of best data connection, okay and a powerstrip for the akku. But its much faster then the Bluetooth connection, becouse of wlan.

"And there is no blackhole Data when you teether wireless"
From now on I will use the AP to connect. I thought the carriers (OPTUS) might find out. But since they can't find out than this is the best option. Thanks for confirming they cant find out weather I connected my laptop or just used the date from my phone.

This remind my at the old days where you share your internet connection thru a soho rooter or just another pc with 2 network cards built in. In these early days the Provider says its forbidden to use the connection for more pcs than one. But in fact they never could meassure this and no one ever gets an letter from them or an contract decline/service interuption. The truth is, that there was a kind of law process against them and now the isp's is forbidden to limit the usage of your internet connection to only one device. So that means not that you get unlimited numbers of ip adresses, but you can NAT as much devices you want. Now you get from every ISP a Preconfigured router if you like.
And the same will hapen over a pariod of time to the wireless providers as well. Its your connection so you can use them the way u like it. Its already happend here, you can buy umts router for your home.
Where i live there is no question like this. Just do it. But maybe its becouse of our mentalogiy. If somone says no the typical austrian will do it anyway and gives no dime to what others say. If no one forbid you something then its allready allowed to do. ;-)
Greetings to Australia (the country with the kangaroos) like we here in Austria say. lol

[Q] Any solution to keep IP from changing?

I know that this thread will probably be over in approximately 3 posts, but I figured this was the place to ask to get a good answer.
I am part of staff for a site that uses my IP to enable staff functions. These functions are set to the IP I'm on. However, it never works considering my IP constantly changes when I'm on the T-Mobile network, and I do not have access to wifi. Is there any possible way at all, to be able to make this work, either from my N1, or on my PC using my N1 as a 3G hotspot? I'm not all that knowledgeable about networking, but I'm thinking there has to be some possible way to make this work somehow. Maybe I'm wrong and it is one of the impossible things to do on a cell network.
Thanks for any help.

how often does it change ? is the running at home or the pc u are tethering with it ? are you using a 3g network service for a server

Every couple minutes at least. One minute it's for example, something like 208.54.27.50 and in a matter of 5 minutes the last two digits could be changed. I use the 3G hotspot at home and there's no difference from that and using the phone's browser itself. I do not use T-Mobile 3G to operate any servers.

If it is via your provider you have no control over it changing as they assign you a dynamic IP. If you were at home you could set it to a static local IP (Over WiFi) but outside your LAN on T-Mobile's WAN you have no control over DHCP

All I use for internet access on the go and at home is the 3G hotspot that I get from my phone. Would I need an actual Wifi connection from an ISP other than T-Mobile to set it to a static local IP?

looks like that just cant be done.. either ur site changes ur auth to id pw based one(atleast in ur case)
or ..
if its a job of just checking somthing, u can find a friend or family member with a 24/7 online pc(with a a static ip) and just do the job thru a remote desktop connection

All right guys. Thanks. Very much appreciate your thoughts and for not flaming me due to an obvious answer. Thank you again.

Tmobile Blocking tethering - im rooted on cm7

Well yesterday I was tethering like i've done every day on my device and I kept getting redirected to a tmobile webpage telling me to pay an extra $15 per month for tethering.
My T989 Sgsii is using CM7 and there is no tmobile tethering software on the device. Is anyone else able to tether? Im on a prepaid contract have have tethered every day for free since last december.
Im guessing tmobile is blocking my tethering on the network end, since all blocking/tethering management software has been removed from my phone.
Any advice? If i cant tether, i cant use up all 5 gigs i pay for, so ill probably get a cheaper plan or switch to straight talk.

Seems like we have the same problem?
I made a post on the Nexus One forum aswell.

Yup. Looks like we both have the same problem.
Tmobile must be somehow able to detect when my computer tries to hop on their network and blocks it.
Can anyone else who uses tmobile comment on this?

They're mainly catching you by looking at the headers of your http traffic, and assuming that http requests with desktop browser strings are coming from tethered PCs. If you change them to spoof Android's browser, T-mo can't tell the difference.
They could probe more deeply if they wanted to, but as a practical matter, they don't. If they blindly dip the net into the stream and just look for http traffic with desktop-browser identities, they can effortlessly catch 99% of the people who tether.
If you really want to hide your tethering from them, just subscribe to a PPTP VPN service like ibvpn.com. It's around $5/month (~$37 if you pay for the whole year up front), it'll TOTALLY hide what you're doing from T-Mobile (because all they'll see is an encrypted bitstream), and also comes in handy for using a wi-fi tablet with public access points (the reason *I* subscribe).
Just be careful to make sure your network connection doesn't drop while you're tethered, because there doesn't seem to be any way to tell Android, "Establish this VPN whenever there's connectivity, and DO NOT send ANY data via ANY means besides the VPN". If your connection drops, the VPN will break, and if the phone reconnects to T-Mo a half second later, it'll just silently send all network traffic going forward straight through T-Mobile until you reconnect to the VPN.

best advice ive received so far - i was wondering how they were able to tell i was tethering. so i guess ill just need a browser that supports changing of the user agent? or is it more complicated to browser spoof?

I got the same message two days ago with a prepaid account on a CM9 exhibit ii
I'm not sure just changing the ua would help though because I'm getting the redirect on my android tablet as well, not just my laptop

The headers also give them an idea if more than one unit is being serviced, ie: hotspot. Encryption hides this as well. Bottom line? They will see tethering if they look for it.

I just use Opera. It hasn't failed me yet.

I believe the tether detection works by looking at the TTL for packets. It would be more than it should be if the client is using the device as a gateway. Thing is HTTPS still works once you've been "blocked" as well a bunch of other protocols, so it looks like they are just setting a captive portal for port 80 traffic. That said, I have a Zentyal VPN set up at home on my 50mb/s line, so once tethered I VPN into my home machine which then resets my gateway on my laptop to be the gateway on the VPN machine at home. This redirects ALL traffic through the VPN effectively side stepping t-mobiles blocking altogether. So as long as they still allow any data connections over my data plan while tethering than I can access everything like normal. One positive side effect is that general browsing seems to be MUCH faster given that the traffic is really actually being downloaded from my home connection and being siphoned through the VPN rather than having the phone itself and t-mobiles crappy gateway doing all the work.

Not to mention, everything is encrypted so t-mobile cant track any of my surfing habits either. I dont know about you all, but I tend to trust my ISP a little more than my wireless carrier.

So the issue has been solved.
I can tether on tmobiles network with no issues as long as i DONT use google chrome. Safari and Firefox access webpages no problem. Chrome has a user agent string which tmobile is able to see - and block by default on their network.

I'm on Tmobile w/ my Droid 3, stock OS. I tether once in a while, only use Chrome for browsing, and I've never gotten redirected.

I was using chrome all day today. First half of the day it was fine (and every other time before this but I've only had them for less than a month), but then after I started pushing maybe a gig through netflix in addition to using chrome THEN chrome stopped working. Had to use a user agent extension to get chrome working again.
So it might be a trigger set off by data usage to THEN check for the user agent

Makes sense. TMobile doesn't appear to have refarmed Portland yet, so when I do tether, I don't end up using that much data, what with being stuck on 2G and all.

Please look at my post regarding T-mobile tethering
http://forum.xda-developers.com/showthread.php?p=26649587#post26649587

The methods employed by t-mobile to detect tethering are quite frivolous and an asinine move on their part. Their detection does not even work properly.

fix for Tmobile blocking tethering with usb cable
To fix your issue just change your user agent in IE or Firefox. If you dont know how to do that just google change Useragent for IE or firefox.
Hopes this helps.
