fragm.threshold, data retries, rts treshold, rts retry limit - Networking

I live in a hotel in the south of france for 5 months because i'm doing an internship here. The only internet available is a wifi-hotspot but I can only reach it if I hang my laptop outside of my window and only after changing advanced settings on my laptop's wifi-settings ( fragment threshold, data retries, rts treshold, rts retry limit) :lol: . It would be so much easier when I could just hang my MDA Varia out of my window and access it's WLAN via bluetooth but unfortunately my Varia doesn't get a good connection with the hotspot.
Is there any possibility to change the fragment threshold, data retries, rts treshold, rts retry limit etc on my Vario?

gprs / csd?

Whats the diff between csd and gprs. Right now I created a new connection by doing start; settings; connections; connections; modify (internet settings). Under "My connection" I have it set for "cellular line (GPRS)". Under baud rate it is 19200 (why so slow?). Clicking next I have "wap.voicestream.com". This works but is really slow. Is this the correct way to use GPRS or is this CSD? If not, what is CSD? Is it better. Sorry for so many questions but I really dont know much about this. I have t-mobile in the US (southern california).
CSD (Circuit-Switched Data)
CSD is similar to your PC dialing up to a ISP / corperate modem pool for a data connection. For XDA or a cell phone in general, it consumes your air time. (If you make the CSD call during nights & weekends with T-Mobile, air time is free.) You get a 7Kbps avg narrow pipe - pulling an Internet page is very slow, but you can turn off the graphics on XDA to speed it up. GPRS is designed for data, giving you 40Kbps avg pipe, comparable to your PC dial-up speed but you have to pay T-Mobile $20/mo for unlimited data service. See thread

for setup. Hope this helps.

Transfer's speed of data

Hello,
Sorry for my English language …
I use professionally a HTC TYTN, and I find that the transfer’s speed of data via Internet, in connection EDGE/3G with Orange, and in WiFI is very slow: between 90 and 160 (rare) kbit/s in EDGE, between 160 and 285 kbit/s (very rare) in 3G (when the 3G+ with Orange????), between 280 and 500 kbit/s in WiFi on the local network of our company, this last being also supply by Orange in a medium flow of 4.800/5.500 kbit/s.
My HTC TYTN has the French version Schap/3.54b, with radio 1.51. No particular problem, everything works normally.
My 2 Internet access points to Orange (that I change according to the fastest) are: “Orange.fr” and “Internet-entreprise”, and for Wifi, my HTC TYTN uses its own network card with an address IP, a bridge, DNS given by Orange (193.252.19.3 and 193.252.19.4) and the Orange proxy Server for connection to Internet (Proxy Address: 172.16.2.8, http Proxy port: 8000, Sock Proxy port:1080).
My two questions are the following:
1 – In EDGE/3G, is it possible to augment the speed of connection with Orange, and somebody knows it if the 3G+ is soon envisaged? This slowness problem is due to the HTC TYTN or to Orange ? Must we change of supplier to obtain a better speed ?
2 - why, in WiFi, when the HTC TYTN is connected on our local network, can’t I obtain the same transfer’ speed on my HTC TYTN (500 kbit/s maxi, I once have reach 820 kbit/s) that on my computer (5.000 kbit/s)?
Thank you in advance to those that will take time to answer me.

MTU Change in samsung i780 for xbox 360 Connection.

Hello all,
I use samsung i780 as modem (HSDPA) to connect to the Internet. I created a bridged connection (LAN connection from mobile + LAN Xbox) and everything seems ok, but when I try to connect to xbox live the errors comes out: MTU Speed too slow, it required at least 1392. So I downloaded SKTool and I changed the MTU on my i780 - from 0 to 1500 MTU - and then I soft reseted the mobile, but xbox continues giving me same error! any suggestion please?!
Thanks
Mario

How to keep GPRS connection alive

We have a WinMob application that sends and receives data over GPRS; and it works.
The problem we have occurs when the vehicle based PDA goes into an area of poor reception and WinMob thinks the data connection is working but no data is being transmitted. The application currently issues a disconnect request to the WinMob connection manager but WM6.* keeps the data connection.
We would like the PDA to drop the data connection and re-connect automatically when the application resumes data transmission after a short programmed delay.
We have tried changing the PDA's registry setting from ~GPRS! to GPRS_bye_if_device_off and setting a (90 second) timeout and this works. Except that even though the PDA issues a UDP packet to one of our servers every minute to keep a push link alive, WinMob ignores this packet and drops the connection ~100 seconds after connecting.
What do we need to receive/transmit to convince WinMob that the data connection is active? DO we need to issue a http get request after sending the UDP? We don't want to send/receive more data than we need (large phone bills!).

Terminal emulator app for android keeps connection alive. Go to playstore and get it

3G Data turning on when set to off

In one of my other post in General, I found that 3G data is turning on when it is set to disable in the settings on the Dell Streak 5,(Android 2.2 AT&T Locked US version) using 3G watchdog, I noticed I was using 3G data when I was supposed to be using only a WiFi connection. This occurs when on a WiFi connection and you access the Google Market Place.
Accessing the Market Place will turn on and activate and transfer 3G data to and from Google Market.
Turning off background data will cause the 3G data connection to not turn on.
This also cause Google Market Place to not function and states it needs the background data connection to be turned on.
Am I reading the coding wrong below?
Why am I incurring data charges when set to WiFi Only?
Why does Google Market Place need to open a 3G data connection when using WiFi?
Has anyone else noticed this?
Have you went over your data allotment and wondered why?
--------------------------------------------
public static final int TYPE_WIFI
Since: API Level 1
The Default WIFI data connection. When active, all data traffic will use this connection by default. Should not coexist with other default connections.
Constant Value: 1 (0x00000001)
---------------------------------------------
public static final int TYPE_MOBILE
Since: API Level 1
The Default Mobile data connection. When active, all data traffic will use this connection by default. Should not coexist with other default connections.
Constant Value: 0 (0x00000000)
----------------------------------------------
public static final int TYPE_MOBILE_HIPRI
Since: API Level 8
A High Priority Mobile data connection. This connection is typically the same as TYPE_MOBILE but the routing setup is different. Only requesting processes will have access to the Mobile DNS servers and only IP's explicitly requested via requestRouteToHost(int, int) will route over this interface if a default route exists.
Constant Value: 5 (0x00000005)
-------------------------------------------------
public boolean requestRouteToHost (int networkType, int hostAddress)
Since: API Level 1
Ensure that a network route exists to deliver traffic to the specified host via the specified network interface. An attempt to add a route that already exists is ignored, but treated as successful.
Parameters
networkType : the type of the network over which traffic to the specified host is to be routed
hostAddress: the IP address of the host to which the route is desired
Returns
• true on success, false on failure
