bandwidth issue

[Squawk7777]

Hello All,

I am temporarily using an Orange 3G USB stick for my internet connection. I noticed that some programs cannot establish their connection to the net, one of them being MS messenger. I tried many things, closing my browser and misc. programs running in the background, all to no avail. I wonder if this is due to the limitation regarding bandwidth. If it is, can you measure how much bandwidth a program uses?

Thanks,

Unlikely to be bandwidth.

Not enough information - what do you mean by "cannot establish their connection to the net" - what are the symptoms?

What do you see in a trace? (Using Wireshark or whatever you prefer.)

How are you trying to connect anyway? - "using an Orange 3G USB stick" tells us that you're moving the bits using radio waves, but nothing else.

GtW, MS Messenger cannot connect to the internet every time it tries to over the 3G connection. The error code I get is 8000402a (unable to establish a connection). Once I use regular (even slower) WIFI it has no problem establishing a connection.

The internet connection device in question is an Orange USB modem, that uses 3G(+)/GPRS/ EDGE technologgy. Am also using Vista :uhoh: :eek: :{ :yuk:

It sounds to me more like a network connection / routing problem than a bandwidth problem.

I obviously know nothing about your setup, but if your system is set up to use one network card and one service provider and you then change both network card and service provider, there may well be some settings in some applications that need to be changed to reflect the change in the network layer.

I don't use Messenger, so I can't tell you what can or should be changed.

What is your 3g signal strength? Data connections do not like low or variable signal strength.
Once I use regular (even slower) WIFI it has no problem establishing a connection.
WIFI should not be "even slower". Is the WIFI signal poor as well?
It would be sensible to turn WIFI off if using 3G and vice versa.

Yes, but, what's happening at the TCP/IP level? Failure to perform DNS resolution? Failure to find a route to the site? TCP connection attempt rejected (RST sent in response to SYN)? TCP connection attempt timed out (nothing sent in response to SYN)? Failure to negotiate SSL credentials? Or what?

And you still haven't given details of the ISP service you're connecting to. If you've bought the wrong sort of service you can end up in the network operator's walled garden with either no internet access or restricted internet access. Perhaps unlikely if some sites/applications work but not others, but it would still be helpful to know. So: What's the name of the service you've bought, and what's the Access Point Name?

It's not a bandwidth issue at all... Works fine on my O2 Mobile Broadband.

srobarts,

The Dongles are designed to pick the strongest connection available, so if WiFi is in the area it will connect to that rather than HSDPA (3G in other words).

I would suggest speaking to Orange and finding out if they prevent it working or anything, it should work without any issues it doesn't use a lot of data to run.
