I have a CDMA wireless card that plugs into a usb port

accessing a nationwide network here in India

Is there any way to use that at the same time as the internal wireless

connecting to the hotel network to maximise my bandwidth.

As soon as I activate the usb port card it seems to override the internal wireless

or even the LAN cable connection.

Running under Win XP

what about http://www.nat32.com/?

also http://www.r1ch.net/stuff/forcebindip/ seems useful

I have always been wondering;

I plug my notebook into the LAN socket of the router and at the same time use the wifi connection;

theoretical it means 2 connections and will my download speed be doubled ?

No. You're limited by the bandwidth between your router and the internet. But, if you connect to your own router via ethernet and then connect via wi-fi to a neighbor, internet cafe, etc. and you employ the software solution(s) mentioned previously, then you could improve your bandwidth considerably. "Network load balancing" is the term.

You can check how the computer uses multiple network interfaces by looking at the routing table. At the command line, type netstat -r:

IPv4 Route Table
===========================================================================
Active Routes:
Network Destination        Netmask          Gateway       Interface  Metric
         0.0.0.0          0.0.0.0      172.25.14.1     172.25.14.10     25

0.0.0.0 is the default route.

When you connect a 2nd interface which has a default route as well, the computer will choose the one with the lowest metric. Windows automatically assigns a lower metric value to a faster interface.

So if you want to have double bandwidth by connecting 2 networkcards to the same network, you have to team them first. The software to do this is usually provided by the manufacturer and provides a single teamed-interface to the operating system, on which 1 IP address will be configured.

If you connect your PC to 2 different networks, the routing table will decide which connection is used.

Thanks for the info and suggestions.

I can see the metric on the netstats and the network in use is the lower value.

I have tried the forcebindip, but it does not seem to allow the programme to connect

to the network that I specified.

Downloading the evaluation version of NAT32V2 as I write this.

Will see if that can do the job.

If you want to use 2 Lancard for connection Internet, it is easy for Desk top P/C with Windows 7 Ulitimate version.

You don't need buy Load Balancing, Windows 7 included load balancing software.

However, it is for make extension band width, it can not help to improve internet speed. Of course, internet quality should be satify with 2 lines.

you just install one more LAN card in your desk top PC. and plug in other internet.

Setup, you can learn at Misrosoft.com.

However, it is for make extension band width, it can not help to improve internet speed.

Can you elaborate on that, please? How does it increase bandwidth without increasing speed?

Perhaps an electrical analogy will explain it.

If you have a 12v battery and you are drawing 10amps.

Then you connect a second battery in parallel you still only have 12 volts,

but you can draw more current.

Perhaps an electrical analogy will explain it.

Then again, perhaps not.

Am I mistaken that speed is measured in units per time, usually in ISP parlance: Mbps?

So, if I have a download speed of say, 3Mbps, how can I download any more than 3,000 bits in any given second? i.e. If the "speed" is provided at 3Mbps what dimension is added by increasing "bandwidth"?

How is bandwidth measured, if not by speed?

In most cases you will not see a benefit.

Not only "speed" but also jitter and ping response.

Consider carrying out speed tests on both connection separately, you might use one for torrenting while keeping the other from normal browsing.
