So I'm using a Windows I-mate and a Nokia phone. Both have GPRS connection of the same company.

When I connect them to my PC one connects as a modem and the other as a Broadband connection. I want to be able to use both at the same time to get the facility of better a speed (connection here is that bad).

It doesn't work like that since only one of the connection is working (Dial-up), the other remains inactive. It's not deactivated though.

Please help! I've been looking into Google but I couldn't find any answers.

Help us help you! There isn't not even enough information to start...

Do you have only GPRS, or 3G as well in your area?

What i-mate model, what Nokia model?

How are you thethering the devices? USB, Bluetooth?

How are you connecting? What number are you using?

I'm sorry. I didn't know what to put in.

Both phones are connected to the internet using GPRS.

I-mate JAQ (Is that the model? I think it is), Nokia is 6300.

I'm using USB. Nokia is connecting as a Modem and I-mate as Broadband.

Ok, thanks... If you only have GPRS in your area then it won't make any difference.

The connection type is just different because of the software used, but it will be limited in speed by the mobile connection. "Broadband" is just because it uses a network adapter instead of "dial up" which sees the phone as a modem.

In both cases however the phones are connected via GPRS, which is the same speed regardless of what the connection is...

Anyway I can use both at the sametime so that I can get a better internet speed. I'm downsloading at 10KBps. So if I connecting both at the sametime I should be getting 20KBps or something around that right?

It's not working like that.

Only two boxes are lighting up. The other two remain black.

No, most system won't have this kind of "load balance" enabled, and only one connection will be used.

You are looking for connection aggregation software/routing.

It might not really be worth it for GPRS connections, and it will only really work for multiple simlutaneous TCP/UDP connections to multiple remote servers.

That link I gave is one example (although i just searched for that on google and didn't look in depth at it). Its not really a simple thing. MS Windows has built-in connection aggregation through multiple modems, but this only works with ISP support and wont work in your situation. You can quite easily create multiple connections - just set up both phones in data modem mode (I'm not sure of the method for each, but its usually fairly simple) and then create the dial up connections on your computer. However this will just mean that one of them gets used while the other sits idle until the first one is disconnected - you need special aggregation software to split up data over both and it probably wont really do what you want on such a small scale.

The typical use for software like that is where you route certain computers/networks/applications over one connection and others over another connection (eg if you had two connections that had different costs for different services), or if you simply wanted backup internet connections without getting enterprise class connections and your own AS with BGP etc.

PS: Please don't pull me up on 'UDP Connection' - i was just simplifying.

So you're telling me to download that file from that site?

The cost is fixed though.
I pay at the beginning of the month.

What's UDP connection?..

I've never used that software nor am I an expert on it. I'm just guiding you on what to ask for, and telling you it's not so simple once you understand how internet connections work. Just search google for Dial Up Connection Aggregation.

UDP - The internet is a big network of computers (somewhat like the road network, where there are often multiple different ways to get between two places) communicating via the TCP/IP protocol. When you request a web page, your computer sets up a TCP 'connection' between itself and the server holding what you requested. Imagine this as kind of laying an imaginary pipe along the roads between your house and the dairy (the computers choose which ever path that suits best) and then asking the dairy to send you a bottle of milk that follows this 'pipe.' One of the things that the computers do is make sure that everything that went into the pipe comes out of the pipe correctly. With UDP, the dairy just sends you some milk arbitrarily, and it doesn't know or care whether you end up getting all of it or not (this is useful for video and voice applications where a tiny bit of missing data doesn't make a difference and the time overhead of checking everything is not worth it). Thus there is no 'connection.'

Now what you are trying to do is only useful if you have more than 1 of these TCP 'connections' at a time, because you can't split a big pipe into two smaller ones unless it gets split back again somewhere (you could rent a server and get specialised software I suppose, but this would be expensive and probably pointless). But it is useful if you want to send one pipe over one ISP, and another pipe over another, or if you simply wanted a backup ISP to send all your pipes over if the first one failed. But for you it would only really be useful if you are drying to do a bunch of things at once - and for a connection which is still going to be very slow I doubt it'd make much of a difference for you. I would reccommend getting a data card and a booster antenna if you are just trying to do this at one location, or maybe you if you're a DIY Wireless dude then you could somehow jimmy up a booster antenna or WokTenna the cellphone. You could maybe get a cheap cellphone and somehow build a waterproof WokTenna (antenna made out of a wok) or CanTenna (same thing but using a Can instead of a wok) and use the cellphone as the collector and mount it to your roof pointing towards the nearest cell tower (or in whatever direction gets the best reception).

I suddenly find myself intrigued by this software so I might actually download it to have a play and report back later. Hmm I also suddenly feel myself wanting to build a Cell WokTenna for the hell of it :)

Yeah I guess it is pointless.

I just wish I could somehow connect the Noikia through LAN then bridge it with thr I-mate.

That is a strange desire. :P

You are partly right.

If you can get both connections to work as dialup devices, you can tell Windows to use Multilink PPP (MLPPP) over both devices, which will aggregate the links nicely. All traffic will be split across members of the MLPPP bundle.

Pretty much all mobile service providers I've played with support MLPPP, so you may find it works - but it will be dependent on your service provider supporting MLPPP.

Oh, OK I stand corrected. I didn't think you could do MLPPP for mobile but ok if it works then great. In that case: http://support.microsoft.com/kb/307849

No harm in trying I suppose. Still, I think you would do better to get a bitter signal (or do both!)
