Hi friends !

I have opened an internet cafe here in Kigali, Rwanda. And for this, I have subscribed Wireless Broadband Connection of 256 Kbps/128 Kbps download/upload. (Some experts here say that this speed is too low for running an internet cafe.) But, surprisingly, almost 90 % of internet cafe here in Kigali are running on same speed as this is the economic pricing of ISP.

I visited some internet cafe and I feel that they are running OK. But, basically, I am from India and I there, ISPs charge comparatively lower money for business internet connection. But here, going over 512 Kbps is too much expensive. The pricing of ISP is surprising !!!!!!

Right now, I have connected only a single computer (with public IP given by ISP) to internet and downloading Microsoft .NET Framework 2.0 (22.4 MB). The download speed is varying from 16 KB/sec to 30 KB/sec.

Please tell me how you "experts" calculate the exact available internet speed and outer interface (Public IP) and what bandwidth is required to run internet on 15 PCs.

Note: I will do Internet Connection Sharing on the Server PC where I have two NIC cards, one for public and another for internal LAN.

Hi all !

I applied the tips and online tools that you provided. Let me tell you want I did. (Please see the snapshots of the tests.)

I used only a single PC that is connected to ISP (Broadband Wireless) with public IP address. I did not run  any other application, process or any download while testing.

Method 1. I downloaded an Audio Driver from Dell site with Interent Explorer. You can see that Data Transfer Rate is showing: 72.7 KB/sec. IT IS NOT TRUE because the data download was too slow. And according to the formula (QEMS's Comment), it results to 581.6 Kbps. That is not possible because I have subscribed only 256 Kbps/sec and for that also I am very sure that my ISP is not providing that speed.

Method 2. I downloaded the same Audio Driver from Dell site with Firefox. You can see that Data Transfer Rate is showing: 8.6 KB/sec. It results to 68.8 Kbps/sec. If It is true then I am getting very less compare to what I have subscribed.

Method 3. I performed the on-line speed tests also and the speed results are varying.


Please tell me whether the ways I used to calculate the speed (in Method 1 and Method 2) are right or not. And which test can give me the exact speed I am getting.

Also tell me, if the speed I am getting is tremendously less than 256 Kbps (that I subscribed), should I conclude that I am being given "Shared Bandwidth" !!! In that case I will complain against my ISP because before subscription they told that "256 Kbps / 128 Kbps (download/upload) will be completely for you".

Regards.
