slow connection

[macsig]

I'm not sure this is the right place for this kind of questions but I couldn't find a more appropriate section.

I live in a two-story apartment and my main connection is upstairs where the cable arrives and I have a time capsule to provide wireless connection.

I can have connection even downstairs but in some places the level is very low so I have added a Airport Express. Now I have full coverage but the speed downstairs is very slow (perhaps less than half of the speed I have upstairs).

Is there any way to tune the level of my connection?
Any tool to verify there is the bottleneck?


Thanks

The maximum wireless effective throughput is halved after the first retransmission (hop) that is made. For example, in the case of two routers connected via WDS, and communication is made between a computer that is plugged into router A and a laptop that is connected wirelessly using router B's access point, the throughput is halved, because router B has to retransmit the information during the communication of the two sides. However, in the case of communications between a computer that is plugged into router A and a computer that is plugged into router B, the throughput is not halved since there is no need to retransmit the information.

Thanks for your reply.

Anyway I feel downstairs is really too slow compared to upstairs.
