I have a simple network using these Buffalo Tech boxes: WHR-HP-G54 router WLI-TX4-G54HP ethernet bridge
I also have PC, with 100 Mbit/s. duplex NIC. Netgear EVA700 media extender, with unknown NIC.
In case anyone cares, I have found that both Buffalo Tech boxes are solidly dependable and pleasant to use. The Netgear product is pretty rough.
I am experimenting with streaming MPEG video from my PC, to the router, to the bridge, and finally to the EVA700. I am using the wired ethernet port of the EVA700 because its implementation of 802.11g is completely broken.
Anyway, I am surprised that the highest rate MPEG bitstream I can play is about 9.5 Mbit/s. Any faster than that, and the Buffalo Tech boxes appear to be sending data 100% of the time, and the EVA700 can't play the bitstream fast enough.
When streaming at 9.5 Mbit/s. the Buffalo Tech boxes send data for (very roughly) 8 seconds, and then idle for about 2 seconds. I consider this to be the mark of success: the data buffers of the EVA700 are kept relatively full, with bandwidth to spare.
I do see a lot of other 802.11g networks present, but they seem to be spread out pretty well. I seem to recall one evening when I had channel2, and all the other networks were on channels 6 and 11. I still couldn't stream very fast.
The two Buffalo Tech boxes are separated by a wood and gypsum wall, and about 20 feet of air. I will experiment with moving the boxes closer together, but this will require buying more ethernet cables. I have already spent a lot of money on this little project. Before I dive into my wallet again, I'd like to know if this is typical performance.802.11g is described as a 54 Mbit/s. standard, so my 9.5 Mbit/s. "personal best" seems a bit weak. These Buffalo Tech boxes boast "high power," "MIMO," and "turbo." All marketing speak, perhaps.
