But unless you spend 20€ per server for Gigabit cards, it will still be slow as hell... The wifi is not only bad for your throughput: 48MBit/s is low compared to 120MBytes/s for direct disk access. Its actually half of that because wifi is half-duplex by design. 100MBit will be a bit better as you then have ~12MByte/s per direction. Only Gigabit will really keep up with the throughput of the disk. Additionally wifi has the ethernet-latency plus the wireless-latency plus the latency of half-duplex and collision-detection. It is a) no wonder your users will be complaining about the poor performance (mine are still complaining while I have a dedicated GB-link) and b) its no wonder drbd complains and stops the sync...
