I was using this pair of networking hardware for low-frequency automated trading. For whatever reason, this particular WiFi bridge rewrites the checksum from corrupted data packets and forwards them on over its wired interface. The results were disastrous (to trading.) Since the bridge rewrites the checksum inside the network packet, any given host connected to the wired interface of the WET610N is unable to detect corrupted data packets. Thus, bad data makes it up the TCP/IP stack and into applications. In other words, you get corrupted market data, lots of broken network connections, corrupted file downloads, and md5 hash values for downloads that never match up to what's listed on web sites. I've upgraded the firmware on all of the devices, and have had no luck removing the data corruption problems. I've trawled all over the web, and it turns out other people are having this problem also: http://forums.smallnetbuilder.com/showthread.php?t=2378 Do NOT buy this bridge!
