Query: Beware Buggy Firmware

This review refers to firmware 1.45.3 dated Sep 26 2003. HTTP port 80 is port forwarded to a web server. The majority of the clients can reach the website fine. But for some clients (in particular clients on Southern Bell DSL and international clients in Singapore), the router will drop connection. This problem is particular to the Linksys BEFSX41, as replacing the router with another of a different brand (Fortinet) solves the problem. I'll never buy another Linksys router again.
