45+% loss when pinging server to router
Posted on 2003-03-14
I have a network of 250+ restaurants. Each has an NCR 3234 server with an integrated ethernet port connected to an Efficient Speedstream router. We use sco unix openserver 5.0 (and before you suggest we switch, we are narrowing down vendors). I have been having problems sending downloads to one restaurant. From the restaurant server, I get a 40+% packet loss between server and router using a packet size of 1024. If I lower it to 16 bytes, I still get a loss of at least 5%. I have replaced the ethernet port (mother board) and connected the server and router to a UPS. I have also moved the equipment and cables as much as possible to minimize any interference it might be getting. I can connect a laptop to the same cable and I have no problems (0% loss). I tried both uucp and ftp and can pull files back to our corporate office, but can't resend the same file back. Any ideas of what I might be missing?
