I haven't been able to find any information concerning this and I was hoping someone could help me. I've found posts and information on problems with not receiving packets but not with not sending packets. I'm connecting through a RCA broadband modem with Roadrunner cable service and a 3COM Etherlink NIC. When I start my computer, it never sends packets. I have to pull out the ethernet cable and replug it to reconnect. After a few tries, it'll connect. Occasionally my computer stops sending packets and I disconnect and I'll have to reconnect by unplugging and replugging the cable. What's the problem?
