Hello, I'm trying to switch my VoIP network over to Full duplex. Each time I call my ISP an direct them to switch it over the whole netwok goes down. I'm assuming my linksys WRT310N is not supporting full duplex. I can find no setting of it but I assumed it would automatically switch over. Does this router actually support full duplex? I called support and they said yes... Is there something else I could try? And when I say the network goes down I mean I cannot even ping my gateway, or I can ping it for 10 seconds then it drops off for 10 minutes!
