Since everyone is in the networking mood, I have a dilemma like others. I posted on it last year but cant find the post to renew it. Firstly, I am unicast. I have 2 NIC cards in PC, one for internet, one for E1.31. The IP address of internet NIC was set to obtain automatically but I see on looking at it now at some point I must have changed it to IP: 192.168.1.150 Subnet: 255.255.255.0 Default gateway: 192.168.1.1 DNS server: 192.168.1.1 I had someone look at the problem via teamviewer last year so it was likely him that changed the above as I dont think I would have (especially the DNS change). The details of the E1.31 card are: IP address: 10.10.10.1 Subnet: 255.255.0.0 Default gateway - None When it comes to testing this year I would really like to be able to Teamview into show machine while standing outside, but I cant have the internet going at the same time as LOR running. With internet plugged in as soon as I start LOR control panel the rest of the network turns to crap, including wireless devices e.g ipad, laptop. My internet NIC goes to a modem/router switch, I also have another switch off that and have tried plugging it in the plain ole switch as well, no difference. The person who Teamviewed in to my machine last year did a few things with Nortons thinking it was Nortons that was causing it. This year I dont have any firewall except for Windows one. LORCommListener is allowed through Win firewall. I can probably turn firewall completely off but surely I tried that last year and it didnt work. As soon as I unload LOR control panel Im back on again. I brought a USB->ethernet dongle a while back for other reasons, tried that for internet, same problem of course. Anyone out there who can help me problem solve? JCMarks has the same problem except that he uses HLS so is wanting to try any suggestions as well.
