There is no router connected. Any help or info anyone might be able to offer would be most appreciated.
Thanks. |

kudos:1 | Re: [Connectivity] Connection dropping randomly Yea no router would matter in this case but thanks for Clarifying  That said that usually indicates an upstream problem but obviously you actually should be in good shape. I put a trace on the connection because I can't find anything with the group but will have to watch it for a couple of hours or longer to see what happens.

| Thank you so much for taking a look at this for me. Like I said it has been happening randomly. I had tried to read up a little on the errors I was getting, and it seemed that, more often than not, it was a cabling problem, usually outside. Is there anything I can look at that might be able to tell me if I need to make a call to have an RCN tech come out and look at the cabling? (Or, better yet, is there something I can do to fix it? I am more than willing to invest in a little equipment to monitor or test the cable.)
Thanks again for your help. |
