I think that Ping device connected to host having LAN access is probably a very simple problem, but the OP is new to SF and isn't always providing the right information in a useful fashion. I think we're probably well beyond the point that comments are useful. I had hoped to engage the OP in chat, but because they are a new user with a 1 reputation they were unable to participate.
I understand the reason for that limitation, but I wish it were possible for them to participate in a chat by invitation from another user with sufficiently high reputation.
Are there any mechanisms available right now that would allow a new user to participate in chat?
