Hi everyone,
I've been havinf some issues recently with some clients, where suddenly their modems lost connection to the Internet or something like that, since their devices (smartphones, tablets, etc) tell them: "limited access" or "Connected without Internet". I am not sure if this situation is related to noise problems on the node or if it is the cable modem, which could have the issue. I check the noise of the clients modems that are reporting this issue more and it is relative good, the cable modems have CNR between 22 and 34 dB or higher, the return potency is normally between 43 dBm and 54 dBm. We use refurbished cable modems like Ubee DVW326, Arris DG1670A and Arris DG860P2, so I haven't rule out that maybe the modems could be causing the issue.
Have any of you had a similar problem?
Best regards,
