Superhub : Connection Drops.

[MacmillaN]

Just so happened to get mysterious connection drops on the Superhub again, took over 25mins of rebooting Superhub restarting computer many times in order to get resolved.

Although on my last attempt i did remove the ethernet cable and switch ports, which seemed to do pick up the connection again. (It does seem to happen quite often, but it could just be a ethernet cable issue.


I am not sure though, so was hoping someone with more knowledge could shed some light on it.

Here is some logs from the Router Status Pages.

With the superhub, if the top light turns blue then it means it's connected. At a glance, your power levels and such look reasonable so it implies that the connection itself was ok but between your computer and hub was the issue.

Next time it happens, look at that blue light - if it's green, then there's an issue, if it's blue then it should be online.

ya, have you got anything else connected to it apart from your pc (e.g. xbox or ps3). It sounds like it is locking up rather than losing its connection to VM.

Kushan-Will make sure to check the blue light, when it happens again.

General Maximus-Possibly had a Laptop/iPhone connected at the same time as a Desktop Computer.
