Hey all,

Was hoping someone could advise if any known issues in Brackenfell and surrounds with Vumatel/Cool Ideas? I'm on the 200/200 package but appear to be limited to 100/100. Only noticed this after I got back from holiday and last I checked which could of been a few months ago, this wasn't an issue.

Possibly a device being sticky at 100Mbps?

Doesn't appear so. Same device came right after 17:30 and other devices were also producing similar results

Cool, but always best to check negotiated speeds on actual ports for this sort of thing. As the sub 100Mbps result is a typical giveaway.
