timmmay:johnr:timmmay: Why would you fault check the PCs when the router traffic meter and Vodafone traffic meter don't agree?
My assumption is there's a bunch of traffic hitting the modem for some reason that isn't getting to the router, but I'm not any kind of a networking expert.
You would check them for a virus / malware to make sure this is not causing extra traffic
How would this traffic get counted on the Vodafone usage checker without being counted by the routers usage counter?
Router could be faulty or the data interpreted incorrectly by end user. Not saying that is the case but it is how it could.
