My friend's Mac takes down entire networks.
This happens on both Wireless and Ethernet.
This has happened on 4-5 different routers in 3 different locations over 2 different states.
When her Mac is disconnected (usually within 1-7 hours of it being connected to a network, seemingly at random), the entire router is taken down. In her last school year (dorm), this meant that the internet for her ENTIRE DORM was taken down for nearly the entire year because of her computer (we didn't realize it was her computer causing it until recently).
This happens on both Mac and Window partitions, and the Windows has been reinstalled 3 different times (and the HDD was swapped once).
Am I correct in believing this must be a MOBO config issue or hardware? If so, is there any fix?
Thanks.
EDIT: I should add that restarting her computer and/or the router seems to have no effect on getting the network back online. Shutting her computer down for 15 minutes and then restarting the router also seems to do nothing. Once it's down, the router is in borked-mode for at least an hour or two before it starts functioning again.
EDIT2: A DoS Virus? Over 2 partitions booting into 2 different OS's, both of which have been reinstalled a total of 6+ times over the course of 2+ years? With all due respect, it simply isn't plausible. As an aside, I know she practices intelligent internet browsing and does run mbam already, but even if I didn't... it simply isn't plausible. I am fairly certain it is either a MOBO configuration or hardware issue.
