Since moving to bigpipe I have been having fairly regular connection issues, I expect these are on my network and nothing to do with Bigpipe themselves, but they never happened with myrepublic before I moved and I am hoping someone can point me in the direction of a fix.

Every day or two when placing high load on the connection (generally a minute or two after starting a steam or usenet download, something that will push over 100mb) the connection to the router drops out. I am connected via ethernet and can no longer ping the router, all clients connected by wifi also drop off. A reboot of the router gets the network connection running but I have to reboot the ONT or disconnect/reconnect the pppoe connection before the internet comes back up.

My first instinct would be to blame the router (archer C9) but I have swapped it for an Archer C3200 and get the same issues.

Its a little hard to diagnose as it only happens every couple of days and I have flatmates that wont tolerate me taking the network off line for hours for testing.

Anyone have any ideas where to start here?
