Doubt it's the router, have a Asus RT-AC66R.
You mean this one? Just saying.
Sounds like Leo must have said something grumpy about Comcast.
Regularly.
Start downloading a single podcast and everyone's internet speed comes to a screeching halt. Local traffic on the network seems fine during the bog down. Access to our server remains speedy.
That means 6233638 interpreted your comment that it "kills their network's internet access" comment correctly, rather than what I interpreted it as, though. It could have gone either way. I thought you meant it brought the modem or router actually down (requiring a reboot of one or both to fix), not just "everyone's access becomes slow", which is probably a different thing.
QOS, properly configured, will solve that. Effectively, bandwidth limiting on MC's end
is a QOS feature.
However, again, I don't think having some sort of option to "download podcasts slowly" would be a bad thing. But, for the record, that is very likely a problem with the router itself, though. I'm not sure exactly how MC does the downloads, but I bet it isn't anything special. It probably just opens up a few HTTP requests for the files (however many it does simultaneously) any then comes what may. The fact that it bogs down the entire network, but not internally, indicates that the problem is on the WAN side of the router (becoming overwhelmed with the traffic and then failing to respond to subsequent WAN requests).
I still maintain that, especially in a corporate environment (even a small one), if one computer on your network can "bring down" (either crashing entirely, or slowing to a crawl) your entire WAN access, then
your network is misconfigured or inadequately designed. At a company, that's the network's fault.
At home... Well, if it happens to other people, then an option to be more gentle would probably be good.
