R7000 and bandwidth control
I am using my R7000 behind a DSL modem as LAN and WiFi router and since a couple of weeks I am recognising an odd behaviour - when one of the other clients connected to the R7000 is starting a downlo...
- On an asymmetrical link, where the upload rate is a fraction of the download rate it’s possible to choke the network with upload data. So for example with a large TCP download where packets are acknowledged by the receiving computer then there can be a corresponding high upload of data, and if the upload rate limit is significantly lower that the download rate limit then the Internet connection can grind to a halt. The first few paragraphs of this .pdf might explain better than I can; http://www.sigcomm.org/sites/default/files/ccr/papers/2012/January/2096149-2096158.pdf
Yes - I did use AP mode while modem was in router mode
I have a suspicion - all wired clients now run on Gigabit LAN up to Modem - my DSL bandwidth is max. 16Mbit - as a result maybe 1 client can eat up all available bandwidth. During a regular download (e.g. 700MB ISO image file) I saw the client eating up full bandwidth on the modem. The odd this is after taking LAN down to max. 100Mbit instead of GigaBit all looks to be ok again again.

Thanks - that might perfectly explain the problem - I have download 16MBit, upload 1.5 MBit - I'll check out the documentation you provided as well. It sounds by throtteling the general bandwidth to 100MBit in the local LAN I can somewhat mitigate the problem for now until I are able to upgrade to more outbound bandwidth.
