I had purchased a mk3 surf soho as it was stated to have 120Mbps throughput. I have it on the latest firmware however I notice a very big issue.
I only have a 50Mbps internet connection and if I am maxing that out downloading, the cpu on the router is fluctuating around 88% and into the 90s. (I can’t imagine if I had chose the 100 Mbps internet but that’s not my issue at the moment). My issue is that when it eventually peaks and hit 100% my other wired (directly attached) devices become unreachable. I’ve had constant pings going and when it hits 100% it starts timing out to them. Their interfaces are still up and there is nothing in the router log or the devices log, the router just doesn’t send/receive any packets to the devices.
So how is this a 120Mbps throughput router when 50Mbps is causing 100% cpu load and dropping other physically connected devices?
