I have Centurylink VDSL2 with 60down\5up. When it is working it works great, and speed test is showing good results. I've had a problem that about every 2-3 days, some devices on the network can no longer get HTTP traffic (other ports like ping are still working). It isn't the same devices every time either. Power cycle the modem has always solved the problem.
I previously disabled wifi on the C3000Z and moved the wifi \ ethernet traffic to a separate router to reduce some of the load on this box, such as local LAN traffic - there are only 2 devices connecting to the C3000Z which is the separate router and my VOIP OBI box. However, when I do experience this web connectivity problem - I find that resetting the C3000Z modem (not the downstream router) is actually what fixes the problem.
Any suggestions what I can do to fix or at least troubleshoot this?
