Question

Japan fiber internet disconnect every 24hrs: fix? New ONU?

by Jul 17, 2015 8:33PM PDT

I have fiber to an ONU provided by the ISP, CAT5e to WAN port on Netgear R7000, AC1300 Wi-Fi bridge to R6250 with CAT5e to this PC. Netgear firmware with latest update. Several other devices on the R7000 Wi-Fi. Everything works perfect for 24 hours, then the R7000 loses connectivity to the ONU. Router and modem resets do not work. If I connect the ISP provided router for 20 seconds, then reconnect to R7000, everything works perfect for 24 hours again. No power cycles or resets needed to ONU. Just plug in ISP router to power, remove the CAT5e cable from the R7000 WAN port, plug into ISP router, wait for lights and audible click (about 20secs), plug back into R7000 and everything works again for 24 hours. I've been doing the same procedure for a month now with no change. I have all settings matching: static IP, cloned MAC, ISP DNS, same host/router name. I believe it has something to do with the ONU. Could there be some signal the ONU checks for after 24hrs? Would a new ONU solve the issue? Could it be the ISP side checking for their provided router? The Japanese ISP (au kddi) customer service has very limited English and this issue is far too technical for them. There's just got to be a way without having to use the ISP provided router as the gateway, the interface is all Japanese. Please help. This daily routine has to go. Thanks for reading!

to WAN port on Netgear R7000

Right there is where I see these fail. Either not work at all or have issues.

If the ONU does not have a bridge mode, then you have to use the Netgear as a HUB and WAP and never use it's WAN port.

The Netgear R7000 works perfect for 24 hrs, then the ONU
by runrte Jul 19, 2015 4:36AM PDT

stops communicating with it. The Netgear R6250 does the same thing when used as the main router. I even tried dd-wrt on both routers with the same results. The bridge works better with the Netgear firmware. Exactly 24 hrs, no matter what time you do "the fix procedure", the main router will stop. If I plug in the router provided by my ISP to a power outlet, then connect only the cable from the ONU, wait 20 seconds for the lights and click, then plug it back into the main router, it works perfect again. I tested the ISP router with 3 days up time, no issues. I think my next step is to purchase a new ONU to test. When I told the ISP installation team leader that I planned on using my own router, he told me that the ONU and router were designed to be used as a set. I had never heard of this before. I didn't think the ONU would care what router I connected to it. I was hoping for some clarification before making the purchase.

Remember

I did write or have issues. If you don't believe them I can't help you with that. I see someone checked out lease time so check that out too but as written I didn't expect trouble free operation.

sounds like lease setting in router
by Jul 19, 2015 5:30AM PDT

ISP lease is probably 24 hours and then it drops. Reminds me of the dialup modems that would disconnect after awhile if there wasn't some keyboard or mouse movement to "keep alive". Check the lease setting in router.
