Hello

ISP : TMNet(Malaysia)

The light status when the connection drop is orange.

When connection down. All device no internet.. cable and Wifi.

Not really sure if I can connect direct to modem since the modem also carry in TV signal (HyppTV Package) And the Router is use to splits between TV and Internet.

Here the screenshot on Advance status when it is connected

System log is attached.

As I said i is intermitten on and off. When it work. It work. but if I am downloading big files using FTP some times it just stop halfway and fail the xfer. My skype also cutting off and on..

QoS is off.

Advanced features.?? I don't think. Which area.?

Thanks

Hello again,

I can confirm its the Archer C7 issue. Since I replaced it with my Old Asus router and I have no connection issue. Internet Cable or Wifi working without issue. So what should I do next? Claim warranty?

Thanks

@Basj 

Any other suggestion for me to try before consider this as user unserviceable and proceed for warranty claim (RMA)?

Thanks

Basj.

Just an update.. for people that might have similar problem. Good news, for now, atleast, my Archer C7 is working again. What I did?... I don't really know.

But here some steps I remember, what I did and it working again.

1) I switched this router with my old one. The Archer C7 inactive for few days. Cooling off period (I guess)

2) Reconnect it, thinking, last go before warranty claim, but still, quickly I found out it still intermitten internet disconnect.

3) Just went through the advance setup one at a time. Until I get to IPv6 setup. I disable it. Save it. Reboot router. And boom... problem solved. Get back stable internet and no more drop internet. Download big files no more pauses. And speedtest give me stright graph. Before it was normally 2 drops. Usually start high.. than 1/3 throught it drop to half speed and than its will be another drops later..

4) Turn IPv6 back on and the speed still working without any internet drops.

So for me, I don't really know what went wrong. For your info I did factory reset before all these.

Anyway, I still not sure, the problem might come back later, will report back if it does.

Thanks

Im having this problem too and in my case is pretty hard to track since it may happend a few times in one day or none. But when it happened i was sure that the problem was the router and not the ISP.

Im using the last firmware and the device is V5, another thing to add is that in the firmware that came as stock when this happened every web i tried to load it said something like "WAN Unplugged" with the TP Link logo.

These drops only last for 4/5 sec in my case and then it starts working again.

@Basj C7 is a big #$%...

I'm return it to the vendor today... 

TP-link suport, is the same...

@Basj, I'm wondering if the problem returned or not... I'm facing the same issue since I bought that router and didn't find any solution on the internet to now.
