Not working or now working?

It always helps to use language that people can understand.Only then can people understand what is going on, and weed out user error from a genuine technical problems.

[zouguanmin]

I think it’s not a software problem but a hardware problem. We’ve tried it many times，both work only one day second day is broken

[zouguanmin]

But I really doubt the quality of NETGEAR, since it is broken after upgrading the firmware

[Netduma-Fraser]

If you do the Benchmark test and post the results it will help us determine what exactly the issue could be

[zouguanmin]

Yeah the internet appears fine there. Do any of your devices connected to the router work? On a PC connected to the router open command prompt, type ipconfig and press enter then post the results. Also in the same window type ping 8.8.8.8 -n 10 press enter then post the results.

u mean this test？

[Netduma-Fraser]

Do a Connection Benchmark test please and provide a screenshot of the results - you can find it on the interface.

[zouguanmin]

Nothing coming out

[Netduma-Fraser]

Thanks, can you grab a copy of the log file on the System Information page please?

[Netduma-Fraser]

Are you using IPv6? If so disable that please and see if it works

[zouguanmin]

no i don't use ipv6

[Netduma-Fraser]

What is your ISP modem/router model?

[zouguanmin]

Isp modem

[michaelkenward]

The Arris CM280A (there, it wasn't that hard was it?) is a standard modem-only cable modem. No router to get in the way.

Could have ruled out a lot of questions had you mentioned it, as requested, earlier on.

It dates back to 2011, according to the label. Bit ancient.

I post this picture yesterday, and this isp modem is fine becouse i change other router Internet anything is good, xr700 before i update version is good too, but when i update version xr700 is broken

[Netduma-Fraser]

Okay that won't be it. I think you may have a faulty router if other routers are working with that modem. You could try reupgrading the firmware using TFTP which could help if the issue was in the boot sequence.
