Abnormal delay in pinging the gateway ip through WAN 2.5G port.
Hello
When my SXR80 WAN 2.5G port is connected to the ISP's gateway, the computer is connected to the LAN through the cable, and then the latency is very unstable when pinging the ISP's gateway ip on the computer, however, this problem is solved when I set the WAN port in the WAN settings to port2 (1G), and I tried to use a NETGEAR R7000 as an uplink DHCP gateway. then the problem does not occur.
Test process: R7000 as DHCP gateway, SXR80's WAN 2.5G port is connected to R7000's LAN port, at this time, the computer is connected to SXR80's LAN port, and then ping the R7000's management ip on the computer.
So the conclusion is that there is a hardware failure in the WAN 2.5G port of SXR80, or a router software problem.
Since I live in China, I contacted China Netgear tech support and they told me that they did the same test as me and the result was that they were unable to reproduce the problem and concluded that it was a WAN 2.5G port failure.
Since I ordered from Amazon China in Amazon USA, Netgear China rejected my warranty request, and Amazon USA could not assist me with my order warranty because of the different login account, even though I have the order number from Amazon USA, so please tell me how I can proceed with the hardware warranty, which should be until November 2026 through Netgear's official website.
case number: 48171868

Re: Abnormal delay in pinging the gateway ip through WAN 2.5G port.
If you bought it from Amazon US you have contract with Amazon US.
Assuming the device was properly registered, it's registered with Netgear as a US device, in a US location. Device return goes on your expenses, and exchange shipment can go only to an US address, they won't ship it abroad.
Where you live or where you have exported the device to is your own personal choice.
One additional reason is that you have exported an FCC regulatory device to abroad, FCC regulations (not Netgear!) don't permit to change the radio config to other regulations, so you are operating a device illegal to operate in China mainland.
FMI https://en.wikipedia.org/wiki/List_of_WLAN_channels
I doubt you can order a US device from Amazon China. Sure, Amazon has (or had) a very poor customer information policy and does not correctly inform their customers, they often allow shipping ways beyond of what is allowed. Yes, Amazon e.g. US does typically not care if the customer is ordering for shipping to an address abroad, so Amazon does (or did) often allow to ship FCC regulatory devices to addresses abroad, handing over the full risk and responsibility for the import to the receiver. It does not matter if Amazon does handle the shipping to abroad: You are the buyer, and become the importer for the destination address.
By far not a lawyer on trading and importing, however: In brief, this is what applies for self-importing radio equipment into Switzerland (and more generic into Euro.... First hurdle will be the lack of CE mark on the FCC devices 8-)

Re: Abnormal delay in pinging the gateway ip through WAN 2.5G port.
Hello @schumaku
1. How do I find out where my device is registered?
2. According to the official website, my device was purchased on December 1, 2021, so can I apply for an exchange now?
3. I can ship my device from abroad to a designated US address, but I can only ship an exchange device to the US, right?

Re: Abnormal delay in pinging the gateway ip through WAN 2.5G port.
Whatever is the "official Web site" for you.
What shows https://my.netgear.com/ exactly?
Please challenge Netgear, I have -no- idea what should be specific for the Chinese mainland market when it comes to the product registrations.

Re: Abnormal delay in pinging the gateway ip through WAN 2.5G port.
By official website I mean “https://my.netgear.com“
The website sees that I registered this product and shows when it was purchased and when it was registered, and that's all.
Now China Netware thinks I didn't buy it from mainland China and there's no invoice, and wants me to contact Amazon, Amazon USA wants me to contact China Amazon because I placed the order using a China Amazon account, and China Amazon wants me to contact China Netware to deal with it.

Re: Abnormal delay in pinging the gateway ip through WAN 2.5G port.
As I'm no no aspect Netgear, only Netgear (and Amazon) can deal with this. As you have an order number from Amazon US (and an order confirmation) my -guess- is that you have received a US/FCC model. Netgear can certainly check this. As well, if my assumption is correct and you received an FCC version (read a US version) this should be visible based on the available channels for the 5 GHz band (about 96...144) which are prohibited in China mainland, along with the channels 12 and 13 which are typically not available on FCC models.
Convinced @Nivedita should be able to check this for you.
Ref. the higher latency to your 192.168.1.1 address (best guess this is the SXR80 LAN IP address): Is there also an SXS80 (Orbi Pro Wi-Fi 6 satellite) in the game and data path? As this might be wireless (if having it deployed as wireless Mesh, so s wireless backhaul, no wired backhaul) higher latency is well possible.

Re: Abnormal delay in pinging the gateway ip through WAN 2.5G port.
I'm sorry maybe I misdescribed it, 192.168.1.1 is the ISP's gateway address and the SXR80 is working on the 10.0.0.0 network segment.
The problem I'm having is that the WAN port of the SXR80 is connected to the ISP's gateway, and the computer is connected to the SXR80 LAN port, and pinging the ISP's gateway on the computer has a delay of several hundred or several thousand milliseconds.
But when I set the WAN port of the SXR80 to port2(1G), this problem no longer occurs.
Also have submitted case to China Netgear tech support, 48171868, but they tested it and thought it was a WAN port hardware failure.
However, I found that none of the uplinked gateways have STP settings, so I can't rule out an STP issue, but I can't disable it to do the test, and I can't see the ping latency data in wireshark, and it doesn't seem to affect my internet access.

I have performed three scenarios of getting logs, using the R7000 as a gateway, and ISP gateway, and setting the WAN of the SXR80 to port2(1G), where when connecting to the R7000 and the ISP gateway, after each reset or reboot of the SXR80, sometimes the ping will be delayed and sometimes it won't.

Re: Abnormal delay in pinging the gateway ip through WAN 2.5G port.
Hello @schumaku @Nivedita @BasuKhodanapur
The hardware replacement of the device has been completed, however, the problem still exists on the newly replaced device, which means that the cause of the problem can be basically ruled out as hardware.
Previously, based on case number 48171868, the Chinese tech support had escalated the case to the US R&D at my request, and the feedback was that there was a hardware problem, and that's why the device was replaced, which is obviously wrong, so we should correct this mistake, but I'm not sure how to contact the US development team.
At present, the Chinese technical support think they can't reproduce this problem in the lab environment, insisting that it is my network environment, but can't tell me the specific reason, according to the test will be set to WAN port 2 (1G) when this problem can be solved, which means that the WAN port 1 (2.5G) and port 2 (1G) different configurations is the key to solving the problem.
The other difference between the test environments is that they are using the R7000P uplink device, and I am using the R7000.
So can someone please help me to solve this problem completely, thanks.

Re: Abnormal delay in pinging the gateway ip through WAN 2.5G port.
What is the Mfr and model# of the Internet Service Providers modem/ONT the NG router is connected too?
Be sure your using a good quality LAN cable between the modem and router. CAT6A STP is recommended.

Re: Abnormal delay in pinging the gateway ip through WAN 2.5G port.
Hello @FURRYe38
I used CAT6A cable and the problem persists.
The ISP modem is a ZTE, model ZXHN-F4600T.
Also have a Netgear R7000 as an uplink gateway with the same problem.
However only the 2.5G port is experiencing problems.

Re: Abnormal delay in pinging the gateway ip through WAN 2.5G port.
Both the R7000 as well as the ZTE ZXHN-F4600T have only GbE interfaces, no MultiGig or 2.5 GbE capable. Does the SXR show a GbE link speed on that SXR 2.5G WAN interface?

Re: Abnormal delay in pinging the gateway ip through WAN 2.5G port.
What mode is the ISP gateway working in? Router or has it been bridged?
What CAT# LAN cable are you using between the ISP Gateway and the SXR router? CAT6A STP would be recommended when connecting on 2.5Gb ports.
Any chance you can test the SXR at a different location with a different ISP modem or gateway to see if problem follows?

Re: Abnormal delay in pinging the gateway ip through WAN 2.5G port.
Hello @schumaku
I don't understand what it means to show GbE link speed on the SXR 2.5G WAN interface.
Does it mean selecting port 1 (2.5G) or port2 (1G) in the WAN settings?
What is MultiGig? What does it do? Shouldn't 2.5G interfaces be downward compatible with Gigabit ports in general? thanks.

Re: Abnormal delay in pinging the gateway ip through WAN 2.5G port.
Hello @FURRYe38
The ISP gateway is only allowed to use the router.
The ISP gateway and the SXR router were previously being used with CAT6A LAN cables.
Have tested 2 different ISP gateways and a Netgear R7000 gateway, the problem is the same and the problem occurs on WAN Port1 (2.5G) and is normal when switching to WAN port2 (1G).

Re: Abnormal delay in pinging the gateway ip through WAN 2.5G port.
So the R7000 exhibits the same problem when connected to the ISP gateway?
Are you using the ISP gateways DMZ or IP-pass thru for the SXR router?
So if you select 1Gb on the SXR for the WAN connection, no abnormal delay is seen with the SXR connected to the ISP Gateway?

Re: Abnormal delay in pinging the gateway ip through WAN 2.5G port.
The problem appears while using the 2.5GbE port only, despite technically it is supposed to fall back to a 1 GbE, the problem does not show up on the GbE WAN port - on the very same SXR80 router. No difference which CPE or uplink router is in use. @shejialun described this very clear @FURRYe38 ....
Something behaves different while connecting the MultiGig capabe 2.5 GbE WAN, despite its negotiating to a "simple" GbE port. Could be different flow control, different buffer sizes, ...

Re: Abnormal delay in pinging the gateway ip through WAN 2.5G port.
Hello @FURRYe38

no, There is no ping ISP gateway latency when the R7000 is connected to an ISP gateway.
Are you using the ISP gateways DMZ or IP-pass thru for the SXR router?
All I can say is that whether the SXR80 is connected to the ISP gateway or the R7000, the WAN gets the ip address directly from their DHCP.
So if you select 1Gb on the SXR for the WAN connection, no abnormal delay is seen with the SXR connected to the ISP Gateway?
yes, I have tried to set the WAN of the SXR80 to the port2(1G) interface, no ping ISP gateway latency issues.
When I connect according to this topology diagram, I also get abnormal delays, so this shouldn't be a problem with the ISP gateway or LAN cable, and I purchased this R7000 in July 2014

If the ISP gateway is in router mode, you should be using it's DMZ or IP pass thru for any external router connected to it.
So if you select 1Gb on the SXR for the WAN connection, no abnormal delay is seen with the SXR connected to the ISP Gateway?

Since the connection with the R7000 if you have this in the mix between the ISP router and SXR, you probably should use the 1Gb WAN port connection since the R7000 only has 1Gb WAN/LAN ports.
Something to check with NG about and see if they can help with this. Again, the 80 series is EoL so not sure if there would be any more FW updates to resolve this and the 2.5Gb WAN speed issue. Something to ask them about.

Re: Abnormal delay in pinging the gateway ip through WAN 2.5G port.
Hello @Nivedita
I need help, I purchased my product just under 3 years ago, not even 5 years past the warranty period, I should get an official technical solution from Netgear for a problem like this, it should be my right, otherwise what's the point of our warranty period as users?
So please assist in solving this problem, thank you.
