WNDR4500 V2 ping time issue

I previously had a WNDR4500 V1 that died. Since I was using the media server function, I wanted to replace it with the same model. All I could find was the WNDR5400 V2. Setup was nearly identical, but I noticed an odd issue.

My ISP is a WISP. I use a program called AlertPing that pings the ISP's "tower" every so often. That way I know when the link goes down. Prior to the original router dying, ping times to the tower would be around 4ms-8ms. After connecting the V2, those ping times went up to 15ms-20ms. If I bypass the router, they drop back to around 3ms-4ms. so it seemed that something in this router was inducing some extra latency.

I played all of the router settings I could think of, but nothing helped. Then I discovered something else. If I simply ping the V2 router it's self (LAN ports) from a wired computer (even with nothing else connected), I am getting ping times of 1ms-9ms. Of course everything on the LAN should be like 1ms-2ms all the time, so something is causing the higher latency with this router. I tried this with several computers and they all have the same result. For some reason the router has higher ping times than it should, even just to it's self.

It does not seem to be causing any other issues, but I really would like to know if it's normal for the V2, or if there is something wrong with the router. Any suggestions, or can someone else confirm that theirs does the same thing? I have the latest firmware installed. I even rolled it back one version, but it does the same thing.

46 views and nobody can confirm whether or not pings to their V2 LAN ports are more than 1-2ms?

Re: WNDR4500 V2 ping time issue

Ok, I know I am the new guy here, but can someone with a WNDR4500 V2 with a wired computer please ping their router's LAN port a few times and see what it does? If you are getting sub 1ms times, what version firmware are you running? This really has me puzzled and I'm not sure if it's a hardware issue or something else.

Here is what I am getting plugged directly into any port with nothing else connected to the router (tried multiple PCs with the same results).

Re: WNDR4500 V2 ping time issue

I'm having the exact same issue. I have just about everything disabled on the router and it is still giving me 9 ms response times via a hard wire. This feels like a bug to me and I'm very close to returning it...

Re: WNDR4500 V2 ping time issue

Here's another screenshot showing how ping times are all over the place. This is a ping from my computer to the NetGear, which is my default gateway all over CAT5e cabling. There should be zero reason for this high latency in a high bandwidth directly-connected scenario:

Re: WNDR4500 V2 ping time issue

I was able to resolve this issue by switching to a competitor's product.

I still believe this is a bug in the NetGear N900 that the manufacturer needs to address...

Re: WNDR4500 V2 ping time issue

THX,
Thanks for confirming I am not the only one with this issue.

FWIW, I have still been having this issue with those abnormal pings to the router. I really did not want to try doing a hard reset and starting all over because everything seems to work ok except for that and it took me a while to get the USB sharing set up just the way I wanted it. Anyway, just for the heck of it, I picked up a refurb (same model) on ebay for $39 (should have bought it a month ago when they were $29). One has to wonder how some of those sellers can have sold over 900 of these refurbed units. Is Netgear getting that many returned? :eek: Anyway, the refurb I got returns pings <1ms just like it should. I will probably just hold onto that one as a spare for when this one dies.
