Google nest router LAN port not working

[beno]

Hi, lots of people reporting this, but non seem to have this resolved. I run modem to google router WAN port, then LAN to TP link 8 port unmanaged switch. 

The internet will not share either through the switch, or when directly connected to the LAN port. Interestingly, I can connect to my mycloud hard drive through the LAN port (and switch).

Trying to hard wire some products to the router. Have done all the factory resets etc and spoke to google live chat, who escalated it to senior technical support. Then have heard nothing.  Can anyone confirm they actually have got it working?

Thanks,

Ben

So I just got my Nest 2200 today and spent 2 hours on the phone trying to get it up and running. once it was finally up and running I tested my computer which is hard lined in through an 8 port NETGEAR switch unmanaged and I was only able to pull 90 megabytes on my upload and download when I pay for a gig through spectrum and when I went and did a speed test on my phone through the app I was able to pull 600 which makes no sense at all. once I got off the phone with the technician I troubleshooted with three different one gig switches and I still cannot get over 90 mb on my download on any of my hard line devices.

Did you try different cables too? Capped to close to 100mbps is often caused by faulty equipment.

[olavrb]

What exact switch?

[EpicPHEONIX114]

2 different trend net 48 ports and a standard netgear 8 port. I tested 2 cables going straight into the nest to my pc and got up to 300mbs once I introduced a switch it will not go above 90mbs

[olavrb]

What exact switches? Model number and all.

Reason I ask is that even unmanaged switches can have features that could cause this. Most relevant is loop detection/prevention, like STP (spanning tree protocol).

[EpicPHEONIX114]

Teg-2248ws is the model number. But I had no issues with it on the old spectrum router. That's all I switch out was spectrums router for the nest router and now having the lan speed issues. 

[olavrb]

Two observations on Trendnet Teg-2248ws relevant to Nest Wifi:

• https://www.trendnet.com/products/product-detail?prod=205_teg-2248ws

1. Most of the ports is 10/100, not gigabit (10/100/1000). If you are using the gigabit ports, maybe the switch does not auto negotiate using gigabit with Nest Wifi. Maybe you can override this, so that the switch uses gigabit?

2. It has STP. See following URLs on why it must be disabled on the switch:

I went in and I have a gig on all ports. It just seems that any other articles I've read once the switch is introduced to the system it limits the hard lined connections 

[beno]

My switch is a TL-SG108S, but even if I plug into the LAN port directly with a laptop, it didn't work. And yes, I've tried different cables. Strangely, it will detect the hard drive and allow me to access that through the LAN port, but it won't share the internet connection

[olavrb]

The switch should work.

Have you tried different cables? Some have had problems with CAT6a cables, likely because of their stifness vs. Nest Wifi tight cable routing. So try some flexible CAT5e if you can.

Have you inspected all the RJ-45 ports in case any of them are defective? Bent pins etc. I've read that this has caused issues like this previously.

[EpicPHEONIX114]

I've tried 4 new cables. Verified they aren't broken pins with a tester. If I go straight from the hub to my pc I get the 300 to 600 speed. Take that same cable and go into the switch I cannot get 100mbs on the switch. Most confusing thing I've ever ran into. 

[beno]

Yep,

Have tried different cables - they don't work or light up the port to show a connection. It does connect to the hard drive locally through both the LAN port and the switch (through every port) with all the cables I have, so it can't be the hardware side of things I think.

Is there an issue passing through the internet connection that needs a software setting?

Thanks,

Ben

[olavrb]

It (the LAN port) should just work, and give internet access.

I've escalated this thread, hopefully Google will reach out and troubleshoot further.

[beno]

Thanks olavrb - much appreciated.

I'll await Google's response

Hi Abi,

It is not resolved. Any help you could give would be great. I've raised it with Google directly (Case ID 4-5419000033460), but have heard nothing back at all.
