GS308v2 devices no LAN through new Nighthawk R8000

Hi all,

I'm new here. Just installed an R8000 router but the devices on my older GS308v2 switch don't appear to be seeing the LAN or WAN.  Lights on the GS308 all appear normal. 

The devices on the switch normally are things like a weather station hub, a web cam, a D-link AP (part of a security system) and a NAS.

If I connect a Win10 laptop to the switch is sees the connection as "unnamed network, no internet". 

Can someone please point me in the diection of any troubleshooting  procedures for something like this?  I'm not even sure if I should be searching or looking for issues with the router or the switch.

Thanks in advance for any help.

   Why?  Replacing what?

 

   "installed" could mean almost anything.  What, exactly, did you
connect to what, exactly?  (Hint: If a device has different types of
Ethernet ports, then "connected to device" is not enough detail.)

   Which "Lights on the GS308"?  Defne "normal".  What about the lights
(or anything else) on the R8000?  Or on any other gizmos in the chain
(like, say, a modem)?

 

   Visit http://netgear.com/support , put in your (router) model number,
and look for Documentation.  Get the User Manual (at least).  Read.
Look for the LED descriptions and "Troubleshoot".

   Same here, but I'd bet on the router.  But why guess?  Run the
experiment.  What happens if you connect a computer directly to the
R8000, without involving the (almost fool-proof) switch?

I spent an hour doing a detailed reply and got an authentication error when I clicked POST.  

 

I'll try to reply with details again tomorrow.

Thanks for the reply.

 

I bought an R8000 router to replace an older DD-WRT Buffalo that had twice required a power cycle in the last month. It appeared to be unresponsive with no LEDs except the POWER LED.  Cycled power and it worked fine until the next time.  

 

By ”installed” I meant that I removed it from the box, connected the AC power cord, moved the ethernet cables from the Buffalo ports to the R8000 equivalent port numbers as well as the ethernet from the modem. And plugged the R8000 into an AC outlet.

 

The Modem is provided by the cable company and is a Cisco DCP3008.

 

About the LEDs:

  • Cisco DCP3008
    • POWER on green
    • DS on green
    • US on green
    • ONLINE on green
    • LINK flicker green
  • GS308
    • POWER on green
    • Port 1-8 LEDs are flickering green wherever an ethernet is connected
  • R8000
    • POWER on white
    • INTERNET flicker white
    • 2.4ghz flicker white
    • 5ghz 1 flicker white
    • 5ghz 2 flicker white
    • USB 3.0 off
    • USB 2.0 off
    • 1 flicker fast white WD NAS
    • 2 flicker slow white (weather station hub)
    • 3 off (empty port)
    • 4 flicker slow RED (GS308v2)
    • WIFI on white
    • WPS on white

 

Ethernet connected to the GS308 are:

  • Dlink router  (installed years ago by security company as a wifi access point for their equipment)
  • WD backup hard drive
  • Dlink webcam

Prior to creating a community account and asking my question here (and wasting your precious time) I had already visited  http://netgear.com/support , put in my (router) model number, and downloaded all documentation.  I’ve read the User Manual (at least).  Checked the section on LED descriptions and found no reference to a RED LED.  

 

In the “Troubleshoot” section I found nothing similar to the symptoms I’m seeing.

 

I have connected a laptop to the router directly in all 4 ethernet ports and both the LAN and WAN appear normal. 

 

Also of note, when I move the GS308 to a different router port, the RED LED follows. 

The GS308 is connected to the R8000 with Cat 5e in switch port 1.  I could find no documentation on the unmanaged switch indicating which port should connect to the router.

 

What do you mean “Run the experiment”?   Are you suggesting, as an experiment, that I connect a computer directly to the router? Done that.  All good.

   If you connected the modem to the R8000 WAN/Internet port, and the
client devices to the R8000 LAN ports, then you should be ok.

   Is your "RED" what Netgear calls "amber"?

 

   From what I can find on the GS308v2, it does not indicate port speed,
only connection and activity, so it's less than ideally helpful.  A bad
Ethernet cable (less than eight good conductors) could give you a
sub-gigabit link rate, which the R8000 should show as "amber".  (As the
R8000 User Manual says.)

   Where "normal" is how you spell "white"?  So, the R8000 (including
all its LAN ports) works as expected?

   Try a different cable?

 

   If your "RED" really is red (not amber), then you'd seem to have a
problem with the cable or the GS308v2.  (And/or the R8000
documentation.)

 

> [...] I could find no documentation on the unmanaged switch indicating

   The switch ports should all be equivalent; connect any one of them to
a router LAN port.


   There really doesn't seem to be enough stuff here to create a real
mystery.  You seem to have proven that the R8000 and at least one of
your client devices are ok.  If the R8000-to-GS308v2 link is bad, then
that would point to the cable or the switch.  Swap the cable with a
known-good cable.

 

   For a quick cable test, connect each end to a LAN Ethernet port on
your router, and observe the relevant port-status LED indicators.  For a
good cable, both port-status LEDs should indicate a maximum-speed
connection.  (And they should agree.)  If a known-good cable does any
less, then I'd suspect the router hardware.

Thanks for the suggestions.  You've given me a few things to consider.
