R7000 and static addresses

R7000 and static addresses

I've set up 5 static addresses on my R7000.  Three are a Synology NAS, an Epson Printer, and an R6050.  All three work perfectly.  The other 2?  Nope.  I've found I can go to my browser and type in all 5 IP addresses.  Only the R6060 connects.  The other four give "This site can’t be reached."  Genie Network map find none of the 5.

 

In the router's web page, ADVANCED>LAN setup, all 5 devices show.  In Netgear Genie only the Epson printer shows, but it's grayed out and shows "Offline."  How do I gain access to these devices?

   Not really.  A static address is configured on the device itself.
Presumably, what you did was reserve some dynamic addresses (in the DHCP
server) on your R7000.  (ADVANCED > Setup > LAN Setup : Address
Reservation?)  As usual, showing actual actions with their actual
results (error messages, LED indicators, ...) can be more helpful than
vague descriptions or interpretations.

   Define "work perfectly"?  Doing what, exactly?

 

> [...] The other 2? Nope. [...]


   "Nope" is not a useful problem description.  It does not say what you
did.  It does not say what happened when you did it.  See "As usual,
[...]", above.

 

   For a start, what are the IP addresses which you reserved for these
devices?  Do they appear in a BASIC > Attached Devices report on the
R7000?  (At which IP addresses?)

 

   Both an R7000 and an R6050 are, by default, routers.  Cascading
multiple routers can cause multiple problems.  How are all these devices
connected?  What, exactly, is connected to what?  Hint: If a device has
multiple Ethernet ports, then "connected to device" is not enough
detail.

 

> [...] R6050 [...] R6060 [...]

 

   R6050?  Why are you using the R6050?  Did you leave the R6050
configured as a router, or did you configure it as a wireless access
point?  (Which might make more sense.)

 

> In the router's web page, ADVANCED>LAN setup, all 5 devices show.
> [...]

 

   Those are your (dynamic) address reservations.  That report tells you
nothing about what's actually connected.  You could reserve an address
there for an IBM mainframe computer, but that wouldn't give you a
connection to one.

 

> In Netgear Genie [...]

 

   Is that some app?  I'd stick with a web browser.

 

   Knowing nothing about how all this stuff is connected or configured,
it's tough to be confident in specific advice, but if the R6050 was
intended to extend the wireless-network coverage of your R7000, then
you'd probably want to configure the R6050 as a wireless access point.
Otherwise, with two routers, you'd get two different LAN subnets with
different LAN IP address ranges, and you could expect connectivity
problems between them.

 

   Assuming that the R7000 is your main router, connected to your ISP
through some (unspecified) modem (or similar device), visit
http://netgear.com/support , put in your model number ("R6050"), and
look for Documentation.  Get the User Manual.  Look for "Use the Router
as a Wireless Access Point".

Re: R7000 and static addresses

You did not configure static ip address. You did LAN IP reservation. These devices should get the IP address that you reserved though. One thing that you could do to make sure that you have connection to these devices is by pinging them.

   True, _if_ these devices are connected to the R7000 where you
reserved the addresses for them.  If they're connected to some other
router, like, say, your R6050-as-router, then they'd get their addresses
from the DHCP server on the R6050, not from the one on the R7000, where
you made the reservations.

   Why didn't I think to mention that?  Oh, wait...

   Apparently.  Actually, praise from someone who parrots some good

Re: R7000 and static addresses

Let's do it this way.  I have an R6050 calbed to my router as an AP.  NAS cabled to the AP.  A TV cabled to the AP.  I'm ASSUMING the router can 'find' the AP since the TV can connect to my network and the TV can be controlled by the app on my S8.

I have an Epson printer and a laptop connected to the router wirelessly.  Both seem to work inside the network.

None of the 5 show up in Netgear Genie.  I can't call any of the 5 up by using my browser

and entering 192.168.1.x in the address bar.  Don't know how to ping.

BASIC > Attached Devices - I have a list of 9 devices.  None of the 5 show, BUT 6 of those 9 devices have "--" for 'Device Name' and I haven't had time to check each MAC.

For now, that's all I have.

I'm interested in your qualification about (dynamic) address reservations.  So I have the addresses reserved.  How do I attach the actual device to the reserved address?  The 6050, for example, has a reserved address, seems to work as it should, but doesn't appear in the "Attached devices" list, nor does it appear in Genie.  It apparently has an IP address somewhere or the router couldn't access it, right?

   What, exactly, does "[cabled] to my router as an AP" mean to you?

 

> [...] What, exactly, is connected to what? Hint: If a device has

   Which part of that was unclear?

 

   Did you also _configure_ the R6050 as a WAP using the method shown at
"Use the Router as a Wireless Access Point" in the User Manual, or what?

Can your wireless devices see all the SSID names for both the R7000
and the R6050?  To which one(s) are you connecting your wireless
devices?

   Still wondering.

 

> [...] None of the 5 show up in Netgear Genie. [...]

 

   Which "Netgear Genie"?  Ever helpful, Netgear uses the name
"Genie" for more than one thing.  Netgear routers have a web-browser
interface called "Genie", and Netgear offers application programs for
various computers/tablets/phones, which are also called "Genie".  (I'd
stick with the web-browser interface.)

 

> [...] I can't call any of the 5 up by using my browser

   Regarding "can't", see "not a useful problem description", above.
"call" from what, your (unspecified) "a laptop connected to the router
wirelessly", or some other device?  "the router" being the R7000?  Where
"x" is what, exactly?  And, again, what's the IP address of this "a
laptop"?

 

> [...] Don't know how to ping. [...]

 

   Assuming that your (unspecified) "a laptop" runs some version of
Windows, open a CMD.EXE ("Command Prompt") window, and type into it a
command like, say:

 

      ping 192.168.1.1

 

A Web search should find more details, if needed.

 

> [...] BASIC > Attached Devices - I have a list of 9 devices. [...]


   With my weak psychic powers, I can't see any of them from here.
Copy+paste is your friend.  And, again, what're all the IP addresses in
this report?

 

> [...] So I have the addresses reserved. How do I attach the actual

   When a DHCP client device gets connected to your LAN, it broadcasts a
request (DHCPDISCOVER), which requests information from any DHCP server
which might be listening.  That request includes the client's own MAC
address.  When a DHCP server (like the one in your R7000) receives such
a request, it replies with (among other things) an IP address for the
client device to use.

 

   An address reservation correlates an IP address and a MAC address (a
reliable property of the network interface of a client device).


   Without an address reservation, when the DHCP server gets such a
request, it will offer any available IP address from its pool of
available addresses.  _With_ an address reservation, when the DHCP
server gets a request from a device with a MAC address which is in its
address-reservation list, it will offer the specific IP address which is
associated with that client's MAC address.

 

   So, a reserved address is still a dynamic (not static) address, but,
for any particular client device, it's fixed/reliable.  And once you've
specified the reservation, the DHCP server should do all the work.

 

   In this case, you configure the R6050 as a WAP to disable its own
DHCP server, and to persuade it to use the same IP address subnet as
your main router.  If you just cascade two routers (acting as
full-function routers), then each one will use its own separate subnet,
and client devices connected to one of the routers will have trouble
communicating with client devices connected to the other router.


   Note that when the R6050 is configured as a WAP, it will normally get
a new/different LAN IP address from the (DHCP server in the) main router
(your R7000), and it should appear in the "Attached Devices" report on
that main router (where you can see what its new/different LAN IP
address is).


> [...] It apparently has an IP address somewhere or the router couldn't
> access it, right?

 

   Every device which communicates on your LAN must have an IP address.
And if anyone other than you could see any of them, then we might make a
little more progress.

 

   I know approximately nothing about your (unspecified) "a Synology
NAS" or your (unspecified) "an Epson Printer", so I can't offer specific
advice, but some NAS devices have a little display which can be coaxed
into displaying the devices network parameters, and some printers can be
coaxed into displaying them, or printing a test page which includes
them.  This sort of feature could be helpful if the device in question
doesn't appear in anyone's "Attached Devices" report.

Please ignore this if you've already done this:

 

The old devices could be holding on to their old IP addresses and won't renew them until their leases expire.  Assuming your devices are configured for DHCP,  a reboot or power cycle will often help.

 

Just an experiment, try to reboot one of the Synology NAS.  If it shows up, then reboot the remaining ones.

Re: R7000 and static addresses

Thanks for the reply.  I've searched here and Google.  One of the 1st tips was reboot devices.  Tried that.  No help.  I've learned a little.  Using my PC - connected to the R7000 wirelessly - I can connect by the standalone Genie app or log in to the Genie app through my browser.  On the standalone app, the Netgear network shows 24 devices.  On the browser, Lan setup shows 5.  Attached Devices shows 9.  I have an ap on my android phone (Fing) that can find 12. Is there anywhere I can get an accurate account of devices my router can access? FWIW, I have 2PCs, 2 cells, one tablet, one laptop, 7 security cameras, one doorbell, 3 light switches, one NAS, 1 printer, 2 TVs, one DTV box, R6050 (AP), and a few other devices linked to my router.  I can control all but a few from their resepctive apps, but most don't appear on the netgear app/web page.  Is there anywhere on the router web page that will show all connected devices, IPs/MACs for each?  I can't access the R6050 to determine it's settings, but it's worked quite well as an AP for over a year.

 

I've used my wireless W8 PC to Ping all devices - well, all IPs from 192.168.1.1 through 192.168.1.40.  I get a successful ping on the router, the NAS, and nothing else.  The Epson printer, for example, shows an ip of 192.168.1.7 on it's screen.  I can print to it from every print-capable device.  BUT, the ping fails and it doesn't show on the Genie app/web page.  It does show on Fing with the 192.168.1.7 IP.

 

Is there a CMD that will return a MAC/IP.  Yes, I know, pings fail, but I hope there is SOME way to find why connected devices aren't found in either Genie.

Re: R7000 and static addresses

If you have an iOS or Android device, try the application "Fing" to see all devices on your LAN and their MAC addresses and other details too

Re: R7000 and static addresses

I'm confused by Fing (android).  It lists 12 of my devices.  But, when I ping them in Fing, it can find none.

On my wireless PC (W8), Netgear Genie (the web page) lists 9 devices.  Pinging them using GetMac shows 2 - the router and the wireless PC.

Genie - the W8 app - lists 23 devices.  18 are "offline"

Yet, I can access all my devices using the device specific app or Smartthings app. OK, not all of them.  Nothing I try can access the R6050 (AP) or the NAS (cabled to the R6050).  I CAN connect to the TV cabled to the R6050.

Re: R7000 and static addresses

I should add the device IPs on Fing do not always match the device IPs on either Genie - app or web page.

Message 13 of 14

Re: R7000 and static addresses

I can add a little.  DLd and installed the Netgear Prosafe app.  It finds the R6050 at the static address IP I assigned.  The W8 Genie app finds it on Network Map at the assigned IP.  The W8 Genie web page DOESN'T find the R6050 at the assigned static address or any other IP.

I can access the DireTV box connected to the R6050 by cable.  I cannot access the NAS connected by cable.  Have I made progress?
