D6000v2 in AP Mode - Wifi devices not able to access network

[subi751]

On my home network, historically I was using a D6000v2 as the main router, with 2 x R6220's in AP mode, connected to the D6000v2 via ethernet on their LAN ports, all sharing the same SSID and pwds to spread out my home wifi.

Due to issues with the D6000v2 locking up, I've since replaced it as the main router with another brand's non-wifi router. and reconfigured the D6000v2 to be in AP Mode to retain the ability to use it as an AP in its existing location.

However, since converting it to AP Mode, any wifi devices (Android and Apple phones and tablets, Windows based laptops, etc) connecting to it reported no network connection.

The firmware was originally 1.0.0.62, which I have since upgraded to v1.0.0.66 but that has not resolved the issue.

Performing a factory reset of the D6000v2, and doing a manual setup directly in AP Mode has not resolved the issue.

Additionally I have physcally swapped the D6000v2 with one of the existing R6220s and the R6220 is fine, I can connect with the R6220 without issue. The same applies for the other R6220.

With the D6000v2 in the location where one of the R6220's originally was, the D6000v2 still has the same issue. Note - when relocation I physically only swapped the routers and their power supplies. existing ethernet cables and original LAN port on the non-NetGear router for that ethernet cable have not been touched/changed/replaced.

I also have an IP camera (ethernet connection, not wifi) connected to one of the LAN ports on the D6000v2, and that is accessible over the network via either ethernet connectivity or wifi via the R6220's but cannot be accessed if connected to the D6000v2's wifi.

Recently I've also noted that the issue primarily occurs if connected to the D6000v2's 5Ghz band whilst its 2.4Ghz band appears to be randomly working ok.

Given all my debugging to date, I believe this is an issue with the D6000v2 in AP Mode, it is not an issue with the rest of my network given the R6220's work fiine and I have not had to touch them at all

Has anyone come across this issue before with the D6000v2 and know of a fix, short of replacing the unit?

It could be just me, but I can't follow what is going on here.

First, the D6000v2 is a modem/router, not just a router.

Second, we don't know what you mean by "another brand's non-wifi router". I would expect a modem of some sort to to replace the D6000v2, not a router.

And a "non-wifi router" would normally describe  a modem only device that doesn't operate as a router. In which case, you would need the D6000v2  to work as your router, not an AP.

You could clear things up a bit by telling people what this other brand's non-wifi router is.

Fair call, yes the D6000v2 a modem/router

The other "non-wifi router " is a Ubiquiti Unifi USG, which is a (using correct terminology) a modem/router, but does not have an inbuild Wifi AP, hence why I called it a "non-wifi router"

In the hope of trying to clarify my network, in a badly drawn high level overview, I've attached a picture of the setup as it was, and as it is now . The green line is the seperation between the scenarios, red line is the incoming broadband line, blue lines are my internal ethernet network between the USG (and a new Unifi switch) and the Netgear modem-routers (all the Netgears are operationing in AP Mode in the current setup, originally only the R6220's were in AP Mode). The pink line is an ethernet cable to the IP camera.

That is more a label than a model number but Google suggests that it is some sort of "gateway".

This?

Ubiquiti UniFi Security Gateway Router (USG)

But it isn't a DSL modem/router. Maybe you weren't using the modem bit of the D6000v2. 

I think I follow the diagram, but I don't understand the absence of any modem in the new setup.

Are you sure that the D6000v2 is in AP mode?

I can't find that model in Netgear's database, but the manual for the original D6000 lacks the usual instructions on turning it into an AP.

Remember to use the correct WAN port on the D6000.

   How, exactly?  As noted above, the D6000 User Manual doesn't mention
a WAP-mode option.  I see no D6000v2 documents; does "v2" add that
feature?  If not, then configuring the D6000v2 as a WAP should be
possible, but would be more complicated.  See, for example:

      https://community.netgear.com/t5/x/x/m-p/1463500

That's written for a Netgear C6300-as-WAP, but the steps are about the
same for any other router (any make/model) which lacks a one-step WAP
option.

   It made sense to me.

Apologies... my problematic modem/router is NOT a D6000v2, its a D7000v2 (minor typo in name) -

https://www.netgear.com/support/product/D7000v2.aspx

As for the USG, regardless of the information on the internet you have read, it is a modem/router. If you want to read up on it, refer to https://help.ui.com/hc/en-us/articles/236281367-UniFi-USG-How-to-Adopt-a-USG-into-an-Existing-Networ....

The very first description sentence on that page is exactly what I have done with the USG replacing the D7000v2. In respect to the diagram on that page about "Planning the Deployment and Establishing Internet Connectivity", the referenced "ISP Modem Router in Bridged Mode" for me is a Netcomm NDD-0300, which the D7000v2 was connected to before I purchased and replaced it with the USG as my network's central modem/router.

To fully describe my internet connection from the external copper phone line, the phone line is connected to a NetComm NDD-0300.

The Yellow "Gateway" ethernet port on the NDD-0300 is connected via ethernet cable to the Gateway (aka WAN) port of the USG. Before purchasing the USG, the NDD-0300 was directly connected to the EthernetWAN port of the D7000v2 via the same method (refer https://www.downloads.netgear.com/files/GDC/D7000v2/D7000v2_UM_EN.pdf, page 140 for how one of the ethernet LAN ports can be reconfigured to be a WAN port).

One of the USG's LAN ports is connected to the USG switch I am using. The other USG LAN port is not in use.

The USG Switch is connected to the 2 x R6220's on their LAN ports, and to the D7000v2, also on its LAN port.

I AM NOT currently using the EthernetWAN port of the D7000v2 (remember, I have done a factory reset of it, which reset the EthernetWAN port back to LAN mode, and then configured it in AP Mode, effectively disabling all WAN/DSL connectivity). The D7000v2 is now used as a local switch and wifi AP, and therefore it is currently connected to my network via one of its LAN ports, exactly the same way the R6220's are connected to my network.

Attached is a screenshot taken from the D7000v2's config page, showing that its in AP Mode, and how that works on the network, and is exactly how I have it setup currently.

Note - If the USG was not a modem/router, then I would not be connected to the internet right now typing this as that is the central device my entire network goes through to then connect to the NDD-0300, and in turn access the internet.

Getting back to the issue at hand, the D7000v2 (not D6000v2) is in AP Mode, but devices connecting to it via its Wifi AP (primarily the 5Ghz AP) cannot communicate with the rest of my network. As stated, I have the D7000v2 connected to my network via ethernet on one of its LAN ports, and I have an IP Camera also connected via ethernet directly to the D7000v2, and the IP Camera is accessible from the rest of my network, but not via the D7000v'2 Wifi APs. Therefore, there appears to be an issue with the D7000v2 when in AP Mode not allowing Wifi devices to access the rest of network.

   That matters.

   Which you think had _no_ effect on that "LAN 4 / Ehernet WAN" port?

> [...] effectively disabling all WAN/DSL connectivity).

   Says who?

   That could be the problem.  On a Netgear (modem+)router with a
WAP-mode option, you _should_ be using its WAN/Internet port for the
connection to the main router.  The artwork in the (generally poor)
D7000v2 documentation may be less than clear/explicit about this.

   Does that mean that you didn't follow the instructions for WAP mode
in the R6220 User Manual (either?)?

      > To set up the router as an AP:
        1. Use an Ethernet cable to connect the Internet port of this
           router to a LAN port in the other router.

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

   D7000v2 firmware tends to be more buggy than most, but following the
instructions in the documentation might help some.

It may be a "minor typo" at your end. For me it wasted time. Thanks.

   More than pointless quibbling about "router" v. "modem/router"?
