I am trying to enable 2 VAP guest networks on the same radio. I am able to see the first VAP broadcasting, but not the 2nd one.

Router Model: Netgear R8000
Firmware: v3.0-r49197 std (06/14/22)

I have created 2 VAPs wl0.1 and wl0.2. The setup for both VAPs is very similar.

I can only see "ddwrt_vap1" (wl0.1) broadcasting though. The other one "ddwrt_vap2" doesn't seem to even broadcast, no matter how I change the settings.

Is there a limit on how many VAPs one radio can support?

There is a maximum and it is 4 (it depends on router model/chipset)

First your settings are not optimal, use AC/N and never use autochannel just pick a channel ther is a sticky in this forum for the best wireless settings

I think the R8000 is one of the routers with DHD bus, there has been some work done recently on that so it might help to upgrade to the latest build 49418, reset to defaults and rebuild from scratch.

But it is quite possible that the DHD bus is restricting the use of VAP's

Attached how I setup VAP's, for regular Broadcom Arm (the non DHD) it is no problem to have more than one VAP

As always after setting up reboot Smile

Edit: it is strange that the VAP's have the same MAC address that should not be the case.

Edit2: sorry bad monitor, 68 and 6B are not the same Sad

The dhd drivers updates were for the 5Ghz radio to fix some inability to create a VAP on the R7000P, this was due to the 2.4Ghz radio driver assigning wl0 and dhd also assigned wl0 to the 5Ghz radio so weirdness ensued.

There were indeed many other mixed fixes, so it is always worth upgrading after these fixes.

egc is correct and to reinforce his statements, the best settings are documented here and never choose auto as a channel.

To pick the right channel however, its best to analyze the current channels in use in order to pick the best suited see https://vremsoftwaredevelopment.github.io/WiFiAnalyzer/

On a sideways note, my router RT-AC68U supports up to 16 VAPS, I've not tried setting up more than one per radio. I think it says it on the page how many are supported, i didnt see it on your screenshot, it does on mine see attachment. (I think its quite useful to say it)

Apologies for jumping in Wink

Thank you both.

I am not able to update to 49418 just yet - I will in a few hours and come back

Meanwhile, I did change the settings as per the Sticky (which I was going to do, once I got the VAPs working)

I don't have any channels listed other than Auto Sad (See screenshot)
Maybe that's another red flag

My screenshot shows Max Vaps(4). I don't have any other VAPs other than the 2 that I was trying to create

Hmm that does not seem OK indeed.

You might toggle the settings e.g. set 20 Mhz, Save and the Apply toggle upper/lower, that sometimes helps.

But the newer firmware should have more channels available on 5 GHz so maybe upgrade and after that reset is certainly an option

The channel choices will become available after you select the ACN and click save (not Apply)

But wait until after the upgrade. And when you're done , dont use DD-WRT as your SSID, anything that is not identifiable to you or the router or what you're running is better.

SSID doesn't matter but identifiable information is best left out, some ppl know that some things have specific flaws and may try exploit specifics. Misdirection is always nice.

Select channel width, save.
Select valid extension channel, save.
The valid list of channels should appear.

This may be tied to the dhd driver issue that affected the R7000P, so upgrading first may be necessary, as @egc stated. Luckily, this is not like the RT-AC87U with the Quantenna hardware involved.
