Router : R7000
Firmware: DD-WRT v3.0-r31205M kongac (02/03/17)

The physical interface (wl0) is configured as access point with WPA2 PSK. I also set-up a guest SSID as virtual interface (W0.1) with WPA2 PSK. This setup is working without any problems.

Now when i add an additional virtual interface (wl0.2) suddenly wl0 stops broadcasting. wl0.1 and wl0.2 keep on broadcasting.

Now when i again at an additional virtual interface (wl0.3), wl0 and wl0.1 stops broadcasting. Wl0.2 and wl0.3 keep on broadcasting.

Within the DDWRT GUI everything seems to work. The virtual interface are created. But on my laptop i can not select the SSIDs of wl0 and wl0.1 anymore. And also with an app WIFI Analyser on my phone i can see that the signal drops the moment i create an additional virtual interface and push [apply settings].

I restarted the R7000 multiple times but the problem persists.

* Is there somebody with a R7000 that can create two or more virtual interface to test whether this also the case on his/her router?
* Is somebody familiar with this problem and has a solution for it?

Thanks in advance!

Seen your post on Kong's Build Release 32170M.....

I do recall having upto 6 SSID on one router on older Kong Builds, don't recall the build numbers. But in any case, yes I do have 5 SSIDs running without any issues with Kong's Build 32170M, 3 SSIDs on 2.4Ghz and 2 SSIDs on 5Ghz.

Basically I leave most of the wireless setting at Default from an 'erase nvram && reboot'.

Here are my settings....

Regulatory Domain - UNITED_STATES
Regulatory Mode - Off
TPC Mitigation Factor - 0(Off)

Physical Interface wl0 - SSID
Wireless Mode - AP
Wireless Network Mode - Mixed
Wireless Network Name (SSID) - 2gssid
Wireless Channel - 6 (normally pick 1,6,11)
Channel Width - Wide HT40 (or 20Mhz)
Extension Channel - upper
Wireless SSID Broadcast - Enable
TurboQAM (QAM256) support - Disable
Optimize Multicast Traffic - Enable
Explicit Beamforming - Disable
Implicit Beamforming - Enable
Airtime Fairness - Disable
Network Configuration - Bridged

Virtual Interfaces wl0.1 SSID
Wireless Network Name (SSID) - 2gv1ssid
Wireless SSID Broadcast - Enable
AP Isolation - Enable
Optimize Multicast Traffic - Enable
Network Configuration - Bridged

Virtual Interfaces wl0.2 SSID
Wireless Network Name (SSID) - 2gv2ssid
Wireless SSID Broadcast - Enable
AP Isolation - Disable
Optimize Multicast Traffic - Enable
Network Configuration - Bridged

Physical Interface wl1 - SSID
Wireless Mode - AP
Wireless Network Mode - Mixed
Wireless Network Name (SSID) - 5gssid
Wireless Channel - 161
Channel Width - VHT80
Extension Channel - upper upper
Wireless SSID Broadcast - Enable
Optimize Multicast Traffic - Enable
Explicit Beamforming - Disable
Implicit Beamforming - Enable
Airtime Fairness - Disable
Network Configuration - Bridged

Virtual Interfaces wl1.1 SSID
Wireless Network Name (SSID) - 5gv1ssid
Wireless SSID Broadcast - Enable
AP Isolation - Disable
Optimize Multicast Traffic - Enable
Network Configuration - Bridged

Command to all SSIDs, I Enable Implicit Beamforming & Optimize Multicast Traffic.

Wireless Security on all SSIDs are WPA2 Personal / AES with Default 3600 Key Renewal

For Advanced Wireless Settings ALL but 2 settings are Default. For the 2.4Ghz Beacon Interval = 225 and DTIM Interval = 2. The 5Ghz I use Beacon Interval = 150 and DTIM Interval = 3. They both add upto 450ms which works for my devices and help with all the SSIDs coming off those 3 antennas.

Hi Mac913,

I tried it immediately after your post but I took some time to see whether it stayed stable. And it is! I reset my router before but the problem persist. But I guess the statement [erase nvram && reboot] did it. Now I'm able to have multiple VAPs. Thanks for the tip and also for sharing your configuration.
