Good Morning All, 

 

A bit of a strange issue I'm hoping to get some assistance with. 

 

I have an ER7212PC with 3 access Points, EAP650, EAP650-OUTDOOR, EAP615-WALL. 

 

Internet is Dynamic IP and at that level I have 1.1.1.1 and 8.8.8.8 set as the DNS Servers. 

 

I have two networks (interfaces) configured

LAN is the default, Vlan ID 1. 192.168.0.x

IoT is the second, Vlan ID 9. 192.168.1.x

Both use a self hosted DNS server at 192.168.x.254.

Dhcp enabled on both. 

Ipv6 disabled on both. 

 

Ports to the APs are configured to carry both VLANs

 

I have two WLANs, "Home" and "IoT". 

Home has no VLAN configured.

IoT is configured to Vlan 9.

 

 

There is one ACL in place, blocking traffic from Vlan 9 to Vlan 1.

 

For the most part, everything is working as intended. Both networks have internet access. Both distribute ips, my self hosted dns is working. Devices on Vlan 9 cannot see anything on Vlan 1.

 

 

Now the issues:

 

Some devices, wireless or wired (via the 615-wall) will take ~2 minutes to establish an internet connection on the LAN/Home network/Wireless. 

During this time, I can ping the gateway (192.168.0.1), but pinging 1.1.1.1 will fail. The device gets a valid ip via dhcp and correct gateway/dns information. 

Eventually 1.1.1.1 will start responding. 

Ive only tested this part with wifi as I don't have many IoT ports available, but if I  disconnect a wireless device from Home while it is in this weird state, and connect to IoT, it gets internet connectivity immediately. 

Swapping back to home, same issue. 

 

 

Another, less pressing issue, is that 802.11r was causing a Samsung device to have a ~5s delay in loading webpages. Disabling 802.11r has resolved that, but I would like to keep it enabled. 

 

Final, also minor issue, devices (I.e. my phone), seem to be getting ipv6 addresses even though it is disabled at the interface (ipv6 interface = none). 

 

 

Anyway, for the more pressing issue. Things i have tried:

Setting the Vlan ID of "Home" wifi to 1. This caused internet to drop out. 

Setting dns to 1.1.1.1 and 8.8.8.8 at all locations. No change. 

Disabling acls. No change. 

 

Things that may be relevant:

The IoT vlan/wifi was only added recently. Prior to this, both the 802.11r issue and the delay connecting to internet issue were not seen. 

The issues have only started since adding the IoT vlan/wifi. 

 

I'm hesitant to reconfigure my whole network. I have a feeling though that if I created a new network interface i.e. "Home" on a new vlan, and put the Home wifi onto that new vlan, I'd be ok. 

 

 

I'm holding off on that until I get some feedback here though. 99% sure I've just made a mistake in the config and someone here can help me fix it. 

 

Thanks in advance.
