RB951G-2HnD as AP with 2 VLANs

Tue Oct 07, 2014 4:41 am

We recently upgraded the network in our church with a CCR-1016-12G cloud core router and a RB951G-2HnD used as an access point. I configured 2 VLANs (SSIDs=Prayer and KBCfreewifi) in addition to the primary network (SSID = KBC). These are trunked together to the CCR. There are separate IP pools set up for the VLANs, and a hotspot splash page for the public wifi.

Everything works as intended, for a few minutes. Initially, the wireless clients get the proper IP addresses from the correct pool, and the public wifi users see the splash page before they get on the internet. After about 5 minutes, the connection stops. The clients are still connected to the AP, but there's no internet access. Nothing can be pinged, internal network or external. Walk away and come back 30 minutes later, you can connect again, but with the same behavior. I logged wireless events and you can see that the AP lowers the connection speed until it just gives up and disconnects due to 'excessive data loss'.

Any help will be much appreciated! The 951 config is listed below.
