UPDATED: I have still not been able to resolve this (even after buying an 802.11at PoE supply. It's driving me nuts... If anyone can give me a nudge in the right direction it would be very much appreciated.
I have a WAP571, a HP 2350-24G-PoEP and two laptops set up in a very simple VLAN/WIFI experiment.
Two laptops both connected to the AP on GUEST-5G can ping each other.
BUT, they can't ping the default gateway (192.168.60.1) or other wired devices on the 192.168.60.0 subnet.
Any device connected to the AP on GUEST-2G can ping the default gateway just fine.
I am at a total loss here.
When Test Laptop 1 is connected to GUEST-5G, the MAC addresses are correctly mapped to the right ports and VLANs on the switch. Test Laptop 2 has Test Laptop 1 in its ARP table. But, Test Laptop 1 has nothing for Test Laptop 2.
Below are screen shots of the AP configuration.
I can't see any difference between GUEST-5G and GUEST-2G apart from the fact that they are 2G and 5G.
I was getting a warning about 5G not being supported by the PoE:
BUT, we bought a better PoE supply and I can see in the web management that the AP is using 802.11at.
I cannot for the life of me work out why this is happening or even what other tests to do....?
