SRX5308 - DHCP client list not working after upgrade to 4.3.4-1

Hi bhoth,

I appreciate your update.  I'm glad that NETGEAR Support has helped you with your concern.

Well, in the past whenever you went in to the LAN groups page it would do an ARP request for every valid host address in the subnets configured for your LAN, this resulted in a long delay before the page would load. Some people complained about this since it slowed down things such creating / editing LAN groups or making DHCP reservations. There was a feature request to make the client scan only run when requested and it seems as if that is what was implemented in the latest firmware. 

I would say that the placement of the refresh button is not very intuitive though.. Very easy to miss, and it's not really explained in the release notes either so I can definitely see this causing confusion.

Worth noting is that it's not really a DHCP client list but rather a 'all devices on the network'-list, in the sense that it will list any device connected regardless if it received IP through the SRX's DHCP server or not.

Regarding devices showing up as "unknown", I'm not sure really.. I would assume that it uses netbios to figure it out, but I'm not sure why it would sometimes fail. A packet capture on the LAN side of the SRX while doing a "refresh" might tell why some devices shows up with a hostname while others don't.
