Hi baloba2, 

Sorry for not getting back to soon, I suggest contacting Support for this issue to be looked at. It's possible that it needs to be escalated to engineering. 

Thanks, 

I just upgraded to the 4-1 firmware and I am experiencing the same thing only the list is completely blank. No clients whether they are hard wired or wifi are showing up. I did a factory reset after each load of the new firmware (twice,1 for primary and 1 for secondary)

Hey I ended up calling into support and they told me you must select refresh after selecting the LAN Groups screen. Not thrilled with their response but it did work for me.

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.

Hi, I am having the same issue right after I have upgraded my SRX5308 to the latest firmware version 4.3.4-1. The LAN Groups (Network Configuration > LAN Settings > LAN Groups) page is empty. I used to be able to see all the network devices with the previous version 4.3.3-8. I have tried 3 different browsers (Chrome, Firefox and IE11) with cache and cookies cleared, inprivate mode, etc, nothing works. It's definitely an issue with the latest firmwire version 4.3.4-1 because if I roll back to the previous version 4.3.3-8 then it works fine. Can someone please help me? I need to be on the latest version because it has a fix which allows an IP address to be in multiple IP Groups (Security > Services > IP Groups).

For me Firefox gave the 5308 (434-1) a kick so it started to present the listing in the Lan Group and after that it also worked for IE and Chrome.

The listing seems to me to be random. Is is possible to have it sorted by IP number? That would be so much easier to work with.

Thanks,

Henrik
