I don't know if this is a bug or compatibility issue, but when I use Chrome, the WebGUI hardly works. It takes 1-2mins for the login screen to come on. And if I do get to login almost 75% of the time...

+1 for the ER8411

In order to have LAG/LACP you must have STP the very least. or else the switch will just loop. They don't even have STP in the ER8411. Kinda sad.

Give us a IGMP querier option so the ER8411 don't try to be the host when there is a IGMP host established within the network.

yes but there isn't an equivalent in the webgui, at least not I found where I can see all the ip and mac and their vlan

The "next" model that going to replace the 8411 should have at least 2x 10Gb ports for LAN... one being at least a 10GBase-T port. Just look at your competitors they got 2x 25Gb ports
