New here, but I'm testing these BE30000 units, and had just a total $hitshow on my first night, Friday, and then all day Saturday. I finally got a reply from support for my issues Tuesday and now half of my issues are at least resolved.
About 3 weeks ago I replaced a Wifi6 Asus gaming firewall with an Eero Max 7 that I absolutely LOVED. Single SSID and every one of my 140 or so smart home devices connected just fine, and my higher speed devices like my Surface Pro 11 with Wifi 7 was able to copy files to my Synology or my media center PC (both on 10GB network cards since my wired network is 10GB) at about 250MB/s.
Got this Asus system, and it forced the IOT network out of the gate, so I figured I would go with it. All my devices would show as devices in the web GUI or the app, even get IP's, but everything showed offline in every smart app I use. Spent 12 or 14 hours nuking everything, rebuilding, trying different ways, different settings, and only once did my devices finally actually connect to the internet and show online - and of course I wanted to reboot to see if this miracle working would survive the reboot, and it did not.
But my other devices like my iPad, iPhone, Surface Pro 4, Surface Pro 9, Surface Pro 11, media center PC, all these things worked fine to get to the network. The wireless ones I could use on either my main Wifi7 wireless network or on the IOT secondary wireless network, and get to the internet just fine, but the smart devices just would not. And whereas my Eero lets my Surface copy files to my Synology or Media center PC at 2.5 MB/s, the Asus here has me stuck at Wifi 6 speeds and maybe 110 to 120MB/s, just like the old Wifi 6 network did, despite my Surface showing a 6GHz connection and a link speed of 5764 Mbps.
What Asus had me do for MY situation was simple and worked immediately for all of my smart home devices.
First, in the web GUI I had to go to Wireless > MLO and turn off the MLO feature.
Then under Network, on the main network, they had me disable the 2.4GHz band.
Once I did that, every single one of my smart devices came online just fine. I've swapped back and forth between the Eero Max 7 and this Asus unit multiple times as I tested things and every time, when I shut down the Eero devices and power on the Asus, things work and all my devices are back online.
So if someone is having issue with their smart devices, this may be worth seeing if it helps in YOUR setup.
Now I'm just waiting on them to give me options for how to increase my file copy speed from my Surface Pro to the faster hardwired network objects. There is no way I'll hold onto this Asus setup as long as I can only copy file-s at 40% of the speed of the Eero unit...
So if anyone has any settings to help increase the file copy speeds on the Wifi 7 main network I'd love to hear them. That is now my only issue.
When I swap the Asus and Eero units, the main Asus and Eero units are both put in the exact same spot, and using the same cable then to uplink to my 10GB switch downstairs. So my Surface is the same distance from each, physically they're in the same spot, and they're using the same Cat-6 cable. And it's consistent over the last week now, every single time, so it's not just some random thing that is just making the Asus slower only when I'm testing. This is too repeatable and consistent every single time.
Oh, forgot to mention I'm not using wireless backhaul, both my satellites are hardwired.
Anyway, hope those suggestions may help someone else with the devices side of things.
