    Don't ignore because of low reviews, especially from people who don't know

    Setup may require some patience, research, or knowing what you’re doing. For example, you might need to configure a separate IoT network for older devices or cameras that won’t work well on a Wi-Fi 7 network. I had one unit stop working, and I struggled to reset it. I ended up spending an hour troubleshooting before it worked again. However, no other device in this price range could check all of my boxes. Once I figured everything out, I’m extremely happy with it.

    A few issues but got it going.

    Had issues with the app setup so had to do a manual install. Took a while for it to connect all 3 but got it working. Sometimes there seems to be a lag in the signal and get spinning circle when trying to stream video on tv. Otherwise seems good with my new ISP.

    Awesome with no subscriptions and a three year warranty and WIFI7 ready!

    I was looking for a good router with satellites ever since my Netgear Orbi RBK50 bricked itself during an update. Great job, Netgear... NOT! And being out of warranty, they delicately showed me the finger. Well, I decided to return the favor.I digress, but I had bought that Netgear with 2 satellites because it had a dedicated backhaul, 2.4 and 5GHz bands and that it is a reputable brand. What I didn't realize is that they nickel and dimed me for full 3+ years for their Netdefender subscription of almost $100 annually! So on top of paying top dollar ($450+ to be exact), I was paying $100 after

    A lot of wasted time

    Not the greatest product from Asus. Connections drop often, AI Mesh is not very reliable. The worst part is that after the latest firmware upgrade as of 08.2026, the client nodes are not visible from the main unit. To fix the connections among 3 nodes, I had to reset them manually, upload a new fw to each one, and create a mesh network a new. All of that but several times since the attempts were not successful on the first try. It all worked at the end, just took me one full day to make it work.

    Connection issues.

    Very poor product. They are setup as nodes to xt9. Had one started to allow devices to connect but then device go offline. Showing device on connected to a bd4. Sent first unit back awaiting its replacement. Now a second one has started the same issue. Hoping the third died not experience this too. Pain in the rear.

    Not as good as promised

    Really not a great experience. Backhaul wasn’t working automatically / with “Ai mesh optimization”. I got 500Mb between 2 units about 5M apart.Going to try the Orbi 770 instead

    ASUS ZEN WiFi BD4 meets expectations

    There is a learning curve involved in setting up the BD4 Mesh unit. This can be solved by going back to the beginning and be sure you follow instructions implicitly. Be sure you review and take the time to understand them. 5 days after I started using the system I woke up to an internet failure, and for some reason the main unit had stopped communicating with the Internet provided router. This was easy to identify and rectify. My speed tests are approximately 10% higher than my previous mesh unit and connectivity is quick and seamless now. Very Satisfied.

    Cheat upgrade for your home network

    If you want to upgrade your home WiFi to a mesh system and increase you signal strength without changing cable providers this is your cheat code. The best part you can’t have multiple WiFi networks for different folks in your house. For the price this is common sense decision.
