Problems with Asus RT-AC66U B1 mesh nodes
Problems with Asus RT-AC66U B1 mesh nodes
I have two Asus RT-AC66U B1 devices linked together using Ethernet (CAT6). One serves as the main connection to our fiber modem, while the other acts as a mesh node connected via CAT6 to the main router. The PC attached to the node receives full 600Mbit speeds over the fiber, which should work well. However, phones connected to the node perform significantly slower—even when near it—compared to the main router. Most devices simply connect to the main router instead of the node, making the wireless point less useful.
Geographically, the fiber modem and main router are located at one end of the house, whereas the node sits at the other. Placing a single WiFi router in the middle isn’t practical due to distance. To ensure everything functions properly, I upgraded the setup and both devices now show they’re running the latest versions.
But upon checking the firmware details, there’s a discrepancy: the last few digits differ slightly. Is this intentional? It might be a checksum or version identifier. The connection status displays poor performance with an error suggesting it could be disabled. The device powers on and the PC connected to the node maintains a stable signal. Yet, the PC on the node still receives full 600Mbit speeds.
The Asus manual repeatedly emphasizes that both the node and main router must share the same firmware. How can I ensure the node matches the main router’s version? The node restricts direct access, requiring a reset to restore full functionality. If this is due to router limitations, upgrading to a better mesh solution might be worth considering.
If the core issue stems from poor router performance, replacing it with a solid WiFi 6 router could eliminate the need for a mesh network. However, if the problem persists, I’m open to exploring further fixes or alternatives. This situation seems unrelated to my remote work challenges, but could have arisen from flaky connectivity. Updating firmware and rebooting should help resolve any lingering issues. What steps could you try next?
Visit Asus' site for the AC66U B1 and check the firmware options. You'll find multiple versions, with the newest being 3.0.0.4.386_52048. The router running 3.0.0.4.386_51733 is outdated and may need an update if your issue relates to improvements in the newer release. Proceed carefully and consider a manual update. Before connecting as a mesh node, reset the AC66U B1 to default settings. Also, assess your wireless setup—high congestion could be causing connection problems for clients. Use a spectrum analyzer near the node to identify interference sources.
Thanks. I'm about halfway done with the Asus software. On the mesh router, resetting wasn't straightforward—the reset button didn't trigger the proper process, and even after uploading the firmware manually, logging in was slow and frustrating. The interface kept rejecting the password multiple times before waiting. I also tried using Asus Device Discovery, but it only detected one router at a time, unlike when it worked for both devices previously. My main router still functions, though I can't reach it. I'm considering switching to a new Wi-Fi 7 router to avoid these issues and the slowdowns. Right now, a solid router seems more reliable than Asus hardware. I'm curious about other brands these days—something fast and stable would be ideal. The mesh setup didn’t perform well either; maybe a traditional router would suffice for coverage. What should I look for? A model that avoids the bugs and slowness I've experienced with Asus? I’m also thinking about resetting the firmware automatically, just in case it introduces risks, or maybe skipping the mesh altogether and using a separate router with a central hub. Plus, I wonder if updating to automatic updates could help prevent malware from Asus servers. And honestly, given how outdated these devices are, they might not get much support anymore.
