My new Asus BD5 router was driving me nuts. Devices would randomly get blocked from connecting for no clear reason. Some, which worked fine for weeks, would suddenly disconnect and refuse to reconnect. Others had internet access but couldn’t browse the web. It was like the router was haunted!
After some trial and error, I found a fix that worked like a charm: I manually set the router’s IP address in the Default Gateway field under DHCP settings. In theory, leaving this blank should make the router automatically assign itself as the gateway for DHCP clients. But for some reason, explicitly setting it resolved all my issues. Every device now connects reliably, and my network is running smoothly. My family’s sanity is restored, and I’m thrilled to have cracked this one.
How to Fix It:
- Open your web browser and log into the router’s admin portal (you can’t do this in the mobile app).
- On the left sidebar, go to Advanced Settings and select LAN.
- Click the DHCP Server tab at the top.
- Find the Default Gateway field and change it from blank to your router’s IP address (e.g., 192.168.1.1).
- Click Apply at the bottom to save changes.
