Do You Need a Router with AT&T?
Yes, if your AT&T WiFi is slow, unstable, or weak in parts of your apartment. The AT&T gateway handles the internet connection, but its built-in WiFi is not always the best option for apartment layouts.
A better router helps with:
- Weak signal in bedrooms
- Dropped video calls
- Buffering on smart TVs
- Slow WiFi during busy evening hours
- Neighbor WiFi interference
- Too many devices connected at once
For AT&T Fiber, keep the AT&T gateway connected and use your own router behind it. For most users, the Archer AX55 is the simplest upgrade.
