Identify the exact hardware
The B535 is a 4G LTE CPE router. Check the label and any hardware or regional identifier before using firmware, recovery instructions or screenshots intended for another product.
How this product is managed
The B535 combines local router management with mobile-broadband controls. Depending on firmware and region, management may be available through a local interface or Huawei app.
Why the B535 needs its own guide
Unlike a fibre or cable router, the B535's upstream Internet connection is the LTE radio. SIM status, APN, network registration and placement are therefore more important than ordinary WAN-port troubleshooting.
Setup sequence
- Insert and activate the correct SIM.
- Confirm the gateway registers on the mobile network.
- Check the APN only when the provider requires a custom value.
- Position the unit for signal quality, then configure local Wi‑Fi.
Start diagnosis here
A client can have excellent Wi‑Fi to the B535 while the mobile connection is weak or offline. Compare placement, signal indicators and mobile-network status before changing wireless channels.
A mistake to avoid
Do not expect a factory reset to improve 4G coverage. Signal, carrier load, supported bands and the physical location of the gateway are usually the limiting factors.
Verify the result
After any change, repeat the original test instead of relying only on a successful save message. Check the upstream connection, one wired client where applicable, and the affected wireless or managed device separately. Record the setting that changed so it can be restored if the result is worse.
