Before you begin

Confirm the service and gateway model. A missing control is not evidence that a hidden administrator page will unlock it.

Procedure

1. Read the official restrictions: the documented gateway does not offer bridge mode, NAT-type changes or port forwarding.
2. For added Wi-Fi coverage, check whether your own equipment officially supports AP/bridge operation behind an existing router.
3. Apply that device’s AP-mode instructions; do not invent a T-Mobile bridge toggle.
4. Retest household devices and any guest-network behavior.
5. For remote access, ask about supported reachability rather than promising inbound VPN-server access.

Verify the result

Clients have usable internet and the new device is operating in the mode you intended. Test latency and roaming separately.

Undo or recover

Disconnect the added device and return clients to the original gateway network.

Stop and escalate

Corporate VPN issues should go to the employer’s IT team and ISP. Client VPN compatibility does not prove server reachability.

Evidence and interpretation limits

The official page also limits gateway DNS editing; device-side DNS controls are a separate matter.

The steps above combine paraphrased official instructions with an original safety and test workflow. They are not a verbatim manual, a guaranteed fix, or evidence of a common hardware defect.
