## Before you buy

- The listing states Cat 6 4G+ downloads up to 300 Mbps and a maximum upstream rate of 300 Megabits Per Second, but does not clarify how the upstream figure relates to the mobile-network claim. It also lists one port while describing a LAN/WAN port and Gigabit Ethernet. Verify port roles and data-rate details for the exact listing before purchase. The stated 4G performance depends on available mobile coverage and service, and customer feedback reports mixed speed and connection stability.

- Power adapter (Included)

- Quick Installation Guide (Included)

## A good fit for

- Households or small offices seeking a SIM-based 4G internet connection with dual-band Wi-Fi.

- Users looking for app management and the option to join a compatible EasyMesh setup.

## Less suited to

- Buyers who need 5G mobile connectivity or Wi-Fi newer than Wi-Fi 5.
- Anyone relying on guaranteed mobile speeds or consistently stable reception regardless of local coverage.

## Customer feedback

Customer feedback highlights easy setup, out-of-box operation, perceived build quality and signal strength, including reports that placement around the home helped find reception. Speed and connection quality are mixed: some customers describe performance faster than broadband, while others report 6Mbps to 12Mbps or unreliable connections. These experiences matter for a 4G router because actual results depend on local mobile reception, so its listed maximum rates should not be treated as assured speeds.
- Positive themes: Customers report straightforward setup and that the router works out of the box.
- Positive themes: Some customers appreciate its portability and signal strength.
- Negative themes: Some customers report unreliable connections and low speeds.
- Mixed feedback: Customer reports of speed and signal quality vary, from faster-than-broadband performance to 6Mbps to 12Mbps.

## Frequently asked questions

### Does the MB235-4G use a SIM card for internet?
Yes. The listing describes a SIM-slot router using 4G+ Cat 6 mobile broadband. Mobile service and coverage are needed for that connection.
### What Wi-Fi speeds are listed?
The listing states up to 300 Mbps on 2.4 GHz and 867 Mbps on 5 GHz. These are stated wireless rates, not a guarantee of internet speed.
### Can it connect through Ethernet instead of 4G?
The listing describes a LAN/WAN port for Ethernet router mode when a 4G connection is unavailable. Check the port layout and role before buying, as the details also state a single port.
### Does it support mesh networking?
