TP-Link TL-MR3420 – 300Mbps 3G/4G Wireless N Router
The TP-Link TL-MR3420 is a 300Mbps Wireless N router designed to share internet from a 3G/4G USB modem (dongle) or from a standard wired broadband connection. It is commonly used in areas where fixed fiber or DSL internet is limited, allowing users to create a WiFi hotspot using mobile data.
Key Features
- Up to 300Mbps wireless speed (2.4GHz WiFi)
- Supports 3G/4G USB modem (dongle) sharing
- Can also work with Ethernet WAN (wired internet)
- Up to 32 devices connected simultaneously (typical usage)
- Failover support (switches between mobile and wired internet depending on availability)
- Simple web-based setup interface
- WPS button for quick WiFi connection
How it works
The router does not contain a SIM card slot itself. Instead, it uses a USB modem (dongle) that connects to the router. The router then converts that mobile internet signal into WiFi for phones, laptops, and desktops.
Ideal Use Cases
- Homes without fiber or fixed internet
- Rural or remote areas
- Backup internet connection for offices
- Small shops and cyber cafés
- Temporary internet setups (events, field work, etc.)
Performance Note
- This is a 2.4GHz Wireless N router, so speeds are suitable for:
- Browsing
- YouTube streaming (HD depending on network)
- Online classes and meetings
- It is not a high-speed gaming/router for modern fiber networks, but it is stable for basic and mobile internet sharing.
