TP-Link TL-MR100 is a 300Mbps Wireless N 4G LTE Router designed to provide internet connectivity using a compatible Nano SIM card. It combines a 4G LTE modem, 2.4GHz Wi-Fi router and Ethernet connectivity in a compact desktop form factor, making it suitable for homes, small offices, shops, temporary sites, branch locations and areas where wired broadband is unavailable.
The router supports theoretical 4G LTE download speeds of up to 150Mbps and upload speeds of up to 50Mbps, while its 2.4GHz 802.11b/g/n wireless network provides a theoretical wireless rate of up to 300Mbps. Actual internet and Wi-Fi speeds depend on the mobile network, signal strength, carrier conditions, connected devices and other environmental factors.

4G LTE Internet with Nano SIM
The main purpose of the TP-Link TL-MR100 is to provide internet access through a mobile 4G LTE network. Instead of connecting the router to a fixed broadband modem, users can insert a compatible Nano SIM card and use the mobile network as the WAN connection.
This makes the TL-MR100 useful for locations where fiber or DSL broadband is unavailable, as well as temporary offices, retail counters, remote work locations, backup internet connections and other deployments requiring a cellular WAN.
TP-Link specifies LTE theoretical download speeds of up to 150Mbps and upload speeds of up to 50Mbps. These are cellular modem specifications rather than guaranteed internet speeds. Actual performance depends heavily on the mobile operator, supported bands, signal strength, network congestion and location.
Supported 4G LTE Bands
According to TP-Link’s India product specification, TL-MR100 supports the following LTE bands:
| Network |
Supported Bands |
| 4G FDD-LTE |
B1 / B3 / B5 / B7 / B8 / B20 / B28 |
| 4G TDD-LTE |
B38 / B40 / B41 |
| 3G HSPA/UMTS |
B1 / B5 / B8 |
Supported frequency bands are important when selecting a cellular router because mobile operators use different bands in different locations. Always check current carrier compatibility and the exact hardware version available in India before deployment.
300Mbps 2.4GHz Wireless N Wi-Fi
TL-MR100 provides a 2.4GHz IEEE 802.11b/g/n wireless network with a theoretical maximum wireless rate of 300Mbps.
The 300Mbps figure is the wireless PHY/signal rate, not the expected internet download speed. The actual throughput available to connected devices will normally be lower and depends on wireless conditions, channel utilization, device capabilities and the available 4G internet connection.
The 2.4GHz band is widely supported by laptops, smartphones, smart TVs, IoT devices and other Wi-Fi clients, making the TL-MR100 suitable for basic wireless internet sharing.
Two Detachable 4G LTE Antennas
The router includes two detachable external 4G LTE antennas connected through external SMA-F antenna interfaces. The external antenna design can be useful for positioning the LTE antennas to achieve a suitable cellular signal at the installation location.
Cellular performance should be evaluated based on actual signal conditions at the deployment site. External antennas do not guarantee a particular LTE speed because mobile network performance also depends on tower coverage, carrier configuration and network congestion.
10/100 Ethernet Connectivity
TL-MR100 provides two Ethernet interfaces:
- 1× 10/100Mbps LAN port
- 1× 10/100Mbps LAN/WAN port
The LAN/WAN port provides flexibility because it can be used as an Ethernet WAN connection when the router operates in Wireless Router mode.
Important: the Ethernet interfaces are Fast Ethernet 10/100Mbps, not Gigabit Ethernet. Therefore, wired devices connected directly to the router are limited by the 100Mbps Ethernet interface.
Wireless Router Mode
TL-MR100 can also work as a conventional wireless router when an Ethernet internet connection is available. TP-Link lists 3G/4G Router and Wireless Router as supported operating modes.
Supported WAN connection types include:
- Dynamic IP
- Static IP
- PPPoE
- PPTP
- L2TP
This allows the TL-MR100 to be used with either a compatible cellular connection or a wired Ethernet WAN connection.
WAN Failover
TL-MR100 supports WAN failover, allowing the router to use an alternative WAN connection when supported conditions require switching between available internet sources. This can be useful in installations where maintaining internet availability is important.
Guest Wi-Fi Network
The router supports a separate 2.4GHz Guest Network. A guest network can be used to provide internet access to visitors while keeping guest devices logically separate from the primary network according to the router’s supported configuration.
Network Security
TP-Link provides several basic network-security features on the TL-MR100, including an IPv4 SPI Firewall and IP/MAC address binding.
Wireless security includes support for WEP, WPA and WPA2-based encryption modes listed in the product specifications.
Port Forwarding and Network Services
TL-MR100 includes common router functions for managing inbound and outbound network traffic. Supported features include:
- Virtual Server
- Port Triggering
- UPnP
- DMZ
- ALG
- Dynamic DNS
- DHCP Server
- Address Reservation
These features can be useful for applications requiring specific network-access or port-management configurations. Actual inbound access over a 4G cellular connection can also depend on the mobile operator’s NAT and addressing policies.
Dynamic DNS
TL-MR100 supports Dynamic DNS services including DynDNS and NO-IP. Dynamic DNS can provide a consistent hostname for supported remote-access applications when the WAN environment permits incoming connectivity.
