Can I get an Internet connection even if I can’t get broadband?
This TL-MR3420 TP-Link router is perfect if you have a bad or non-existent cable/ADSL internet connection, as this router can share a 3G/4G internet connection too. It has been tested and works with a range of LTE/HSUPA/HSDPA/UMTS/EVDO USB modems. All you need to do is connect the modem to the router and you’ll be providing access to the internet in no time. Locally sharing a HD video takes only a few minutes, with transfer speeds of up to 300Mbps. And with a range that is better than the legacy 802.11g products, you can do it at a good distance as well.

Bandwidth is limited on 3G/4G connection and in order to ensure your high priority devices/applications take priority you can control the bandwidth each device is allocated. This allows you to prioritise activities such as gaming, ensuring you get as little lag as possible. Your connection can be shared with family or friends via a wireless or wired connection, where a wired connection will provide you with a more reliable connection.

Can I connect wired devices?
Four 10/100 Ethernet ports can be used to connect any wired devices to your network. A WAN Ethernet port is also located on the router, so you can connect it to an ISP’s modem and use it as a router for your cable/ADSL internet. The possibility of combining a 3G/4G and WAN connection means you can set up a connection backup. You can define whether the 3G/4G or WAN is preferred and when your preferred connection fails it will keep you online by switching to the other. This gives you a lot of flexibility and guarantees you with an ‘always online’ internet connection.

Is the setup for this router straightforward?
Simply connect a 3G/4G modem to the router and a Wi-Fi hotspot is instantly set up for you. You can then connect multiple devices to it to gain access to the internet and share data and applications wirelessly. Alternatively, you can connect the router to a more traditional modem via an Ethernet cable. Adding devices to your network is easy too, with a WPS button on the router, which sets up a secure connection without you needing to enter in the password.

If i were to use a 3g SIM modem with this router and sent the internet connection via ethernet to my laptop, would the internet being used count as Hotspot data allowance or regular on my SIM contract?

Asked by: patrick
As the 3G modem would be connecting to the available 3G services in the area, this would count as data used on the 3G SIM as this is the connection point.

Does this have an Ethernet connection that I can plug in to Hive Hub and hence access Hive via 3G or 4G connection? I do not have a broadband internet wired connection.

Asked by: Alan at DhH
Unfortunately we are unable to guarantee full compatibility for this item in your intended application, as this is not the manner in which it was designed to be used.

If I put a SIM card in which is 3 or 4 g enable, can I connect it to my office network via the patch and it will provide data to my existing network? Just as the normal broadband hub does? In addition will it provide wireless data too? Thank you

Asked by: Frankie
This does not take a Sim & would require connecting to a 3G/4G USB modem. It can be connected via patch to your existing network to provide WiFi.
