Questions about TP-Link Tl-Mr6400

There is no GSM antenna port.

I can now answer the question myself: With Swisscom, I use LTE band 3 (1600MHz). Sunrise/yallo uses LTE band 20 (800MHz). The latter allows coverage of a larger area (e.g. in the countryside), but usually at lower speeds. In my case, the Sunrise band 20 is significantly stronger than the Sunrise band 3, which is why the router selects the slower band 20. The official firmware does not allow manual selection. However, there is a beta firmware in which you can select the band (Google search helps). Installed and selected band 3 manually. And look: at least 9Mbit/s up and down. I can live with that as a backup internet connection.

Unfortunately, as far as I know, this is not possible with this model (TL-MR6400). However, the following device supports this: Tp-Link Archer MR600 (~CHF 130). However, you have to log in to the router with a web browser and go through several submenus until you get to the traffic monitor. The mobile app from TP-Link ("Tether") does not yet support this. (I have tested the iOS version). I myself use both TL-MR6400 models and the TL-MR600. The web interface looks exactly the same, with the TL-MR6400 some things have simply been removed, such as the traffic monitor and internet speed test.

Yes, data roaming can be activated or deactivated. Caution: Often it is then necessary to enter the APN parameters manually. Relying on automatic detection does not always work with "exotic" combinations, see also https://www.digitec.ch/de/s1/ProductRating/funktioniert-gut-roaming-nur-mit-kunstgriff-182097.

no idea . already disposed of it.

The router has a firewall that monitors and protects network traffic, but it does not offer any specific content filtering functions for children. However, there is a function called "Parental Controls" that allows you to restrict access to certain content by restricting certain devices or users. However, this function is not specifically aimed at content filtering, but rather at controlling access at certain times or for certain devices. Comprehensive content filtering may require additional software or services.

I plugged in the sim from Digital Republik and entered the PIN specified on the device. Since then the device has been working perfectly. I don't remember making any further entries.

If the person who sporadically watches TV on the iPad already has a smartphone, then a router that needs its own SIM card doesn't make much sense. 4G with good reception is enough for TV.

My SIM is from Swisscom; I am happy with the performance of the device and also watch TV on it.

I use it in my motorhome - I have a range of around 5 metres - the illumination covers the motorhome and vehicle sufficiently.

The first question is much more about what you want to achieve. Failover to LTE when DSL is not available, load balancing etc.. However, if you have a "Profinet" - Fortinet, you should also have the appropriate certifications to set this up easily. Because without certifications you can't just buy them - not end customer devices, but for professionals...

Depends on your SIM card, the device gives a maximum of 300Mbps. DIGITEC offers a pure data plan with 300 MBPS for CHF 330/year. Exactly suitable for this device. I also bought a SIM from Digitec. Works perfectly with the TL MR 6400

No need for an extra antenna!

Hello, I can't say that with 100% certainty. However, I very much assume so. Any physical card with a data tariff should work. I have the one from Aldi and it works perfectly. Hope I could help a little

Yes

Ciao Marvin22 I also use this thing abroad. With me it was that I reached the "free" volume of the provider. Then I had a speed of under 1Mbit/s. Check it in your Cockpit: https://cockpit.wingo.ch/

If you cannot find the original, you can buy a universal. They are usually sold with different adapters and adjustable voltages. However, check that you have the same type of plug and that it has the correct electrical characteristics (Voltage and Amperage).

Sorry, but I never had such a device, or can't remember

Yes, you can, because the two connections are not for the WLAN, they are for the LTE reception. However, I wouldn't recommend this router because its LTE 4G module can only do a maximum of 150 Mbps. That's very poor. And the LAN ports are only old 100 Mbps ports, with a maximum of 32 devices, which doesn't match. This model Archer MR600 is much better, it can do up to 300 Mbps LTE 4G+, up to 64 devices and also has four Gbit Ethernet ports. TP-Link Archer MR600

Yes that goes without a problem
