[Solved] TP-Link MR6400 Router with LTE Modem: Internet Connectivity Drops After Certain Duration

Hello,

I have a TP-link mr6400 router with LTE modem, after firing I installed an ORANGE sim card with the Internet and everything started working
After running the Speed test download at 25 Mbit (test from the phone about 4, so the router has strengthened the range)

The problem appeared because after a few hours suddenly information that the internet was unavailable (connected to the router but on the phone and computer exclamation mark), on the TV there was also no Internet, rest the device works and then again the same and sometimes it is like that the Internet crashes after 5 minutes and sometimes half a day comes and it's ok

I will add that I installed the same card in my phone, I made a hotspot and the Internet went all day and nothing, I transferred it to the router and then the same

And what was the point of buying the MR6400? Weak, expensive LTE 4 category router. Without basic signal diagnostics, without the possibility of forcing specific LTE / 3G bands, not to mention aggregation of LTE bands. Worth PLN 200 Purchase of equipment instead of showing screenshots of Network Cell Info from the phone was a weak idea. The router does not strengthen anything because it still stands at home. It is not known which BTS, what technology and bandwidth the MR6400 uses, what are the signal parameters. The same goes for the phone. BTS NetWorks Rzyki os. Are you happy already? https://www.telix.pl/operatorzy/orange/2018/01/mieszkancom-rzyk-orange-buduje-bts/

With all due respect but you probably talk about a different router because the one I have This shows some connection technology uses, shows the frequency and signal strength and you can change and set 4G or 3G as much as possible and only through the Internet router it comes with 4x faster speed than in phone which means that it strengthens the signal.

The new transmitter works (information from the operator) but I just called and it turned out that something is interfering with the transmitter, probably a lot of people use range amplifiers and they interfere with the transmitter

Questions can this be the reason for my problem?

Interestingly, the phone shows Full coverage everywhere but when it comes where to call it terribly interrupts

You know everything the best, why do you ask? The router strengthens the signal, everything is good to use, tell the operator which neighbor is using the amplifier and after trouble. And MR6400 I know very well and what I wrote is true. The basis of LTE routers is the ability to choose a specific LTE or 3G band using WebUI or an external application. MR6400 does not have this function. In Poland, operators use FDD: LTE2600, LTE1800, LTE800 as well as LTE2100 and LTE900 and TDD2600 (Plus), on the TP-link you will not choose a specific band. Choosing 3G or 4G is not a choice. The router does not have any advanced LTE signal diagnostics because showing the signal strength in% is laughter in the room. LTE has its parameters, I suggest you read them http://jackiewiczowie.blogspot.com/2014/10/parametry-sygnau-lte.html Router for PLN 400 with WiFi on 2.4GHz, LAN100Mb / s, without a USB port or RJ11 is a failure. Represents the B593s-12 level from 5 years ago. Today, 6 category LTE-A routers are bought for its price with aggregation of two LTE bands, Gigabit LAN / WAN ports and WiFi in AC, USB port for mass storage / printers and RJ11 port for GSM / VoIP gateway. The router does not strengthen anything, no comparison of the signal parameters on the phone and MR6400. It is not known which LTE or 3G band the phone uses and which router so the speed comparison is unreliable. At BTS Rzyki Orange has licenses for LTE1800, LTE2600 and LTE800, it is not known which work, it is possible with all and aggregation of these LTE bands. Plus UMTS2100HSPA + DC and UMTS900 on 3G. Having a router with LTE-A and the ability to select LTE bands and aggregation, you can choose the optimal band or aggregation of LTE bands and check the BTS signal and CID parameters. But for this you need to at least show screenshots from the LTE phone with the Network Cell Info application. You can choose your way and the advice of Orange consultants and buy a router that does not meet the requirements of the LTE Orange network, which on the new BTS runs several LTE bands and their aggregation.

I know that you have a lot of knowledge on this subject, and you know it better, in addition, you devote your time to help and I respect it very much! I am sorry that maybe I wrote so, it just irritates me all this. I need a router only for everyday use (and unfortunately for work) browsing, connection to the TV and this router what I have it meets my expectations just simply "loses" the Internet.

I will do a call info test in the afternoon and send it as it went.

Call info details



but if someone uses these signal amplifiers then I understand that unless someone turns it off the transmitter will not work ?? Even despite the fact that there is something working with the transmitters all the time, I can even see that when it is dark, with the headlamps it is on the air and doing something there

The router worked in a car I changed to 3G work and now it works fine. greetings
