[Solved] ODU-IDU 300 Error: No Internet on ASUS PR-N12 Repeater - Troubleshooting Tips Needed

Hello. Unfortunately, I have internet from polsat and the infamous ODU_IDU 300. I can terminate the contract only next year. The problem is that in the place where I have a stationary computer (an old man without a wifi card and connected to the router with a cable) the internet works. The TV hanging on it has wifi and, for example, NEFTLIX works and movies can be watched. I thought it was a problem with the signal strength, although I have 500 m in a straight line to BTS. I bought and installed an additional Dual LTE-A / 4G 17dBi MIMO 1800-2600MHz antenna, but I do not see the signal strength increasing. An apartment of about 100 m in a three-family building, old construction, so the walls are thick. From the router to the amplifier about 8 m, two walls. For two years it worked fine, but often lost range. The amplifier is an ASSUS PR-N12 repeater. Recently connected to the router, but no internet. I've tried different settings and changing the location, but to no avail. So I bought a FRITZ1200 amplifier. I can't do anything about it. Neither log into settings nor connect via WPS. LED keeps flashing as not connected. Maybe someone can advise what I should do to make this amplifier work, or what to do to make the wifi signal, and thus the internet, roam in every room - greetings Wiesław

You just tested it yourself and beautifully described why buying reporters is throwing money down the drain. You rolled it twice, so I guess you're well-learned already.
If you want a WiFi network coverage behind the wall, run a cable from the LTE router behind the wall and install ASUSA at the end of this cable in the mode of working as an access point (not a repeater!).
Return the friztbox quickly, maybe you will get your money back.
An external antenna is probably unnecessary, at such a distance to the BTS it may be worse with an antenna than without, because the signal is distorted (the signal strength does not increase anymore, but its shape changes and deteriorates the quality, and it is the quality that is mainly responsible for the transmission parameters).

Okay, I will send the FRITZBox back, PLN 250 to be recovered. It's brand new so no problem. Worse with the antenna, because two weeks have already passed. It's hard for me to swallow. I have one more idea, namely moving the ODU to the central point of the apartment. Only then the distance from the IDU that hangs outside to the router will increase and it will be 20 m in total. Won't the cable be too long?? Remove the antenna or leave it? - best regards

Do you need an antenna, then you need to perform tests. The easiest and fastest way, although not entirely reliable, is to perform a speed test on a computer connected to the router by WIRE.
A network cable is run between the ODU and the IDU. If it is a good quality cable with a certificate, according to the standard, the length can be up to 100 m without any impact on the quality of transmission. If it's some crap from a DIY store, it can be different (then it's best to replace it).
Personally, I think that two access points connected by a wire will work better than one in the middle of the house.

At first, you force the LTE2600 IDU in the management panel and show the signal parameters from the ODU without the antenna, plus speedtest, then the same on LTE1800, the same tests after turning on the external antenna, and finally the same tests on Auto, the ODU should then aggregate the LTE2600 + 1800 bands with BTS-A Śmigiel-Farna 15 because I assume that you live in this town, generally it's Plus, so it won't be crazy.

OKAY. Can you tell me how to do these tests? My computer is currently connected by cable. As I wrote, the computer is older, no wifi card. I can connect the card via bluetooth and then it works via wifi, but now I have disconnected the card. How to create an access point - I'm green in this topic....

Okay, it's gonna take a while 'cause I gotta run a little bit

Do not connect your computer via WiFi, because it will only get worse. The cord is the best. How to perform full tests wrote you colleague Matek. You do a quick bandwidth test on your computer by going to speedtest.net or a similar website.
Do not mix WiFi with LTE, they are two completely separate things. First, you do LTE tests while connected to the cable and select the optimal parameters (e.g. with or without an antenna). When the connection to the public network works optimally, only then do you provide access to this connection to customers. You connect your clients by wire to the router or via WiFi by installing the appropriate number of access points at home. You measure the WiFi signal level at home with a program on your phone (e.g. WiFi Monitor). WiFi signal level should not be lower than -70dBm.
How to configure Asus as an AP you must read in the manual.

Below is the data I somehow managed. Maybe they can help solve the problem

The LTE status with the antenna on and off is on the machine

I did two speed tests and they varied: PING 29ms, Download 62.66 - 61.30 Mb/sec, Upload 15.38 - 14.46 Mb/sec

LTE signal parameters are ok. Speed test is also a plus and such a router. You can also try to switch the band to another (depending on what is on the transmitter) than 1800MHz and do the test. However, it will not be much better, 60Mbps is a decent result.
Now you need to clean up your internal network. Place the AP, connect it with a makeshift cable to the router and measure the signal level in the rooms. Choose the best location for the primary router and secondary AP.

Unfortunately, ODU-IDU300 from Plus or Cyfrowy Polsat is equipment below every category. Because I still have a year of contract, I dragged the cables from the router and forgot about the wi-fi - greetings
