The situation after replacing the set-top box with a new wifi premium box +

I would like to advise you on what can be done to improve the situation.

I have had NC + for years and I recently extended my contract and replaced the old set-top box with a new wifi premium box +, although I resisted the replacement for a long time.
Before replacing the decoder with the old one, I had the strength parameters about 85-90 and quality 78-82 on both antennas.
After replacing without touching anything strength is 99 and quality varies from 51 to 55.
Would it show that the new decoder is less sensitive or what?
The antenna installation is built on a 100cm parabolic platter, two LNBs mounted in the QUATRO Inverto BLACK Ultra 0.2dB type squint system and the MS-952 Terra 9-input 4-output multiswitch and 4 end subscriber sockets.
I do not remember how the previous decoder was configured, but in the new one I tried to set the antennas with Diseqc. Then I have a choice of LNB1 - LNB4. Unfortunately, in this configuration, the tuner does not want to download channels, considering that the antennas are incorrectly configured. It is only possible to configure the antennas in the "tone burst" option. Then LNB1 and LNB2 are available.
According to the instructions, the decoder works with diseqc 2.1, and the multiswitch is 2.0, so it shouldn't be a problem as I think. Additionally, the multiswitch has a tone burst option.
But regardless of the settings there is no signal from the Astra, so the channels end at about 650 (I don't remember exactly). In the old decoder, the reception from the Astra was trouble-free and there were about 900 channels.
What can be done about it.

As for the signal quality, this is normal. He shows 20-25% less. LNB1-HB, LNB2-astra and it should work.

OK, but the astra doesn't work. I tried on LNB2 and with the strength of about 98 the quality 0 and in this situation the decoder does not download channels, so I have to set the lack of the Astra to continue.

View manually search transponder with Astra 19.2 ° E 11186V. It continues.

When I get home I'll try, but I don't know how.
The decoder does not allow to save the configuration when it fails to pass the antenna configuration, and in the case of the astra it detects nothing. If I leave it like that, I don't allow anything else to be done. If I set astra = none, the configuration is saved, but only for HotBird.
All in all, I do not remember what is there on the Astra and whether it is worth watching, because the time is short recently, but since the installation has two LNBs, it makes no sense to turn off one satellite.
I also do not know why the decoder does not accept the configuration in the "with DiseqC" option.
I read somewhere on the net that NC + provides decoders with inefficient power supplies and that is why there are such problems with LNB control, although I do not know if this is true.

Since you have zero quality on the Astra, i.e. there is a problem with the antenna, specifically with a squint on the Astra.

Can you tell how to do it on this decoder?

I made another approach to antenna configuration. Unfortunately, I can't see how to manually search for channels.
The procedure in this decoder is simple and comes down to choosing for each of the antennas and for HotBird and Astra to define communication between the decoder and LNB.
In the case of asters, the quality is zero and leaving this setting will make it impossible to save the settings. To access Hotbirg's channels, you must set asters to none.
For the sake of clarity, I will repeat what I wrote in the first post. When replacing the decoder, the antenna installation was not moved, which means that both the antenna and the converters remained unchanged. Before replacing on the old decoder, channels from asters were available. I will not repeat myself about the signal quality.

You write yourself that you haven't watched asters for a long time. Maybe something just broke. Check if the strabismus does not move or the converter lid is not cracked.

I do not know. When I have access, I will see it.

Then I'll tell you. No way. The list of channels is imposed by the operator and it is not possible to program anything manually.
Unless some new soft has been released in the days, but I don't know anything about it.

Installation on the roof is fine. Converters are completely new because they were replaced last year, just like the multiswitch.
I did not actually watch specific astra channels, but shortly before the exchange I had over 900 channels. I know, because when the decoder was set to TVN, i.e. the first channel, moving the remote control button backwards set the last channel and it was over 900, I do not remember exactly. So the astra was there.
I do not know if this old decoder had greater sensitivity and it caught astra, because it catches 48 to 60% of the quality on Hotbird channels.

Just because it was number 900 does not prove that it was Astra. There was Astra at the time of configuring the previous set-top box and a list of Astra channels was downloaded that might not be receiving afterwards, even though they were on the list. You need to connect your decoder to another installation, or connect another decoder to your installation, or call a professional with a meter.

On Polsat, if you go back, it's over a thousand but Hotbird. But the arguments. These were supposed to be Astra 19.2 ° East programs and specific frequencies.

OKAY. I think I'm going to visit the roof, but it's cold for now. But by the way there were over 900, even if one of the last or several was not from asters. Now the decoder catches six hundred pairs, because the configuration of the antennas from the astra is turned off, so there is a difference.
