UPC: Correct Downstream & Upstream Parameters - Power Levels, Signal to Noise Ratios

Hello,

Mode with UPC shows the following parameters. Are they correct?


Thank you in advance for your help

Hello,

I have had problems with the internet for 3 months, today he was an internet technician again. We decided to replace the router with a new one, but I have some doubts about the internet signal. Please, assess whether the parameters are correct at a 120MB / S link.
greetings

I have a vectre in another location and everything works fine and the parameters are completely different, but I can't interpret them.

Vectra - Upstram too high, UPC - Upstram unequal, too large discrepancies

Hello, I will stick to the topic if you allow. I have an EPC3928S cable modem, the modem often disconnects and reboots. The cord from the cage goes directly to the modem without any splitters. A computer connected to the modem with a cable and a tablet via Wi-Fi. Here is the data from the modem

Downstream Channels


Power Level: Signal to Noise Ratio:
Channel 1: 10.7 dBmV 44.6 dB
Channel 2: 10.5 dBmV 45.4 dB
Channel 3: 10.0 dBmV 44.6 dB
Channel 4: 10.9 dBmV 45.5 dB
Channel 5: 10.1 dBmV 45.3 dB
Channel 6: 11.4 dBmV 46.4 dB
Channel 7: 10.5 dBmV 46.2 dB
Channel 8: 11.3 dBmV 46.3 dB


Upstream Channels


Power Level:
Channel 1: 43.5 dBmV
Channel 2: 43.5 dBmV
Channel 3: 45.0 dBmV
Channel 4: 44.5 dBmV

Are these levels correct or is it because of them that the connection may be disconnected. The Internet reaches 200Mb down and 40Mb up.

The modem restarts, all controls go out, then some of them turn orange and the modem continues to boot. Better to suppress the signal more or less? I also noticed one regularity that the modem "must" restart once a day, sometimes at a similar time, or it may have the provider set up somehow. After the work of other modems in the network, I see that they work for several days, while the one that I have even longer than 24 hours without a restart did not work.

Czy coś jeszcze należyz tym zrobić czy tak zostawić ??

Hello. Let me refresh this topic. For several days I have had big problems with the Internet at UPC. I have a 250 Mb / s connection, but the average speed it gets is 100-130 Mb / s, during the day it also often drops to 6 -10 Mb / s. The connection is cable, the modem is Technicolor TC7200U. The problem is that the modem only logs on 4 downstream channels instead of all 8 and hence cannot reach full link speed. It looks like:



I had a visit from a service technician from UPC, who, however, was unlucky when the modem was logged on to 8 channels and it was fine. But an hour later everything returned to "normal" from the last few days.

Every now and then I restart the modem or restore its factory settings. Sometimes it will jump to all 8 channels, but then I have speeds of about 10 Mb / s. For example, recently it looked like this:



So everything is OK, but the speed measured by the speed test was like this:

Could someone take a look at these downstream values and write down what could be causing the problem?

Strange things are happening. Currently, the modem jumped on 8 channels, it looks like this:



Are these parameters good? Because the test in speedtest.net came out like this: http://www.speedtest.net/result/5309720198.png

So it is not very interesting, to put it mildly. So it may be that despite the fact that the modem works on 8 channels, I will have lame speeds because something is messed up in my building? Of course, I will report it to UPC again, but knowing life, they will underestimate the problem again.

I would like to believe in their good intentions The problem was already reported once, as I wrote, I had a service visit a few days ago, but the gentlemen said that nothing bad is happening, that there is supposedly some modernization of the network in my estate and until yesterday it was supposed to be repaired. Let's say I was unlucky, because they dropped in just when the link started working as it should, but what kind of technician who will not check even the condition of the wiring on the cage, if I tell him that I have had a problem for a dozen or so days, and that it has just improved for a while? doesn't mean anything ... But okay, thanks for your help, I'll be tormenting them until I get through

A little update of this thread. I had a second visit by a service technician. The problem has been confirmed - the modem logs on only to 4 DS channels, so I do not reach the full speed of the link. That's it. The service technician was unable to determine exactly what was causing the problem. Apparently there is some serious failure somewhere in my neighborhood and all he suggested was writing a complaint. I suspect that I will have a longer fight with them, but we will live, we will see.

Ok, thanks for the suggestion, it really makes no sense to pay for the connection, which only in theory has 250 Mb / s. But I still have a request. Could you take a second look at the downstream parameters?



I'm a complete layman, but I think these numbers are fine. I don't know what's going on here, but for 2 days the modem has been logging in for 8 channels. At speedtest.net, it comes out 230-240 Mb / s, which is how it should be. Well, but I have real transfers when downloading at the max level. 4-5 MB / s, which is 5 times slower than theoretically I should be pulling. Of course, I download a test via cable from fast servers such as ftp.atman.pl. Unfortunately, this link is still blocking something.

It seems to me that it is still too slow. I am attaching a print screen from JDownloader.



Anyway, I remember that earlier I 'pulled out' full speed even when downloading a single file. Such slowdowns have rarely happened, and certainly not on these high-speed servers. Well, but that's it with the previous contract (I had 120 Mb / s and average download speeds of 12-13 MB / s).

Thank you for your willingness to help. I looked through the linked topic in detail. A problem similar to mine, indeed. The first thing I did was to install the Auslogics BoostSpeed program, which helped the author of that topic. For me, he detected some incorrect entries, but fixing them did not help. Installing Fiber Power Optimizer from UPC did not help either. I tried to download this Axel for Windows, but the link from that topic has already expired and the google version does not work for me (on Win 10).

As for the other issues described there - I have an integrated network card, it supports 1 Gbit, in the options I have "1.0 Gbps Full Duplex" turned on. Additionally, I reinstalled the network card drivers. It seems to me that I have nothing messed up in the system, moreover, for a while everything worked as it should, until these problems with logging in the modem appeared only on 4 channels. Just to be sure, I booted from a bootable USB Linux Mint. And there are also transfers at the level of max. 5 MB / s.

Today I visited a friend who has the FB 120 package from UPC and I tested myself for a while. And with him everything flashes quickly. Regardless of whether it downloads one file or several at a time, the transfers are practically maximum for such a link. For example, we checked ftp.atman.pl, one 5GB.dat file, browser download and 13-14 MB / s transfer without even a momentary slowdown. And for me, downloading the same file, the transfer does not exceed 5 MB / s, and the link is theoretically 2x faster. Anyway, I observed the same on "normal" sites, such as dobreprogramy.pl, instalki.pl or other such types with fast downloads. Well, my friend's files (of course downloaded individually) "fly" at maximum speed, and in my case, max. 6 MB / s. Even on such Youtube, it seems to me that you can see the difference in loading movies, even though I have a 2x faster connection. In any case, something is definitely wrong with me that this internet is "suffocating", although in various speed tests I have been reaching 230-240 Mbit for a few days.

I will wait another week, if it does not improve, I will write a complaint. Thanks again for your help.

And yet the fault with significantly underestimated transfers was with the system. A friend came to me with his computer and after firing it up, it turned out that everything works as it should. I don't know what changed there and when. I suspect that programs such as Vacuum Cleaner or CCleaner, which I have been using for some time, may have been mixed up in my system. In any case, after reinstalling Windows, I have download speeds above 20 MB / s. With ftp.atman.pl it "flies" 26-28 MB / s when downloading one file. So problem solved, I just hope UPC doesn't mess with these downstream channels anymore Thanks again for your help.
