[Solved] Title: Experiencing Slow Internet with Plus (Cyfrowy Polsat) - Router Issue or Operator Fault?

Best answers

How can I tell whether my slow Plus (Cyfrowy Polsat) internet is caused by the router/modem or by the operator/network?

Your slowdown is more likely caused by an overloaded Plus LTE base station and weak signal quality than by the router itself [#17518534][#17520999] The speedtest showing download lower than upload, together with low upload/signal levels, points to BTS congestion and poor reception; on that basis there is no reason yet to replace the router [#17518534] Since the modem is a Huawei E3372s-153 HiLink used through a DWR-116, connect the modem directly to the computer and retest, but expect only a small change if the network is the real bottleneck [#17520293][#17520303][#17520311] The next step is proper diagnostics: check the modem’s 192.168.8.1 page, read signal parameters and the BTS CID, and use LTEWatchH or E5186 Toolbox to test LTE1800, LTE900, and LTE800 one by one [#17520344][#17520425] Compare speed and signal results for each band and identify which nearby BTS you are actually attached to; in this case the nearby Plus sites were listed as Kościuszki 289, Jankego 123, Boya 34, and Kaczeńców 8 [#17520425][#17520999]

    Hello, for some time I have internet in Plus (Cyfrowy Polsat) once it walked beautifully, but for a few months it started to slow down (the speedtest.net test result below (if I can paste it)), besides, the 32 mb file is downloaded about 25 minutes. I have the impression that maybe it's not the operator's fault, but, for example, the router, maybe something else can be done, somehow check it ...
    Thank you in advance for your response :D

    And on what basis do you think that it is not the fault of the worst mobile operator but the router? What equipment do you have, what is the location?

    How do you think he has a problem like you? So far, it was shown by the speedtest from Plus, where DL is lower than UL, so it indicates that BTS is overloaded. In addition, a low UL level indicates poor signal performance. We do not know if this connection is LTE or 3G, in addition to which LTE / 3G band. on the basis of speedtest there are no grounds for replacing the router yet. You should perform professional signal diagnostics, find out the location of the nearby Plus BTSs, and the bands on which they operate. check which one it connects to. the type of equipment it has is important, the CP offer included several LTE and LTE-A routers, stationary and mobile, router + LTE modem sets and additionally 3 more IDU-ODU versions.

    Hello, I have a DWR-116 router, and I did not mean that it was our fault, not the operator, but I wrote that it was possible and asked if it could be checked somehow. I can not substitute another router. And as for BTS, I'll find out later.

    The modem is responsible for the LTE connection, not the router, this weak set from Plus? If so, the E3372s-153 should be in the HiLink version, i.e. after switching to the USB of the computer, it is managed via the 192.168.8.1 page. Do you have one? You don't learn anything because it won't do anything anyway. Give me the locations better. And of course, don't look for any other router, don't take such advice seriously. Answer the questions about your modem and location. Necessary to perform the appropriate tests.

    I live in the south of Katowice, so I can put the modem into my computer and use it like that, but it hardly helps at all, as I wrote above.

    Katowice is a big city when I don't have a glass ball to check where you live. Enter the street, you need at least an approximate location here. You were to check if the modem is HiLink and if you manage it via the 192.168.8.1 page after inserting it into the computer's USB, further steps depend on it, if HiLink you can check the signal parameters, LTE band, eNB, CID of the BTS you use in Plus. Additionally, do speedtest and show the result.

They will show the CID of the BTS you are using and the signal parameters. you can force LTE1800, LTE900 and LTE800 in the programs one by one. force one by one, show screenshots of them. on every speedtest. The closest BTS Plus with LTE1800, LTE900aero2 and LTE800Sferi (2 more months) is Kościuszki 289, on BTS at Jankego 123 only LTE1800. other BTSs are Boya 34 (LTE1800) and Kaczeńców 8 (LTE1800, LTE900).

    BTS on Kościuszko 289 PSP, LTE1800 aero2 from it, signal sufficient but very low SINR which proves that the BTS is overloaded. What does speedtest look like now because there is a tragedy in the evening, you showed it earlier. As predicted, Plus / CP in Katowice is the bottom, the worst mobile operator has been doing nothing with the network for years. On BTS, he only added LTE900 with 5MHz band, but this is an apparent modernization because it replaces LTE800Sferii, LTE900 works usually slowly but check this band. Click Frequenzband + and from the expanded bands select LTE900 and then LTE800 and check DL / UL and LTEWatchH show for them. Do not count on much, in Plus this operation of the Internet is the norm. it is possible that other LTE1800aero2 BTSs are less clogged, but this will have to be checked.

FAQ

TL;DR: How do I fix slow Plus/CP internet? Often it’s tower congestion; LTE900 uses 5 MHz, and “BTS is overloaded.” Use Huawei E3372 HiLink at 192.168.8.1 with LTEWatchH to lock LTE1800/900/800 and compare. [Elektroda, matek451, post #17520999]

Why it matters: This FAQ helps Plus (Cyfrowy Polsat) users with Huawei E3372/DWR‑116 quickly separate operator congestion from equipment issues so they can act fast.

Quick Facts

Is my slow Plus/CP LTE due to the router or the network?

Focus on the modem and the network. The Huawei E3372 handles the LTE link, not the D‑Link DWR‑116. Swapping the router alone rarely affects RF quality or tower congestion. Expert note: “The modem is responsible for the LTE connection, not the router.” Validate by testing bands and BTS before buying hardware. [Elektroda, matek451, post #17520344]

How do I check if my Huawei E3372 is HiLink and access it?

Insert the E3372 into a PC’s USB port. Open 192.168.8.1 in a browser. If the web UI loads, you have the HiLink variant and can manage the connection there. Use that access with tools for diagnostics. [Elektroda, matek451, post #17520344]

How can I see which BTS and band my modem is using?

Use LTEWatchH or the E5186 Toolbox. Connect to 192.168.8.1 and read the LTE band, eNB, and CID. These identify the serving cell and frequency. After each change, run Speedtest and capture screenshots to compare results. [Elektroda, matek451, post #17520425]

How do I lock my E3372 to LTE1800/LTE900/LTE800 for testing?

Lock bands to compare performance.
  1. Open LTEWatchH and connect to 192.168.8.1.
  2. Click Frequenzband, select LTE1800, apply, then run Speedtest.
  3. Repeat for LTE900 and LTE800, noting RSRP, RSRQ, SINR, and results. This isolates congestion versus weak coverage. [Elektroda, matek451, post #17520999]

Why is my download slower than upload on Speedtest?

That pattern signals a congested base station. Expert note: “DL lower than UL indicates that BTS is overloaded.” If upload is also low, the signal path is weak. Check SINR and RSRP, try another band or tower, then retest. [Elektroda, matek451, post #17518534]

What does low SINR mean for my speeds?

Low SINR reveals interference and contention. Even with sufficient signal, throughput can collapse under low SINR. In this case, very low SINR proved tower overload. Improve SINR by changing location, orientation, or band, then retest. [Elektroda, matek451, post #17520999]

Will plugging the E3372 directly into my PC speed things up?

Direct USB testing removes router overhead. In this thread it improved speed by only about 3%. That points to tower congestion or RF issues, not router limits. Keep testing after band locks to confirm the bottleneck. [Elektroda, barteku2006, post #17520311]

Should I replace my D‑Link DWR‑116 router to fix slow LTE?

Replace the router only after diagnostics. The router does not create or fix RF link quality. “The modem is responsible for the LTE connection, not the router.” Test bands and serving cells first. Upgrade only if signal work is required. [Elektroda, matek451, post #17520344]

Why is Plus/CP’s LTE900 often slow even with good signal?

LTE900 uses a 5 MHz channel, which limits capacity. It often replaced LTE800 and tends to be slower than LTE1800. You can test LTE900, but expect lower throughput during load. Prefer LTE1800 if that cell is less congested. [Elektroda, matek451, post #17520999]

Which Plus/CP BTS should I test near Szymanowskiego, Katowice?

Try these sites: Kościuszki 289 (LTE1800, LTE900 Aero2; LTE800 Sferia was temporary), Jankego 123 (LTE1800), Boya 34 (LTE1800), and Kaczeńców 8 (LTE1800, LTE900). Lock each band, then run Speedtest and save LTEWatchH screenshots. [Elektroda, matek451, post #17520425]

How should I test properly and share results?

Use a consistent method. Lock one band, note eNB/CID and signal metrics, and run Speedtest. Repeat for other bands and, if possible, other BTS. Share LTEWatchH and Speedtest screenshots for each case to isolate congestion from coverage issues. [Elektroda, matek451, post #17520425]

When is it time to switch operators or plans?

If every band and nearby BTS shows poor evening downloads, the network is overloaded. The expert flagged Plus/CP locally as chronically congested. If tests confirm that, choose a carrier with better capacity at your address and retest before committing. [Elektroda, matek451, post #17520999]
