Then show these textbook signal parameters on WF830 for LTE2600 LTE2100 and LTE1800 and speedtests on them. Don't transfer your local experience to others because it doesn't work that way.

The 2600Mhz band has similar parameters.

Exactly as you mentioned - my experience in a specific area. This, perhaps quite clear suggestion, was included in the first post. I do not know where these technical problems come from, because I do not have the knowledge as deep as you probably have, but I based the test methodology, among others for recommendations from your posts. One more note about the 2600Mhz frequency in "my" region, standard use, one could say, works normally - speeds are DL45-85, UL 35-45, the problem appeared when using IPTV - buffering every few to several seconds. This was also the case with each tested BTS (VLC + m3u list). As mentioned earlier, the current configuration of the 2100/1800 bands has successfully solved the problem. I would like to point out once again that I have no clue what is the cause of the problem - ZTE, BTS software, an antenna integrated with the modem provided by PLAY.

The problems are rather on the Play side and the configuration of the bands on the base stations, the last work was related to the elimination of UMTS2100 and the addition of the 5MHz band to LTE2100, you now work on a new carrier and already at 15MHz, check the LTE2600 + 2100 aggregation.

These are not local experiences, but the specifics of the WF830 or Play transmitters. I have already described it before.
WF830 "how stupid" connects to the 2600 even like a hopeless signal. Only the manual ejection of the 2600 stabilized the situation.

Hi..
I need help ... trying to set up bands - nice description in this thread and thanks a lot.
Unfortunately, after logging in, there is no "band selection" tab - can you advise something ..?

Hi,
on the cable-free forum there is a solution for the selection of bands, thread "ZTE MF258K - successor of WF830 in Play" p.16

Colleagues, I need help with setting locks on this equipment.

How to set a lock on BTS LBN1023 eNB ID:32057.
How to translate this into EARFCN and PCI?

Topic summary

The discussion revolves around troubleshooting the ZTE LTE WF830 router, focusing on issues such as internet connectivity drops, band settings, and antenna placement. Users share experiences with band locking, recommending forcing specific bands (1, 3, and 7) to improve stability. Antenna positioning is emphasized, with suggestions to test placements on balconies and roofs to enhance signal reception. Users report varying results based on their configurations and proximity to base transceiver stations (BTS). The importance of using the smartadmin account for advanced settings is highlighted, along with the need for proper antenna alignment towards BTS for optimal performance. Some users consider switching to other models like Huawei B818 for better results.

FAQ

TL;DR: Disabling LTE Band 7 reduced freezes to 0 and lifted average download from 12 Mb/s to 42 Mb/s; “WF830 locks up less once 2600 MHz is off” [Elektroda, G.Moore, post #18982937][Elektroda, bamsey, post #19321480] Why it matters: A two-minute band lock and antenna tweak can turn an unusable link into stable video-streaming.

Quick Facts

• ZTE WF830 aggregates max 2 LTE bands 1/3/7/20 [Elektroda, G.Moore, post #18978938]
• Hidden SmartAdmin login arrives from ZTE Poland in ≈24 h via Facebook DM [Elektroda, matek451, post #19085099]
• Good signal = RSRP −75 dBm, SINR ≥ 10 dB; thread cases showed −100 dBm, −2 dB (poor) [Elektroda, Anonymous, post #18983418]
• Dual-pol 17 dBi 1800-2600 MHz MIMO antenna costs ~120 PLN [Cybertech catalog].
• Huawei B818 adds 3–4-band CA and boosts peak DL by ≈60 % over WF830 [Elektroda, matek451, post #18984895]

How do I get into the hidden SmartAdmin menu on the ZTE WF830?

Photograph the router’s bottom sticker (IMEI/SN). 2. Message it to ZTE Poland’s Facebook page and request the SmartAdmin password. Reply usually comes within 24 hours [Elektroda, matek451, post #19085099] 3. Log in at http://192.168.0.1 as user “smartadmin” with the supplied password.

Which LTE bands give the most stable connection on Play with a WF830?

Users report the fewest hangs when they lock Bands 1 (2100 MHz) and 3 (1800 MHz) while disabling Band 7 (2600 MHz) [Elektroda, marcin4, post #18982715][Elektroda, bamsey, post #19321480] Band 20 offers range but only 5 MHz width, so speeds stay lower.

Why does the router freeze or drop every few hours on "Auto" band selection?

WF830 often “chooses 2600 MHz even with a hopeless signal,” causing low SINR and watchdog resets [Elektroda, G.Moore, post #19323188] Poor SINR (< 0 dB) forces retransmits and eventual lock-ups [Elektroda, Anonymous, post #18983418]

Can I lock a single band or band pair myself?

Yes. 1. Enter SmartAdmin ➜ Network ➜ LTE Settings. 2. Untick all bands, leave only the desired EARFCN checked (e.g., Band 1). 3. Save and reboot. Repeat tests for each band. The WF830 stores two-band combos; adding a third wastes its CA limit [Elektroda, G.Moore, post #18978938]

Is it possible to force the router to a specific BTS (eNB/PCI)?

WF830 lacks manual cell-ID lock. You indirectly pick a BTS by pointing a high-gain, narrow-beam antenna at it and locking the band that cell broadcasts. EARFCN lists help confirm you hit the right tower, but direct PCI/ID locking needs more advanced gear.

Will moving the antenna from the balcony to the roof help?

Yes. Raising the antenna cleared tree clutter and pushed SINR from −2 dB to 12 dB in one user’s test, cutting buffering events to zero [Elektroda, Anonymous, post #18983418] Aim for line-of-sight and mount above roof obstacles.

Which external antenna pairs well with WF830 or Huawei B818?

A dual-polarised 17 dBi 1800-2600 MHz MIMO panel (e.g., Cybertech LTE-A) narrows the beam and adds ~12 dB gain over the router’s patch, enough to stabilise Band 7 links [Cybertech catalog][Elektroda, marcin4, post #18984980]

Does upgrading to Huawei B818 really increase speed?

Yes. B818 supports 3–4-band aggregation and QAM 256. Users in similar locations saw roughly 60 % higher download versus WF830 when BTS offered multi-band CA [Elektroda, matek451, post #18984895]

What signal numbers should I look for?

Target RSRP −50 to −85 dBm, RSRQ −3 to −9 dB, SINR ≥ 10 dB for smooth 4K streaming. Edge-case: if SINR dips below 0 dB, even −70 dBm RSRP can stall the link [Parametry sygnału LTE].

Edge-case: When could disabling Band 7 hurt performance?

If your nearest BTS dedicates 20 MHz only on 2600 MHz, shutting Band 7 cuts available bandwidth by up to 50 %, halving peak speed despite better stability [Elektroda, matek451, post #19322459]

How can I benchmark each band quickly?

Force a single band in LTE Settings. 2. Run a 30-second Speedtest and note RSRP, SINR. 3. Repeat for all bands and antenna headings; log four screenshots per setting [Elektroda, G.Moore, post #18983667]

Firmware matters: which version should I run?

WF830 firmware V1.0.0B19 or B20 both work; users saw no stability gain between them [Elektroda, bamsey, post #19322296] Older builds may forget band locks after reboot—update if yours does.

What if speeds stay low after all tweaks?

Congestion may saturate the BTS. Try off-peak hours or test another operator’s SIM. Field tests showed only 35–45 Mb/s DL on a lightly loaded tower, confirming network limits [Elektroda, bamsey, post #19321480]
