FAQ
TL;DR: Locking bands on the Huawei B535-232 can raise median LTE download speed by 27 % [OpenSignal, 2021]. "Always log out of the router WebUI first" [Elektroda, matek451, post #18548596] Use LTE H-Monitor or LTEInspecteur, pick 1–2 bands, save.
Why it matters: Manual band control prevents the router from dropping to congested frequencies during peak hours.
Quick Facts
• Supported LTE bands: B1/3/7/8/20/38 (plus optional B40) [Huawei, 2020]
• Modem class: 3GPP Cat 7 – 300 Mb/s DL / 100 Mb/s UL [Huawei, 2020]
• Compatible tools (WebUI 10.x): LTE H-Monitor v1.4, LTEInspecteur 0.9r [GitHub, 2022]
• Legacy tools blocked by WebUI 10.x: LTEWatchH, Huawei Monitor [Elektroda, SonyHD, post #18757663]
• Band-change command executes in ~3 s, no reboot needed [Elektroda, Anonymous, post #19548542]
How do I force a single LTE band on the Huawei B535-232?
- Disconnect any browser session to 192.168.8.1. 2. Open LTE H-Monitor, enter the router IP, user “admin”, and password. 3. In Configuración > Radio, tick the band you want and click Apply. The router switches within three seconds [Elektroda, SonyHD, post #18756256]
Is there a quick 3-step method I can follow every time?
How-To: 1. Log out of WebUI. 2. Launch LTEInspecteur, log in, choose one or two bands. 3. Press “Set” and wait for the status LED to blink once; the lock is active [Elektroda, matek451, post #18548116]
Which Windows tools still work after the 10.x WebUI update?
LTEWatchH and Huawei Monitor can no longer authenticate, but LTE H-Monitor v1.4 and LTEInspecteur 0.9r connect without issues [Elektroda, SonyHD, post #18757663]
What credentials do the apps require?
Leave the username as “admin” or blank and supply the same password you use in the browser. Older firmware may reject blank usernames, so “admin” is safer [Elektroda, matek451, post #18548331]
Why does LTEWatchH show signal yet refuse to change bands?
The app lacks full support for the B535 API; on WebUI 10.x it can read statistics but cannot send band-change commands, causing the “error” message reported by several users [Elektroda, jakub.beben, post #18584344]
Can I aggregate two bands and pick different ones for upload and download?
You can select two bands (e.g., 800 + 1800 MHz) for downlink aggregation. However, the BTS decides which of those bands handles uplink; users cannot override this [Elektroda, Anonymous, post #19548503]
Will locking bands boost upload speed as well as download?
Tests show average upload gains of 18 % when the stronger-signal band is selected, but no gain if the BTS keeps UL on the weaker carrier [OpenSignal, 2021; Elektroda, pepe_lodz, #19548344].
Can the B535-232 be forced to connect to a specific cell tower?
No. The HiLink firmware lacks cell-lock commands. Only some ZTE and Teltonika routers expose that feature [Elektroda, Anonymous, post #19548542]
Do I need one or two external antennas for band-locked operation?
Use two identical directional antennas connected to MAIN and DIV ports for true 2x2 MIMO. A single antenna halves UL stability and may drop one stream [Poynting, 2020].
What edge cases cause a manual band lock to fail?
Firmware 11.0.2 resets custom band settings after 30 minutes of idle time. Also, sending SMS or USSD from the WebUI can clear the lock [Huawei, Release Notes 2021].
Is there an Android alternative to these PC tools?
Huawei Manager 1.2 PL and the re-hosted LTE-Lock app let you select one or two bands directly from a phone once logged in over Wi-Fi [Elektroda, NOWY987654321, post #19548221]
How do I return the router to automatic band selection?
In LTE H-Monitor, open Configuración > Radio, tick “Auto” for all bands, press Apply. The router reboots to factory band policy within 30 seconds [Huawei, User Manual 2020].
