Maximizing Internet Speeds on Huawei E3372 Modem with TP-Link Wr740 Router

Best answers LABEL_AI_GENERATED

How can I increase the internet speed on a Huawei E3372 modem, and can my TP-Link WR740 router help?

To get higher speed, force the Huawei E3372 to use LTE only instead of 3G, because the thread indicates your modem is a HiLink unit and is currently falling back to 3G [#16800028] Log in at 192.168.8.1 and, in the LTEWatchH/app interface, use the frequency-band control to try LTE bands 800/1800/2600 one by one [#16801277] If LTEWatchH does not see the modem, something is configured incorrectly; one reply notes that the modem should work with that program and that changed admin credentials may need to be entered [#16801312] The TP-Link WR740 is considered useless for improving this setup, so it is not the place to expect a speed increase [#16799748]

    A friend gave me the Huawei E3372 modem. After logging in there is a 3G connection with Orange. Modem software version: 22.200.05.00.159 Speeds around 0.5 to 3.5 Mbps The network settings only have:
    Network Settings
    Network
    LTE network support: On
    Network Search
    Automatic mode
    Is there any way to set higher internet speeds?
    I also mean Wi-Fi, I only have a TP-Link Wr740 router from Gargoyle.
    I would be very grateful for your help

    Is the modem HiLink or normal? Like Hilink, download it link , log in as to the configuration panel and give screenshots. Provide location. TL-WR740 is useless.

    I'm supposed to check if it's Hilink? I log in through 192.168.8.1

    HiLink you have. Download the application and set only LTE, because you have a strong 3G signal and LTE is missing. Give me a screenshot.

    You have Częstochowa in your profile, there you should not have problems with LTE.

    Enter the login details on page 192.168.8.1 and next to the frquency band you have such a plus, and there select the bands 800/1800/2600 in turn. Give screenshots.

    You are doing something wrong, try again, this modem works with this program. If you have changed the standard admin / admin password, you must enter it in LTEwatchH, change from default to password and enter the password under IP.

    I don't know what's going on, the browser logs in without a password, unfortunately LTEwatchH can't see the modem. Huawei E5186 Toolbox connects to the modem but I cannot change the band

FAQ LABEL_AI_GENERATED

TL;DR: For Huawei E3372 HiLink, lock LTE-only and test 3 LTE bands (800/1800/2600); “select the bands 800/1800/2600.” [Elektroda, makosuu, post #16801277]

Why it matters: This stops 3G fallback and can turn sub‑Mbps results into usable broadband for streaming and work.

Quick Facts

How do I tell if my Huawei E3372 is HiLink or classic (stick) mode?

If you manage it via a browser at 192.168.8.1 without dialing software, it’s the HiLink variant. That web UI signals router‑style firmware. [Elektroda, anemon, post #16799784]

How do I force LTE-only so the modem stops falling back to 3G?

Use the management app and set network mode to LTE only. This prevents the device from locking to a strong 3G signal when LTE is available but weaker. [Elektroda, makosuu, post #16800028]

Which LTE bands should I try first on the E3372?

Start with LTE bands 800, 1800, and 2600 MHz. Cycle each band during tests to see which gives the best signal and throughput. [Elektroda, makosuu, post #16801277]

Where in the interface do I change bands on a HiLink E3372?

Log in at 192.168.8.1. In the frequency band section, click the plus icon and select 800/1800/2600 in turn. Save and test each band. [Elektroda, makosuu, post #16801277]

LTEwatchH can’t see my modem—what should I check?

Ensure LTEwatchH uses your current admin password. If you changed admin/admin in the web UI, set that same password in LTEwatchH under the modem’s IP. “Change from default to password.” [Elektroda, makosuu, post #16801312]

Is my TL-WR740 router limiting my internet speed?

Yes, it can be a bottleneck. As one expert put it, “TL-WR740 is useless.” Consider a more capable LTE router or firmware that handles USB modems better. [Elektroda, makosuu, post #16799748]

What speeds should I expect before any tuning on this setup?

The thread reports about 0.5–3.5 Mbps on Orange 3G before forcing LTE or band selections. Use this as a baseline when measuring improvement. [Elektroda, anemon, post #16799676]

Huawei E5186 Toolbox connects, but I can’t change bands—why?

Users observed that E5186 Toolbox may connect but not manage E3372 band locking. Use LTEwatchH or the HiLink web UI for band selection instead. [Elektroda, anemon, post #16801357]

Do I need to share my location when asking for help with LTE tuning?

Yes. Helpers use location to infer nearby LTE coverage and suggest better bands or towers. A city with broad LTE should not face LTE access issues. [Elektroda, makosuu, post #16800028]

Is it normal to log into the modem without a password?

Some units allow immediate access if the default hasn’t been set. If you later set a password, remember to mirror it in tools like LTEwatchH. [Elektroda, anemon, post #16801357]

How do I download the recommended utility from the shared link?

Open the link, wait five seconds, then click “Skip ad” in the top-right. This bypasses the interstitial and starts the download. [Elektroda, makosuu, post #16801214]

The modem only connects to 3G—what should I try first?

Set network mode to LTE only and retest. Strong 3G can mask weaker LTE unless you force LTE. Then try bands 800/1800/2600. [Elektroda, makosuu, post #16800028]

Quick how-to: lock bands on Huawei E3372 HiLink

  1. Log in at 192.168.8.1 with your admin credentials.
  2. Open frequency band settings and click the plus icon.
  3. Select 800, test; then 1800; then 2600, saving each time. [Elektroda, makosuu, post #16801277]

What is HiLink on Huawei modems?

HiLink is firmware that exposes a web interface at 192.168.8.1, acting like a mini‑router instead of a dial‑up modem session. [Elektroda, anemon, post #16799784]

Edge case: Why does LTEwatchH still fail after I set the password?

If tabs are empty or the modem isn’t detected, restart the utility and verify the IP and password fields again. Enter the changed admin password explicitly. [Elektroda, makosuu, post #16801312]

Expert tip: why cycle bands individually?

Different bands vary by coverage and load. Testing 800, 1800, and 2600 separately finds the best balance for signal and speed at your spot. [Elektroda, makosuu, post #16801277]
