FAQ
TL;DR: Enable 2CC CA on Huawei B525 by selecting two bands; sites with 3–4 LTE bands work best; "Aggregation should turn on in the Auto setting." Use HManager to force LTE2600+1800 and watch LTE+ during a speed test. [Elektroda, matek451, post #17797626]
Why it matters: This FAQ helps Huawei B525 owners quickly enable and verify 2‑band aggregation for faster, steadier LTE on Play and similar networks.
Quick Facts
- B525 aggregation: use two bands (2CC), typically LTE2600 + LTE1800; skip LTE800 for CA. [Elektroda, matek451, post #17797670]
- CA indicator shows as “LTE+” in HManager and only during active data. [Elektroda, matek451, post #17797670]
- LTEWatchH cannot force or confirm specific CA combos; verify CA in HManager. [Elektroda, matek451, post #17797886]
- CA can auto‑enable in router Auto mode; you can also select two bands manually. [Elektroda, matek451, post #17797626]
- Reported Play site bands in this thread: LTE2600 / 2100 / 1800 / 800. [Elektroda, dzik211, post #17797643]
How do I enable 2-band aggregation on a Huawei B525?
Open HManager and select LTE2600 and LTE1800 together. B525 supports 2CC CA on these bands. CA shows as LTE+ only under load. Run a speed test to trigger it. “Aggregation shows as LTE+ and works during active data transmission.” [Elektroda, matek451, post #17797670]
What tools should I use to lock or test bands on the B525?
Use HManager or LTEWatchH to force and test bands one by one. Point your antenna at the target BTS first. Record DL/UL for LTE2600, LTE2100, and LTE1800 individually. Then try dual selection for LTE2600 + LTE1800. [Elektroda, matek451, post #17797670]
Can LTEWatchH force or verify a specific CA combo on B525?
No. LTEWatchH cannot force a specific aggregation or confirm LTE2600+1800 is active. Use HManager to verify CA. “LTE+ is displayed in HManager if it works.” Adjust antenna to avoid the wrong BTS if needed. [Elektroda, matek451, post #17797886]
Which band combination should I pick on Play with a B525?
Select LTE2600 + LTE1800 for 2CC CA. Test each band alone first, then lock both. Do not include LTE800 in aggregation on this router. Verify with a speed test while HManager shows LTE+. [Elektroda, matek451, post #17797670]
How do I know carrier aggregation is actually active?
Look for “LTE+” in HManager. CA only lights up during active data transfer. Run a speed test and watch the indicator. If LTE+ does not appear, recheck band selection and antenna aim. [Elektroda, matek451, post #17797670]
My router keeps attaching to the wrong BTS. How do I fix that?
Re-aim the directional antenna slightly to the right to avoid the Zakolejowa site. Then recheck bands in HManager. Confirm LTE2600+1800 and watch for LTE+ during a test. Small alignment changes can flip the serving cell. [Elektroda, matek451, post #17797886]
Which BTS should I aim at near Drogoszewo?
Aim at the Warszawska 1 site rather than Zakolejowa 23. LTE2600 from Warszawska worked well despite weak signal. 1800 and 2100 at the other site were overloaded by the railroad. [Elektroda, matek451, post #17797816]
My signal looks poor on all bands. Can CA still help?
Yes, if the site’s LTE2600 performs well, CA can still improve throughput. In this case, LTE2600 worked fine despite weak signal. Test each band, then enable LTE2600+1800 and run a speed test. [Elektroda, matek451, post #17797816]
Does the B525 support more than two bands at once (3CC/4CC)?
No. The B525 supports 2CC CA. Use HManager to select two bands if the BTS offers multiple LTE bands. “You can select two bands for aggregation of 2 CC CA.” [Elektroda, matek451, post #17797626]
Can I include LTE2100 or LTE800 in aggregation on B525?
Use LTE2100 for single-band testing only here. On B525, practical CA is LTE2600 + LTE1800. “We do not take LTE800 into account.” Confirm with HManager and a speed test. [Elektroda, matek451, post #17797670]
Will CA enable automatically, or do I need manual selection?
CA can enable itself in Auto mode if the BTS supports it. You can also manually pick two bands in HManager. “Aggregation should turn on in the Auto setting on the router.” [Elektroda, matek451, post #17797626]
How do I test each band’s performance before aggregating?
Force LTE2600, LTE2100, and LTE1800 individually and run DL/UL tests. Note speeds and signal metrics. Then select LTE2600+1800 together and retest while watching LTE+. This isolates the best pairing. [Elektroda, matek451, post #17797670]
Which LTE bands were available in the reported Play setup?
The user reported these Play bands on the serving site: LTE2600, LTE2100, LTE1800, and LTE800. Use HManager to confirm locally. Then target LTE2600+1800 for CA. [Elektroda, dzik211, post #17797643]
