ZTE Xuntian BE3600Pro: What the Teardown, MLO, and 50-IoT Test Actually Show

ACWiFi disassembled the ZTE Xuntian BE3600Pro, whose label identifies it as model ZXSLCSR7011. This is a teardown and test report for that sample, not a guarantee that every BE3600Pro batch has the same board or firmware.¹

Visible hardware

The unit has one 2.5G port, three Gigabit ports, five external antennas, and a measured weight of about 450 g. Its power adapter is 12V/1.5A; ACWiFi measured 4.4 W with no network cable and 5.3 W while connected through the 2.5G WAN port. The flash chip on the rear of the board is W25N01KVZEIR, with 128 MB capacity.

The CPU is ZTE's ZX279129, a dual-core A53 part with an NPU described by the source as 4-core/64-thread and two integrated 2.5G MACs. Wi‑Fi uses the MT7990AN baseband/MAC: 2x2 2.4 GHz up to 688 Mbps at 40 MHz/4096-QAM, and 2x2 5 GHz up to 2882 Mbps at 160 MHz/4096-QAM. The RF chip is MT7976CN, with 2T2R on 2.4 GHz and 3T3R on 5 GHz; both bands have integrated FEMs. The 2.5G PHY is ZX279051.

An unpopulated pad near the PHY led the author to wonder whether a two-2.5G version might exist. That is a board-layout hypothesis, not a confirmed product specification. The large heatsink and two shields with thermal pads show a thermal-design choice, but they do not prove long-term temperature or reliability.

Forwarding, QoS, and dual WAN

With PacketMaster and 64-byte packets, WAN-to-LAN reached 1.488 Mpps, and the bidirectional test also reached 1.488 Mpps. With rate limiting/QoS enabled, the source still measured the full result under that test condition, so hardware forwarding did not disappear in the experiment.

ACWiFi also built two PPPoE WAN links on two Gigabit ports, used the 2.5G port as LAN, and enabled 1:1 load balancing. The result was 2.718 Mpps versus a theoretical 2.976 Mpps, a small drop, and the test indicated that the two WAN links could aggregate bandwidth. This is a lab result for one firmware and topology; it is not a promise for every multi-WAN implementation.

Wireless and MLO

ACWiFi used its K point and four phones for a quick comparison. The ZTE firmware was V1.0.0.2B3.8000; the Qualcomm Xiaomi BE3600 used as a comparison was on 1.0.87. Both routers used 20 MHz channel 11 on 2.4 GHz, 160 MHz channel 44 on 5 GHz, and MU-MIMO when supported.

The signal test used an AX200 client at points E, F, G, and H, recording for three minutes at each point. Xiaomi was slightly stronger on 2.4 GHz at several points, while 5 GHz was broadly similar. The speed tests averaged six runs per position with AX210, WCN6856, WCN7851, and Intel BE200 adapters; ZTE was generally faster on 5 GHz, while 2.4 GHz varied by client and location. I treat these charts as room-specific comparisons, not a universal coverage ranking.

The router defaults to beamforming and 802.11k/802.11v, but MU-MIMO is disabled by default; the firmware provides a switch to enable it.

The source identifies STR as the MLO mode that produces aggregation. The two clients mentioned are Qualcomm WCN7851 and MediaTek MT7927. Because BE3600Pro has only a 2.5G network link, combining 160 MHz 5 GHz with 40 MHz 2.4 GHz can hit the Ethernet ceiling. ACWiFi reduced 5 GHz to 80 MHz to make the aggregation visible; MT7927 reached 1546 Mbps and WCN7851 reached 1578 Mbps in that setup.

IoT-client and app tests

ACWiFi powered on 50 2.4 GHz smart plugs that already stored the acwifi SSID. After roughly 15 seconds, all 50 joined; the backend list showed 51 terminals when one PC was included. Repeated on/off control through the 50 switches also completed smoothly in that test.

The ZTE Smart Life app can add the unit as a new router or as a Mesh extender. The extender path is not entirely automatic: the instructions require pressing WPS for about two seconds. The app also exposes network, speed-test, and parental-control screens; those demonstrate management features, not a substitute for throughput or roaming measurements.

Reading the conclusion correctly

Within the published tests, BE3600Pro has enough 2.5G forwarding capacity for the basic path, MLO can exceed 1.4 Gbps with compatible clients, and the access point handled a large group of IoT devices quickly. I would still check thermals, dual-WAN stability, client compatibility, and firmware behavior before making it the main router.

The teardown does not measure long-term reliability, every SFP/transceiver scenario, aggregate multi-stream throughput, firmware security, or OpenWrt support. The empty pad also cannot prove a two-2.5G product revision. ZTE and MediaTek details above are tied to ACWiFi's sample and test conditions.
