FAQ
TL;DR: Field tests show B2368-66 peaks at 200 Mb/s off-peak, yet its "stupid PR will not replace professional knowledge" limits usability [Elektroda, matek451, post #17397666][Elektroda, matek451, post #17397511] Why it matters: buyers avoid costly hardware that under-delivers without tweaks.
Quick Facts
• Huawei B2368-66 = LTE Cat 12, 3×CA, but no band-lock in GUI [Elektroda, matek451, post #17397511]
• Play Internet 200 GB plan: PLN 70 / month; 300 GB: PLN 80 / month [Elektroda, Fixer24, post #17460151]
• B715 router street price: approx. PLN 300 new [Elektroda, Jeziorko, post #17446563]
• ODU power: 12 V, ≥1 A via PoE; stock PSU 12 V 2 A [Elektroda, BikeBarian, post #17611753]
• IDU acts as a switch + PoE injector, not a router [Elektroda, maxim2002, post #17617680]
What are the main differences between Huawei B2368-66 and B715?
B2368-66 is a two-box CPE: outdoor ODU (modem+router) and indoor IDU (Wi-Fi + PoE). It supports Cat 12, 3-band CA, but lacks band-selection and uses an omnidirectional antenna [Elektroda, matek451, post #17397511] B715 is an all-in-one indoor Cat 9 router; its WebUI and HManager allow manual band-lock and easier diagnostics [Elektroda, matek451, post #17397511]
Can I attach an external modem or antenna to the B2368-66?
No. The ODU contains the modem and integrated antenna; there are no RF ports. Users confirmed bypass attempts fail because the IDU is only a PoE switch [Elektroda, maxim2002, post #17617680]
Does the Play-branded B2368 have a SIM-lock?
Technically it carries a PLMN lock: only Play IMSIs register. Support claims “no SIM-lock”, yet cards from other networks cannot connect [Elektroda, pepisz, post #17418456]
What real-world speeds should I expect?
Users report 200 Mb/s at night on triple CA near a 400 m BTS [Elektroda, matek451, post #17397666] and 35 Mb/s down / 12 Mb/s up 2 km away with trees obstructing LOS [Elektroda, Jack84_PL, post #17640412] Average evening speeds drop to 25 Mb/s [Elektroda, Fixer24, post #17459819]
Which single-box router aggregates 1800 + 2100 + 2600 MHz under PLN 600?
ZTE MF980 (mobile) pairs with Xiaomi 3G router for USB tethering and 3×CA selection [Elektroda, matek451, post #17442117] Stationary option: Huawei B818 (Cat 19) retails ~PLN 600, supports the combo and SMA antenna ports (spec sheet, 2020).
How do I test the best operator before signing a contract?
- Insert prepaid SIMs into an LTE phone.
- Use the free Network Cell Info app outdoors to log RSRP/RSRQ and eNB IDs.
- Run speed tests at peak and off-peak times.
Record the top two performers; pick the one with stable ≥−90 dBm RSRP and consistent throughput [Elektroda, matek451, post #17397618]
Is the RJ-11 port on Play’s B715 VoIP capable?
The hardware supports GSM and VoIP, but Play’s firmware disables VoIP. Alternative firmware restores it [Elektroda, matek451, post #17462240]
What PoE specs are safe if I replace the IDU?
The ODU runs on 12 V over two pairs; draw is about 1 A. TP-Link 24 V injectors will damage it. Use a passive 12 V 2 A injector or the stock PSU [Elektroda, BikeBarian, post #17611753]
Why did my B2368 reset when I used a 20 m Cat 6 cable?
Longer or thinner cables drop voltage; the ODU brown-outs and reboots. One user saw 15 resets in 10 minutes with 20 m Cat 6 until reverting to the 10 m stock lead [Elektroda, Jack84_PL, post #17640412]
Are external LTE antennas legal in Poland?
Passive gain antennas are legal. Active GSM repeaters are prohibited. A user clarifies: “Any amplification or redirection … is strictly prohibited” refers to active devices, not passive antennas [Elektroda, matek451, post #17619486]
Quick 3-step guide: aiming a directional antenna for Play LTE-A
- Locate nearest multi-band BTS on map (LTE 800/1800/2100/2600).
- Mount antenna at roof height; sweep slowly ±15° while watching RSRP.
- Lock when SINR peaks; then test speed on each band via router diagnostics. “Ten degrees off can cost 20 Mb/s,” notes expert matek451 [Elektroda, 17831716]
Edge case: can the ODU work with third-party routers over Ethernet?
Yes, but only as a bridged connection: ODU handles NAT; your router sees a private IP. Advanced settings remain inaccessible; therefore VLAN, firewall or band-lock features stay limited [Elektroda, matek451, post #17617706]
