The ZBT Z8102AX is a useful first sample, but the next step should be stronger: Wi-Fi 7, a more powerful four-core platform, better firmware clarity, improved packaging and a more stable pricing policy. The goal is not just another 5G router, but a better configured OpenWrt-based prosumer device.

Buying a 5G OpenWrt router with older firmware can make sense, but only under the right conditions. The ZBT Z8102AX shows both sides clearly: the hardware is useful, the modem works, and the router stayed stable in testing, but OpenWrt 21.02, weak packaging and unclear upgrade paths require a careful buying decision.

The ZBT Z8102AX makes a solid first impression as a slim black metal 5G OpenWrt router with multiple antenna connectors, dual-SIM slots, USB, LAN/WAN ports and a practical accessory set. The hardware feels useful and serious, but the packaging is clearly the weak point.

The ZBT Z8102AX is a dual-SIM 5G OpenWrt router, but dual-SIM hardware alone is not the same as intelligent failover. The router recognizes the SIM and connects successfully, but automatic switching, modem recovery, signal-based decisions and clean failover logic still need deeper testing.

The ZBT Z8102AX uses a Quectel RM500U-EA modem for 4G and 5G connectivity. In the first practical test, the router connected successfully to o2 Germany with LTE Band 3 and NR n28. The modem works, but deeper diagnostics such as RSRP, RSRQ, SINR, band locking and cell behavior still need proper testing.

The ZBT Z8102AX runs a vendor-modified OpenWrt 21.02 build with kernel 5.4.246. In practical testing, the firmware worked successfully and kept the router stable for several days, but the old base raises important questions about security, modem control, upgrade paths and long-term maintainability.

The ZBT Z8102AX is an unusual 5G router with an OpenWrt base, a dual-SIM concept, and a Quectel RM500U-EA modem. In testing, it shows clear strengths in flexibility, interfaces, and mobile connectivity, but also the typical weaknesses of a vendor-modified OpenWrt build.
