Scenario Constraints
The H138-380 is a household wireless broadband access product designed for use in scenarios
with relatively few network access devices and relatively low network reliability requirements,
such as homes or small office and home offices (SOHOs).
The H138-380 is not an enterprise-grade product. It cannot be used by medium- or large-sized
enterprises or in scenarios with high network reliability requirements, such as banks,
securities agencies, traffic control, and communications device backhaul.
The H138-380 has the following constraints:
When the IP Pass-Through mode is enabled, the FOTA function cannot be used.
When the L2TP/PPTP VPN client function is enabled, the throughput performance will
slow down.
A maximum of 128 devices can be connected to the Wi-Fi in theory; the actual number of
devices that can be connected and served depends on actual conditions.
