24 (((
25 (((
26 The LPS8v2 is an (% style="color:green" %)**open-source LoRaWAN Gateway**(%%). It lets you bridge LoRa wireless network to an IP network via (% style="color:green" %)**WiFi , Ethernet or Cellular Network**(%%) (via Optional 4G module). The LoRa wireless allows users to send data and reach extremely long ranges at low data rates.
27 )))
28
29 (((
30 The LPS8v2 is fully compatible with LoRaWAN protocol. It supports different kinds of LoRaWAN Network Connections such as: (% style="color:green" %)**Semtech UDP Packet Forwarder, LoRaWAN Basic Station, ChirpStack MQTT Bridge**(%%), and so on. This makes LPS8V2 work with most LoRaWAN platforms in the market.
31 )))
32
33 (((
34 LPS8v2 also includes a (% style="color:green" %)**built-in LoRaWAN Server and IoT server**(%%), which provide the possibility for the system integrator to deploy the IoT service without cloud service or 3rd servers.
35 )))
36
37 (((
38 Different countries use different LoRaWAN frequency bands. LPS8v2 has these bands pre-configured. Users can also customize the frequency bands to use in their own LoRa network.

650 == 8.1  I can't log in to the built-in Server TTN Stack which shows '**Login failed**'. ==
651
652
653 [[image:image-20220920135918-1.png]]
654
655
656 This is caused by the inconsistency between the built-in TTN-Stack domain configuration and your login URL.
657
658 By default, ttn-stack uses the gateway's domain name for URL resolution, but in some networks, they prefer to resolve IP-v4 addresses.
659
660
661 So you can change the domain name of the TTN-Stack configuration to the IPv4 address.
662
663 **Click the update URL button to configure the URL with the current eth port address.**
