Dear support, I've order 2x Elfin-EW11A from AliExpress. When connecting and powering the devices, the device is really slow (Wifi throughput) and web interface performance. The web interface is also looking completely different from the screenshot I can find on the internet (see attachments) Is there a way to flash the original firmware to the EW11A please? How should i proceed? Thank you!

使用PG41B-CA-M型485转4G模块时，根据文件《Modbus 应用20190801》4.1. 局域网 PC 直连测试部分，使用Modbus Slave和Poll进行调试时通讯端口如何填写？我使用IOT.Service找不到通讯端口配置的地方

PC与设备通过网线直连，无法ping通，也无法打开网页 使用IOT Service软件，全网可以搜索到，但是无法连接

之前都是用WAN配置设备 但是有一批设备只能用LAN配置设备
