-- Supported modems: Quectel, Sierra Wireless, Telit, Huawei, Fibocom
+- Dynamic kmod loading (`load_kmod.sh`)
+- Modem profile database (`modem_profiles.sh`)
+- Auto-detect with profiles (`detect_modem.sh`)
+- Supported modems: Quectel, Sierra Wireless, Telit, Huawei, Fibocom, and more
 - Band locking (`band_lock.sh`)
 - Diagnostics (`modem_diag.sh`)
 - Multi-protocol support (`modem_connect.sh`)

 # 5G-Modem-Support Enhanced
 ## Features
-- Dynamic kmod loading (`load_kmod.sh`)
-- Modem profile database (`modem_profiles.sh`)
-- Auto-detect with profiles (`detect_modem.sh`)
-- Supported modems: Quectel, Sierra Wireless, Telit, Huawei, Fibocom, and more
-- Band locking (`band_lock.sh`)
-- Diagnostics (`modem_diag.sh`)
-- Multi-protocol support (`modem_connect.sh`)
-- Multi-modem detection (`multi_modem.sh`)
-- Signal monitoring (`signal_monitor.sh`)
-- Auto IP recovery (`auto_reconnect.sh`)
+- Hotplug support for auto-detection
+- Firmware updates for modems
+- Network optimization based on signal
+- LuCI-ready JSON output
+- Full WWAN automation
 ## Installation
-1. Clone repo: `git clone git@github.com:Doanduy09/5G-Modem-Support.git`
-2. Copy scripts: `scp scripts/* root@192.168.1.1:/usr/bin/`
-3. Install kmods: `opkg install kmod-usb-serial kmod-qmi-wwan kmod-cdc-mbim kmod-sierra kmod-cdc-ether`
+1. Clone: `git clone git@github.com:Doanduy09/5G-Modem-Support.git`
+2. Copy: `scp scripts/* root@192.168.1.1:/usr/bin/`
+3. Hotplug: `scp scripts/wwan_hotplug.sh root@192.168.1.1:/etc/hotplug.d/usb/20-wwan`
+4. Install deps: `opkg install atinout qmi-utils libmbim ip-full`
 ## Usage
-- Detect modems: `sh /usr/bin/main.sh detect`
-- Check logs: `cat /var/log/wwan_kmod.log`
-- Full usage: `sh /usr/bin/main.sh {detect|lock <bands>|diag|connect <protocol>|auto}`
+- Run: `sh /usr/bin/main.sh {detect|install|lock <bands>|diag|connect|auto|update <firmware>|optimize|luci}`
+- Example: `sh /usr/bin/main.sh optimize`
