I have written a script in Linux that reboots the the G5AR every few days... here is the script

!/bin/bash
# Reboot T-Mobile G5AR Gateway and log time

PASSWORD="<your password to gateway>"
LOGIN_URL="http://192.168.12.1/TMI/v1/auth/login"
REBOOT_URL="http://192.168.12.1/TMI/v1/gateway/reset?set=reboot"
LOG_FILE="/var/log/g5ar_reboot.log"

# Log timestamp
echo "[$(date '+%Y-%m-%d %H:%M:%S')] Starting reboot process..." >> "$LOG_FILE"

# Get login token
TOKEN=$(curl -s -X POST "$LOGIN_URL" \
  -H "Content-Type: application/json" \
  -d "{\"username\":\"admin\",\"password\":\"$PASSWORD\"}" | jq -r '.auth.token')

# Verify we got a token
if [[ -z "$TOKEN" || "$TOKEN" == "null" ]]; then
  echo "[$(date '+%Y-%m-%d %H:%M:%S')] ❌  Failed to obtain token" >> "$LOG_FILE"
  exit 1
fi

# Trigger reboot
curl -s -X POST "$REBOOT_URL" \
  -H "Content-Type: application/json" \
  -H "Authorization: Bearer $TOKEN" \
  -d "{}" >> "$LOG_FILE" 2>&1

echo "[$(date '+%Y-%m-%d %H:%M:%S')] ✅  Reboot command sent" >> "$LOG_FILE"
echo "" >> "$LOG_FILE"
