If the SIM card is inserted properly and the internet connection is normal, you can continue the
setup in Step 4.
If No SIM Card is shown on the page, refer to No SIM card detected.
If SIM card blocked is shown on the page, refer to Unlock the SIM card in the quick setup wizard.
Step 4 Set parameters as required, and click Next.
If you do not want to use a password, tick No Password. In this case, any client can access the
network without a password. No Password is not recommended as it leads to low network security.
To use the same password for Wi-Fi access and web UI login, tick Sync the login password with
the Wi-Fi password.
To use different passwords for Wi-Fi access and web UI login, set Wi-Fi name and Wi-Fi password
for Wi-Fi login and login password for web UI login.

To access the page, log in to the web UI of the router, and navigate to Advanced Settings > Firewall.
Parameter description
Parameter
Description
ICMP Flood Attack Defense
Used to enable or disable the ICMP flood attack defense. The ICMP flood attack means that, to implement attacks on the target host, the
attacker sends a large number of ICMP Echo messages to the target host, which causes the target host to spend a lot of time and resources on processing ICMP Echo messages, but cannot process normal requests or responses.
TCP Flood Attack Defense
Used to enable or disable the TCP flood attack defense. The TCP flood attack means that, to implement attacks on the target host, the
attacker quickly initiates a large number of TCP connection requests in a short period of time, and then suspends in a semi-connected state, thereby occupying a large amount of server resources until the server denies any services.
UDP Flood Attack Defense
Used to enable or disable the UDP flood attack defense. The UDP flood attack is implemented in a similar way with ICMP flood attack, during
which the attacker sends many UDP packets to the target host, causing the target host to be busy processing these UDP packets, but unable to process normal packet requests or responses.
