LAN DHCP config

Configuring a custom IP address for the LAN makes it resilient to IP conflicts from other LAN network's.


  • Go to Network > LAN settings and do the following settings.
  • IPv4 Address:  192.168.50.1
  • Subnet mask: 255.255.255.0
  • DHCP Start IP address:  192..168.50.2
  • DHCP End IP address:  192..168.50.254

Note: After this setting the IP address of the Nokia router will be 192.168.50.1

LAN DNS config


Using adgurad DNS block the ads that are dependent on DNS server to resolve ads websites. this speed up the overall internet experience for users.


  • Go to Network > LAN settings and do the following settings.
  • Primary DNS: 94.140.14.14
  • Secondary DNS:   94.140.15.15


Wireless (2.4 GHz) Config

Doing custom setting in WiFi 2.4GHz network parameters can help in enhancing the performance of wireless network.

Mode:  Setting Mode to 802.11n standard, disables the support for old  802.11b and g standard. The newer standard is faster and stable.

Bandwidth : Setting the bandwidth to 20 MHz makes it resilient to interference compared to 40 Mhz. Some devices may not support 40 MHz bandwidth and may have difficulty connecting the wireless network. 

Channel: Setting it to Auto makes the router choose a good channel for the wireless network.

WPA version: Using a newer WPA2 standard makes the network throughput faster compared to WPA. Set this encryption mode for every SSID.

WPA Encryption Mode:  Using the newer AES encryption mode provides more security to the data traffic in the wireless network. Set this encryption mode for every SSID.


  • Go to Network > Wireless(2.4 GHz) settings and do the following settings.
  • Mode: n
  • Bandwidth: 20 MHz
  • Channel: Auto
SSID Configuration
  • Encryption Mode :  WPA/WPA2 Personal
  • WPA Version: WPA2
  • WPA Encryption Mode:  AES


Wireless (5 GHz) Config


Bandwidth: The router supports three bandwidths ( 20, 40 and 80 MHz). Choose one that is supported by every device connecting to the wireless network in 5GHz band. Choose 80 MHz band first.

Channel: 

Encryption Mode:  Using the newer WPA2-AES encryption mode provides more security to the data traffic in the wireless network. Set this encryption mode for every SSID.

  • Go to Network > Wireless(5 GHz) settings and do the following settings.
  • Channel:  Auto
SSID Configuration
  • Encryption Mode :  WPA2-AES
