communicates across the Internet with another, the data packets travel through 
many  devices  along  the  way.  If  a  device  in  the  data  path  has  a  smaller  MTU 
value  than  the  other  devices,  the  data  packets  have  to  be  "fragmented"  to 
accommodate the device with the smallest MTU value.  
The best MTU value is often just the factory default value. In some situations, 
changing the MTU value fixes one problem but causes another. Leave the MTU 
unchanged unless one of these situations occurs: 
A. You  have  problems  connecting  to  your  ISP  or  other  Internet  service,  and 
either  your  ISP  or  our  technical  support  suggests  changing  the  MTU  value. 
Below Web-based applications might require an MTU change: 
 A  secure  Website  that  does  not  open,  or  displays  only  part  of  a  Web

page 
 Yahoo email 
 MSN portal 
B. You use VPN and encounter serious performance problems.  
C. You used a program to optimize MTU for performance reasons, and now you 
have connectivity or performance problems. 
If you suspect an MTU problem, try changing the MTU to 1400. If this does not 
help,  gradually  reduce  the  MTU  from  the  maximum  value  of  1500  until  the 
problem disappears. 
The common MTU sizes and applications are listed in the table below. 
MTU 
Application 
1500 
Typical for connections that do not use PPPoE or VPN.  
1492 
Used in PPPoE environments. 
1472 
Maximum  size  to  use  for  pinging.  (Larger  packets  are 
fragmented.) 
1468 
Used in some DHCP environments. 
1436 
Used in PPTP environments or with VPN. 
Note 
A wrong/improper MTU value may cause Internet communication problems. For 
example,  you  may  be  unable  to  access  certain  Websites,  frames  within 
Websites, secure login pages, FTP or POP servers. 
2.3 WAN Speed (Available only in Wireless Router Mode) 
Click Basic  ->  WAN  Speed  to  enter  the  configuration  interface.  Here  you can 
configure the WAN speed and duplex mode. 

33 
III Features & Configurations | Tenda 
Tip 
① The device operates in Auto (Auto-negotiation) mode by default. Usually, it 
works for most cases. 
② In some situations,  you might need to change  the speed/duplex mode. For 
example,  if  the  cable  connected  to  your  device's  WAN  port  is  longer  than 
100m,  you  may  need  to  use  10M  full-duplex  or  10M  half-duplex  for  better 
performance.  Ensure  that  your  device's  WAN  port  operates  with  the  same 
speed and duplex mode as the remote link partner. Otherwise, your device's 
WAN port may not receive and send data. 
2.4 DNS Settings 
Click Basic -> DNS Settings to enter the configuration interface. 

34 
III Features & Configurations | Tenda 
Configuration Procedures: 
① DNS Settings: Check/uncheck to enable/disable the DNS settings. 
② Primary  DNS  Address:  Enter  the  IP  address  of  the  primary  DNS  server 
provided by your ISP. 
③ Secondary DNS Address: If a secondary DNS server address is available, 
enter it here. This field is optional. 
④ Click Save to save your settings. 
Note 
The  default  DNS  settings  are  recommended.  Only  change  the  DNS  default 
settings  if  you  know  that  your  ISP  requires  specific  servers.  If  incorrect  DNS 
settings are configured, Webpages may not open. 
2.5 MAC Clone (Available only in Wireless Router Mode) 
Some  ISPs  (Internet  Service  Providers)  require  end-user's  MAC  address  to 
access their network. This feature copies your current PC's MAC address to the 
device.   
Click Basic -> MAC Clone to enter the configuration screen.

Restore Default MAC: Reset the device’s WAN MAC address to factory default. 
Clone MAC: Clicking this button copies the MAC address of the computer that 
you  are  currently  using  to  the  router.  Note  that you  have  to  use  the  computer 
whose  MAC address is allowed  by your  ISP.  Also, you  can  manually  enter  the 
MAC address that you want to use.   
To restore default MAC address: 
① Click Restore Default MAC. 
② Click Save to save your settings. 
To copy the MAC address of the computer that you are  currently using to 
the device: 
① Click Clone MAC. 
② Click Save to save your settings. 
To manually enter the MAC address allowed by your ISP: 
① Enter the MAC address allowed by your ISP.

2.6 DHCP Server 
DHCP  (Dynamic  Host  Configuration  Protocol)  assigns  an  IP  addr ess  to  each 
device  on  the  LAN/private  network.  When  you  enable  the  DHCP  Server,  the 
DHCP  Server  will  automatically  allocate  an  unused  IP  address  from  the  IP 
address  pool  specified  in  this  screen  to  the  requesting  device  as  long  as  the 
device is set to "Obtain an IP Address Automatically". If you disable this feature, 
you have to manually configure the TCP/IP settings for all PCs on your LAN to 
access the Internet. 
Click Basic -> DHCP Server to enter  the  screen below. Here you can change 
the DHCP IP address pool and lease time. 
Configuration Procedures: 
① DHCP  Server  -  Enable:  Check/uncheck  the  box  to  enable  or  disable  the 
DHCP server feature. 
② Start IP/End IP: You can specify the starting and ending addresses of the IP 
address pool here. These addresses should be part of the same IP address 
subnet as the device’s LAN IP address. 

37 
III Features & Configurations | Tenda 
③ Lease Time: The lease time is a time length that the IP address is assigned 
to each device before it is refreshed. 
④ Click Save to save your settings. 
Tip 
① By default, the device functions as a DHCP server. Do not disable the DHCP 
server feature unless you want to manually configure the TCP/IP settings for 
all the PCs on your LAN. 
② Lease time will be renewed automatically upon expiry. 
③ If  you  are  not  an  advanced  user,  the  default  DHCP  server  settings  are 
recommended. 
2.7 DHCP Client List 
Click Basic -> DHCP Client List. Here you can see a list of the DHCP dynamic 
clients  (if  any).  By  viewing  this  list,  you  can  know  whether  there  are 
unauthorized accesses. 
Also, you can specify a reserved IP address for a PC on your LAN. That PC will 
always  receive  the  same  IP  address  each  time  when  it  accesses  the  DHCP 

38 
III Features & Configurations | Tenda 
server.  Reserved  IP  addresses  could  be  assigned  to  servers  that  require 
permanent IP settings. 
Static Assignment Application Example: 
To  have  a  PC  at  the  MAC  address  of  44:37:E6:4F:37:38  always  receive  the 
same IP address of 192.168.0.123. 
Configuration Procedures: 
① Enter  the  last  number  of  the  IP  address  you  want  to  reserve . Here  in  this 
example, enter 123. 
② Enter the MAC address of 44:37:E6:4F:37:38. 
③ Click Add. 
④ Click Save to save your settings. 
Tip 
① If the IP address you have reserved for your PC is currently used by another 
client, then you will not be able to obtain a new IP address from the device's 
DHCP server, instead, you must manually specify a different IP address for 
your PC to access the Internet. 
② For PCs that have already obtained IP addresses, you may need to perform

the Repair action to activate the configured static IP addresses.
