have such components like capacitors or diodes that could hinder back 
high frequency signals. 

 Note:  When MT880 has been used for a long time, the surface of the 

shell will reach a certain temperature. Don’t worry, this is a natural 
phenomenon and the Router can still work normally. 

 

1.  Why does the ADSL Router fall off line so often? 
There are many factors concerned, such as faults in your ISP access server 
or ADSL Router (compatibility or quality problem), Ethernet card (low 
processing speed, invalid driver), line disconnection, line disturbance and etc. 
You are suggested to check the following items in your applicable range: 
(1)  Ensure the ADSL connector is valid; 
(2) Keep the device away from heat sources, power line or highly powered 

electronic equipments; 

(3) Ensure no telephone or fax machine is connected directly to the ADSL 

subscriber line; 

(4) Update the old ISA NIC with new driver or replace it with a new 10/100M 

PCI NIC;
