A9: You can reset the router and set the login password again. To reset the router, power on
the router, hold down the Reset button for about 8 seconds until all the LED indicators blink
once, and release it.
Q10: What should I do if the email function does not work properly and some websites are
inaccessible?
A10: This problem is mainly encountered by users who access the internet using dial-up
connections or dynamic IP addresses. You can adjust the MTU value of the router to address
the problem. For details, refer to MTU.
If you cannot access some websites or encrypted websites (such as online banking and Paypal
websites), cannot send or receive emails, or cannot access FTP or POP servers, try reducing
the value of MTU gradually from 1500 until the problem is resolved. (The recommended range
is 1400~1500.)
