Solution
1
DNS problem
Check the DNS server of H685 is correct. The
DNS is from the ISP once H685 is online.
Sometimes the ISP not give the right DNS
server IP, you can try to set correct DNS
manually at your PC or Device network card.
2.
SIM card business problem
Check APN parameter of WAN port, then make
it correct and try. Double confirm with the
ISP/Carrier if the sim card info is 100% correct.
Try to change another sim card to try.
3
Signal is too weak
Too weak signal may cause all the DNS
resolution fails. Try to get better signal.
4
Network is too bad
Contact ISP/Carrier to get better network
4.16 Port forwarding not working
Question: I configure the port forwarding feature correctly, but still no work.
Answer: first, please check the port if block by your ISP/Carrier, because some ISP/Carrier block some ports for
security reason.
For example, the H685m gets WAN IP 27.38.14.223. And the H685’s web port is 80. So from the other network,
try to visit http:// 27.38.14.223:80 if can be okay. If no okay, it means the ISP/Carrier blocks the 10000 port. Then
check with your ISP/Carrier which ports are open for use. Then re-try the port forwarding feature.
