How does Huawei HG80 10 Optical Cat use ZTE H608B sent by Telecom to open routing and WIFI?

You two cats can't be connected as routers.

Only 1 fiber-one as a switch, of course, H608B has no routing and wireless functions. Computers naturally need to dial.

Solution:

Use optical cat+wireless router (purchase)

Find Tietong to replace it with an optical cat with wireless (it is best to have permission to set the route to turn on the wireless, otherwise it will be cracked).

Finally, I want to say that if the second cat can brush other firmware to turn the LAN 1 port into a WAN port, it can directly solve your problem without buying or changing cats.
