(I connected to the wireless router through the cat. It used to be fine. Recently, I have been disconnected from the network. There is no way to connect. If I turn it off occasionally, if my character is good, I can still connect. I can, I wonder what caused it. I use Tietong. Based on the phenomenon you mentioned, it may be that the router is not working. Especially now that the weather is hot, it is best to restart the router often, or replace a router. The general troubleshooting process is as follows: 1. Check whether the cat's signal light is flashing when the line is disconnected. If it is, then the line may have a problem with the cat; 2. If it is normal, then remove the router and dial directly. If it can be dialed up, That's a router problem.)
