I live in a hotel apartment, rent a single room and use telecom broadband for one month, but I don't know why the following problems have appeared in recent days. Excuse me.

According to your description, you can have a look:

1, check whether the connection indicator light of the router is normal;

2. Plug the network cable into other ports of the router to eliminate the fault of one port itself;

3. Try changing a network card to eliminate the failure of the motherboard's own network card;

I hope it helps you.

If you need to purchase a mobile phone, you can go to Anhui Telecom Tianyi Store (/shop/) and have a low price 100 mobile phone.
