There is no wireless wifi in the hotel. Can I use it with my wireless router?

Yes, but please note that the routing settings should be modified as follows:

1. Turn off the DHCP of the route first, and change the IP segment 3 of the local area network to non-0, non-1, such as 5, to avoid IP conflicts with other hotel guests.

2. Cabling into the routing LAN port (non-WAN)

This is better than AP mode, and the mobile phone can surf the Internet wirelessly.

If you travel frequently, it is recommended to buy a mini wireless route at around 100, with preset AP mode, plug and play, to avoid walking on both sides of the hotel and being switched.
