It is necessary to distribute Wi-fi in a room where there is Ethernet (see diagram). What is the best way to do this?

Question

WiFi

Hello!
There are two rooms:
You need to distribute Wi-Fi in Room 1.
What is the best way to do this?
So far I have considered two methods and both have questions.
Method 1. Embed a Wi-Fi adapter in your PC and configure it for distribution through a special program, for example, Connectify.
Questions:
1. Any Wi-Fi adapter can be configured to distribute?
2. Which is better, external USB or internal, for example, PCI?
3. I have Windows 7, which program is better to use?
4. What are the pros / cons of this method?
Method 2: Purchase a Wi-Fi Switch
Questions:
1. How to configure the network in this case?
2. Is it worth it if there is only one PC in the room that needs an ethernet connection?
3. What are the pros / cons of this method?
What other ways are there?
Please advise how best to proceed.

Answer 1

I still don't know how to set it up correctly.

set up the master router (enter data for connecting to the Internet, set up wifi, save the settings, restart the router and make sure that there is Internet access).
disconnect from the master router.
connect by wire to the slave router.
on the slave router, set a subnet different from the subnet of the master router.
for example: host 192.168.2.1 ; 2 is the subnet address. on the slave set any other - 192.168.3.1.
configure the wifi settings on the slave router.
save the settings on the slave router.
turn off the dhcp server on the slave router.
save the settings on the slave router.
connect the lan ports on the slave and master router with a wire.
now the slave router works as an access point + switch, it does not deal with routing.
to get into the settings of the slave router, manually set the network card of the computer (network and sharing center-view active networks-ethernet-properties-ip version 4) ip address from the subnet of the slave router, for example: router - 192.168.3.1; computer network card - 192.168.3.2; the subnet mask is 255.255.255.0. gateway address - leave blank or enter the slave router address.
after manually entering ip, Internet access will be lost, and will return only after switching to automatic address acquisition.
you need support for ad-hoc networking
, an external antenna is also desirable, otherwise the stability of the wifi connection will be low.
adapter or router - it's up to you,
if you're not in a hurry - buy mysku.ru/blog/aliexpress/29103.html or similar.
or even run a second ethernet wire from the router and buy the cheapest access point you can find, you can even take a used one.
