How to connect Internet in R.C.P.R. Reality – Cejl 71, Brno

1. In each room there is one available RJ45 „live“ conection.
Very often it is a left side RJ45 conector in wall socket.

2. How to connect one notebook?

First time try to use UTP network cable to connect between socket and your ethernet network card in notebook. Please check if LED status indicators on the notebook lights with orange/green color. If not, something is wrong or your notebook does not have LED indicators at ethernet port.
If it works you have to setup IP address to obtain from DHCP server. In this case you should obtain IP address like 10.20.101.x. If not, something is wrong.

3. How to connect more computers?

Very simple way is to use ethernet switch. You can connect any port of ethernet switch into „live“ wall socket. Simle to check status of port at switch on the LED panel.

4. How to create simple wifi network on my notebook (Windows7/8/8.1/10)?

If you need to create a little wifi network for your mobile phone etc. you can use your Windows as hotspot for your mobile phone by running next commands in command line.

First connect notebook to the wall socket using UTP cable and check taht Internet is available. To start wifi run those commands in command line. You have to run cmd.exe as Administrator! ! ! For example next run commands :
C:\> netsh wlan set hostednetwork mode=allow ssid=MYROOMXXX key=12345678
C:\> netsh wlan start hostednetwork
Now you can see wifi MYROOMXXX and connect to this wifi on your mobile phone etc.

To stop wifi hotspot run command :
C:\> netsh wlan stop hostednetwork

5. How to connect via your own router or wifi AP/router hardware?

Unfortunatelly the R.C.P.R. does not provide wifi network on all places.
We understand that you can need to connect more than one notebook or use your own wifi connection at room (cell/mobile phone, tablets, phablets, etc.). For this purposes you can buy your own AP/router and connect to the network LAN. You can connect router/AP in one of two modes.

* Connect in router mode (prefered)
Connect router from WAN/Internet side using UTP cable to the „live“ wall socket RJ45 connector. Check LED status indicator for the WAN/Internet port; they should blink or light.
In router maintanance you should see that WAN side obtain IPv4 address like 10.20.101.x.
Next you can connect your computers to the LAN side of router or configure your own wifi Access Point and connect using wifi.
All computers are hide behind your router (NAT, firewall) and are not avilable to connect from the other neighbours computers in R.C.P.R.

* Connect in bridge mode
In this mode the router works just only as as switch. The computers are obtaining IP addresses not from router but from central router in R.C.P.R. You can do it by simple connect router into wall socket from the LAN side. But be sure that you disable DHCP Server function on your router!!! If you do not understand what do to please use „connect as router“ method. If you connectyour router with DHCP Service in LAN your socket wall will be disabled and you will have no internet connection.

The other settings of your router, LAN IP addresses, wifi AP name and security, is on you.

6. What to do in any problems?

First try simplest connection the notebook with ethernet network card direct into wall socket.
Choose correct RJ45 connector . Check if LED status indicators in the notebook network card blinks.
Check what IPv4 address you got. You command „ipconfig /all“ in Windows or simmilar to view IP configuration. Please send the output into file to send it via email or print it.
Check availability of your next hop using command „ping 10.20.100.1“.
Check availability of DNS and Internet using command „ping 8.8.8.8“ or „ping www.google.com“. Store the output as text files to be able to show it later or send it via email.
