First of all, thank you for your answers.
Of course this scenario cannot be possible and make a network work based on it. So, as for the question, that means that no user can work fine in the internet with two routers installed in a network sharing the same ip address.
The problem is that I was called by a company that had the problem that I analyse in this scenario. The users of the network could see the internet for e.g. 3 minutes, then they could not see it for 4 minutes, then again they could see it for 5 minutes and so on.
The problem was caused by router b, that was a router-switch but was used only as a switch. It had the same ip with router a (192.168.1.1). The problem was that on both routers DHCP service was enabled. I would like to inform you that router a (router with ADSL cable on it) was on the rack on the third floor. In this rack was also the 24-port switch. Router b was in an office of the first floor. So, two pcs were connected on two ports of router b and from a third port of router b a cable connected it with the switch of third floor.
I decided to give router a the address 192.168.1.189. An address that was commited by no pc or other network device on the network.
I adjusted pcs to be given automatically IP ddresses and not any constant addresses and I let on both routers a and b DHCP service enabled.
Now, to be covered, I removed router b from the network and replaced it with an ONLY 4-port switch and everything is working fine.
But my huge query is:
All these problems and new settings on network terminals and routers, router b replacement e.t.c. was caused because the ADSL router that the company had at first was broken. Before it was broken, it had DHCP enabled and it was giving IP addresses to terminals as they were adjusted to be given automatically IP adresses. All these were happening with router b installed on the network with the same settings:DHCP enabled and working just as a switch. The IP of this first router was 192.168.1.2 and, as I said before, router b had always ip 192.168.1.1. So, here is my huge question:How is it possible, before this first router stopped working, everything work fine, and after its replacement to have the problems?
I inform you that, after the replacement of the first router with router a, and after giving router a the ip address 192.168.1.189, the problem on the network existed. That's why I replaced router b with an only switch.
Consequently, we have the following in the company:
condition A
first router ip:192.168.1.2 DHCP enabled
router b ip:192.168.1.1 DHCP enabled
both routers on the network
network status:internet working fine on terminals
condition B
first router stopped working
replaced with router a
router a ip:192.168.1.1 DHCP enabled
router b ip:192.168.1.1 DHCP enabled
both routers on the network
network status:internet problems on terminals
condition C
router a ip:from 192.168.1.1 changed to 192.168.1.189 with DHCP enabled
router b ip:192.168.1.1 DHCP enabled
both routers on the network
network status:internet problems on terminals
condition D
first router ip:192.168.1.189 DHCP enabled
router b replaced with an only switch
network status:internet working fine on terminals
How is it possible on condition C the network not working as it is the same with condition A?
Thank you.
