is there a device which converts the incoming lan signals into wifi signals?
The apartment only has a fixed network ip with a predetermined gateway and DNS. One needs to give this static ip, netmask and gateway in the network configuration of the computer and it works.
But I would like to use smart phones to access the network. Hence the static settings should be done in the device ( maybe it is is called an lan to wifi adaptor ) itself . Ofcourse, I do not want an expensive ADSL or DSL because I do not need the modem functionality.
Also, it would be great to know how this network device works i.e how does it give the IP addresses to the connected devices - may be using NAT?
Help with links what I should look for, would be appreciated.
Edit 05 June, 2017:
I have a FritzBox 7240, which according to this manual ( German ) https://avm.de/service/fritzbox/fritzbox-7240/wissensdatenbank/publication/show/106_FRITZ-Box-fuer-Betrieb-mit-anderem-Router-einrichten/, should be able to fulfill my needs. But the problem there is, that the static IP provided by the external router is class B ( 134.x.x.x ). If I enter this static IP into the FritzBox's Routers configuration and activate the DHCP server of the Fritzbox to provide IPs ( Class C - 192.168.178.x ) that would distribute the IP's to the connected devices, the Fritz box complains a conflict between the Class B incoming IP and the class C Fritzbox's DHCP IP.
So, I have left with no other choice, but to buy some other device like an Access Point.
