From what I can gather from your question, what you need is a wireless router with an Ethernet WAN/Internet port. Unless you had an ISP connection that offers an ADSL service, then you do not want a router with an integrated modem.

The TP-Link router you have identified should be suitable. You will need to unplug the Ethernet cable from your computer and plug it into the WAN port on the router. You can use another Ethernet cable to connect the computer to one of the LAN ports on the router.

You will have to log in as you do at present, but this should be from any single device. After this, any other devices connected to your router either by Ethernet or WiFi should work without needing to be logged in themselves.

You will have to check the sub-net that your computer currently gets from the LAN cable, and if this is the same as the sub-net that the router offers, then you will need to log on to the router and change the sub-net it is using.

I hope this helps.
