So this is how my home network is setup. I have a PTCL ZXDSL modem router and connected to it is an old D-Link DIR-615 wireless router. Connected to my ZXDSL modem router is my desktop PC. My laptop I use wirelessly but sometimes I connect it via ethernet cable to the ZXDSL modem router so as to get a more stable connection. The problem is that the ZXDSL and the D-link are both 10/100 which makes it a nightmare to transfer large files over the network. I intend to use the laptop for torrents but all the excess storage place is in my desktop, so i'll be transfering files regularly. I need to shift to 100/1000 gigabit. Both my laptop and my desktop are 100/1000 gigabit. I don't mind having to connect a lan cable to my laptop whenever I need to transfer files. What would be an economical way to go about this
