I have 2 computers (1 with ethernet card and other has ethernet port built-in, so 1 port for each comp) around 30ft apart. and I have 2 routers, D-Link GLB502T and UTR300R2U (both have 1 USB and 1 Ethernet port)I have BSNL-500 NU connection.Now, I want to use net on both comp such that,1. I should be able to use net on either comp individually (with other comp switched-off)or2. Use it on both comps simultaneously.so, is it possible with the hardware I have at the moment? (including a cable of 30ft) or do I have to buy the ethernet-switch?
