I'm sure this has been asked a million times but I cant find a definite answer. Some facts: I have a wireless router with 6 ports. Each port is connected. I send one connection to another router in a separate building and one is to a repeater. The others go to desktops and printer. Some of the cables are factory and some I have made. We have a slow connection, 1.4mb/.6mb due to remote location. Several items are connected wirelessly to the router. Phones, laptops, satellite tv, etc. All seems to work surprisingly well considering our internet speeds. I am wanting to replace the router with one that has dual usb ports so we can connect a cloud drive and a printer for wireless printing from tablets and phones. I will relocate the router from its existing location and need to reconfigure some of the cable routing. I will need to re-cable in a couple of walls so I will need to reconnect some connectors and sockets. I have checked and searched about pin outs for the rj45 and sockets. It seems that the 3 types of connections are the A & B and crossover pin outs. I have made several cables using a non conforming color code sequence. I have just followed the same color code for each end. I have not had any problems that I know of and don't seem to be losing speed or have connection problems. Now the question. Am I actually losing anything by not following the standard pin out? If I change the existing connectors to follow the standard will I gain anything?.
