Trying to Eliminate Redundancy
My 9-yr-old daughter needs a better connection from her MacBook Pro to the router than wireless signal is allowing for. I would like to connect an ethernet cord to her MacBook's USB-C port. Apple recommends I plug a Thunderbolt 3 (USB-C) to Thunderbolt 2 Adapter ($49) into her MacBook. Then they recommend I plug a Thunderbolt Gigabit Ethernet Adapter ($29) into that. Then they recommend an ethernet cord from there to the modem.
I am not well-versed in this sort of thing, but this seems to me needlessly redundant and costly, especially when, in the old days, computer ports allowed for a cord from the router directly to the computer, with no "middlemen".
Is there such a thing as a CAT5 or CAT6 cord that has an 8P8C (RJ45) on one end, and a Thunderbolt 3 (USB-C) on the other? If not, are there quality devices that are direct Thunderbolt 3 (USB-C) to Ethernet, which I could then run a cord from to the router?
Thank you for any thoughts, or alternative ideas, you might offer. It is appreciated.
