RJ45 Wireless Dongle?

[Nigel Molesworth]

There are plenty of devices that will enable a PC to connect to a wireless
network AP via a USB plug, a PCMCIA card, or a built-in card.

Can one get a device that connects via an RJ45?

Hi
Many Access Point and some Routers can be configured to work in Client Mode
(Aka Group Bridge).
When configured this way the device can be plugged with Cat5e cable to a
computer's Ethernet card and serves as a Wireless card.
Most game box adapter are Wireless Client via RJ-45 too, but they tend to be
expensive.
