1. My desktop doesn't have wifi.
If it has a spare USB socket, purchase a USB-to-WiFi adapter.
2. I prefer the stronger connection of Wifi.
A "CAT-5E" (or "CAT-6") Ethernet cable will give you whatever download speed that you are paying Shaw to get.
From a web-site:
Below is a breakdown of the various 802.11 WiFi standards and their corresponding maximum speeds.
Theoretical wireless speeds (combined upstream and downstream) are as follows:
802.11b - 11 Mbps (2.4GHz)
802.11a - 54 Mbps (5 GHz)
802.11g - 54 Mbps (2.4GHz)
802.11n - 600 Mbps (2.4GHz and 5 GHz) - 150Mbps typical for network adapters, 300Mbps, 450Mbps, and 600Mbps speeds when bonding channels with some routers
802.11ac - 1300+Mbps (5 GHz) - newer standard that uses wider channels, QAM and spatial streams for higher throughput
So, your download speed depends on whether your WiFi adapter has "a" or "b" or "g" or "n" or "ac" capability.
3. I'm assuming that the Blue Curve TV player needs it, otherwise why did it come with a ethernet cord (And connection).
No useful comment.
4. ... my work computer isn't allowed to be connected to a wireless connection in any way.
What non-technical manager made that silly suggestion? It makes no sense.
Any wireless connection between a computer and a WiFi router is encrypted.
Any Ethernet connection between a computer a "wired" router is NOT encrypted.
Is that computer still located at your previous office, or did you bring it home with you?
5. The last is my xbox. And I don't have the wireless adapter for that.
Purchase one from Amazon or BestBuy or Staples or London Drugs or a local owner/operator computer store.
Bottom line: as @rickatk wrote, a "hub" or a "switch" is all you need, to add more Ethernet ports.
