Ethernet To Coax Adapters, Or Not?

There are a bunch of ethernet to coax adapters everywhere ranging from $10 all the way up to $100. Is one any better than the other? As of right now, I am using a wireless AT&T U-verse box to connect to my router and it is TERRIBLE. It has gotten to the point where CS:GO is completely unplayable due to ridiculous amounts of rubber-banding and an average ping of 170.

This is the first test I've done in a while that resulted with no packet loss. Even just pinging my router I usually get 10-15% packet loss.

What would be the better option here: Buying an ethernet to coax adapter because I have a coax cable that runs from my modem/router to my room, or buying a wireless card and connecting through 5-6 walls to my mediocre AT&T router/modem

Can you explain your setup a little more clearly?

Your cable comes into the house into a modem, then the modem sends it into another coax cable that then hooks into a coax to ethernet converter in your room? Or...?

That is how it used be be and that was fine. The line would come in to the AT&T box in my room and then ethernet from there to my desktop.

Now, they replaced my box with a wireless one, so I run ethernet from my desktop to my AT&T U-Verse box, which then wirelessly connects to the router.

I can't visualize that setup. Maybe it is a U-Verse thing. Given the fact that you're using a wireless connection, that is probably a lot of your problem. Have you looked into using a wireline connection to the router?

Why not use a crossover ethernet cable to the two boxes? I'm having a hard time figuring out what you are trying to do here.

If I understand this what you want to do is

Uverse box > HomePNA (ethernet over coax) > HomePNA adapter  > your computer

                                                      |-> HomePNA adapter > your other wifi router

And what you have going on right now is

Uverse box > ethernet > your computer

       | -> wifi > other wifi router (or wireless bridge)

                               | -> other wireless clients

and it's terrible.

Do I have this right?

I must have been really tired when I wrote this because it doesn't even make sense to me. What I want to know is:

1. Is any ethernet to coax adapter better than another? They seem to vary greatly in price and that led me to believe something was different between them.

2. Would it be better to use a hardwired connection with a coax cable, or use wireless via a wireless adapter

You got the part about what I currently have right, but let me try to explain what I want.

I have a coax cable that runs into my room directly from my modem, however I cannot use it because desktops don't use coax for internet. I was questioning whether it would be better to buy an ethernet to coax adapter (and if so which one) or buy a wireless card.

Well, that depends on the type of wireless. If you can use wireless N, and you don't need like, blazing fast gigabit LAN speeds (which you wont get over coax anyway) then wireless N is fine. Bear in mind though, with a USB wifi adapter, you are LIMITED to the speed of the USB bus (bet you cant guess how i know this). if you plug in a wifi adapter to an older, usb 1.0 port, no matter how good your router is you are limited to 12mbps speed (thats as fast as usb 1.0 is) so if you can its probably better to use PCI wifi card, they seem to be better and more reliable
