Wired > wifi. Wifi is too slow for my connection and the latency is at least 20ms higher than on wired connection. I would not play any online game on wifi.

If you are getting an extra 20ms of latency, you need to work on your Wi-Fi set up.

Try pinging your router.
Here's mine and I run 802.11 G.  
3ms

21ms more latency and 150mbps less dl speed.

21 ms latency?  You have a problem with your set up.

And your download speed problem is irrelevant.   Not only do the overwhelming majroity of people have a download speed far, far slower than their Ethernet ports transfer speed but latency is by far the bigger factor in online gmaing.   You won't find an actual differnce in the online experience from an 8 Mb connect  with low latency and a 500 Mb with low latency.

Because it is 2012 now. I have 350mbps connection now and pretty soon there is an option for faster connections here.

Absolute waste of bandwidth.  That's a fantastic download speed for just that, downloads.   For online gameplay, it's  50 times more than actually needed to sustain a solid connection.

Editing your post was interesting...

I get 1ms almost all the time with pinging my router from the same room, 1-3ms from next room and 1-54(lol) from third room. That has been the case always, but when I play a game online, my ping is 20ms higher than on my wired connection. That is with my laptop on the same room and playing on the same server with ethernet connection.

It isn't just about online gaming, it is also about downloading games from internet and in few years maybe streaming 4k movies. How much bandwith would a decent quality 4k stream take?

Funny, I don't feel that my bandwith is going to waste but if you say so...
