Do I understand router bandwidth?

[Chris]

I just wanted to check with the brilliant people of the internet and see if I understand bandwidth from my router correctly.

We used to have a desktop PC that was hardwired, so I paid for the 50mbps connection. That PC is gone now, and we are only using the WiFi, which I understand is limited by the router to 20mbps. So basically, I have no reason to continue paying for 50mbps if I'm never hardwired and only using WiFi, correct? I wouldn't notice a performance drop because we aren't able to take advantage of the full 50mbps speeds through the WiFi anyway, correct?
Peter H: It would appear to be 802.11n compatible, and the Netgear website says that this model should have WiFi speeds up to 152mbps. Mine is a few years old, so probably not EXACTLY like the one on their site: http://www.netgear.com/service-providers...-techspecs

I have never seen anything in excess of 17mbps from my WiFi, and the geniuses at Comcast have told me multiple conflicting things in regard to this question, so I consider them worthless as a source of good information.

It depends on how old your router is. A modern one, with WiFi to the IEEE 802.11n standard, as opposed to the 11b or 11g standards, will have a bandwidth of at least 54 Mbps.

You need a new router then. Wifi is pretty damn close to the speed of a wired connection.
