Yea im getting 100-120 Mbps when i use my computer speed test but when I use the PS3 speed test I only get 35 Mbps i think its max is 35 or 40 Mbps... and yes there is 100 Mbps internet look at charter.com or comcast.com
As Plymco_Pilgrim said, your speed is limited by the hardware in the PS3. I like to add, as well as, other factors.
To have the best network experience with the PS3 use a wired connection. For its wireless interface the PS3 support 802.11g & b. Wireless G provides a max of 54Mbps speeds where wireless b is slower. The wired interface is a Gigabit Ethernet port, do make use of it.
lol 100mbps isn't that big of a deal, its 2013. I understand a lot of the world doesn't run on Fiber Optic internet yet, but its been getting more common since about 2009.
I run on about 150mbps Fiber Optic through a company called Surewest, which is only available in 2 towns in the US- Sacramento and Kansas City lol. But there are others out there. I'm only paying about $125 and that includes a DVR, and TV in 5 rooms and home phone service.
