Not a question that can be answered as there are too many variables that can effect wireless speeds.
Providing there are no local causes of interference then you should be able to reach similar speeds to an ethernet connection.
No wireless connection is guaranteed though.
My wired speed is 77/18Mb, Wireless speed on my Ipad2, Tab10.1 and S2 phone are around the 36/20Mb range, Why it show's my up speed in test's as higher that my wired I have no idea, in fact sometimes it comes back as 24Mb on all 3 devices. hope this may be of help to you
Hi to give you some idea i'm on infinity 2 and the fiber cabinet is right outside my house. My wired speed is 76/16 almost 100% of the time. The wireless speed on my laptop is 45/16 at best but usually around 38-40 down and 13 up.
all i use is wireless on my laptop but as mentioned speeds do vary . i have a n adapter in my laptop so can get upto 144mbs connection speed my ip profile is 52 odd and normally get around 50 on the speedtester wirelessly but has been as low as 30 odd wirelessly. still beats 5 meg on normal broadband hehe !
I'm on Infinity 1 (40/10 max), actual speeds averaging 38/8. My wireless laptop achieves similar speeds to my ethernet connected desktop. In fact my more modern laptop feels faster than my creaky old (but dependable) desk top. I've only been an Infinity customer for a week, but so far so good.
