there's a box on the top left that compares your result to others....18mbps is pretty good mines about the same, a mates is 50mbps! but he's paying 50 eur a month and downloads movies like crazy. what you've got is more than enough for downloading movies and good streaming.
well mines half speed of your result so must be good ay!!,all depends who your provider is an what you pays,also if your in a naff area,or whilst the worlds on line with your provider!!!!!!!!!!! feckin endless excuses ,as long as its working nowt to worry bowt
That's still a very respectable speed though.....and still enough to watch streaming video on Beeb iPlayer etc with no problem
Check the specs of the wifi kit you have....it will (obviously) only run at the speed of the slowest component, which causes a bottleneck- it may be that you have a bit of kit that's only able to send/recieve at 10mbs anyway.
If you feel the need for more speed, try raising the router that sends the wifi signal higher in the house to get a better all round signal....there are also lots of other ways of boosting the speed but TBH, as above, that's a very very usable speed so it may not be worthwhile.
I'd be quite happy if I achieved that speed on my wired connection coming into the flat in the first place, let alone on the wifi signal!
