Well i got a 300meg wireless n adaptor . Is there no way of getting that speed through wireless
The Sky SR101 and SR102 routers are not top spec for WiFi. If you want fast WiFi then you will need to buy something else that manages 3 streams (450Mbps) at 2.4 Ghz AND also 5 Ghz. Much of the reason WiFi is slow is due to interference in the air, especially at 2.4 Ghz.
Here in my flat, I get 50 Mbps on a wired speed test. On 2.4 Ghz I can usually only get 18 or 19 Mbps even opposite the router. At 5 Ghz, I can get 50 Mbps. I have a LOT of other people around with WiFi as you'd guess in a flat, and they're all on 2.4 Ghz only.
inSSIDer or similar tools can show the issue, but sadly inSSIDer is now a paid product for Windows users. On the Mac you can get WiFi Scanner in the Mac App Store (inSSIDer for Mac is useless). There is nothing for iPhone or iPad as Apple don't allow it. On Android devices there are a few free scanners that work well. Not all devices support 5Ghz.
