ipad wifi issues

[Issy7862008]

Hi,
The maximum download speed I get from my iPad mini retina is almost half that of my iPhone and macbook. My ISP gives me 60mbps internet, however i only get around 30-40 on my macbook air and iPhone 5c and this tends to fluctuate to lows of 10. But on my iPad I only get around 10-15 average this can go up to 40 but rarely does.
I know my wi-fi router is the bottleneck as always get 60mbps download when on ethernet. It is a stock CBN cable modem router literally in the same room as where i use my iPad, and I also live in a building with 15 other routers from the same ISP running on 2.4ghz. Could it be interference or compatibility issue with the router and the iPad?

All software has been updated.

Any help would be thoroughly appreciated

What protocol is the router set for?

Not sure what protocol exactly is, but it states that it has NAPT mode enabled if that's any help

Thanks

802.11B, 802.11G, 802.11N, etc. sometimes only shown as letters (B,G,N) or a combination of these?

I have checked and it seems to be in mixed transmission mode currently using 802.11b,g and n

N is faster than G and G is faster than B. You shouldn't run B unless you have to. B is usually used by really old devices and is really slow. Everything I use is capable of N so I run N only.
