Is there a huge difference in speed and connectivity for 10 mhz and 20 mhz or even 40 mhz?
All things begin equal, a channel that is twice as wide, will give about twice the speed and capacity. Not quite, but in theory it can be twice as fast.
Of course, if using a larger channel bumps you into more interference, and if a narrower channel fits you into a small clean spot between other interferrers, then in that situation, a narrower channel can in potentially provide more performance - so with Wireless, you have to test it in your environment, since every situation can vary. : )

Each time you halve the bandwidth you halve the potential throughput. 10Mhz max theoretical is a bit more than 50Mbps, 20Mbps 100Mbps and change 40 is twice that (though less likely to be achieved thanks to noise more often than not).

Hi,
Throughput provided by the channels is almost totally proportial to the channel Bndwidth.
40 MHz ~ 200 Mbps
20 MHz ~ 100 Mbps
10 MHz ~ 50 Mbps
5 MHz ~ 25 Mbps
Please note channels with smaller Bandwidth are more stable in noisy environment because of higher spectral density.
Thank you.
