I was reading through the threads a while a ago, I read somewher that basically, If at least 1 device does not support AC, then the router has to put the setting to something lower than AC? And im assuming that this will greatly affect everyone else that is connected to the router?

there is normally a setting for both AC and non-AC at the same time. no need to disable AC completely. this way everyone gets whatever speed they can through their device. my house has devices of N and AC rating. everyone gets the speed their device is capable of.

keep in mind though that if one user is taking all the bandwidth then everyone else will suffer for it. you can only total the speed you pay for house-wide no matter what speed devices are capable of.

Yes, say if you are using the 5Ghz band and you have 5 AC devices connecting, but than you have someone connect with a device only capable of N, this will affect everyone else s capable speeds due to how WiFi works, this is a reason why many wifi routers or AP's have options to limit or remove support for older technology like A,G,B

Is the above mentioned Setting available for most routers out in the market?

i've not seen one yet that did not have it. can't speak for 100% of the routers out there but i'm pretty sure it's a standard ability. when N rating came out, those routers also had the option to use b/g, n, or all of them as well. so it's not exactly a new option.

I know this was a problem with 802.11 b/g, and to a lesser extent n. If a b device connected to a b/g router, it would force the router into b mode, causing all g devices to fall back to b. In addition, the speed of b/g was locked at the speed of the slowest-connected device. So having an old b device in the far corner of your house always connected could force your WiFi network to 802.11b 1 Mbps even though the router was capable of 54 Mbps 802.11g.

802.11n on 2.4 GHz was a little better since it operated independently of b/g (n devices couldn't be forced to fall back to b/g). But there was still some performance loss due to the router having to switch between n and b/g modes.

I believe the situation was improved with 5 GHz 802.11 n/ac (ac is 5-GHz only, while n works on both 2.4 GHz or 5 GHz). That n and ac were designed so the router can switch between the two seamlessly. Both use encoding which scales bandwidth based on the amount of noise. So you can assign both to the same frequency slots. If at any given time only an n or ac device is transmitting, it sees no noise so gets the full bandwidth. If both are transmitting, they see each others' broadcasts as noise which ends up divvying up the bandwidth between them automatically. I will admit though that I hadn't really followed the development of n/ac closely (I basically skipped 5 GHz until after ac was out), so this is a bit of conjecture on my part.
