wonderflonium164 :
Thank you both for you responses. To clear up some questions allow me to repeat myself: 1. 10+ devices over wifi, 5 over wired ethernet. 4 PC's (only two capable of gaming) and a Dish Hopper. 2. LAN to LAN connection is 12 mBIT, or 1.5mByte.
According to your remarks and details provided I am going to assume firstly using CenturyLink ISP.
Though unknown to me, I did check up this web page for "compatible" hardware to be used;
http://www.approvedmodems.com/centurylink.html ,is a page to look at, now you can also ask your ISP if they have a web page of their own (most do) or a list of client purchasable hardware (so you don't rent it from them) they recommend to use on their network.
if you want the "household internal network flexibility" then buy/rent the VS2 Modem only (no router inside it) and to manage your various devices, get a router separately (such's as ASUS, Netgear or other).see below for more on this.
Now that said, ADLS2, ADSL, VDSL2 and DSL have physical limits of speeds (maximum speed over copper wire of the telephone wire) when accessing the internet (even with best setup for internal network (streaming a movie from a NAS to a TV or device for example) the limiting factor when accessing the internet is primarily your ADSL speed (and max speed run about; "up to 25Megabits", which means it will usually be slower because of concurrent multiple connections accessing the internet at the same time (more phones device go on the internet slower each will be, this is not a router issue its an adsl/vdsl/dsl issue.)
My suggestion for such a situation is get a modem that will permit the smallest bottleneck with ISP, and use a good quality router that you can upgrade if you need to , but let me remind you that you will do management of the "devices" internally to optimize the network, too many people believe plug in and tada.. it will provide a miracle. no it wont.
<DISCLAIMER>
you will need to do you own verification, with your ISP and with your area provider to ensure the following hardware is allowed/supported with all proper functionality to your ISP, I make no warranties these are supported, as I have not spoken to your ISP , that will have to be your job.
I suggest according to what I see, the following combination;
TP-LINK TD-8616 DSL Modem (this connects your ADSL to your Wan port of your router)
http://www.approvedmodems.com/tp-link-td-8616-dsl-modem.html
then modem then connects to the wan port of the following router possibilities
before deciding on a router, you have to see what your devices can use in bands, 802.11ac, 802.11n etc. also 2.4ghz or/and 5ghz or MiMo, latest phones can use either 2.4 or 5ghz bands, and usability will depend on where how far they are from the router in the house. (multiple floors house? what's the square footage) will and can affect speeds and connectivity for each devices.
I like this router as it is solid, 2.4hgz and dual 5ghz bands, all bands can be setup as separate accessed by separated password, include visitor secluded from your network bands (give Wi-Fi to buddies but not access to your network just internet)
TP-Link Archer C3200 <
web link to neweggs.com website were all details can be found.>
you can go with a cheaper, lower abilities router (looking at the link above you have a comparison chart you can use) but with 12+ devices, I cannot suggest single processor dual bands router.
