IP Address issues? Only seems to be with WiFi.

Hi,

I've been having weird internet drop-outs and it's because of IP Addresses as far as I know.
Sometimes when I assign a static IP to a Phone/Computer it'll gain access during a (drop-out).
This is weird because I run DHCP on my modem.

So my network setup is this.
I have a Arris TG852, it's my main modem(ISP Modem/Router Combo). (ROUTER X)
I also have a Gigabit Lan Switch(Used for controlling the ethernet ports in the walls). (SWITCH)
Then I have my router that's running DD-WRT it's a WDR4300 from TP-Link. (ROUTER Y)

ROUTER X, runs an ethernet into SWITCH, SWITCH runs two ethernets into two wall sockets.
1 Wall socket leads straight to a PC.
The other wall socket leads to ROUTER Y.

ROUTER X Controls all DHCP requests and everything like that, it's set-up like this:

WAN IP: ENABLED
LAN IP: 192.168.0.1
SUBNET: 255.255.255.0
DHCP SERVER: ENABLED
OPERATING MODE: GATEWAY
WiFi Ath0 (2.4Ghz): AP, Mixed WiFI Mode, Dynamic 20/40, WPA2 Personal.
DNS SERVER: AUTOMATIC
DHCP RESERVATION: Only one IP is reserved being the second router.
FIREWALL: ENABLED.
UPnP: ENABLED.

ROUTER Y is set-up like this:

WAN IP: DISABLED.
LAN IP: 192.168.0.x
DHCP SERVER: DISABLED.
WAN PORT ASSIGNED TO SWITCH: ENABLED.
OPERATING MODE: ROUTER
WiFi Ath0 (2.4Ghz): AP, Mixed Wifi Mode, Dynamic 20/40, WPA2 Personal.
WiFi Ath1 (5Ghz): AP, Mixed WiFI Mode, Dynamic 20/40, WPA2 Personal.
DMZ: ENABLED. (So i'm not double nat'd with my other router).
FIREWALL: DISABLED.
UPnP: DISABLED.

Now as you'd know, this gives me 3 AP's (Access Points).
AP1. (ROUTER X)
AP2 & AP3. (ROUTER Y)

This doesn't annoy me much at all having 3 AP's. But If I could have them all as one AP and still get full WiFI speed, that'd be great.

ROUTER Y Is in my room, my side of the house to give its WiFi to Phones and Laptops on my side, while acting as a ethernet switch and cater to everyone in my room.

ROUTER X Is in the middle of the house, catering it's WiFi to anyone that can reach it and have a nice signal. While having an ethernet run to a EoP(Ethernet over Power) that runs to IPTV(FetchTV) 2 Meters away from it. Then another ethernet running to (SWITCH)

We have up to 15 devices at any given time connected. I don't know if this is useful information to know, just trying to give you everything I can give you so you have all the information you need to answer my question, which is why is my DHCP not working and assigning IP's correctly?
It's just the WiFi pretty much all the time it screws up with but sometimes the Wired connections drop out as well, this is pretty frustrating being that I have LANs all the time at my house and when we are in the middle of a game the internet drops because of an unassigned IP Address.

But if I assign Static IP to the devices they're fine.

Thanks in advance, hopefully someone can help, I'm not a network genius nor do I have any qualifications or anything just like to dabble in it as a hobby.

Think I fixed this my self just now, Router X, for the DHCP server started at 192.168.0.2 While Router Y Was assigned 192.168.0.4 in the DHCP Reservation list, just changed it to 192.168.0.2 then changed the DHCP Server to start at 192.168.0.3. I must have missed over this setting awhile back.
