Alright so I ordered one of the best internet plans I can get where I live which is Unlimited/month 50MB/s Down and 5MB/s UP speed. They included what I have been told is a very nice Modem which is the Arris TG862g. I did a little research and found out it's a gateway, which I believe (don't quote me on this, novice here) is at it's most basic description a Modem and a Router in one unit. Now I pay quite a bit of money per month for this service and on my Gaming Rig I have the speeds I was promised, no problems there. However my PS3 is downstairs, on the other side of the house. It connects to the internet but I lag out playing games Like Call of Duty or Battlefield. I have horrible lag and sometimes completely disconnect. I am willing to invest at tops $200 in a router and found the "Asus RT-AC66U" router. Linked here. I was hoping that not only would this help boost the signal to at least fully reach the PS3. But also improve my speeds wireless as well. However I don't know if I can connect a Gateway to a Router so my questions are these:

1. Can I even connect my DSL Gateway to a Router?
2. Will it improve signal range and/or wireless speeds.
3. Is the Router I found overkill, would I get better quality for less (I'm looking for the BEST I can buy for under $200)
(if 1=yes)4. How would I go about hooking up my Gateway to my router?

Other Things:
-Up to 5 Wireless Devices and my Desktop regularly use this internet at the same time
*Even if none of these are running the PS3 still lags
-I don't want to spend more than $200 on a router, but if the Asus router I found isn't good enough I can pay more for another router if that's too much**
**The other wireless devices are mainly used for just browsing the internet but one of them belongs to my roomate who games regularly.

Nope, only on the new device. Leave it enabled on the Arris device. You will want something that provides that service on your local network.

Okay, there is a lot going on in your post.

Can you run an ethernet cable to your PS3? You can get a hundred feet of cable, a crimping tool, and a few RJ45 heads for under $50.00 and you won't have to deal with lag unless it's your internet connection.

1) You can connect your second wireless router to the Arris TG862g... but you need to have some idea as to what you are doing. Most devices like the Arris have the ability to have their mode changed. Also, you will want the Arris to be the DHCP server and your default gateway.
2) It will improve your range/wireless speed if it's in the correct position and set up properly. Water, microwaves, wireless land-line phones and a plethora of other devices cause wireless interference.
3/4) Basically, disable DHCP and point the new wrouter (wireless router) to the Arris as the DHCP server. Set the default gateway to the wrouter and give the wrouter a static IP address outside of your DHCP range.

Like I started the post off with, it's easier to run a long ethernet cable. Remember the maximum recommended range of an ethernet cable is about 100 m without some type of repeating device.

Also, can you move your Arris device to a more centralized location?

Thanks for the reply! I can't move the modem itself because when I had the cable company come set it up they said that (Where it is currently located) is the only spot in the house that can have the modem (something to do with interferring with the phone package I also ordered, wasn't too clear on what they meant). I can't really run a cable to my PS3 because it would go from the office it's in to the door, down the hallway, down the stairs (long staircase) around where the stair case is to the living room and all the way across the living room. If I could move through walls the distance from the modem to PS3 is probably still 50 meters, actually running it there would be much longer.

I understood most of your post and if I can't figure it out when/if I order that Asus Router then I probably won't hate my life too much if I have to call the cable company to pay a visit to my house and help things get set up (though I'd like not to have to deal with 2 weeks in advance scheduling and paid visits)

Edit:
A little extra info. By configuring the gateway to stop acting as a router, and solely a modem would deselecting "Enable Wireless" suffice or no? (This is a setting on the actual router configuration page at 192.168.0.1)

2nd Edit:
I was looking at something a friend recommended. If someone is still out there, mind checking this out: ASUS EA-N66 would this solve my problem?

I looked at the Asus EA-N66. It's a 3/5 egg item on newegg so people have had issues with it. Read the reviews.

What you will want to do is put whatever wireless router you get in Access Point mode (some do not have this feature) and give it an IP address of 192.168.0.2 (95% chance that this is out of your DHCP range).

Deselecting "enable wireless" will not suffice for making the gateway stop acting like a router. It will be much easier to leave the "gateway" (Arris device) alone and reconfigure the new device (either Asus device) not to use DHCP. You will have to change the Asus's default gateway to 192.168.0.1.

So your saying that instead of doing a bunch of configuration on the Arris (what would be the modem) I should just configure the Asus Router to not use HDCP and change it's default gateway to the IP (192.168.0.1) of the modem, while it's connected to the modem?

That's what I am saying. Make sure to give the Asus router an IP address too. Basically, your network settings on the new device should look like this.

IP address: 192.168.0.2
Subnet Mask: 255.255.255.0
Default Gateway: 192.168.0.1

You should disable DHCP on the new device too.
