I am going to look into getting something bigger. I do not know much about routers as I have not needed one in a while. I am currently using an AT&T U-Verse modem with a built in router.
Any specific suggestions?

...never been a huge fan of those combo devices. I just upgraded from my older
Netgear WNDR3700, which was a pretty good router overall. I had very little trouble with it, but it was always a gamble whether Netgear's latest firmware was worth flashing. I think I'm using an older firmware that had less reported connectivity problems (note: I don't have any), but the Attached Devices section never works.
I'm currently using
The Nighthawk. (I just like saying that. I'm also waiting for it to mess up so I can say, "Nighthawk down!" :biggrin

Anyway, routers like that are probably overkill. Although, I am a fan of external antennas as they should provide better coverage (kind of like how they were better on cellphones).
Your best bet would probably just be to wait about a week for some good Black Friday deals on Newegg or Amazon. Also, keep your eyes peeled for anything good on sale leading up to it. I'd probably look for a good, quality 802.11n router, but just don't skimp on it. It's rare for me to pay below $100 and get a good router (unless it's on sale). Unless we're talking about the old Linksys WRT54G.
i game on 140" 1.78 and watch movies on 170" 2.35, there is a major difference between 720p and 1080p. i need 4K resolution. please stop gaming on TVs.
The cost for me to setup a
passive 3D-capable projector setup combined with being in an apartment makes a projector a
terrible idea.
The thing is, if average joe walks in from the street and sits 10 feet from a ~40 inch tv...
...there are still people out there that from 20 feet can't tell they are watching DVD from Blu-ray.
The people in your examples need to sit closer to the TV, because that's
way too far away.
The real question is, does the reduction in quality make the game less enjoyable?
That depends a lot on the aim of the game. If a game is going for realism, then increased graphical prowess, which
can affect more than just resolution, can be quite the advantage. Frankly, I would really have liked to see Dead Rising 3 on the PS4 just to see if the increased power would've given the game the grunt it needed to not suffer from slowdowns and maybe just be a bit prettier.
