Is it worth it to buy a Wireless N router?

To receive any benefit whatsoever all your devices would have to be 802.11N capable and you would likely have to pay your ISP much more than you presently paying. If you didn't most N devices can also do 802.11G and you would see zero net benefit

If none of your devices support Wireless N then there's not much point in buying a Wireless N router, unless you expect to upgrade the other devices at some point. It sounds like what you really need to invest in is enough ethernet cable to put your router in the middle of the house, so that all of your devices are in range. It's also worth remembering that the advertised range of a router takes no account of walls and other obstructions, which will drastically reduce the range. If you do decide to upgrade then get one with gigabit ethernet too.

Remember too that if the signal has to travel diagonally through a wall between the router and the device then this could be much the same as it passing through two walls.

I think you first need to do this:

Disconnect all the devices and only get one and do a speed test, then do it with a computer by ethernet, look the numbers and see if really the problem is the router. Also do the ethernet test ehith all your other equipments. This is to see if the main problem is the router and not your local conection or your internet provider. You have more than one device but 5 or 6 devices are not too much.

If the problem persist or your HD media streaming (this in fact may be caused by the poor quality signal or old router) still bad, then is the moment to upgrade. (verify the top speed your router provide over your internal network)

I think your problem is a bad location of the router or your Internet service provider.

(An upgrade is not bad, but maybe you have better things to expend your money)

I would definitely suggest an upgrade, but I'd skip the N. My suggestion is save the money and instead buy another wireless G router but with range booster (linksys makes some very good high range routers). The price will be close to the same, but you'll be able to fully use the G while also getting better signal over your entire house.

look into a boosted antenna for your existing router instead.

your next generation of wireless devices will be N type, and that might not solve the problem with existing G or B devices. The problem is the signal isn't strong enough

N+ and similar technologies only get the large range when connecting to similar devices, or so i'm told.

The wireless N should be compatible with your xbox and your ps3, and yes, the it really does reach far and because it's N, it'll be more powerful and go through walls better, even if you don't get the speeds.

Don't buy a Belkin, though. You're gonna want Linksys. I went through two Belkins in 6 months, and have used a Linksys for about a year with zero problems.

I'd go for it and check the stores return policy. Make sure you can return it for an exchange or refund if you don't like what it does.

I'd move the current router to the middle of the house & wait a while (6 months or so) until more IPv6 routers become available, then go with the N series.

Yes, for your uses definitely. Gaming, HD content, and 8-10 devices is pretty demanding. Although N isn't completely necessary, it will give you super fast speeds.
