Default G Router & N Router...Difference???

Need a little clarification if you guys don't mind please. And please speak in laymen's terms for a novice here...please!

My question is will G & N routers work the same with any computer?
I am under the impression that the only real difference between a G or N router is the speed. But I keep hearing this guy say that if you got a G router & a computer with a N wireless card it won't work very well or vice versa.

Any help would be greatly appreciated!

Most wireless N routers/cards (that I have seen) will also support the slower B or G speeds as well. If you have a N router and G card, it will simply transfer at the slower B/G speeds to the card. Just check on the box and it will tell you what they support. If you have a N wireless card in your laptop I would get a N router if you can afford a new 1, but no biggie if you cant. You won't see much if any difference with internet speeds since yours will be under 50mbps, but you will notice a pretty big diff with network file sharing between computers or streaming to your 360/PS3 and stuff like that on your network. N will also give you increased range in many cases too.

Get a router that supports both G and N. Problem solved.
http://www.newegg.com/Product/Produc...82E16833127241

$40 and for a limited time get a spare PC card for free.

The problem is without knowing what network card you have, it's impossible to answer your question. It's like a radio, MOST FM radios offer AM. There are a few exceptions, mostly a few car stereos from the 1970s designed to share a dash with an existing AM.

I think there were some wireless-N only PCI cards, but these are rare. I've NEVER seen wireless-N only in a laptop.

I should have been more specific I guess as it's not about my router as I have an N router & N Card.

What is going on is there are a few of us that play in an xbox party almost every night. One guy has been complaining about his speed.Well the guy mentioned in the OP tells him because he has a G router & a N card he will never get his speed. And he says it's the same vice cersa with a N router & G card.
Well from what I have read the G router supports a speed up to 54mbps so no matter wich card he has G or N he should get 54mbps.....right?.....plus his ISP only offers a max speed of 54mbps.

So I just really want to tell this guy he is wrong but I can't because I could be wrong being the novice I am & this guy has messed with computers since the mid 90's & thinks he is never wrong.

That is correct. As I stated above, if he has a G router and an N card, it will work fine. Pretty much all N cards/routers I have seen also support B/G as well. It will just be transferred at the B/G speed of 54 mbps max instead of the faster N speed of 300 mbps or whatever it is. But that will mattet little if at all since he is limited to 50 mbps internet service. Bu if he was say: streaming video or large files between his PC and 360 he would see a big difference in speed. But 50 mbps is a balzing broadband speed so not sure what he is seeing or complaining about. Is it during certain games? Is it lagging out or slowing down. If so, I doubt it because he is on G speeds and not N. Something else is going on with his network or connection or something.

I only have 3mbps DSL and G wireless. It does fine on XBL and little to no lag issues at all (other than very recently since my DSL modem is acting up). So 50mbps and G will be waayyyyyyy more than needed.

Actually the guy with the problem doesn't have a problem with getting a speed of 54mbps from his ISP. It's that he can only get a download speed of usually 4-5mbps when the ISP says you will get download speeds of 8mbps.....So the know it all guy says the problem is because of what I have typed in the previous post...G doesn't work well with N either way. So that is why he tells him to go buy new stuff.
I say if he is getting 54mbps from his ISP then any changes are not gonna make his download speed of around 4-5mbps go up to the 8mbps that the ISP offers. I just don't think having a G/G setup or N/N setup is gonna make a difference there imo & that his G/N setup is fine.

Hence why I came here to get some good knoiwledge in laymen's terms(wich I thank you for) so I can explain it to my friend & save him some cash.

Not to nitpick, but you are bouncing some terms around here. Let's get some definitions:

ISP is the internet service provider that says he can get "up to 8mbps." That's important, notice that the ISPs all say "up to."

He connects to his ISP via a router or modem or a combination of both. He is probably getting 54mbps between his computer and his wireless router. Between the router and the modem (depending on if he has cable or DSL etc) he is probably getting 100mbps as that is pretty typical of modems.

The problem is that between the modem and the ISP he is only getting 4-5mbps. That is not unusual, but has nothing to do with his wireless system. The reason the ISP uses terms like "up to" is because they are at the mercy of the demand on the system and the physical cabling out in the world. More people using their system tends to slow the whole thing down. So in reality, the problem is more likely his ISP not anything on his system.

At least that's the guess I'm making based on what I'm reading here.

So it's like this:

PC <- 54mpbs -> Router <- 100mbps -> Modem <- 4-5mbps <- ISP

I am a bit confused.. Does he have 8mbps service or 54mbps and from what ISP?? I have only seen 50mbps offered in very limited fasion and for $$$$, so I assume 8mbps service is what your friend is getting. If so, his average 4-5 mbps download speed seems about correct for that type of service if it is cable. As Mob pointed out, "up to" with a * is the common term with download speeds and speed choices. With cable, a few things will determain overall download speeds like the number of people on the pipline hogging bandwith and stuff like that amounst others. So you will rarely see the full 8mbps download speeds, but sometimes you may.

With my DSL for example, distance from the CO is the main factor. My DSL service provider offers "up to" 6mbps DSL, but I am too far away from the CO to qualify for that speed, so "up to" 3mbps is all they can offer me.. And doing DSL speed tests and downloading stuff, I usually clock in about 2.7-2.8 mbps.. If i would be able to get say 3.5-4mbps, they probably would still qualify me for the "up to" 6 mbps..

Ok I should have shutup after Biggloww ansered my question with Post #5. I am not able to talk the tech talk you guys do as I mentioned in my OP.

We have roadrunner wich offers up to 10mbps standard dowload speed. He gets only 4-5 & should get better I think.

We both have the same Netgear router & if you click on the status it says 54mbps next to speed....So that is where I get that # from.

Sorry for any confusion...I'm trying to learn

Thanks for everyone's help

Ahh, roger that.. The 54mbps is the router's G speed. If he is only getting about half of the 10 mbps "up to speed", it could be just the the avliable speed he is getting from the ISP. As long as he is getting good connection (bars) between the 2 wireless devices, it is probably the case.. You won't get 100% of the speed if you were wired.. Things like encryption (WEP) security will slow your wireless connection a wee bit, but nothing big.. He should test his connection to the modem with a e-net cable and and use a broadband speed test see if he sees any significant difference. My guess is he wont..

That speed is your lan speed, or your wifi speed. There is NO way as an end user to establish what speed the cable modem is running at, well, not unless your cable modem has an internal web page. If you were hooked in with a wire, you would see 10, 100mb/sec regardless of what roadrunner offers, or 1000mb/sec if you have gigabit routers.

Your cable modem acts alone, handshakes with your cable company, and negotiates it's own speed and doesn't tell anyone about it.

There "might" be an advantage to an all wireless-N network. Wireless-N can use some of the G frequencies, which would provide no advantage to a typical cable connection which typically maxes out at 14mbit, well below wireless-G speeds. If you're the only N kid on the block, there "could" be an advantage to moving to a frequency band that nobody else is using. But that has nothing to do with speed, that has to do with moving from a popular unregulated band to an unpopular unregulated band.

If your friend is considering shelling out cash, tell him/her to invest in a wire first. If there is significant improvement with a wire, investment in time and money might be justified. If there is little to no improvement with the wire, declare victory. The price of a 100ft network wire from Monoprice is $8.00 plus shipping.

Wireless-b (up to 11mbit) is more than adequate for most cable connections.
