| Should I buy an "N" router?
Seems like we get this question a lot, along with frequent misconceptions about range and speed. I'd like to tap the extant brain trust for some content then sticky it for newcomers to see.
So, please post your technical rationale for or against buying 802.11N. State any assumptions - upgrade vs. buy new, for example - brand preferences (tell us why, though) and personal observations.
Thank you. |

| in my opinion, you SHOULD buy an 11n router if you wish to fatten the profits of you local retailer and you don't have expectations for a good benefit for your $.
You should NOT buy 11n client devices that match the vendor/vintage of W-router, since it's moot that they too are 11n compatible if the w-router is lame. |

| The originator posted a question to which he already knew the answer, or he was giving us a big clue. NO!
The answer is NO, if you have not done any research and thus are asking, and if you have done your research then you NO the answer already (as per stevo). |

I dunno guys.
I find if you get recent, tri-antenna routers with recent client adapters, you'll get real-world improvements in range and speed, even in crowded signal areas (like my house.) - even single band N routers. Will you see "300Mbit?" only at the link level... but real throughput is 50% higher or better then 11g all else equal, in my home anyway.
Toss in gigabit (wired) router capabilities and for the price, the value isn't bad.
There, now the three of us have posted the same positions here that we've posted in every other N topic here at DSL

| Gigabit wired ports is obviously a big plus for some. Can you expound a bit on the extended range of the wireless? I see conflicting reports and have no experience to reference.
How much of an increase did you see? What's the RF landscape like there? |

Dartmouth, NS | The problem with N, is that approval has been given to systems that seriously degrade standard G units without appropriate safeguards. The standards to prevent this were either poorly written or not enforced. |

| I run a mixed N and G environment - I have 2 G routers, and a Dlink 655, all within 10 feet of each other.
The Gs are not degraded. At the same location, 25' and 2 drywalls from the AP, a G based card got 60%, "good" signal and 12-18Mb/sec throughput. Swapping it for an N card signal is 92-96%, "Excellent" - speed is 240-300 at the link layer, and throughput is 30-40Mb/sec (as measured by iperf) across the wireless link.
Range out to the farthest unit is only 50' and one exterior wall + 2 drywall... G is poor, 20-30%, N is Good to Very Good, 70-80%, speeds are 20-25Mbit for N, and 8-10Mbit for G. (Note G was there before, tested G before and after installing N, G performance identical - still use several G units in the house talking to a Linksys G router, without issues. N is used for higher speed HD Media streaming.)
I've done the site survey, there are 4 other G networks at 10-20% signal, and one at about 50% - I put my three networks such that they don't overlap each other (much)
My results in a residential single family home (but tightly packed homes!) have been pretty positive - more throughput (not 20X, but a solid 10-20Mbit more) and about the same signal boost as moving everything halfway closer to the AP.
This is all draft 2.0 stuff, perhaps thats better then the first wave of attempts?

well unless people buy a multi in multi out wireless adapter to go along with the Pre N it's a moot point. I would recommend PreN phase 2 as this will be the approved standard around 7 2009 the first poll had over 12,000 negative responses to the standard the second had less than 25% of the responses meaning that it's not going to change again. so feel free to buy N phase 2 it's going to be the standard just remember to also buy an N adapter or multi antennea adapter I use a linksys WRT54GX4 MIMO G router when I get a round tuit I'll get a multi antennea adapter right now I have 54G thru 3 walls and they are OLD lath and plaster walls I also have a version 1 wrt54g with open sourced firmware but it's been so long since I played with it I forgot whose lol

I have found "N" Routers stink.
I have tried several and in most cases the devices either connects G rather than N.
I made it connect to the N standard and got lousy unreliable signal/throughput.
IMO "N" standard or Routers/Cards are not ready for prime time.
IMO & Experience G using Atheros chipset seems to be a hair better than Broadcom. |

As helpful as this post was, it would *really* help if you told us which models you tried, what the environment was (mixed N/G/B, N -only, etc) and what testing you performed*. Saying "they stink" isn't very scientific, and hardly repeatable.
* for example, I have found that B & G routers stink, Powerline HD stinks, switches stink, laptops stink, desktops stink, vista stinks, etc. But without specific details, those are hardly helpful to anyone else. They're all true statements, too. Just try and prove me wrong! |

From the manufacturers' viewpoint, the 11n w-routers are great. Gets more sales going becuase the w-router market was saturated with 11g products. |

I have tried Netgear wireless N 2 models 360 = stinks
" Linksys wireless N 3 different product = Stinks
" D-Link Wireless products 2 models = Stinks
" Wireless N USB adapters D-Link/Linksys/Netgear = Stinks.
I could give you all the model #'s but if you are looking for a more comprehensive test try it yourself.
If you still want model #'s let me know & I will give you all the info.
I bough them and returned them to the store and told them they stink.
----------------------------
If you are not sure. If they are good do what I did buy and try and then post your conclusions. |

I just brought a WRT160N router. The only reason was so my Wii had an internet connection.
The Wii found the hot spot and was easy to get to connect.
Not sure how it will be for computing, but I might try it in a few months. My network is currently a combo network and power line.

There is no good single answer to that question. The answer depends on a number of factors, the primary one being how valuable to you is the added range and bandwidth offered with the N router.
N is obviously more expensive. A decent model will set you back $100 or more. You are considering the bleeding edge which tends to run up costs. Do you already have a G network up and running? G remains the sweet spot.
Also consider throughput you need to get your day to day work done. If you are only using the router for internet access then your ISP bandwidth and other remote servers/routers will be the limiting elements, not the wireless router you choose. For example, my ISP usually provides about 3 MB access bandwidth--far less than the throughput provided on a wireless G router. It would make little sense to go with N in this case.
On the other hand, if you have a server in your network which you access for fileshares etc. then it could be a different story. You may need the bandwidth that N provides, depending on what you are doing with the server and how many clients you are supporting on the wireless network.
I have considered upgrading to N, but see no real value to spend the additional $$ needed to do so. My G wireless subnet is working just fine for what I am using it for. It provides reliable service at reasonable throughput. The router that I use USR WRT5461 was purchased on sale for $9.99 with rebate. Really a no-brainer at the time. Most of my network remains wired. I use only 2 clients at most on my wireless subnet. The cheap G router works perfectly in my case.
So what are your circunstances? Budget restrictions? throughput requirements? range requirements? |

N routers after they get out of the Pre-Draft mode will give you 600Mbps, but 4th Gen of N for business is at 869mbps. Right now for the money you better of with N, but N wit wired 10/100/1000mbps is the way to go. All N routers will still do G. I doing G until N becomes more standard and out of the draft. Going from 100mbps for wired LAN to 1000Mbps is a huge jump. Still some devices just can't do GIG Ports, so you need to have mix bag of tricks. Next mix 100mbps with 1000Mbps on the same switch. So you would need to buy two switches on for 10/100 connected to router port 4 and another one for 10/100/1000 connected to the Router port 1.
I know some here don't like DLINK, I prefer DLINK routers. DIR-655 is rock solid. But I won't buy there switches as then tend to overheat. My choice would be NETGEAR PROSAFE or the rounded white ones GS series.
LINKSYS new black disc routers have some issues, so I'll won't recommend them also seem slower than DLINK in test.

| My client adapters aren't n, and some have weak transmitters
802.11n may be useful for some people, but it's moot for me. I have 6 wireless-capable computers in the house right now, as well as an Xbox 360 and an iPhone, and none actually support n. All are g/b (or a/g/b) or b-only.
I'll probably get n hardware later, but I'd rather wait for the prices to drop and the n standard to actually be approved before I start investing in it. By that time I might even actually own an n-capable computer. In the meantime I can purchase three or four 802.11g routers for the price of just one 802.11n router.
P.S. My current setup actually consists of four 802.11g routers, all bridged through powerline networking. (My network topology map is here. There are three routers in that map, but I also have a fourth one off the top of the picture at the end of the backyard.) One might argue that a high-end 802.11n router might be able to reach further than my 802.11g routers, but I doubt it, since part of the issue is my receiving hardware. My iPhone for example isn't likely to benefit that much from a stronger source signal since the iPhone itself can't supply a huge amount of power to WiFi. Battery life is precious. So even if n routers can go further, my existing hardware would still necessitate multiple routers. And like I said, none of my existing wireless clients are 802.11n capable anyway.

I would buy N because prices have come down significantly and they are at the same price level as G now (in the $35-$40).
At the same time, N is backward compatible with G devices and provides higher throughput and longer range. Moving files over wireless will be faster than G.
