Re: Should I buy an "N" router?
If G works where N (especially dual-band N) does not, then there is something decidedly unusual about the area you are in.
1. Are there a lot of DECT cordless phones in the area? (Most newer DECT phones use the same 5 GHz band that high-band N devices use; the older DECT phones, and most cordless *standard* phones, share the 2.4 GHz band with N and wireless-G.)
2. How many other wireless-N networks are there within range? (Multiple N networks operating on the same channel, even with encryption, are going to have crosstalk issues; the same issue applies to G, of course.)
From what the poster with the range-gate issues with N was commenting on, the first (DECT phones and lots of them) is more likely (since his issue was with dual-band N, which was created to avoid a similar issue with older cordless/DECT phone systems in the 2.4 GHz band that is shared with these devices and wireless-G). |

Not true.
DECT phones will not interfer with A,B, G or N. They operate entirely outside of either the 2.4GHz or 5.8GHz bands.
Cordless phones in the US can operate at 900MHz, 2.4GHz or 5.8GHz, but none are DECT.

The original DECT frequency band (1880 MHz–1900 MHz) is used in all countries in Europe. Outside Europe, it is used in most of Asia, Australia and South America
In the United States, the Federal Communications Commission in 2005 changed channelization and licensing costs in a nearby band (1920 MHz–1930 MHz, or 1.9 GHz), known as Unlicensed Personal Communications Services (UPCS), allowing DECT devices to be sold in the U.S. with only minimal changes. These channels are reserved exclusively for voice communication applications and therefore are less likely to experience interference from other wireless devices such as baby monitors and wireless networks.
The above is taken from the following link:

From the documentation, GE's DECT phone system operates in the 5.8 GHz band (and it's a residential, not business, DECT system aimed expressly at US homes).
However, the same issue would still occur with traditional 5.8 GHz devices if you have too many on the same channel (that is why it makes sense to avoid channel 6 with 2.4 GHz N or G, entirely because it's a default setting, and thus often used). |

| I only found one manual for a GE DECT and it specifies the 1.9GHz band.
»www.google.com/url?sa=t&source=w···hLw_yj_Q
All of the other online references to GE DECT I looked at (about 10) list DECT 6.0 as the operating frequency. Again, 1.9G.
Not trying to pick a fight, just making sure we're all on the same page so someone looking for a phone isn't steered in the wrong direction. If you want something with no chance of interference, buy an old 900MHz (hard to find any more) or DECT 6.0. Others can be a problem. |

An additional datapoint:
I directly replaced my WRT54GS with a WRT310N (there are no N devices on the network), keeping the same security settings and passphrase (different SSID, however). The same devices connect without issues. It is for precisely this reason why (barring other issues, such as cross-compatibility) I'd find it incredible to believe that G would work where N (even draft-N) would not.
The router in question is not a new WRT310N, but a WRT310N that was surplused by a family member I had done some network jobs for when their ISP (VZ) replaced their wired-only DSL router with a wireless-G router. (The only wireless devices are wireless-N; however, I foresee no issues for the same reason the N router will have no issues with G devices; backward compatibility.) |

I use both 5.8GHz and DECT 6.0 (1.9GHz) with a N network DECT 6.0 phones seems to work better. A lot of the 5.8GHz are really 2.4GHz even though they claim to be 5.8GHz and some brands go even cheaper and make the 5.8GHz a dual band but not with 2.4GHz and actually 900MHz. You should check the specs or contact the DECT 6.0 phone maker before you shell out money for such a phone. |

No.
Esp. don't buy a Netgear WRN2000 because it simply doesn't work.
I spent days loading wireless drivers and even re-loaded ubuntu... (based on other people's apparent issues) but to my horror, but not surprise, I have found that my laptop connects at every wireless hotspot and today I connected to a wireless g router without issues. So it seems I have wasted my money and I cannot get any support from netgear.
So much for wireless N being backwards compatible... |

I just installed a 11n router (TRENDnet) and a TRENDnet adaptor for my laptop. The router cost $27 and the USB adaptor $49. The router is a dual antenna and replaced my Linksys G only router (the TRENDnet is g and n). My throughput speed on my laptop is more than doubled (but not 300mbps, only 130mbps). I know, this is brand new stuff, not New Old Stock or anything. I am using Windows Vista on my main computer which is wired to Comcast cable. Laptop uses XP. It has been stable for several days. The Linksys was stable at 54mbps 24/7 for over 4 years. I am keeping it for a backup.
I did try a Dlink 11n router and it would not stay connected. It went back. |

Throughput or wireless connection speed? Quite different. |

| Using a Dell Inspriron laptop, Windows XP, and a Trendnet TEW-664UB USB adaptor on my upper floor and a Trendnet 11n wireless router on my first floor I am seeing Physical Layer Speeds of 270.0 Mbps since I reconfigured my router.
I know it is advertised as 300Mbps but I just haven't tweaked that high of speed out of it.
It is noticeably faster than my 11g Linksys router (which only showed 54Mbps).
Should YOU buy an 11n router? Only if you want higher speeds on your remote device. For under $100.00 you can more than double your speed. I have had this on 24/7 for over 1 week with no loss of 100% signal. |

2 edits | IP throughput (your useful speed) is abouty 60-70% of the raw wireless bit rate, e.g., the best 11g can do is about 24Mbps.
11n speed depends on how compatible vendor A and B are if you have mixed vendors in the access point/router and clients, if there are any non-11n clients slowing things, if your hardware and interference condition can permit channel-pair-bonding, and many other factors. It will vary day to day.
Of course, we all know that speeds well beyond what your Cable Modem or DSL or other means your ISP uses are not important- except for inter-PC data on the LAN. Windows file shares are hard to run at very high speeds due to overhead in windows. |
