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.]]> http://www.dslreports.com/forum/Re-Should-I-buy-an-N-router-22996784 Wed, 09 Sep 2009 14:47:31 EDT Re: Should I buy an "N" router? http://www.dslreports.com/forum/Re-Should-I-buy-an-N-router-22993867 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. ]]> http://www.dslreports.com/forum/Re-Should-I-buy-an-N-router-22993867 Wed, 09 Sep 2009 00:21:10 EDT Re: Should I buy an "N" router? http://www.dslreports.com/forum/Re-Should-I-buy-an-N-router-22993742

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...]]> http://www.dslreports.com/forum/Re-Should-I-buy-an-N-router-22964561 Wed, 02 Sep 2009 17:44:56 EDT Re: Should I buy an "N" router? http://www.dslreports.com/forum/Re-Should-I-buy-an-N-router-22947516 http://www.dslreports.com/forum/Re-Should-I-buy-an-N-router-22947516 Sun, 30 Aug 2009 14:50:26 EDT Re: Should I buy an "N" router? http://www.dslreports.com/forum/Re-Should-I-buy-an-N-router-22917853
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.)]]> http://www.dslreports.com/forum/Re-Should-I-buy-an-N-router-22917853 Mon, 24 Aug 2009 19:08:00 EDT Re: Should I buy an "N" router? http://www.dslreports.com/forum/Re-Should-I-buy-an-N-router-22909464 »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.]]> http://www.dslreports.com/forum/Re-Should-I-buy-an-N-router-22909464 Sat, 22 Aug 2009 17:53:20 EDT Re: Should I buy an "N" router? http://www.dslreports.com/forum/Re-Should-I-buy-an-N-router-22909413
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).]]> http://www.dslreports.com/forum/Re-Should-I-buy-an-N-router-22909413 Sat, 22 Aug 2009 17:41:17 EDT Re: Should I buy an "N" router? http://www.dslreports.com/forum/Re-Should-I-buy-an-N-router-22909288
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.

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.)

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.

1. Wireless devices - upgrade as many to N as possible (preferably all). A network is typically only as fast as the slowest connection, and the slowest connections on any N network will be wireless. However, that connection should be no worse than single-band N, not G, and certainly not B!

2. Wired connections - upgrade as many to gigabit as possible; if not possible, upgrade them to wireless-N. The reasoning is the same as above (the network is only as fast as the slowest connection).

3. Any wireless-N router should be, at minimum, dual-band simultaneous (MIMO-N) and have gigabit WAN *and* LAN ports. USB-based NAS at the router is needed if you have two or fewer wired gigabit devices connected to it; however, it usually isn't if you have three or four. (Any PC will have more USB ports available, even without external hubs, than USB at the router. At-the-PC connections also allows the option of external SATA (eSATA) which is far faster than USB for NAS.)

4. Last, and far from least; remember the raison d'etre for N. Wireless-N (compared to wireless-G or any other LAN standard) is all about connection speed *within the LAN*. Wireless-N (in fact, no LAN standard) can't do anything about external bottlenecks (so not even wired gigabit can ameliorate a server-side bandwidth crunch).

Recommended residential N router - Linksys by Cisco WRT610N.

Why this router - First off, it meets alll the requirements I laid down (all wired ports are gigabit, supports MIMO-N); second, it's easy to set up (as are most Linksys routers; I've set up the little-brother WRT160N, which has for some reason given a lot of reviewers pain, and I found it easier than setting up my personal WRT54GS, which I've had for four years); lastly, it's relatively inexpensive (even at full retail, it's almost never $200).]]> http://www.dslreports.com/forum/Re-Should-I-buy-an-N-router-22908761 Sat, 22 Aug 2009 14:54:23 EDT Re: Should I buy an "N" router? http://www.dslreports.com/forum/Re-Should-I-buy-an-N-router-22846877 http://www.dslreports.com/forum/Re-Should-I-buy-an-N-router-22846877 Mon, 10 Aug 2009 21:11:41 EDT Re: Should I buy an "N" router? http://www.dslreports.com/forum/Re-Should-I-buy-an-N-router-22822800 I suggest to buy a Trendnet TEW-633 N router.

For me, there is no benefit. Most of the traffic is to the internet, with little between LAN machines. And the bottleneck for internet traffic is the ISP, not the local wireless.

If you have a small home [under 1,500 square feet] then you would buy the Belkin N+ and the Belkin "N" Wireless Notebook Card. If you have a large home [2,000 or more square feet] then you would buy the Belkin N1 vision and the Belkin "N1" Wireless Notebook Card

The N+ and N Notebook Card should cost you $200 or less. The N1 Vision and N1 Notebook Card should cost you $300 or less.

Yes, if properly configured then you should see a significant difference.

IMO, the Intel WiFi Link 5100 AGN technology will not provide you with long term satisfaction -- so if your objective is [a]performance via greater bandwidth and speed [b] greater range and [c] superior interference handling THEN you need to match technologies being used at the Router and at your HP HDX18 Q9000.

If you want to take advantage of "N" today then look at the Belkin N+ and the matching N Wireless Notebook Card [using 2 x 3 radios/antennas etc.] or the N1 Vision and the matching N1 Wireless Notebook Card [using 3 x 3 radios/antennas etc]

The KEY phrase is matching. The 2 WiFi Routers and matching Network interfaces I mention above us MIMO technology from a CHIP makes called Ralink. The Ralink MIMO system being used by Belkin in the products I mentioned is decent [not great like Airgo now Qualcomm tech] . The N1 Vision and its matching N1 Wireless Notebook card work better in larger homes because the N1 Vision and its matching N1 Wireless Notebook Card use 3 x 3 radios/antennas etc.

IF you do NOT match the technologies being used your level of satisfaction with the products will be far less.
Atheros N 2T2R and 3T3R MIMO chips are not as stable I have those devices also prior to the Ralink for N. Marvel N 3T3R MIMO no good. Broadcom N 3T3R MIMO still not convinced, I have that too. I have no issues using Ralink N with Realtek 8190 2T2R adapters.

Everything has to work together and don't believe you need to buy matching adapters for G or N. I've use Buffalo G/N routers/ap with Belkin and Buffalo adapters they work. I use Buffalo/Belkin/Trendnet adapters with Belkin N+ and works great! None of these adapters have Atheros! Once you introduce Atheros Router/AP issues happen. Still Intel wi-fi works with Belkin N + without issues.

Why? without these critical technologies your "N" system [be it a Router or AP or any combination of either] will not give you the performance that you may expect or want.

The critical technologies are:

[1] 3x3 MIMO --- 3 transmit | receive radios and 3 antennas [3 of each minimum]
[2] Spatial Multiplexing
[3] Incorporating ASIC routines that exploit multipath.

What makes MIMO very special is when [1] is combined with [2] and [3] if its done the right way. There are multiple forms of MIMO and each CHIP promoter has their own unique way of doing MIMO regardless of what you may have read about the standards group have set for 802.11n

Spatial multiplexing allows for the transmission of multiple distinct data stream's over multiple radios in the same band at the same time, effectively doubling [or tripling or more] data throughput. Think of it as sipping water through two [or more] straws at once. Specifically, devices that exploit MIMO chipset and RF technology transmit two [2 or more] distinct datastreams simultaneously. This is what gives you the bandwidth that needed to Stream HD Video, Listen to digital music, Play online games, Transfer photos and home videos, Handle multiple VoIP phone calls for more than 1 person at the same time.

Properly implemented MIMO systems divide a data stream into multiple unique streams, each of which is modulated and transmitted through a different radio-antenna chain at the same time in the same frequency channel. By taking advantage of multipath, reflections of the signals, each MIMO receive antenna-radio chain is a linear combination of the multiple transmitted data streams. The data streams are separated at the receiver using proprietary MIMO algorithms that rely on estimates of all channels between each transmitter and each receiver.

Each multipath route can be treated as a separate channel creating multiple "virtual wires" over which to transmit signals. MIMO employs multiple, spatially separated antennas to take advantage of these "virtual wires" created by multipath and transfer more data. In addition to multiplying throughput, range is increased because of an antenna diversity advantage, since each receive antenna has a measurement of each transmitted data stream.

IF the "N" system you purchase does not incorporate [1] [2] and [3] I would speculate that YOU will be very unhappy with the performance of the system within a short order of time.

The only CHIP promoter that I know off that does "N" the correct way -- where you will derive a great deal of satisfaction is Airgo now owned by Qualcomm.
Is Airgo the uncrowned king of 802.11n MIMO?

if your network stops when your microwave is on, sell your microwave and upgrade your network to "n".

That made me chuckle and I heartily agree.

A couple of years ago, we did a kitchen remodel that included new appliances. The "old" ones still seemed pretty new to me as the house was new when we moved in and they all still worked fine after 12 years or so.

My laptop would slow noticeably when the microwave was running. I assumed that was pretty typical until we installed the new one. Now, I get no slowing at all. Makes me wonder how much RF I took to the noggin.

The whole "Should I buy N?" debate will soon become moot. Prices are dropping and someday there will actually be a finalized standard. Right now, though, it's still a valid question. I appreciate the thoughtful input.]]> http://www.dslreports.com/forum/Re-Should-I-buy-an-N-router-22455717 Wed, 27 May 2009 23:35:20 EDT Re: Should I buy an "N" router? http://www.dslreports.com/forum/Re-Should-I-buy-an-N-router-22455449
do you have issues with interference with your 802.11 network?

if your network stops when your microwave is on, sell your microwave and upgrade your network to "n".

If your neighbor's garage door opener makes your network go wild, upgrade to "n".

are there specific times of the day that your network appears to struggle to get anything through, either up or downloading? if so, think about trying "n"

IF you decide to go the "n" route, be sure you are buying the 5GHz flavor, and not the 2.4GHz flavor, and that you get the proper matching PC card for your client devices.

as far as speed goes, your home network is probably already faster than your home internet connection will be for some time to come so speed is a bad reason to change to "n"...

hope this helps.

Worst one on the list above is Atheros chips I have nothing good to say about them. Broadcom, Realtek and Ranlink are just fine. Netgear and Linksys use Broadcom and Belkin Ranlink, Trendent Realtek in wireless adapters. Dlink and Trendent uses the Atheros more. That's where the WLAN and WWAN have the most issues.

G/N-WLAN/WWAN LAN/WAN 10/100/1000 Ports
1. DIR-655 A3/1.22B05 firmware
2. DIR-655 A4/1.22B05 firmware
3. WRT-310N (used with dd-wrt v24/sp2/11650 firmware)
4. WNR-854T

G/N-WLAN/WWAN LAN/WAN 10/100 Ports
3. TEW-652BP v1.01 (used with dir-615 c1/3.01 modded firmware)
4. WNR-834Bv2 (used with dd-wrt v24/sp2/11650 firmware)

Notes:

DD-WRT
WRT-310N and WNR-834Bv2 needs special firmware to first be installed. WNR-834Bv2 needs 11650mini.ck flashed first then 11650std.bin. WRT-310N needs mini.bin then the std.bin flashed.

TEW-652BP stock firmware 1.10.8 it's okay but limited. So a header files was put onto the DIR-615 C1/3.01 firmware so you can flash the 652BRP to a DLINK firmware. So you have WAN port speed 10/auto/10/100/100 instead of not having that option.

This router it pron to heat so it has a bad case design where the air vents on the bottom. You would need to stand it up on it's side leaving the bottom part exposed. Even though you can mount it on the wall the air vents would be blocked and causes the unit to over heat.

DD-WRT firmware is WIP (work in progress)
Latest firmware can be found here for DD-WRT

Here is a quote from the link that references the feature:

"The transmitting WLAN device actually splits a data stream into multiple parts, called spatial streams, and transmits each spatial stream through separate antennas to corresponding antennas on the receiving end. The current 802.11n draft provides for up to four spatial streams, even though compliant hardware is not required to support that many."]]> http://www.dslreports.com/forum/Re-Should-I-buy-an-N-router-22015061 Wed, 04 Mar 2009 17:51:57 EDT Re: Should I buy an "N" router? http://www.dslreports.com/forum/Re-Should-I-buy-an-N-router-21995497 http://www.dslreports.com/forum/Re-Should-I-buy-an-N-router-21995497 Sun, 01 Mar 2009 10:54:53 EDT Re: Should I buy an "N" router? http://www.dslreports.com/forum/Re-Should-I-buy-an-N-router-21995375 said by No_Strings:

Yes, that's what I'm saying.

If the hardware (CPU/RAM) of the G router is a bottleneck - that is, it can't process the bits quickly enough and the N router has more internal horsepower, then it's conceivable that you could see improvement.
...
In neither of those cases would the N spec in and of itself help. A more robust G router would produce the same results.
This is not true. Draft N 2.0 with two or more antennas create spacial zones with full G speeds. Look at it like two to four g routers back to back covering a 90 degree zone to fill all 360 degrees. Each zone can send and receive concurrently with the other zones with no radio impact. It's kind of like the move from hub's to switches with copper. So, if the clients are connecting to different zones, they are not sharing airtime, therefore, performance IS increased. The amount of increase will depend on the specs of the router, but most Draft N will perform much better then a G router.]]> http://www.dslreports.com/forum/Re-Should-I-buy-an-N-router-21995375 Sun, 01 Mar 2009 10:17:52 EDT Re: Should I buy an "N" router? http://www.dslreports.com/forum/Re-Should-I-buy-an-N-router-21988131

If the radio on the G router were so crappy or degraded that it was slowing things down due to retransmitted packets, then it's again conceivable that a new router could help.
