WRT160N with 40 MHz channel width?
Just purchased a WRT160N version 3. I had some connection issues and restricting the router to use 20 MHz channel width only and using channel 11 solved them. The router now works wonderfully. As soon as I allow the router to use 20 Mhz or 40 Mhz channel width my laptop with Intel 5100AGN wifi loses connection about 3 times a day. Why is this?? I would like to use 40 MHz as it allows for faster speeds.

Unable to set 5ghz 80 mhz channel width on EA6500
Hi
My desktop pc has an Asus PCE-AC 66 PCI card (supports up to 1300 mbps wifi) and is only 5m or so away from the the EA6500 router without any obstructions - yet i cannot connect at 1300 mbps AC wifi. On the EA6500 router, i have selected 'mixed' as network mode under 5ghz (since i have some other devices which connect on wifi N on 5ghz) but if i select channel width as 80mhz, i have issues connecting to the 5ghz network on the desktop pc. The desktop briefly connects and under status it says lan speed as 1.3gbps but then it disconnects and i can't connect again. If i select channel width as 'auto' then no problems, the desktop can connect but lan speeds are only 400-600 mbps. Any idea why i cannot connect at 1300 mbps? I suspect i may connect at 1300 mbps if i choose network mode as 'AC' but then my other wifi N devices on 5ghz won't be able to connect.
CheersHi!
Is your EA6500 running on the classic firmware? Or have you already upgraded it to the Smart Wifi?
You mentioned that the channel width is at 80 MHz. Was the channel on Auto? You may try other channels & find the best pair for the 80 MHz Channel Width.
Also, check the Asus PCE-AC 66 PCI card wireless properties, whether it's maximized or was just set to N-only. This can be checked by going to Control Panel > Device Manager > Network Adapters > right click on the aforementioned adapter then choose properties > Advanced Tab > check under Properties List & corresponding Value. -
802.11ac 5Ghz Connect at 40Mz Channel Width?
MacBook Pro (Retina, 15-inch, Late 2013
I have a 15" Late 2013 tMBP running Yosemite. My router is a Buffalo WZR-1750DHPD running dd-wrt from the factory. Build 23709c for those that are familiar with dd-wrt. The router is dual band and has the ability to set 20/40/80Mhz channel widths. No matter what I do, I can get my rMBP to connect at anything other than 20Mz. To see how I'm connecting I use the Option + wifi icon in the upper right. As you can see it say 20Mhz.
I have the router set for 40Mhz on the 5Ghz band. I'm stumped.Hi!

WRT160N: Channel Width from 40MHz changes to 20MHz
Hello,
It's been a long time since my last post... but here I am again.
I have bought a Linksys WRT160N. I'm running the latest firmware v3.0.03.
I also have an Alienware with a Dell DW1520 (Broadcom chipset).
My issue is this one.
I set on the router to work at 20 or 40 MHz as Channel Width.
Check my settings:
And I get this status values on the router:
And this values on the computer:
As you can see, I get 20MHz and not 40MHz... So I don't get on my computer the 300Mbps... and get just 130Mbps.
After a router reboot, I get the correct values of 40MHz.
Check the router:
And the DW1520 WiFi card:
Here is a picture of the networks arround my router:
Any ideas what's wrong on the router?
Thanks for your thoughts.
Solved!
Go to Solution.Nothing is wrong. You have a lot of other networks in your proximity. The router will first try to use 40 MHz bands when requested until it finds that due to interference with all those other routers you'll get a more reliable and faster connection when using only 20 MHz bands. Thus the router reverts back to 20 MHz only.
That's exactly how it should work for best results... -
macbook pro retina 15 after update OS X 10.9.3 to 10.9.4 can't connect wifi with Channel Width 40 HMz
That's odd. I assume this is the 5 GHz band, right?
Have you tried changing the router to do auto 20/40?
Have you tried deleting and reconnecting to the wifi network? -
I have a new iPhone 4s. I have a home wi-fi network using Cisco Linksys2000 router with all settings per this article - phone will not see network if set to 5 GHz channel width - solution?? 2.4 works but is not optimal with other devices in home (computers; tivo). Have others seen this? Any advice is much appreciated.
Stephen Spark is right - your best alternative is to use a simultaneous dual band wireless router like the AirPort Extreme. Your Cisco Linksys2000 is not a dual band router, meaning that it will be constrained to operate at the slowest speed of all the devices on your network.
The AirPort Extreme's dual networks will support all your 802.11n devices as well as all your 802.11b/g devices on both the 2.4 and 5 GHz frequencies simultaneously. -
Ipad can't get maximum of 802.11n (40 Mhz channel, 300 Mbps)
Hi, Gens!
I have TP-Link 1043 with OpenWRT. My WiFi is 802.11n with 20 MHz width at 2,4 GHz and 40Mhz width at 5,2 MHz.
Encryption is WPA2 with AES
My laptop connects at follwoing RX/TX rates:
180.0 Mbit/s, MCS 12, 40MHz
270.0 Mbit/s, MCS 14, 40MHz
We can see everything goes fine and 40 MHz wide frequency rage is consumpted
At the same time, Ipad connect only at
24.0 Mbit/s, MCS 0, 20MHz
104.0 Mbit/s, MCS 13, 20MHz
And Iphone 5 - even worse - at
24.0 Mbit/s, MCS 0, 20MHz
52.0 Mbit/s, MCS 5, 20MHz
I looked a lot of discussions but I can not figure out what to do, to make my Iphone work fgaster than 65Mbits and Ipads - faster than 130Mbits... It is a maximum in my conditions and I dunno what to fix...Hi deemona,
Everything appears to be normal on your wireless network. It all comes down to what WiFi standards each device supports. On 2.4GHz the iPhone 5 only supports a max of 72Mpbs (20MHz, 1 stream). The new iPad (mini/Air) supports a max of 150Mbps (20Mhz, 2 streams).
On 5GHz things change slightly where both the iPhone 5 and new iPads support 40Mhz channel bonding allowing each to support higher speeds, the iPhone 5 150Mbps and new iPads 300Mbps.
Hope this helps!

WLAN API is misreporting 802.11ac channel widths
I'm working with a high density Aruba Networks wifi deployment. To avoid co-channel interference, I've dialed my channel widths back to 20MHz only. I've confirmed the config with the vendor and written up the results of what I've found on my blog (if you want better detail) http://wi-infi.blogspot.com. I'm connecting to an Aruba 225 access point and getting an 802.11ac connection on channel 149, but the wifi tools on the mac are reporting the channel width at 40MHz.
I'm using a late 2013 MacBook Pro Retina 13 with OSX 10.10.2.
An option click on the wifi icon shows Channel 149 (5 GHz, 40 Mhz), PHY mode is 802.11ac, and an airport -I command lists the same with a lastTXRate of 174 and an MCS of 8.
I do know that the beacon frame from the AP reports 20MHz only, but it is still also reporting a secondary channel above the first. I don't think it's supposed to do this as it is unused, but it may still be there because VHT is still enabled on the 20MHz channels.
This results in a problem because many of the wifi utilities use the CoreWLAN API in OSX to report what they're seeing and it's incorrect.
I also have a suspicion that this may be related, at least loosely, to the problems I'm having with MacBooks having trouble maintaining wifi connectivity.There are other adapters out there that are 3x3 in which I have tested also. It really depends on the driver to be honest. Even on a 3x3, the card connection speed shows the same as your and that is max I have ever seen. Now the actual througout is a different story. What your connected at doesn't mean that your throughput is that great. Yeah it's better than 802.11n, but you really need a clean environment and you also have to be close enough to achieve the high rates of AC. Here is a list of AC products for reference:

Hi:
Is it possible to connect two WRT160N routers wirelessly with each other?
I would like to expand the range and performance of my network including internet.
I currently have WRT54G and WAP54G. Based on the multiple user reviews of the WAP4400N I am against buying it.
Can you please explain what is Cascading and Bridging. If you have other suggestions please advise. If not, I'll have to wait unitl Linksys releases a reliable WAP-N (wish I knew how long that would take)..
Thanks,
MitkaIts not possible to connect 2 WRT160N routers wirelessly with each other.You could the WAP300N with the WRT160N router which will work fine provided you setup the wireless wide channel to 20 - MHZ channel & Standard channel being 11.Also, you do the wireless & advanced wireless settings on router...
Difference between Cascading & Bridging..
Cascading is using 2 routers either wired or wireless one after another...ie., NAT behind NAT.
Bridging is wat you use 2 topologies ie., you use WRT54G & WET54G to convert the wireless signal into wired use the switch in between & send it to no of computers. -
Anyone get a 300 Mbit link speed using 40 MHz (Channel-Bonding) on 802.11n?
I recently switched from a MacBook Pro 2.33 C2D 15 to a new MacBook Air 1.86 SSD... For some reason, one little persistent mystery that remains, is that I have been unable to get the Air to establish the link speed at 300 Mbit/s at 40 Mhz (Channel-Bonded). The best I can get is 270 Mbit/s, although my MacBook Pro consistently links at maximum. Signal quality is not an issue...
Anyone have an idea why? Can an Air owner out there confirm max link, or is this little gem incapable of 802.11n wide 300 Mbit/s?
Thanks to anyone who can shed light on this little puzzle...Thanks for the reply.
First, you need your TC's 'Radio Mode' set to '802.11n only (5 Ghz)' - (I assume you do, since I don't think the 'Use wide channels' option should appear in any other mode...).
Now, the quick method to check Link Speed is in the 'Network Utility' Info tab...
Note that I don't have a major issue with my transfer rates, but do think it's an anomaly for a MacBook Pro to consistently link at 300 Mbit/s and my Air to refuse the same (max 270). In general, I would say that my Air exhibits (a bit) less sensitivity than the Pro with consistent wireless performance (i.e., I never had issues with the Pro acquiring and maintaining wireless links - the Air less so...).
Thanks for your help. -
Wrt320N channel width question for g & n devices
Hello guys,
Just bought a new Wrt320N router and I have played around with various settings checking each channel for better signals & etc. i even adjusted the recommended variables under advanced wireless settings as suggested on this forum.
Current setup is this, currently I have several iphones, wireless macbook, and a ps3(all wireless g devices) and my main computer is a imac with n capabilities along with a soon to arrive linksys WET610N Wireless-N Bridge for the ps3. I have found that the settings under basic wirelss work best set to:
mixed
I named my SSID
channel width to 20Mhz
channel on 1
As soon as I select auto which supposedly is better with n devices I lose signal strenght and speed? Can I leave this setting on 20Mhz even though it recommends auto for setups with n devices?
Thanks,
BrandonChannels are important to understand because they affect the overall capacity of your WLAN. A channel represents a narrow band of radio frequency. Since radio frequency modulates within a band of frequencies, there is a limited amount of bandwidth within any given range to carry data. Therefore it is important that the frequencies do not overlap or else the throughput would be significantly lowered as the network sorts and reassembles the data packets sent over the air.
Each channel is capable of carrying the maximum throughput for its standard.Try changing your wireless router's channel through your router's configuration page to see if your signal strength improves. You don't need to change your computer's configuration, because it'll automatically detect the new channel.
When you keep the Radio Band as Standard Channel 20MHz...Try changing the Standard Channel to 6,9 or 11 and check the through output.Also,If all your wireless devices are of N standard then,under the Advance Wireless Settings,Change the N Transmission rate to 15-130Mbps. -
Where is the channel width setting?
I'm trying to optimize my Airport settings for a wide range of devices and learned from this Apple Support Article about "Channel Width."
http://support.apple.com/kb/HT4199
It's frustrating to see such references in these articles yet find no corresponding setting in Airport Utility. We have a fourth generation TC and the article was written in Nov, 2011, so they should correspond. Our AU version is 5.5.3 and there are no available updates from within AU or through general Software Update. Could there be a firmware update not available through these channels? I'd appreciate any help solving this little mystery.The guide line..
Recommended settings for Wi-Fi routers and access points
Is to cover all brands of routers and indeed correspond exactly to what Apple preset their own products.
Apple is biased in certain areas and other manufacturers do allow other settings than Apple recommends. Wireless in some ways is yet an infant technology still ruled by much voodoo and need to offer suitable numbers of chicken livers to the gods of ether.. and even with Apple products where so many controls are hidden or non-existent.. it doesn't always work as it should. We are on the way to wireless nirvana!! IMHO the journey is endless. No sooner will a solution be found to a problem than a new one will crop up. If it works as it generally does.. without wires.. be thankful. -
How to program a midi foot controller on Mainstage? Does anyone knows how to program the foot controller with exclusive solo channel in order not to dance "tip tap" while from clean guitar I go to crunch or solo? How to do this programming on Mainstage?
I basically managed to learn how to invert parameters which allows me to be as default in the clean guitar channel and if I switch the first button on the midi foot controller I switch to crunch, but at this point I tryied so hard to programm the second and third button to switch, only through a button in one step, to a third channel for distorsion or a 4th channel for solo guitar but I couldn't figured out how this work can be done!
I would appreciate if anyone could help or share this experience with others who are experiencing the same problem.
Cheers.
F.I cannot seem to get mainstage to recognize my FCB either. I am using IFCB. Anyone figure this out?
Thanks,

Hello!
I want to write 1 digital port from PXI-6536 with streaming to TDMS file.
I'm writing by 'DAQmx Configure Logging.vi' and become TDMS file with 8 boolean channels.
How can I write to 1integer channel?

1.JPG 27 KBHey Atrina,
The actual data stored on disk is just the raw data (that is, a byte per sample in your case). It's really just a matter of how that data is being represented in LabVIEW whenever you read back the TDMS file.
I'm not sure if there is a better way to do this, but here is a way to accomplish what you're wanting:
Read back the TDMS file as a digital waveform. Then there's a conversion function in LabVIEW called DWDT Digital to Binary. This function will convert that set of digital channels into the "port format" that you're wanting. I've attached an example of what I mean.
Note: When looking at this VI, there are a few things that the downgrade process did to the VI that I would not recommend for these TDMS files. It added a 1.0 constant on the TDMS Open function, and it set "disable buffering" on the TDMS Open function to false; you can get rid of both of those constants.
