Wide channel bonding?

I recently upgraded my home network from a G router to a draftN router. However I have not noticed any increase in speed.
It's connected on channel 1 (2.4ghz)
But the transmit rate is 73 and the MCS index is 7.
So my buddy who has a Dell laptop with Win7 comes over and he shows me that my router is on 20mhz channel width. He changes that to 20/40. Then in Windows on his Dell he goes into the properties of the network connection configuration and changes a similar setting in there.  Now he is showing speeds of 150mbps. He says that this setting has to be switched on all Windows computers. And if I did that on my Macbook Pro then I would see my 73mbps increase to 150 just like his.
Is there a way to force my MBP to "see" and use the 40mhz width?

I realize I am never going to get 300mbps from this draftN router (it's a Tenda for what that's worth) but Network Util is reporting 72mbps which is nowhere close to numbers I've been seeing on other posts like 130, 150, and even 270.
As for returning it, I don't think so. I got it on sale. Was really marked down. Now I see the price of cheap technology.

  • How to tell if client is channel bonding from WLC end?

    Greetings,
    I'm reading that if the WLC client detail shows rates m7 - m15, then it must be a 40Mhz wide channel (bonded 20's). However, I'm seeing those rates on 2.4 clients as well, which would be impossible, since those are not bonded.   I'm looking at a 4402 running 7.0.240.0.
    Is the 2.4 reading just buggy?  Different rules for 2.4 MCS?  Why doesn't Cisco simply show the Mbps like the client itself does rather than leaving us with this MCS mXX hieroglyph? :-)
    Thanks!
    Gary

    So long as the rate is avaialber and the client has RSSI/SNR to support it, it can connect at that rate.  There are diffferent rates for 20 vs 40 wide, as well as the guard interval.

  • 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.

  • Using Wide Channel in draft-n routers

    Hi all,
    I've recently purchased the WRT310N router together with a WPC600N PCMCIA card for use in my notebook.  I have other 802.11G devices at home (a SqueezeBox, another notebook with built-in G adapter and a BlackBerry Bold) which connect to the new router as well.  Over the last 2 weeks, my wireless network has been practically unusable, requiring resets every couple of hours or twice daily at best.  I've tried most of the recommendations from this forum - hard-resets; changing parameters like beacon interval etc..; changing to different channels (wide & standard), none of this really helped.
    I then researched on the 802.11n standard and I think the firmware from Linksys seems to have some fundamental problem on the "wide channel" option.  From various sources on the web, the "channel bonding" feature of 802.11n will utilise two ADJACENT and NON-OVERLAPPING 20MHz channels together to increase the overall bandwidth.  As we all know, in the 2.4GHz band, if we start from channel 1, there could only be 3 non-overlapping channels altogether - CH1, CH6 and CH11.  However, in the firmware of my WRT310N, if I choose CH6 as the wide channel, I'd be given the choice of either CH4 or CH8 as the standard channel.  As each channel will need 20MHz but is only 5MHz apart from the adjacent channel, both CH4 or CH8 will directly interfere with CH6, causing unstable transmission/reception.  I believe what the firmware should do when you choose CH6 as the wide channel is to give you only CH1 or CH11 as the standard channel.
    With the above in mind, I disabled the wide channel option totally, my WPC600N now runs at a much lower bandwidth but the stability for my whole network has improved a lot (I haven't had a reboot since the last 24 hrs).  Can someone confirm if my theory above is correct or not?
    Regards,
    Paul.

  • Airport Extreme Channel Bonding

    Does anyone know if the Airport Extreme Base Station (802.11n) supports channel bonding. Channel bonding of course is setting both the base station and the airport card in the computer to use 2 of the 11 channels instead of just 1 in order to achieve a full 300Mbs data rate.
    And I'm not talking about the setting for combined b/g/n operation, that's something different...
    Thanks,
    -Chris

    The AirPorts only support "channel bonding" on the 5 GHz radio when the "Use wide channels" option is enabled. They do not support a similar feature for the 2.4 GHz radio.

  • Linksys E4200 is not channel bonding

    I have been trying for weeks to figure out why my linksys E4200 would not do 300 mbps I think I came up with the answer the firmware is not allowing it to channel bond on the 2.4ghz channel  in my old 160n when I change the channel width to 20 to 40mhz it shows 40mhz only in the status of the router in the E4200 it shows 20mhz only is this a firmware problem and how do you inform linksys of it there tech support is pretty much useless.

    dkjohn - sorry I do not have an answer.  I started a similar thread yesterday titled E4200 2.4G 40mhz bandwidth issues, no responses yet.  I can get channel bonding using channel 6, or auto which gives me channel 6, no other channels will bond.  When bonded the channels are 6 & 2.  Unfortunately after 4 minutes of either laptop being booted up, The router drops from 40 mhz to 20 mhz and the channels report 6 & 0.  If I have no wireless PC's on the router will stay at 40 mhz and channels 6 & 2 "forever".  Not sure if this is firmware or a defective router.

  • Channel Bonding? Oracle RAC with multiple redundant network

    We are planning on setting up on Oracle RAC 10g on Linux.
    We have redundant switches, so I would like to set up the network to have some version of network redundancy.
    Under windows, it is called 'teaming'. Linux is 'channel-bonding'
    I just want to make sure if I setup the channel-bonded interfaces, it will be supported with RAC. Has anyone done this before??
    -Andy

    we are running our RAC on NIC bonding. Although we need to do some more testing to be real sure as to the functionality of the bond.
    Metalink Note:298891.1 would be a good place to start.

  • Is anyone using a 1252 ap in bridge mode with channel bonding?

    Is anyone using a 1252 ap in bridge mode, with channel bonding?
    I had a question a while ago from a customer with regards to bridging with a 1252 ap to increase throughput for a wireless link he was using, from the throughput improvements in 802.11n. At the time I spoke to Cisco Pre-Sales, and they indicated that the bridge function in the 1252 exists for 'testing' purposes. I advised our customer that although it should be possible to implement, we may run into difficulties with TAC support ect. in the event of problems with the link.
    Can anyone comment if this is a Cisco validated/approved design now?
    Also, has anyone done this and tested the throughput achievable?
    Has anyone bridged both 2.4Ghz and 5Ghz radios on a 1252?
    The reason I ask is I've seen a note about a Cisco 5Ghz 802.11n bridge being launched.
    Thanks in advance.
    Alex.

    Hi All,
    Thanks for all the feedback; I have finally done some throughput testing with the 1252's. Please note, this is very rough, just to give an idea on throughput that's achievable, and what you can enable. Did this a few weeks back, and have now wiped the cnf, so dont have the show runs any more....
    The two devices were set up a few feet apart, with the standard 2dBi and 3dBi antenna.
    All tests done on the 5GHz radio with Autonomous AP IOS.
    I did data transfers via a laptop either end of the link; transferring data using the Test TCP utility (wasn't going for scientific tests, just getting some idea of throughput).
    802.11a @ 54mbs (20Mhz chan) WGB - root to non root = 2.43 - 2.5MB/Sec = 19.44 - 20 Mbps
    802.11a @ 54mbs (20Mhz chan) WGB non root to root = 2.42 - 2.44MB/Sec = 19.44 - 20 Mbps
    802.11n @ 'n' rates( 20Mhz chan) WGB root to non root = 6.18 - 6.33MB/Sec = 49.44 - 50.64 Mbps
    802.11n @ 'n' rates ( 20Mhz chan) WGB non root to root = 4.77 - 5.00MB/Sec = 38.16 - 40 Mbps
    802.11n @ 'n' rates ( 40Mhz chan) WGB root to non root = 8.59 - 8.58MB/Sec = 68.64 - 68.64 Mbps
    802.11n @ 'n' rates ( 40Mhz chan) WGB non root to root = 6.35 - 7.20MB/Sec = 50.8 - 57.6 Mbps
    802.11n @ 'n' rates ( 40Mhz chan) Bridge root to non root = 9.73 - 10MB/Sec = 77.84 - 80 Mbps
    802.11n @ 'n' rates ( 40Mhz chan) Bridge non root to root = 8.40 - 8.57MB/Sec = 67.2 - 68.56 Mbps
    So basically, as per the above posts, you can implement bridging on the 1252's and utilise the 802.11n rates and features, SGI, Spatial Streams and Channel Bonding etc, to achieve higher throughput.
    Also, as per the above posts, this is still not supported by Cisco, so, in my case, I'd be highlighting that to customers straight off, but don't see it as too much of an impediment to deploy, as long as the customer weighs up the risks.
    On a side note, I attended a Cisco session recently, and was told that the 802.11n Bridge, (the 1430?) was on hold indefinitely. My feeling is that this makes it more pressing that Cisco introduces support for bridging on the 1252.
    Get in the ear of your local Wireless SE's, the more they hear it, the more they'll moan to the Wireless BU in San Jose! ;-)
    Bridging with 802.11n has some interesting possibilities, I worked with Alvarion 5GHz bridges 6 or 7 years ago, that could do 'near LOS' - Worked well in cities, using reflection of the RF from buildings. I had never heard of 802.11n back then, but I'm guessing Alvarion was using MIMO to achieve good non-LOS connectivity in the 5GHz band.
    Cheers,
    Alex.

  • How many 80Mhz wide channels?

    I am getting ready to install some 3700 series AP's and then also configure the WLAN controller to support 802.11ac.  I was reading on the net that there are basically 5 80Mhz channels you can use however when I look over Cisco documentation I do not see any reference to this and only see a DCA listing that would allow only 3 80Mhz wide channels.  Here is the document I mentioned. - http://www.cisco.com/c/en/us/td/docs/wireless/technology/5760_deploy/CT5760_Controller_Deployment_Guide/802_11ac_support_on_WLC5760_and_Catalyst_3850.html
    Here are the channel groupings for 5 channels that I want to setup:
    36-48
    52-64
    100-112
    132-149
    153-165
    Am I missing something or will this work? 
    Seth

    80 MHz wide channels allow for five (5) non-overlapping channels in the U.S. and five (5) in the UK/EU (channels 149 and higher require light licensing for outdoor use only) when DFS is used, but only two (2) channels in the U.S. and one (1) in UK/EU without DFS.

  • Wide Channels in Australia and New Zealand

    Although I could connect my Macbook Pro C2D to the Airport Extreme (n) using 5GHz n-only, it refused to connect (" There was an error...") if Use Wide Channels was selected.
    I tried changing the country from NZ to Australia and it then worked (link speed 300). Yet as far as I know, the two countries have the same regulations, and NZ is not listed as banning wide channels - and the option was available with NZ set, it just didn't connect.
    So is this a bug? Or do Apple know something I don't?

  • N 5GHz wide channel wireless extension low throughput, why?

    I have 1 Time Capsule and 1 Airport Extreme, both in different to rooms to extend my internet connection across my flat without any cables.
    The capsule creates a N-only 5Ghz wide channel network and is connected to a DSL modem in my office room.
    The extreme extends that network into the living room, also using wide channel.
    For testing I have wired a Mac to the extreme.
    When I access from that Mac the capsule disk (so exercising the wireless link between extreme and capsule) I get at most 3.7MBytes/s.
    When connecting wirelessly to the extreme it is even worse: 2MBytes/s.
    For comparison:
    When I wire the Mac directly to the Capsule (so excluding the extreme from the wexperiment) I get about 16MBytes/s.
    When connecting wirelessly to the capsule (also exclding the extreme) I get about 9MBytes/s.
    It seems that the two base stations do not talk N to each other (and I did not use WDS!). Am I missing the point here? Shouldn't the wireless link between s the N base stations be more than lousy 3.7MBytes/s?
    How come?
    I'd love to fix this!

    William your asnwer sound somewhat standard. We know that WDS halves throughput. We know we can use "extend network" in N networks.
    That is exactly why we do that Again: I do not use WDS here (in case I haven't mentioned it explicitely).
    I use the N network extension feature and still get these lousy rates.
    Could it be that the working principle of WDS and N network extension is very similar?
    Does anyone know how both work and what the real difference is? (Except for WDS being for G networks We know that aready.
    Another thing:
    The antennas in Airport extreme and TC don't seem to be too good: Lifting the station half a meter from the floor up to a table makes a difference of several hundred Bytes/s!

  • No "wide channel" connected with wusb300n to wrt350n router!

    Ok - just to make sure Apple hears about every one of us having the problem. I never had any issues with my wireless connection prior to the 2.01 upgrade but now streaming from my Mac to the AppleTV using the Airtunes function doesn't work for more than 5-10min before the network connection is dropped.
    Configuration:
    - AEBS running a N only 5GHz network and using Wide Channels - latest software & firmware
    - AppleTV with 2.01 software
    - iMac used for streaming
    I'm not planning to switch 2.4Ghz or stop using wide channels (I already have a 2.4Ghz G network thank you )- so please Apple we need a patch!
    Kind regards

  • Channel bonding

    Hi,
    Need some advise here. My faculty of architecture decided to go all wireless this year. I've design the wireless network with a high density of 5Ghz APs. When a look at the stats, I dont have any legacy 802.11a device. Since I have a lot of user cramped in a small building and they need to send very large file, does it make more sense to use 20Mhz or 40Mhz channel. Right now, with 20 Mhz channel, I dont overlap but with 40...I've sure there will be some in the most cramped area. Advice....
    Typical use a the network is sending CAD files(building plans) of 100MB to 500MB. Many one file directly from NFS servers...some could say that wireless is no good for this type of usage...but try gaining the authorisation to put wall jack in a historic building built in 1670.   

    Hello Dominic,
    The question to bond or not to bond, that is the real question. And my advice, BOND.
    The 5 GHz side allows for many more channelsm even with hi density you can still design a network with limited over coverage. Lets look at the basic UNIIs.
    UNII 1 - 4 channel
    UNII 2 - 4 channel
    UNII 3 - 4 channels
    Just using the basic UNIIs you have a total of 6 channels to deisgn with, thats double what we have on the 2.4 GHz side. A few things you might know already, but will cover for good measure.
    When you bond and take advantage of 802.11n rates you need to insure WMM is supported on the WLAN. You also need to use WPA2/AES. If you dont meet these 2 items, no 802.11n for you.
    When 2 channels are bonded, 1 channel will act as your managment, meaning this is where your beacons will come out of. This allows legacy devices (802.11a) to see and use the medium if they dont support 802.11n 40 MHz.
    Only problem I would be aware of, based on my expereince. Is neigboring access points that may also be bonding and causing you interference.
    I hope this helps ..

  • [Cisco FAQ] - What is DOCSIS 3.0 Upstream Channel Bonding?

    describe what it does.

    DOCSIS 3.0 required that CM must have 4 or more upstream channel transmitters. This translates into the
    possibility of 100mbps+ upstream rate…
    Removed DOCSIS 2.0/1.x single request-grant cycle bottleneck.
    Bonded Flows allow multiple outstanding BW-REQ.
    BW can be requested on any of the bonded upstream channels
    Requests can be granted on any of the bonded upstream channels
    Reduced upstream latency (TCP ACK) also increases DS throughput. [TCP application]
    Bonds multiple, physical upstream transmit channels to form a larger, logical upstream channel.
