What is fat channel intolerant?

Fat channel intolerant: When enabled, the client informs access points that it doesn’t support 40 MHz channel-widths in the 2.4 GHz band. 20/40 Coexistence: Enables coexistence techniques, which prevents the access point from using 40 MHz wide channels if it will interfere with any other detected networks.

How do I disable Fat channel intolerance?

In the Property: box, click 802.11n Mode and select Enabled from the drop-down menu under Value:. In the Property: box, click Fat Channel Intolerant and select Disabled from the drop-down menu under Value:. NOTE: You may need to uncheck the box next to Use default value to make any changes.

What WiFi mode is best?

If you want maximum throughput and minimal interference, channels 1, 6, and 11 are your best choices. But depending on other wireless networks in your vicinity, one of those channels might be a better option than the others.

Should I enable Xpress TM technology?

Broadcom’s Xpress Technology is one of the older performance-enhancing WiFi technologies, designed to improve wireless network efficiency and boost throughput. . It is not recommended to use Xpress in newer network environments (802.11n/ac), and with gaming, as any repackaging of data can introduce some delay.

Is Xpress technology good?

It is not only designed to improve network efficiency but also boost throughput speeds and is particularly successful in mixed environments. It is one of the early enhancement technologies designed for 802.11 but it was preceded by Intersil’s Prism Nitro and Atheros’ Super G.

Which wireless mode is best for gaming?

5GHz networks are more reliable than the older 2.4GHz band, but have a downside of a shorter range. Some older devices only support 2.4GHz Wi-Fi, but you can take advantage of 5GHz with newer devices, making a dual-band model vital. If you have to use Wi-Fi for gaming, use the 5GHz band if your system supports it.

Is 20MHz or 40MHz better?

A 20MHz channel width is wide enough to span one channel. . In crowded areas with a lot of frequency noise and interference, a single 20MHz channel will be more stable. 40MHz channel width allows for greater speed and faster transfer rates but it doesn’t perform as well in crowded areas.

What should my router settings be?

• 802.11 n Support. Enable: Faster speed by supporting N or later wifi tech. .
• WMM Settings. Enable: Many mobile devices like iphone and ipad need it to function. .
• 2.4 Ghz vs 5 Ghz. .
• 20 Mhz or 40 Mhz (And Best Wireless Channel) .
• AP Isolate. .
• IP Flood Detection. .
• Multicast Rate. .
• Preamble Type.

Which channel bandwidth should I use?

In most cases you should use 2.4 GHz to optimize for distance and 5 GHz to optimize for speed. However, there is a tradeoff between increased performance and range of coverage. 5 GHz is faster. 5 GHz Wi-Fi offers faster uploads and downloads than 2.4 GHz.

What wireless mode should I use for 2.4 GHz?

For the wireless mode, it is recommended to select B/G/N on the 2.4 GHz network. A/AC/N is recommended on the 5GHz network. This will allow all devices to connect to this network.

How do I change from 2.4 GHz to 5GHz?

1. Click on the WiFi icon in the bottom right corner of the task bar.
2. Then click on the network you want to use from the list of available networks.
3. Click Connect (type in the password and click Next if it’s your first time connecting to this network).

Should I disable ARP offload?

RECOMMENDATION: Keep this turned off. This offload is enables a feature where your computer responds to packets in sleep state. Unless you use that, there’s little reason to leave it on.

Should I enable 40MHz intolerant?

1 Answer. No, you shouldn’t disable that setting if any of your client devices use Bluetooth and sometimes need to use 2.4GHz Wi-Fi. What Netgear calls «20/40MHz coexistence» is probably just the required respect for the «40MHz intolerant» bit that some clients set.

What is the best channel for 2.4 Ghz?

The recommended channels to use on 2.4 Ghz are Channel 1, 6 & 11. As can be seen in the above diagram, these channels do not overlap into each other. In general 2.4 Ghz should be considered a legacy band for older devices that do not support 5 Ghz. It is often more crowded and less performant than 5 Ghz.

What is the best channel width for 2.4 GHz?

Set 2.4 GHz WiFi channel width to 20 MHz

So, if you were to choose a wider channel width that bonds multiple overlapping channels in this band, it is more likely than not that you will experience a weaker wireless performance than the expected faster speeds.

Should I enable 160 MHz router?

Best answer: To get as much speed as possible from your Wi-Fi 6 router, 160MHz is a must. For most homes, however, the speeds available at 80MHz are more than enough.

Does changing router channel increase speed?

Selecting the proper Wi-Fi channel can significantly improve your Wi-Fi coverage and performance. . Currently, many wireless routers automatically select the channel for you upon initial setup, where depending on your wireless environment, it could lead to slow Wi-Fi speeds and interference.

Forum

Does anyone know the technical details behind Intel’s 5100 AGN client device setting called «Fat Channel Intolerant» ?

Their website is poor on technical details. In brief, it says «it communicates to surrounding networks that the Wi-Fi adapter is not tolerant of 40 Mhz channels in the 2.4 GHz band». Elsewhere it mentions being incompatible with 802.11n — duh.

Is this merely the way of telling the adapter to only make 20 MHz connections, or is it some broadcast that tells nearby neighbors not to use it also ?

My guess is the former — but the opposite would be good to know about.

My understanding is setting that flag does both — tells the card not to use 40 MHz channels and also begs the neighbours not to use 40 MHz channels as well.

I say beg because I did some poking around on some Aruba gear at my place and it looks like ArubaOS is set to ‘Honor 40 MHz Intolerance’ by default but it is just a check box [url=http://www.flickr.com/photos/simplywifi/5798295274](see screenshot here)[/url] so anyone could simply decide not to honor that setting at any time. I can only assume other enterprise vendors have a similar toggle. Not sure about home gear though.

Seems like a good option for 2.4 GHz in theory, but if people can just turn it off I’m wondering how effective it really is.

In case anyone is interested, here is a screenshot showing the 40 MHz intolerance bit in Wireshark — [url=http://www.flickr.com/photos/simplywifi/5797819731](Intolerance bit not set)[/url]

WLANMAN, why wouldn’t an agn card be n capable? I just did a quick search on 5100AGN . looks like an old intel card that was designed during pre-n era. is that the one you’re referring to? Looks like 5300 is the newer card, post n ratification.

I agree with you both that it does seem like a smart option, to be able to request no 40 MHZ channels for 2.4. (Of course, why not just run 5GHZ and be done with it.) But «not allowing» doubled channels on the device itself at 2.4 almost seems useless to me; who would want to do that anyhow, and is INTEL just proecting people from themselves? =) But the idea of it being able to tell neighbors seems it might be useful. of course if I were running a 40 MHZ network and some yahoo card was able to bump me down to 20 I might be irritated. I am curious about exactly how this feature works now, what it specifically does. Thanks for the screen capture btw SimplyWiFi. Interesting that the bit’s set by default. I wonder if any of the SOHO devices address this option. Something more *sigh* to research! =) Good stuff!

Here’s the intel whitepaper I saw for INTEL’s cards: http://www.intel.com/products/wireless/adapters/5000/index.htm?wapkw=(5100)

Setting the «Fat Channel Intolerant» and at the same time allowing your own device to allow 40MHZ is what would be incompatible. Which Intel seems to agree with.

It would definitely not be «playing nice» to run 40MHz yourself, and not let your neighbors to do the same.

If you are running 40 MHZ channels in a sea of 2.4 GHZ 20 MHz channels you’re definitely being a bandwidth «road hog» — that is, if you are not following the rules.

I live in an area where several people are running «pre-n» AP’s. In this case Belkin. They defineitely don’t «play nice», and stomp all over everyone elses 20MHz wide comms. They don’t seem to care what is going on around them.
