I totally agree with ScottInNH and Analog, j0z0r , especially liked wjhat Skeltorr, mewse and fartface had to say. I would love to get superchannel on openwrt. I have almost mastered hostapd and I love what madwifi can do. I have integrated the best op borgbox into a 3.9 MB and 6.9 M firmware and added my own convienient scripts for mdk3 and ettercap. I build in my own multi virtual server freeradius and upgraded to the latest openssl. I had trouble reflashing a pico2HP to the 7M firmware (that previously used to work on the same device) after recompiling it to include my new and improved/corrected configs.
CTS Protection trigger 2; -default dd-wrt behavior A 802.11g client attempts to connect to a SSID that is using channel bonding. Transmissions using a 40 MHz channel in the presence of 802.11a or 802.11g clients require using CTS protection mode. This will apply the CTS protection mechanism on both 20 MHz halves of the 40 MHz channel, to prevent interference with legacy devices and allow proper operation of the 802.11a and 802.11g clients.
dd-wrt super channel activation keygens
according to this list 161 is supported at ht40 lower max and 157 for upper. the list shows the side channels with upper / lower channel setting. dd-wrt uses center channel as reference. 165 is completelly not possible at ht40 with stock firmware. its simply doing ht20 then.
iwlist is not useable for showing all frequencies if you enabled superchannel. iwlist has a total limit for shown elements. use "iw" tool for any information and it will find your channels. and seriously any bug report regarding to mobile phones are useless. i know alot of buggy android wifi drivers which are just causing issues because of bad powersave behaviours. mobile.and by the way. superchannel supports alot of frequencies which will not work on your client. so i just believe you dont know how to use the superchannel feature. done blame me for unsupported channels on your client.your iwlist info shows clearly that superchannel is enabled. otherwise you would see a 4 channel stepping.use superchannel only if your client does support superchannel. otherwise its bogus
i never use superchannel i dont know why you think i have it on superchannel is not enabled..& the router is not configured wrong, ant chains are both 1+2, ht40 only not dynamic, manual channel not auto, ack is 450, preamble is short, tried mixed & ng-mixed network mode, security is wpa2+aes. i do notice in dmesg output sometimes after using a channel thats broken like 149+upper, it would say its calling CRDA regulatory etc then says "unset", instead of "CA" if that means anything..23919 had working channels like the last 3 years but i guess theyre suddenly invalid channels now..& i said iphone was an example, ALL 1x1:1 clients wont connect on said broken channels, laptops & even other routers in client if i force 1x1 operation. but 2x2:2 will on some of the broken channels on 23919 everything every client is fine..i still think its some commit where ath9k was touched &/or the new start/stop but what do i know
i have not enabled superchannel i didnt buy any activation i dont need it, never have i ever used superchannel it is not activated. yes i agree its showing weird and wrong channels, but i have not turned on superchannel
reghack is the closest that I could find that is comparable to DD-WRT's super channels. A closer look at it, and I don't think that it enables the 2.3GHz band. However, it may still be useful for enabling it (perhaps requiring some patches or as a starting point.)
Embedded Atheros radio devices such as La Fonera, D-Link DIR-300home grade as well as Ubiquit Nanostaiton, and Bullet professional grade products all havefirmware running onboard Flash ram to control the radio chipset. Allyou do is go into the graphical user interface with your web browser and changethe country code (or enable the super channel for DD-WRT). (With homegrade Atheros routers such as the La Fonera, D-Link DIR-300, you will likelyneed to load third party firmware such as DD-WRT to be able to enable out ofband opperation. This is done via the web based firmware update box orusing TFTP)
After OpenWrt the best alternative free firmware for wifi routers is DD-WRT. It is also come under GNU license and gives you many extra additional features that never come with OEM firmware. DD-Wrt an interactive web interface loaded with excellent features such as a captive portal, OpenVPN, UNPN. After upgrading DDWRT you get the feature QoS to limit bandwidth for individual users and manage internet plans smartly. DD-WRT also gives your IPv4 and IPv6 protocol support with IP and Mac filtering feature to ensure network security. IF you are into telecom business or internet business you can turn your normal wifi router into a super-channel enabled device. DD-Wrt provides you with super-channel frequency to increase the performance and gives you a special frequency range.

CTS Protection trigger 1; - NON-default dd-wrt behaviorA client that wants to use the radio channel to send data packet(s) of a size that is equal or above the defined RTS threshold value.

The HART Protocol communicates at 1200 bps without interrupting the 4-20mA signal and allows a host application (master) to get two or more digital updates per second from a smart field device. As the digital FSK signal is phase continuous, there is no interference with the 4-20mA signal. The HART Protocol provides two simultaneous communication channels: the 4-20mA analog signal and a digital signal. The 4-20mA signal communicates the primary measured value (in the case of a field instrument) using the 4-20mA current loop - the fastest and most reliable industry standard. Additional device information is communicated using a digital signal that is superimposed on the analog signal. 2ff7e9595c
