If this option is enabled, wireless clients or devices will not be able to communicate with each other but will be able to communicate with the gateway. (This may be useful for guest networks)

• Default * (default)
• 1-2 Mbps
• All

Depending on the wireless mode you have selected, a default set of supported data rates will be selected. The default setting will ensure maximum compatibility with all devices.

Specify the period of time between one beacon and the next one. A beacon is a packet broadcast by the router to synchronize the wireless network.

Default value: 100 ms

Options:

• Disable * (default)

The country-specific regulatory domains also incorporate mechanisms for detecting other services that have priority use of the bands shared with wireless lan, such as aircraft radar. Recommendation / Default is Off

Country code AND rev define the possible channel list, power and other regulations. The current wireless driver (year 2020) supports round about ~290 countries and round about ~2000 combinations for country code and rev.

Country / Region and Country Rev EXAMPLES:

• CY / 4 - Country: CY (Cyprus) AND Country Rev: 4
• CZ / 4 - Country: CZ (Czech Republic) AND Country Rev: 4
• EU / 13 - Country: EU (Europe) AND Country Rev: 13
• EU / 33 - Country: EU (Europe) AND Country Rev: 33
• EU / 53 - Country: EU (Europe) AND Country Rev: 53
• EU / 78 - Country: EU (Europe) AND Country Rev: 78

Example: If the Tomato User wants to change the country to USA, please change country / region to “US” and country rev to “0”. (Default setup is “Singapore” and “12”. Changing only country to “US” and leave “12” WILL NOT WORK)

The advanced-wireless page does provide / show the above mentioned examples, so that most user will be able to choose the one they need/want. (There are much more, see the following list/commit)

For SDK6 router have a look at the following commit https://bitbucket.org/pedro311/freshtomato-arm/commits/ffb286c7afa64b02bc2136d6bd67ba6f7f6b42b2

On the right side (comment field) you will see the valid combination for country and country rev. You can also see here that country “US” and country rev “12” is NOT a valid setting for the wireless driver. The same can be done (or looked up) for any other country, like Europe (EU), Germany (DE), …

Note: please choose a real country and not “#a” or “#r”. They are for debugging/testing and not meant for daily use.

Further Notes: For Tomato MIPS SDK5 (RT and RT-N) we only have a country selection right now. Starting with MIPS SDK6 (RT-AC) and all ARM-Branches/Versions you have to choose a country and a country rev. This applies to FreshTomato 2020-6 and up.

see above. This GUI setting applies to FreshTomato 2020-6 and up.

Bluetooth and 2.4 GHz wireless radio can interfere with each other, both operate at the same band (2.4 GHz). This option can help to improve the situation. The bluetooth devices must also implement the coexistence functionality, otherwise this option will have no effect.

Adjust value

default: 0

Delivery traffic indication message (DTIM) is a countdown field notifying wireless clients of when they can expect the next window for listening to broadcast and multicast messages from the wireless router. This option is useful for associated clients configured to enter sleep mode as a DTIM message will notify the client that the wireless router has information that must be sent.

This option specifies the maximum size before data is fragmented into multiple packets. Too low values may result in poor network performance.

Recommendation: leave the default value of 2346

Override regulatory and other limitations; Use 0 for country default (this is the recommendation/default setting). This option can be used to lower or increase the output power. (For example: lower ouput power to decrease wireless range)

Options:

• Auto * (default)
• 1 Mbps
• … up to

• Non-WLAN
• WLAN Manual
• WLAN Auto
• WLAN Auto with Noise Reduction

Wireless Multimedia options:

• Auto

Enable 256-QAM (MCS 8/9) support. Wireless Mode must be set to Auto. Note: Not all router support that feature.

Router and wireless client both support beamforming technology. Allow these devices to communicate channel estimation and steering direction to each other to improve download and upload speed. Note: Not all router support that feature.

For Legacy wireless network adapter that do no support beamforming, the router estimates the channel and determines the steering direction to improve the downlink speed. (It is also called Implicit Beamforming) Note: Not all router support that feature.
