Introduction:

This video looks at some of the OpenWrt wireless configuration settings. To be more specific, I am looking at the settings on the Linksys WRT1900ac (v1) though many of these core settings will be the same across multiple chipsets and routers. All the changes made in this tutorial are done via the command line (SSH) as I have found the settings in Luci to not really show meaningful information at times. For example, the channel value and the wireless mode value are frequently blank in Luci but are clearly configured in the /etc/config/wireless file.[/vc_column_text][/vc_column][/vc_row][vc_row type="in_container" scene_position="center" text_color="dark" text_align="left"][vc_column column_padding="no-extra-padding" column_padding_position="all" background_color_opacity="1" background_hover_color_opacity="1" width="1/1"][vc_gallery type="image_grid" images="1318,1316,1315" layout="3" gallery_style="1" img_size="300x300"][/vc_column][/vc_row][vc_row type="in_container" scene_position="center" text_color="dark" text_align="left"][vc_column column_padding="no-extra-padding" column_padding_position="all" background_color_opacity="1" background_hover_color_opacity="1" width="1/1"][vc_column_text]

Aims:

The main aim here is to get the router configured in the same modes as it would be with the native Linksys firmware out of the box. This means 600mbps b, g, n 2.4GHz wifi on the first radio and 1300mbps ac  5GHz wifi on the second radio. I also look at transmit power and how to make adjustments to that with a measurable change in output.

Conclusion:

Below is the wireless config I use for this router to get everything working great.config wifi-device 'radio0'option type 'mac80211'option channel '3'option hwmode '11g'option htmode 'VHT20'option path 'soc/soc:pcie-controller/pci0000:00/0000:00:02.0/0000:02:00.0'option disabled '1'option country 'GB'config wifi-ifaceoption device 'radio0'option network 'lan'option mode 'ap'option ssid 'YOURNETWORK'option encryption 'psk2'option key 'PASSWORD'config wifi-device 'radio1'option type 'mac80211'option hwmode '11a'option path 'soc/soc:pcie-controller/pci0000:00/0000:00:03.0/0000:03:00.0'option htmode 'VHT80'option disabled '0'option country 'GB'option channel '40'config wifi-ifaceoption device 'radio1'option network 'lan'option mode 'ap'option ssid 'YOURNETWORK'option encryption 'psk2'option key 'PASSWORD'The video is just a recording of me playing around with the wifi while looking at the changes live within inSSIDer.[/vc_column_text][/vc_column][/vc_row]
