Topic: Archer C7 5GHz radio0 is "disabled or not associated"

The content of this topic has been archived on 13 Apr 2018. There are no obvious gaps in this topic, but there may still be some posts missing at the end.

Hello,

I was successful in installing OpenWrt on the TP-Link Archer C7 v2 running OpenWrt Chaos Calmer 15.05.1 / LuCI 15.05-149-g0d8bbd2 Release (git-15.363.78009-956be55) kernel version 3.18.23.

When the router was not connected to the internet both wireless radios were active. Now I have connected the internet to it the 802.11ac radio0 5GHz radio has dropped off, even though it is "enabled" in the GUI it is shown as being "disabled or not associated".

Are there any diagonistics I can run on this? I am stuck

Here is

cat /var/run/hostapd-phy0.conf

hastebin.com/gavoxusela

cat /etc/config/wireless

hastebin.com/orasulofig

ubus call network.wireless status

hastebin.com/woxenelaxi

(My next step is of course to remove the internet connection and see the status of the radio then, however this is a busy shared home network where I can't keep resetting the network, plus the router is in another section of the house in a different apartment and the tenant has had enough with me coming in and out today so I have to try it tomorrow. It's just part of living in a shared home ^^)

Rather than screenshots, cut text out of your terminal window and paste it into your post with code tags.

iw dev


shows which wifi interfaces have been created.

iw list

shows the capabilities of your wifi radio(s) and driver.

Sure no problem and thanks for the message. But fyi I was using hastebin, which is just a pastebin, to prevent a wall of text.. I wasn't sure if it was frowned upon.

Alright so iw dev gives me
