I had a working router/wifi. I installed the correct sysupgrade.bin, but after this, my tablet, smartphones and windows based laptops cannot access wifi.
Here is the firmware that worked:
OpenWrt SNAPSHOT r7066-060e1ecefa / LuCI Master (git-18.151.24607-5452cc2)
Kernel Version 4.9.102
on a TP-Link Archer C7 v2 Qualcomm Atheros QCA9558 ver 1 rev 0
How do I revert back to this? Yes I made a backup.
How do I determine whether I need to regenerate the /etc/config/wireless? And where is a tutorial on doing this? I don't recall changing the wifi settings after the upgrade, only turning encryption on. Encryption on the sysupgrade was off by default. Is that the default setting?
The default setting is to disable both of the wifi radios so there is no wireless. If you're using LuCI you have to click the enable buttons near the top of the first network--wireless page.
This is very confusing. After the sysugrade allowed me into the LuCI webgui with user/pw, today, it would not. I had to ssh, update and install and even had to re-install LuCI. Very frustrating this info isn't better organized at the sysupgrade.bin pages.
ulmwind. Thank you. I got it working with a firstboot && reboot and reinstallation of luci as well as it's dependencies. As this became a "new" install, the wifi was off and unsecured. That is fixed. And this is all. Out.
