For anyone experiencing issues with WiFi after upgrading, it's likely that your Omega still has the configuration and wifi programs from the previous firmware, but is now running the new driver (which is not compatible with the old configs).
If you're in this situation, I would recommend to back-up anything you don't want to lose from the Omega to a USB and perform a factory reset. The same effect can be achieved with @michael-bourque 's method above
Also, we've been investigating some of the open issues with WiFi and have made more fixes.
Here's the updated list:WPA2 AES works AES+TKIP works TKIP works - connects within ~20 seconds as of b182 WPA (out-dated and should not be used) AES works - connects within ~20 seconds as of b182 AES+TKIP works - connects within ~20 seconds as of b182 TKIP works WEP (out-dated and should not be used) Shared Key Authentication works Open System Authentication does not work Open Networks (not secure and should not be used) Works as of b178 Kernel Module Installation
It is now possible to install additional kernel modules on your Omega but the following conditions must be met:Your Omega must be on the very latest available firmware If you're on b181 and b182 is available, the installation will not work The kernel modules must be from the Onion Package Repo (no kernel modules from the LEDE/OpenWRT package repos can be installed)
If there are kernel modules you would like to use that are not in our package repo, please let us know and we'll do our best to include them in a timely fashion.
