@ NRatner,
As long as Almond is receiving the continuous/uninterrupted signals from the main router, it should be working fine. However, the following instructions would assist you in getting the internet connection on the Almond, so that we can update the software directly through touch screen which should also assist you in resolving the issue.
1) Connect an ethernet cable from one of the main router LAN ports to the Almond's WAN port (Gray port). Tap on "Status" on the Almond's touchscreen and it should shows the status as connected with green box, if not then you have to run the wizard on Almond in Router mode. Now, tap on "More" on the Almond's touchscreen, tap on "Software Update" and follow the instructions.
2) After the Almond reboots, turn off the main router, wait for 30 secs, turn it on and wait for all the lights to lit up.
3) Now, reset the Almond to factory default settings. To do so, press and hold the reset button (just above the power plug) for 10 seconds and release it.
4) Almond would restart, configure it in Range Extender mode, check it's performance and let us know the status.
