Hi @ZENER! I recommend trying this on a guest network, which should help to factor out any custom network settings. Please enable the guest network on your eero with a simple SSID and password, without special characters or spaces.
If this concern persists, try using ethernet connection, if possible. Our support team is also happy to assist with more in-depth troubleshooting if network connection cannot be obtained with your Base Station.
Forgive me if I'm out of line. Lily-white brand-new here, first post in fact.
I have experience with other IOT devices not connecting to WiFi. I've discovered that if WMM (WiFi Multimedia) is enabled on the router's 2.4GHz radio, IOT devices will not connect. Same problem possibly?
I'm not familiar with your router, so I've no idea if this is user-selectable in its firmware. My experience is with a Linksys WRT3200ACM, with OpenWRT firmware. YMMV.
I had this same problem and finally got it resolved. Two simple things to try in order of difficulty:
1. Unplug your router and any wireless devices. I have a mesh network, so I had four devices to unplug. Leave them off for 30 seconds or so and then plug back in. See if your base station will connect.
2. Unplug the base station and get a small scredriver to remove the battery cover on the back. Pull the battery which may be a little tricky, so be careful to not pull out the wires. Leave it off for about 30 seconds and then plug back in and replace the cover. Plug into power again and try to connect.
I've seen various reports of #1 working for people. I needed #2 which worked perfectly.
