First let me say I have had the E20 for several weeks and it has been running great including the WiFi connection via my iPhone 6S. My modem died a few days ago and I replaced it with an Arris SBG8300. Since then I have not been able to get the E20 to connect to the net. I have followed the instructions and my phone links up to the E20 via the app. I get an check on Device connected and Message sent to device, however, I am timing out on the Connecting to the network. I insure outstanding signal I have the phone, Router/wifi and E20 side by side. Does anyone have any suggestions? The 2.4 side of the wifi is configured as follows:
Wireless Network: Enabled
Network Name (SSID):
Mode: 802.11 n802.11 g/n802.11 b/g/n
Security Mode: WPA2-PSK (AES) (Recommended)
Network Password:
Broadcast Network Name (SSID): Enabled
Enable WMM: Enabled
We are sorry for the trouble you are facing.
May i suggest you contact support via email : support@roborock.com to get a solution sooner?
You may need to force your wifi to 2.4 GHz to allow the robot to connect to it. On my router app there is a function specifically for this, it will disable 5GHz for 30 minutes. Check your router manual for something similar.
