Title: Google Home devices disconnecting from Wi-Fi overnight
Post by: kiliffe on June 11, 2019, 09:04:47 AM

I installed my new DIR-882 router last week, replacing an Asus AC-66U. I made no configuration changes to the default setup.

Environment: I am connected to Xfinity internet via my ARRIS SURFboard SB8200 DOCSIS 3.1 Cable Modem. My internet connection is very stable, experiencing very few, if any, outages.

Devices: I have three Sonos speakers running on wireless, five Google Home devices on wireless - a Nest Hub, a Home, and three Home Minis. I also have ten TP-Link Kasa wifi lightbulbs, and a number of other wired and wireless devices. I had no random disconnects from any of the devices since installing the Asus in September 2012.

Issue: In the few days now with the DIR-882, the Google Home devices ONLY have been disconnecting from the wifi overnight, every night. All other devices remain connected. That said, I have experienced a few times now that my Google Pixel 3 XL will not automatically connect to wifi when entering my home. I suspect that the Google Home issues have something to do with Smart Connect, so am considering configuring the 2.4 and 5 GHz radios independently and seeing if that works. However, that seems drastic, and effectively disables one of the most important features that led me to buying this router in replacing my Asus. What else should I try first before doing this? Thanks in advance.

EDIT: my Google Pixel 3 XL never reconnects to wifi when re-entering my home. It takes a power cycle of the router, and then magically my phone and Google a home devices automagically reconnect all by themselves.

• Ensure the default (dlink) SSID name is changed. Ensure that different SSID names are used between each WiFi 2.4/5Ghz radios. Can be anything and not something that's already in use by any neighbouring WiFi routers. Under Setup/Wireless/Manual.
• For routers with Smart Connect Technology (http://forums.dlink.com/index.php?topic=62072.0) , try disabling this feature and test. Under Wireless.
• What wireless modes are you using?
• 2.4Ghz and 5Ghz routers: Try single mode G or N or mixed G and N on 2.4Ghz and single mode N or AC on 5Ghz?
• Channel Width set for Auto 20/40Mhz or try 20Mhz only.
• Try setting a manual Channel (http://en.wikipedia.org/wiki/Wireless_channels) to a open or unused channel. 1, 6 or 11. 11 for single mode N if the channel is clear. 13 for EU regions. Try channel 48 or 149 on 5Ghz.
• What security mode are you using? Preferred security is WPA-Personal. WPA2/AES Only. Some WiFi adapters don't support AES (http://en.wikipedia.org/wiki/Advanced_Encryption_Standard), so you might want to try TPIK (http://en.wikipedia.org/wiki/Temporal_Key_Integrity_Protocol) only or Auto TPIK and AES.
• What wireless devices do you have connected?
• Ensure any devices with WiFi adapter drivers are updated.
• Any 2.4Ghz or 5Ghz cordless house phones or WiFi APs near by that maybe causing interferences?
• Any other WiFi routers in the area that maybe causing interferences? Link> Use a WiFi Scanner (http://forums.dlink.com/index.php?topic=48327.0) to find out. How many?

Router Placement
Forum User - "Well I feel really dumb. After moving the router away from other electronic devices my speeds are back to normal. Just a heads up for anyone experiencing slow speeds, you might want to move it away from other electronics and see if that helps."
3-6' feet minimum safe distance between devices.
Placement on main level floor and central in the building and WELL ventilated is preferred. Not in basements or closets as building materials, or near by electronics devices could interfere or hinder good signal propagation.
