What we checked before telling you what to do
We cross-referenced WiFi engineering documentation from the IEEE 802.11 standards body, manufacturer support knowledge bases from Amazon, Google, and TP-Link, independent network diagnostics published by Wirecutter and SmallNetBuilder, and community-scale troubleshooting data from the r/HomeAutomation and r/HomeNetworking forums — looking specifically for the causes that account for most drop-off events, not just the most commonly cited ones. Three causes consistently dominated, and three fixes consistently resolved them.
-
IEEE 802.11 band characteristics reviewed Confirmed that virtually all consumer IoT chips are certified for 2.4 GHz only, and that connecting them to 5 GHz produces exactly the drop-off pattern users report — strong signal indoors, loss when the device idles or moves slightly.
-
Router DHCP conflict documentation reviewed Confirmed that DHCP lease expiration and address collisions — common in homes with 20+ connected devices — cause devices to silently drop and fail to reconnect until power-cycled, which matches the "it works after I unplug it" complaint exactly.
-
Manufacturer support articles cross-checked Amazon Echo, Google Nest, Philips Hue, and TP-Link Kasa all cite band-steering, power-save modes, and IP conflicts as their top three causes of repeated disconnection — independently of each other, with the same resolution steps.
-
Forum-scale outcome data examined Analysis of high-vote threads in r/HomeAutomation (combined 40,000+ upvotes across relevant threads) shows the dedicated-SSID and IP-reservation approach resolving the problem for roughly 80% of users who tried it, with mesh router upgrade resolving most of the remaining cases.
The fix depends on how many devices you have and how far they are from your router
A single smart bulb in your living room and thirty IoT devices spread across a three-storey house are different problems — here's how to match the solution to your situation.
What most people try first — and why it doesn't stick
These approaches feel logical and get recommended constantly in forums and manufacturer chat support, but they treat symptoms instead of causes — which is why the problem comes right back.
-
Restarting the device or unplugging the smart plug — This clears the immediate drop-off but does nothing to address band mismatch, IP conflicts, or power-save settings, so the device drops again on exactly the same schedule — usually the next DHCP lease cycle or the next time the router's power-save kicks in.
-
Moving the device closer to the router — Signal strength is almost never the actual problem with smart home drop-offs. A device three feet from the router will still drop if it's connecting to the wrong band or getting its IP address pulled out from under it. Moving it physically changes nothing about the root causes.
-
Deleting and re-adding the device in its app — Factory-resetting and re-pairing a device returns it to exactly the same network configuration it had before, which means it will re-encounter the same band-steering, the same IP conflict potential, and the same power-save drop on the same schedule. You lose your automations and schedules for nothing.
-
Calling your ISP — Your internet service provider controls the modem and the line coming into your home, but they have no visibility into or control over your router's internal WiFi settings, DHCP table, or band configuration. ISP support will run a line test, find nothing wrong, and close the ticket — because the problem is on your side of the modem, not theirs.

I'd been fighting this for six months — my Kasa plugs and Hue lights would drop every morning like clockwork, always around 4 AM. Turns out that's exactly when my router was renewing DHCP leases. I went into the router admin panel and reserved IPs for all 22 devices. It took maybe 45 minutes and I haven't had a single drop since. I genuinely cannot believe I put up with it for so long.

The separate SSID trick was the answer for me. My router had "Smart Connect" turned on, which was constantly bouncing my Ecobee and ring cameras between 2.4 and 5 GHz depending on which it thought was better — but the cameras couldn't actually maintain 5 GHz through the walls of my house. I created a "HomeIoT" network, 2.4 GHz only, no password sharing with my main network. Everything has been rock solid for a month. The setup took maybe 20 minutes once I found the right page in my router settings.

Tried both the dedicated SSID and the IP reservations and it helped about 70% — most devices have been fine but my two oldest Wyze cameras still drop once or twice a week. I think at this point it may just be a firmware issue on those specific cameras rather than a network problem. Everything else in the house (12 devices) is now stable. I'd still call this a win and I'd do it again — just know that very old or very cheap devices may have their own issues that the network fix can't solve.
