WiFi disappears from two distinct routers.
WiFi disappears from two distinct routers.
My Wi-Fi keeps disconnecting and I'm puzzled about the cause. I switched two different routers, but there are no other devices nearby affecting the signal. It works on both 5GHz and 2.4GHz bands, regardless of distance from the router. It seems to be linked to the fire station next door, possibly due to their equipment interference. The issue occurs even when the area is unoccupied, though it tends to worsen at night.
The problem isn't limited to Wi-Fi. Analyzers will display nearby networks, not just your connection. 2.4 Ghz is common for microwaves, wireless mice, keyboards, Bluetooth, and more. 5Ghz is typically used by radar systems; usually only specific DFS channels are available. If your router supports it, it should detect radar presence and block those frequencies. You may need to talk to the service provider about this. Alternatively, reach out to the relevant government agency managing wireless spectrum in your area—they might clarify if emergency services use equipment that causes interference.
Additionally, I've experienced old routers overheating due to software glitches. Applying DDWRT made it run hotter, forcing me to cool it down actively. Eventually, it began dropping Wi-Fi connections regularly.
Yeah I forgot to mention I went and unplugged/switched off any device like that, even went though the kids toys cause RC stuff use it too. I can't see any radar in the settings. The router is a TUF-AX3000 That could be it, it's summer here and hitting 35'c days. I did find roaming assistant enabled it seems to discount devices if the signal gets bellow 70db. I switched it off to see if that will help in someway. If that doesn't solve it I'll stick a desk fan over it to see if it helps.
It might be the WiFi issue, but the internet could also be down. When the WiFi goes out, a wired connection usually still works.
It seems okay overall. The connected devices report no internet access. This behavior occurs with both routers, which is why I chose the second one initially. Disabling the roaming assistant helped reduce the issue, though it still happens. I note it mainly happens at night.
Absolutely, it also occurred with the older router. Since it came from the ISP, I thought it might just be a temporary issue.
A frequent problem when internet is unavailable is DNS not functioning properly. Changing your router's static DNS servers to alternatives like 1.1.1.1 or 8.8.8.8 might resolve the issue. After updating, reconnect all wifi devices so computers and phones receive the new DNS settings.
