I have been seeing periodic drops in internet access from LAN connected devices lately (last 2 months), and I haven’t been able to figure about exactly what is going on. There doesn’t seem to be a pattern, and it resolves itself after a few hours.
- I can access the internet from my router
- All devices on LAN can reach each other, both wired and WiFi
- All devices on LAN can reach router, both wired and WiFi
- I haven’t changed anything in router settings
- I haven’t added new devices to my local network
- I can’t find any IP conflicts
- It’s a simple flat network with two APs, a single switch, no VLAN separation
Internet access from all devices in my house simply stops working entirely for a few hours, sometimes there’s weeks between this happening, sometimes only a few days. But when this happens, I can still reach internet from my router without issue.
Does restarting your router help in these moments? Might just be an underpowered router
Do your devices use the router’s DNS? If so is it still reachable? From the client? From the router machine?
Might be some kind of DHCP bug too but I’m not well versed in it
Restart doesn’t fix it unfortunately.
I am using my routers DNS, and it’s reachable from my laptop.
