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
How is your DNS configured / implemented?
Just default for my gl.inet, haven’t changed anythingon that part.
Given that you’re having issues with the DNS, I’d look at this.
Specifically, are you using the ISP DNS as an upstream lookup, or have you configured another DNS as the upstream?
Is the ISP DNS locking you out because you’re hammering it?
Does the ISP block traffic on Port 53?
When you’re having issues, can you look up addresses using a different DNS?
