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
From my laptop I can ping outwards using IP, but not names (e.g. openwrt.org), but I can reach my DNS from my laptop
Okay, well, that’s a pretty good indication that marud’s guess is right and it’s DNS-related, if you can reach hosts by IP but not by name. Is the laptop Linux?
