I have been getting random intermittent internet connections on few particular devices. Let us call these PC1, PC2 and Mobile1. PC1 and PC2 are wired connections and Mobile1 uses wireless connection. Both PCs run linux and I ran a test on windows on same devices and it did not show the aforementioned problem. Pinging the router from any of the three devices shows significant packet loss (anywhere from 10-40%). The thing is, nothing has changed, neither the router nor the system configurations and the problem started out of nowhere a few days ago. I can ping PC2 from PC1 or Mobile1 and vice versa successfully with no packet loss. This cannot be a DHCP issue, since I have already tried setting various static addresses. And I do not think this can be related to the ISP either since the router is causing the problem(?). What could be causing this problem? Why did the router start dropping these packets out of nowhere. Note that all other devices, wireless and wired, still work as they should. I apologize if this is not an appropriate place for these questions.
EDIT:
Things I have tried:
- Setting a static address for all 3 devices: It made no difference
- Rebooting the router a lot of times
The network device models should not be an issue since the issue was not there a few days ago with same configuration
The diagram can be as simple as this
