While using Solus, my wifi connection will randomly drop internet access, though NetworkManager shows me having a good connection to the network. A disconnect and reconnect is enough to temporarily fix the issue until next boot, though I turn my laptop on and off often enough to make it an annoyance.
A possible factor in this is that my university has a network of routers scattered across campus to provide students internet access from anywhere. The routers all use the same SSID to make switching between routers seamless, but perhaps Solus is having issues with that? I have Arch Linux installed on this laptop as well but it is having its own internet issues right now (working on fixing it now), though last I recall it was not having this same issue.
