Things have been mostly fine with my OOL leased Sagemcom (or Altice?) router until I recently added another hard-wired Ethernet device to it. After adding that new device, my Windows PCs have been reporting "No Internet" on the connection on and off. Sometimes my wireless devices connect to Wifi but say "Wifi connection is unstable" and I basically have no internet. I also get frequent DNS timeouts.
Overall, I now have 6 ethernet devices and 3 wifi devices. I've been power cycling both the modem and the router on a daily basis to alleviate the problem. The new device does not have to be powered on for the problem to occur.
Any ideas? Could it be that the router can't handle so much NAT overhead or something?
