Well, It's been 20 hours since my router has been up and CPU spiked only once and that was when my internet was disconnecting a lot and when I went to check the router's page CPU was ~4.0, Instead of rebooting or checking the CPU usage this time after a minute I just let it be and after 15 minutes when my line got stable and internet started to work I decided to go check the router and hey back to <1.00 CPU usage I guess my CPU usage only spiked because I opened the router GUI when it was constantly trying to connect the PPPoE interface to get an IP.
All in all everything else seems to work nicely no issues there yet.
Do have a question though not related to this build but ima ask it here anyway. Since I have a PPPoE connection do I need to manually change my MTU size to 1492 anywhere in the router? If yes then which interfaces MTU size do I change?
If I leave the routers status page open after the CPU spike happens and goes back to normal CPU will instantly rise back up to ~3.00 usage. if I leave the router for 20 minutes and then open the GUI interface again CPU usage will be 0.02 something initially but will quickly rise.
Rebooted the router and CPU usage is back to normal doesn't rise even if I leave the status page open.
