For the past few days I've been experiencing sudden ping spikes at intervals of every 5-15 seconds, applicable to all devices on my network (wireless & wired alike). This isn't much of a consistent problem for streaming or browsing (there have been a few interruptions), but has been causing issues for both my roommate and I while playing online games (PC, PS4, and XBOX included). I ran WinMTR and can post the data retrieved if that might help troubleshoot the issue. Spectrum is my current ISP, and while the problem isn't absolutely urgent, I'd love to try out any ideas you might have before calling a technician out.
1) I've already power-cycled both the router and modem with no successful results.
2)The issue is similar on my wired PC and my laptop.
