Hello again.Sorry for the long wait, i was very frustrated with my problem and used another basic router. When i was informed about changes in dumaos, I Installed latest beta firmware + cloud update (for dpi changes). Now web surfing a lot smoother and most important - no ping spikes in games (at least online games are playable now) . I tried wired and wireless gaming. By the way i did factory reset after update ,but settings the same what i always use.
I really hope this is not temporary changes and i can play games without problems. I will inform you if the problem reappear
I thought i m the only one who have this issue.Except my router on 3.0.205 firmware.I have this issue in MW2019 and BO4 on ps4.Also i played Fortnite [xbos series s] a little bit and faced simmilar problems.I have tested LAN and WiFi connections and no difference, ping spikes on both. I thought its servers, now i suspect its R2. I will need to test this games with different router
