  @oller Wow, thanks. I have been having these ping spikes too, perfectly periodic, about every 6-10s. Small, regular

 

 

I experienced this on my Macbook pro 2022 and my intel imac 2021. So far as i know, neither of these devices use realtek wifi chips (pretty sure they use TSMC).

 

Anyway, **disabling the Mesh did _not_ fix it**. However, **disabling the 2.4 Gz range signal _does_ appear to have resolved it**.

 

My setup:

 

3x deco x60. latest firmware.

main deco *not* in router mode (LAN cable to ISP-provided router)

Previously: both 2.4Ghz and 5GHz on same SSID

Now: Just 5Gz signal.

 

What's worse is that ping from the imac _to_ the macbook was off the charts (range of 15ms to 4s, mostly > 500ms). This made no sense as the devices are literally next to each other, albeit connected to different decos for _hand wavy_ reasons explicable only by Apple's wifi driver author. After disabling the 2.4Gz range, ping to the other LAN device is _better_ but still extremely variable. This seems odd to me, as ping to 8.8.8.8 is stable.

 

Example:

*sigh*, spent like 1-2 month investigating why my deco were performing way more terrible after we moved to this new house, just to realized we've switched from using ethernet backhaul from every deco to only using wireless connectivity between the decos, Thanks to this one person on reddit for mentioning it
