Weird and consistent lag/latency with new AX82U router

[Mp69]

Hey yall,
I just bought a brand new AX82U router and hooked it up to my Arris SBG8300 in bridge mode due to lacking range. This router has drastically increased my wifi range on both bands including better speeds. I set it up with both 2.4 and 5G bands, and used most of the default settings. I've got two gaming rigs in this house plus phones, laptops, and tvs all on wireless. Unfortunately, I can't hook ethernet to either of the rigs, and I've had them almost completely solo on the 5G band. While gaming both computers experience packet loss or large latency (I think?) in a continuous patter. It happen about ~10-15 minutes apart and includes one major spike, a pause of working internet, and another major spike. I've check a few other posts and changed my settings according to those, plus I have checked the system logs and those show nothing. I have done packet tests where I am pinging a server and had it going for over 25 minutes with nothing happening. I don't really know whats going on. LMK if you need more info or tests.

Did this happen before you installed the AX82 ?

Does this happen if you hardwire to a LAN port on the AX82 and game ? Either move your rig or get a long temporary CAT5e or 6 cable to test.

So it doesn't seem to happen when hardwired. I've now noticed that it happens with nearly every device, but especially noticeable under heavy load. No, it didn't happen before I installed the router.

AC clients tend to have deterministically reproducible ping spikes on AX AP's, I gave up trying to identify why that is on my network and just dedicated the older AC router the AX router replaced to those devices.

Ah, that's interesting. Unfortunately for me this ping spike happens on ax devices also. Both of the rigs support wifi 6, and my phone also seems to take forever to connect at certain points. I kinda expecting more out of this router.

Do you see these spikes on AX cards made by Intel? Because that is the issue with Intel cards, I have two routers - RT-AX82U (Broadcom-based) and RT-AX59U (MediaTek-based), and on both routers I experience packet losses on AX211 approx. every 10 minutes when using Geforce Now cloud gaming service (Ethernet works fine). On AX82U, this interruption lasts a bit longer, but more torelable (the stream lags for longer, but it does not affect the game much), while on RT-AX59U it occurs for a shorter period (a couple of seconds), but affects the stream more (for example, sometimes making it impossible to stay on a track in a racing game).

You can find lots of posts on Reddit and Intel forums about this issue, looks like it is somehow related to the background scan that is periodically performed by the Intel card. Intel even had an option in the driver settings that allowed users to disable this feature, but, unfortunately, it was removed about a year ago.

They both are cards made by Intel so I'd say that would make sense. I'll switch them both to ac instead of ax when I get home later, and see if that changes it at all.

Disabling AutoConfig on the intel adapters will resolve this on drivers after 23.40.0 (or use a older driver, stationdrivers has them archived)

in command prompt

netsh wlan set autoconfig enabled=no interface="Wi-Fi"

This post is more of an update from my last post with more information because I was wrong. I recently bought an AX82U and I have it connected to a Arris SBG8300 in bridge mode. I've had a reoccurring issue that would cause 100% packet loss to any connected session, but not from pc to router. It'd lag for ~7 seconds the be fine for ~5 and lag again. This happens almost every 10-15 minutes but only under some type of load. I found that it won't happen if I am just pinging a server constantly. I've attached a ping plotter image that shows the packet loss when pinging 8.8.8.8 and this will happen when my pc has any high internet using games or streams.
Old Post: This was my old post, but none of the solutions offered made any positive changes.
EDIT: I've found that the packet loss happens every 16 minutes almost on the dot

You need QoS because you have a assymetric connection and your uplink is saturated.

Put your SBG back into routed mode - and config your Asus device into AP

Should sort your problems...

Or ISP provided device in router/gateway mode with Wi-Fi disabled and Asus in router mode in DMZ, may help too.
