Constant packet loss

Question

Currently running U6-LR with a wireless uplink to a U6-Lite. Keep getting this. Feels like I've tried everything to reduce this, but any other suggestions will be helpful. Cannot hardwire the U6-Lite.

First step is to understand why you're losing ping replies.

Do you have interference between the APs? Other APs (neighboring) on the same channel, a microwave running nearby, etc.?

And how % packets are you losing roughly, is this affecting your network negatively?

Nothing significant on the 5G. Losing between 0.5-6% of packets depending on time. This impacts voice calls, online gaming, etc.

Can you see the signal quality between the two APs?

92% (-53dbm)

I'm out of ideas on what's causing the packet loss, I hope others have ideas here.

Are you only having this issue with the wireless AP? I would use the Wifiman App and netspot to troubleshoot clear Wifi signal and channels. You may have to reduce channel width to minimize interference.

You're pinging something on the internet, there's at least 4 more components (potentially dozens) between your device and 8.8.8.8

What's the interval between pings?

Is your device switching APs while the drops occur?

Do you see the same packet drops between your device and the Lite AP itself, your device and the LR while connected to the Lite, your device and the switch and/or router hooked up to the LR, your device and the isp dns server, your device and say the quad9 dns server 9.9.9.9?
