Hi,

Just noticed that I started to have a problem with upload speed. Not sure what it could be connected with.

I have AC86U as a main router connected to AT&T ARRIS - BGW210-700 and 2xAC2600 (blue cave) as AiMesh nodes. I'm using a Gigabit plan for a while now and max speed I was able to get is around 450Mbps up and 450Mbps down (even tho att modem integrated in UI speed test shows around 976.562/906.497 (Mbps down/up). Currently the picture is the following:

Tried on a bunch of devices that I have including phones (upload is not getting above 150Mbps). My desktop usually connected via cable to one of the AIMesh nodes that is nearby and speeds were usually 400+Mbps both ways.

Today I updated both blue caves firmwares, just to exclude em from equation I turned them off an connected to AC86U and run few speed tests, results were the same as on the screenshot.

Didn't change any router settings - so not sure what could lead to the upload speed dropping.

Here is some wireless settings I have:

2.4Ghz:

5Ghz:

Since last firmware update I didn't touch anything in router setup.

Any advice where to check or what to do to identify the problem?

Was the speed test running on 2.4 or 5 WiFi. Sounds like 2.4
