Devices Rx and Tx rates dropping
I have an Amplifi HD set with two mesh points. I am experiencing throughput drops which render devices unusable- hoping for help!
Throughput on Wi-fi devices keeps on dropping, causing internet to crawl. This appears to mostly be happening with apple devices, an Apple TV and iPhone Xs’s.
These devices connect normally at 500mb+ Rx and Tx. However, when experiencing issues the Rx and Tx drop down to 6.50mb. This results in crawling internet speeds, rendering the devices unusable. A restart on the device and/or the amplifi HD resolves the problem, until the next time it happens.
I have tried:
- Factory reset
- Hardware NAT
- Various firmwares
- Changing channels
- Band steering on / off
Before I chuck it out the window, any ideas?
@jamie-vague I understand that the r/k/v, A-MSDU, band/router steering, and some other settings give Apple devices problems when they're enabled because of their custom (wonky) implementation of a lot of WiFi things. I would suggest starting out with just stock settings (enable Hardware NAT if your ISP is over 400mbps), and troubleshoot from that configuration.
- Does this happen regardless of which node the device is connected to or does this only happen on the mesh nodes?
- When you roam from one mesh node to another, does it resolve things or are speeds essentially "pickup up where they left off" from the previous mesh node?
- Have you tried hitting your phone with a hammer to see if it fixes it? (I can tell you right now, pretty much every WiFi appliance manufacturer hates dealing with Apple devices.)
@jamie-vague This article instructs you on how to navigate to the WebUI : https://help.amplifi.com/hc/en-us/articles/220978907-Does-AmpliFi-have-a-web-interface-
That is where the 802.11 r/k/v and A-MSDU settings are located that @Shane-Milton was referencing.
P.S. I do not recommend step 3 in Shane's list
@shane-milton Thank you for your help, much appreciated.
I will try disabling A-MSDU and see if any improvement. What does A-MSDU do?
It is defiantly not an issue isolated to a particular access point. I happens when connected to any AP, including the base router.
Will monitor if roaming has an impact next time I have the problem.
@jamie-vague how many hours or days does it last before the issue hits because I think this warrants my feature request for clearing the cache or memory of both mesh points and router, and user set reboot schedule.
