TL WPA4220 DUP packets when using WiFi
TL WPA4220 DUP packets when using WiFi
2021-10-27 10:16:24
Model: TL-WPA4220
Hardware Version: V5
Firmware Version: 1.0.1 Build 200811 Rel.68784n (6985/8575)

I have my TL WPA4220 connected via ethernet to back of BT home hub dsl router/modem, plugged into mains power line and then the other unit using 2.4G wifi and/or ethernet to laptop.

I have BT hiome hub as DHCP server and the TP devices set to use dynamic IP so it gets address from BT Home hub as do all devices connecting to the TP link device.

 

When I use WiFi on the TP device (only supports 2.4g) I get duplicate packets when pinging the default gateway (my BT homehub).  When I switch to connect to TP device by ethernet cable I never get any DUP packets.

The DUP packets I believe are the source of intermittent slowness and drops in throughput which affect zoom calls etc.

 

No firmware update available.

 

Any ideas?

 

thanks

@KennyG Hello, 

Thank you for your detailed post. 

1. We update the firmware on local website for WPA4220 V5 , please give it a try: 

How to update the firmware of Powerline ac Extender via web-based management interface (new logo)?

 

2. Please try a different Wi-Fi channel for tp-link device.  You could download Wi-Fi analyzer app or software and select a less crowded channel

Lower Wi-Fi channel width to 20MHz will also reduce the interference, but this will sacrifice some speed. 
Here a guide to login web page : https://www.tp-link.com/en/support/faq/1417/

 

If  the concerns persists , may I know does Wi-Fi intermittent issue  happen on  all wireless devices, how often does happen, how does that recover?

Can you share  the ping results.  When issue happen, what are the network actives e.g. Zoom when this happens? Thank you

@Solla-topee Thanks - I just loaded the new firmware.  

Unfortunately I still get quite a few DUP packets:

Below is snip of pinging my default gateway from laptop.  Laptop connected to TP link WPA4220 via WiFi.  WPA4420 connected to mains to other TP device which is ethernet cable into back of BT home hub.

The Wi-Fi signal is strong with very low interference.  I've tried other Wi-Fi channels but no difference.  The laptop is 2m from Wifi device so don't think I can do anything better in terms of signal strength or reduced noise/interference.  See below taken from laptop WiFi status. and the ping results.

Any ideas as it means using WiFi is just not reliable

thanks

Ken

@KennyG Thank you very much for providing the more case details.  It does not look like the IP conflicts as the DUP packets are just a few, as your concern is the intermittent  issue during Zoom call, we may start from that point and do some further troubleshooting. We would like to have a specialist look into this further through email, please check your inbox later. Thank you!
