Hi!


I have my network extented with the TL-WPA4220KIT
and have problems with my IPTV lagging.


My IPTV-box is connected to TL-WPA4220 with
RJ45. The IPTV runs just fine IF I´m not
using the network on other devices that are
connected to the WiFi from TL-WPA4220.


I have measured the speed of internet from the TL-WPA4220
to the Tv-bBx and it´s about 70 Mbit/s, both upstream and downstream.


It starts to lag even if I´m using things that don´t require
alot of bandwith, for example using Facebook or Instagram
on a smartphone (the network isn´t used by something else when
doing this).


The units of TL-WPA4220KIT has been set to Audio or Video
in the QoS settings with the TP-LINK utility.


If I use a RJ45 cable directly from the router (the same router the
TL-WPA4220KIT is connected to)
to the TV-Box the IPTV doesn´t lag under the exact same circumstances.


I have also given the MAC adress of the TV-Box highest priority
in the QoS settings on the router.

Has anyone found a solution to this problem already? Because it's happening to me too

For live IPTV, every single one of your infrastructure devices (router, switches, PLCs, WLAN APs, ...) needs to support Multicast routing (aka IGMP) correctly. If just one doesn't, then Multicast traffic will fall back to Broadcast. This will flood your entire network, with typical symptoms exactly like you describe.

IGMP is generally supportable in PLCs. However, vendors are free to actually enable it or not. TP-Link devices are pretty patchy in that regard - even on the same device, firmware updates have been adding and removing the feature seemingly at random.
