Hey! I have very similar problem with Czech O2 TV and Archer VR2100, which I bought few days ago for my parents. I use same settings as you. The problem is that live stream does not reconnect after router reboot (parents turns the router off over night). After the start, logging into settings and saving IPTV configurtion (with e.g. changed priority) recreate the live stream. Note that only the live stream is not working -- if we time shift just for 1 s back or reply an old broadcast, it works. But this is probably because playing non-live streams uses standard connection and IPTV settings is mostly for the live stream in real time.

Thank you for your input.

The issue seems to be really the same. Basically I am also doing the workaround to open Teether App - IPTV/VLAN setting - and doing here some minor nonsense change (for example changing VOIP VLAN which is not used at all). After saving it, the router will apply the new settings, connection is lost for a few seconds and when router is restored then IPTV will start working again.

I need to test what you said, if I will time shift any program to the past, if it will work or not in my case.

Anyway, it seems now more as issue on TP-LINK side with VLAN settings. Don´t know exactly what is broken when Internet VLAN is working fine all the time, but with the IPTV vlan there is some issue and it is not reliable all the time. :(

Could you please tell me what generation of O2 set-top-box is used by your parents ? When I will have the chance to test the latest O2-set-top-box (3.generation, SML-5442TW) I will try to find out if the behaviour is same or not. At the moment I am using generation 2.1 (EKT DID 7006) where the issue persists.

@MikeMaster , parents have: iP4.tv EVO4-T. So it seems you have newer than we have. You can find more on this page: https://www.o2.cz/osobni/techzona-set-top-boxy/set-top-box-pro-o2tv.html?article=445365

But I believe the problem is in router firmware and maybe something special in O2 network. Today, I contacted TP-Link Czech help line and they asked me for screenshots of settings. And now they investigating the issue...

@czdosi 

Thank you. I also think the problem is not in the 02 set-top-box. At least I know this is happening on two different types of O2 boxes

Just for your information in my house I am using VDSL bonding, so the first network device from ISP is the so-called "terminator" and it is connected directly with Archer AX10.

We did not get any issues when we were using old router VDSL modem Zyxel VMG1312. Then bonding was done in my house and I directly upgraded to TP-Link Archer due to network capability and other features. 

Have you tried to run O2TV just via Internet, not via IPTV VLAN ? Does the issue still occur on your side ?

Please let me know if your will get any progress with TP-Link Czech support. Thank you.

I have some update on my side.

I have bought the latest generation of O2 set-top-box (3 generation, used sml-5442tw for a very good price) and replace the old one . The LAN/IPTV configuration is used same as it was on TP-Link Archer AX10 side. So far everything works good. After first night, the IPTV still works, but it will take more days to be really surre if the issue gone.

One reason why the latest O2 set-top-box might be helping with this issue is the active sleep mode. When O2 set-top-box is turned off, it is acutally is some kind of active sleep mode and when it is turned on again, the complete booting process is not done as it was with previous O2 set-top-boxes geneartions. So you will directly get the main page and in my case picture and sound is working. But it might also be something else, let see.

I bought it also because of bluetooth remote controler as all my devices connected to TV are closed in the TV cabinet.

Is there any update from your side ? Did you get any feedback from TP-Link Czech support ?

UPDATE: After two days in use it seems IPTV works fine without any issues. :)
