Model: Archer C6  
Hardware Version: V2
Firmware Version: 1.3.2 Build 20201126 rel.35321(5255)

I am trying to configure the router as l2tp/pptp connection.

 

1. pptp works but i experience some weird stuff. I have internet connection only if the router is connected to vpn server. It is strange because my old router TL-R460 has internet connection even if it is not connected to the vpn server.

 

2. l2tp doesn't work at all. Again my old TL-R460 router has no problem to connect via l2tp.

 

Is my new Archer C6 broken? I have latest firmware version. What is wrong with this router?

Hi,

 

In case you are trying to use that L2TP connection feature of the Archer C6 to connect to a L2TP/IPSec VPN server, than that won't work, because it is missing the IPSec part.

 

Apparently TP-Link provides the PPTP and L2TP protocol support in the Internet connection settings of the router purly for the purpose of establishing Internet connections with ISPs who require it.

Are you referring to the L2TP/PPTP connection on the router WAN? If that's the case, that is the WAN connection provided by your ISP, so you need to confirm with them, whether you should use L2TP or PPTP. 

 

What's more, you can only access the internet when the WAN connection is built-up successfully, I guess that's what you are referring to as per issue 1.

Not really. For WAN connection i use only static ip. I use pptp/l2tp only if i need to have internet via vpn server.

I also have old TP-Link TL-R460 router. And i don't have any problems i mentiond with it.

l2tp works just fine and i have internet even if the router is not connected to vpn server.

The only peculiar thing is that TL-R460 has IPsek key option which is absent in Archer C6.

Thanks! This probably answers why there is no internet connection if connection to vpn server is not enabled. Because this router expects full config active.

Now i am a bit dissapointed by this router. Yes, it is not the preimium router but my old TL-R460 tplink router is not premium as well but it is much older.

I didn't expect that new shiny router would have reduced functionality.
