Okay so i was messing around in the WAN settings of my TP-Link router. My connection is pppoe which is set in the WAN settings. I found out that there is a secondary connection option, and not knowing what it would do (perhaps thinking it would make my internet faster) i turned it on the Dynamic IP to see what would happen. Suddenly the router restarts and when i go to the IP address to login (which was usually 192.168.0.1) it directs me to a Tenda router instead. I don't have a Tenda router. Then it turns out that my own router changed its ip address to 192.168.1.1 and i successfully login and the secondary connection is connected (it gives me a local ip address though 192.168.0.102).

The main question here is why did it redirect me to a Tenda router when i don't have one? Could it be the ISP's? Is there any benefit for me to mess around in it?

And also what does that secondary connection mean? And what does it do exactly?

Thanks.

Edit: After looking around in the Tenda webpage, i found out that there is no WAN connection active, but there are 2 DHCP clients: Me on 192.168.0.102, and another one on 192.168.0.100, so after going to that link, it go to a webpage for a router that is MicroTik RouterOS, and according to google MicroTik provides wireless ISP systems around the world.

Edit 2: I'm going to remove the secondary connection for now until I know what am i doing. I don't to be cought by my ISP too.

Which area do you live in ?

Sainte-Therese, Hadat.
It's the ISP gateway.
in fact if you run cmd -> tracert google.com (assuming you're using window -- traceroute under linux) you'll probably see the IP address of that router after yours.
Some benefit? Yeah if you could get into RouterOS you "may" be able to speed up your line speed if, and only if your bandwidth is managed through that router. - The PPOE server may be running on another machine and this router is just forwarding data -
Keep in mind it's illegal to do that... But in case you did it, don't get excited and download like 500GB in one night. ISP will know.
I doubt ISPs use Tenda hardware it is not meant for ISPs, unless your ISP is the average local cable guy, in this case there is really nothing to hack in a poorly run network.

I Think it's the MikroTik one which is his not the Tenda, since the Tenda requires no login but i can't login into the MicroTik RouterOS one.

When i run the command i get request timed out after my own router, i also keep getting request timed out when i try to ping a website or an IP address.

I can't login to the RouterOS, default username and password not working.

There's often a username/password in the gateway
Hardly hacked into it if you dont have priviledged access.
I had a PPOE connection once and discovered that I could connect more than once using the same username/password and have parallel connections (using the Linux client), and then I'd use a download manager to do parallel downloads and boost my download speed.
This is a basic flaw and it was a long time ago, it's probably impossible to do that now, but who knows?

This worked until beginning of 2016. It wasn't that easy though, i had to change the mac of my router, to the same one of the owner's router.
If there is tenda upstream, just maybe some dude thiefing some isp by installing router with one connection and sharing to multiple people. Make sure u have legal username/password of ur isp.

When the cable provider setup the router he changes it to pppoe connection and by default the secondry connection is dynamic ip
And by dynamic ip it means to work as a dhcp client
The network of ur isp is poorly designed it dosent have filters beetwen clients
So that will cause a wide range broadcast of anything like pppoe-discovery or dhcp client broadcast search
Whats happening with you, that theirs another customer has pluged his wan cable not in the wan port ( the blue one usually ) but in the lan port (yellow one usually ) thats why you saw that theirs no wan connection, so his tend router will act as a dhcp server over the network and when you put the dynamic ip ur traffic is being routed to the tenda router that is for a random customer
And the reason you can see on the same subnet a mikrotik device its because it has dhcp client pre-configuerd by default and the guy didnt remember to remove it
Si theirs no hacking done :p
