So I have a headache of a network problem and either I'm doing something wrong, which I can't believe or something is not right.

Anyways so network is pretty straight forward. All devices ( excluding adsl router ) plugs into a 16 port switch. Mikrotik RB750 also plugs into Switch. DSL Router plugs into RB750.

Now a few weeks ago the adsl was a dlink 2640U which started to lock up, having to reset it daily. Internet account is dialed from mikrotik. So I replaced the dlink with a 2nd hand tenda, set to bridge, pppoe connects after 5minutes of attempts, holds connection for 15s then drops. Thinking its the router, I go buy a nice new netgear only to find out it doesn't have bridge ( dialing from the mikrotik is required ) so I take it back, get a brand new latest tenda. Connect everything and attempt dialing. Same thing happens as previous tenda.

Heavy frustration is starting to sink in, so thinking tenda is most likely just a pos and always broken I now go get a TPLink, after hearing great reviews. Plug it in, start the pppoe session and to my disappointment, it is still doing it.

Is it possible that the mikrotik is buggered, I mean the ethernet port works... surely pppoe is a software thing ( btw recently updated it ).

Edit: Internet also seems slow at times. I barely see full line traffic moving through the tik.

I really don't know what to think now... I'm at that point where I must be the problem :cry:

Since you have lik eten million modems / routers now lying around, why dont you use one of them to dial the pppoe connection and see if it works.
If so, then its your mikrotik.
Doesnt the mikrotik have logging for this?

Use the netgear router to create the connection and see what happens.

Well dialing from the modem itself and just routing it appears to work, but I am more knowledgable with mikrotik and gives me more functionality, like torching the connection if I suspect line hogging by a downloader.

This is from the mikrotik log, it only gives connection status, not what happens to it after its connected.

Code:

As you see, connection eventually works but very briefly. Following log message will just state :terminating... - disconnected.

Any chance it's the line and not the network at all?

Well our line was installed diy by the landlord and crackles on the tel line from time to time but as above, dialing direct from modem works 100% from what i can see.

As per above, tested and works but it's not ideal for me as the tik gives more functionality wrt troubleshooting.
 
It's not possibly trying to open more than one PPPoE connection and so your ISP is dropping the link because your account is limited to one concurrent connection?
 
What if you ARP ping the router? Does that also drop at the same time?

Will check that out.

All I can think is that it might indicate if you have a physical port/cable problem of some kind between the two devices and that it's not strictly the PPPoE session itself breaking.

ARP Ping doesn't drop at all.

I have noticed that i managed to hold a ping for a lot longer so I had a look and found the NAT's weren't enabled so I fixed that and as soon as traffic hit my pings timed out and connection dropped.
 
Have you tried getting Telkom to reset the port at the exchange. Sounds like the connection is 'flapping'.
