PPPoE connection painfully slow on CRS109-8G router

Hello guys!

I’ve tried to set up a PPPoE connection to my ISP on ether1, which seemed to work, and a LAN on bridge1 containing ether2 to ether8.

DHCP server works, pppoe-out1 connects and I seem to have internet access on the lan side. However, it is so slow that it might be faster to phone Google headquarters and ask someone to fax you the first page of results for “does my internet work”.

I have tried playing with firewall rules, ip routes, everything i could think of. I am at a complete and utter loss right now. I ended up resetting and configuring a HomeAP through quickset just to make sure i am not going insane and the stock configuration really is painfully slow.

Could any of you throw a stick in the general direction i should go towards?

My configuration is as stock as it can be. I only added the PPPoE user and pass and set the local network to 192.168.1.0/24 instead of the default 192.168.88.0/24. However, if you need any info or config, ask me, but please tell me where to get it from ah I have close to no experience with RouterOS.

PS: by slow I mean I get around 50 ms ping, 100-2000ms jitter (yes 2000), 0.1mbps download and 0.0mbps upload. Pages load like on the good old dial up connection. Even that was more reliable.

Thanks a lot!

What if you connect a computer directly to your ISPs Router? Does the Internet perform as expected ?

My ISP gave me an ONT ~7 years ago. It has been running on a WDR3600 until yesterday when I decided to install the Mikrotik router i’ve had laying around for the last couple of months. I got it from my dad as the router’s firmware went belly up and he got some consumer router as replacement in a pinch. I reflashed the Mikrotik and used it as eth1 wan with dhcp.

Anyway, the internet connection kept dropping at least once per day, only getting fixed by either waiting for a couple of hours or unplugging and plugging the router and ONT back in, and I am not sure whether the ONT or the WDR3600 was bad. So I wanted to try another known good router but it appears as if I can’t make sense of some pesky settings or something, despite coming from a computer science background and having worked with cisco products.

As for your question, Zacharias, I’ve deleted everything from the router and added eth1 to the bridge, essentially turning the thing into a dumb switch. I configured my pppoe on my PC and, suprise surprise, ping went down a little, but everything stayed the same. It is quite difficult to reach the router and ONT as they are mounted in a box on the side of the house, ~3m in the air.

I am starting more and more to thing that either the Mikrotik is bad, thr ONT is bad or both are bad.

Connect your Computer directly to ONT… nothing else between…
Then make your tests…

Works as expected, 700-800mbps, when connected to the ONT directly. Can’t comment on reliability as i am not able to keep my pc connected for such a long time.

Am not sure what might be going wrong…
Does the CRS has the default config ? Is fasttrack enabled ? Updated to latest ROS?
Did you test with only your computer connected and nothing else ? What traffic do you see on the PPPoE Interface during the speedtest?
Also do not expect anything higher than 200-300 Mbps… https://mikrotik.com/product/CRS109-8G-1S-2HnD-IN#fndtn-testresults

Default config, fastrack enabled, lastest router os. Traffic on pppoe interface is between 0 and 500 bytes per second.

200-300mbps is still way higher than what i’m getting. In another setting, dhcp client on wan eth1 and dhcp server on lan bridge managed to route at 800mbps tho.

Faulty unit, perhaps. You wrote previously that it’s firmware had previously “gone belly up”. That incident and the unit’s current slowness may as well have common roots.

Maybe, but only with PPPoE? I am currently using it as a router with dhcp wan and i’m pushing 600mbps, limited by the router higher up the stream.
