Last friday I installed a RB750 at our small office environment but its underperforming badly.
We have a 20/20Mbit Fiber connection but after setting up the router we were able to do only 20/6 at best and averaging around 18/2.
Is this normal for the RB750? And what model should give me better results?
At home I am running the RB450, which allows me to upload my maximum upload speed (7mbit).
Would a RB450 be sufficient or would it be better to get a RB/1100/1200? Or are those slow on WAN as well?
Also, we are planning on upgrading our fiber to 100/100 mbit, would the 1100/1200 manage that?
Besides that, great router, only doing 2% on the CPU on average and memory stays under 10/15 mb usage. Very nice resource management.
Maybe you only have 6Mb Upload instead of 20.
The RB750 it’s enought for this 20/20Mbit connection. I have a RB750G with 100/100Mbit and it’s using the full bandwidth. The RB750 can handle this as well. It depends on how many Firewall, Queue, etc rules you have.
Connection is fine, done 20/20 speedtest on it without a laptop no problem. There are furthermore hardly any rules in it, just some port forwarding and thats it.
No idea why it is so slow
My uplink is 3 mbit/sec. I purchase RB/750G, create pppoe-client int and add srcnat from my gray net (192.168.88.0/24) to internet-interface.
RB is connecting, all good, except http-traffic - very, very, very sloooow and someting not response for timeout. Not but payload - 60mbit/sec in/out in ISP-network.
I personally do not trust speedtest, if you like to see actual throughput - make actual throughput. Run a torrent client and download several popular torrents, so that there are good number of peers. You will get proper load on device as there will be many connection entries in conntrack, as there are many remote sources/destinations your bottleneck will be your uplink or your router.
Problem with http traffic - it looks like DNS or change-mss problem.
Same problem here. A 45/45mbps fiber connection capped with simple queue at 24mbps.
On laptop tests are running fine (45/45), on RB750 download is at 24mbps but upload is at 9-10mbps.
I will try with dummy rules in firewall, and after that i will let you know the results.
I have the same problem but MIKROTIK.
I have fiber optic 50/50Mbps and when I plug in my laptop without the mikrotik router (it’s 50/50) but when I connect the mikrotik it’s 50/6Mbps.
is there anyone else that has his problem.
Negotiation problem maybe.. (it shows as duplex full though)

What is your router configuration? Do you use any /queue /firewall rules?
It would be great to see support output file and more information about your bandwidth test.
I have no rule at all .. I tried blank just with nat and also with real ips but it didn’t work.
I have no queues aswell. when I try to do mikrotik based upload speed overseas in europe ( from usa to europe) when i do send only it works also receieve only it works (up to 30Mbps) but when I do both it doesn’t work
I try to upload a file from my server to another server ( which I know has a good download speed) and it wouldn’t work.. it wouldn’t go more than 300KB/s
If using PPPoE or L2TP try adjust TCP MSS in PPP profile (check in Firewall Mangle). I was able to SRC-NAT w/Masquarade 45Mbit FDX with RB750G (Bandwidth test were run on x86 with 100 conn/1500 byte packets). RB750 can easily NAT 20/20 FDX.
