download speed on MikroTik hEX PoE model RB960PGS

Hi Mikrotik power users

I have a question regarding the download speed observed on my MikroTik hEX PoE model RB960PGS.

My modem (Ubee UBC1318 in bridge mode) outputs 1000/70 Mbps (down/up) as measured directly at te modems port 1.
However, when connected to the router, I only get 95/70 Mbps. I use a cat6 cable between the modem and the router.

Is the router broken or is it a settings problem?
Being an absolute novice, I have no idea where to start looking for explanations or solutions. Any suggestions?

Can you confirm that you actually have 1 Gbps link speed between your router and mikrotik ? Did you try another cable ?

Sounds like a cable issue somewhere.
You should get around 600-700 down I would think.

I thought the MikroTik is the router. Between modem and router (the mikrotik) I use cat6 cabled. The modem outputs 940 Mbps when measured directly at its output port.

I don’t think cables are the problem, but some internal settings of the router.

@gigabyte091 was being vague. Some people use a plain modem, others run their ISP router in bridge mode so the RouterOS box is the only proper router, and still others must run their ISP router as a router with a RouterOS box behind it doing the hard work. There are even systems that try to blur the difference, which have no proper bridge mode yet which still get their own IP, yet without taking over the main routing tasks.

Without knowing your ISP and local setup, “router” is a fair guess at the particular class of box between your hEX PoE and the ISP.

Could be. We aren’t going to know until you post the configuration. SSH into the router, say “/export”, then paste the result into a “code” block here in the forum. Edit out sensitive details like serial numbers and personally identifying information.

Okay, so your ISP modem outputs 940 Mbps but does your ISP modem and mikrotik negotiate 1Gbps link speed ? Because your problem seems to me like they negotiate 100Mbps speed, so go under Interface → Interfaces → select interface where your ISP modem is connected and click status and see what is under Rate.

By default autonegotiation is enabled so you must get 1Gbps.

If you don’t believe me, believe anav :laughing:

Well I wasnt talking specifically about the modem/router negotiation.
I was simply talking throughput capacity on the WAN side of the hex and you will get around 2/3 max of your ISP speed.
You really should look at the
a. hapax3 to optimize a 1 gig connection 9 no need to use wifi if dont want it.
b. rb5009 if you have the budget.

RB960PGS has a small CPU, is Mandatory to use Fast-Track mode if you want to achieve some decent speed, even with Fast-track i dont think you can achieve 1.000 megabit/s consistently

Is ethernet flow control enabled on the interface to the modem?
