I have a TP-Link NX510v 5G router from my ISP with 31GB ports. When I connect my PC to it via cable, the speedtest (not btest) goes up to 600-700 Mbit/s. I also have a Routerboard hAP ac^3 (RBD53iG-5HacD2HnD) with 51GB ports. The RB currently has no def confing, only a bridge with 2 ports and a DHCP client on it. Everything else is disabled.
When I connect the RB to the ISP router and to my PC with CAT 5e SFTP cables the maximum speed I can reach is only about 60 Mbit/s.
At the beginning it shows 300 Mbit/s but it goes down to 70 Mb/s very fast and the result is mentioned earlier.
What did I set wrong?
Earlier I hade an other ISP and the RB produced 300 Mb/s constantly (which was the actual speed of that plan) so I know it is capable of doing it. The problem must be somewhere between the MikroTik and TP-Link connection. Does anyone have experiences with them?
Firstly, if you have 1gig port speed on TPLINK , then 600-700 on your PC sounds like a limitation on your PC, should be getting 950ish…
Secondly, without knowing how the HAP is configured and what the TPLINK settings are, cannot comment on slow speeds.
Use other cables to rule out that possibility as an issue.
The 1 GB is only stands for the port speed. The network plan is a 5G connection with a name “1000 Mb/s”. Of course in ideal circumstances it can reach 1000 Mb but it’s never guaranteed. 700 Mb/s is enough in 75% network coverage.
My problem is that with MikroTik I can’t reach that 700 like I do using only the TP-Link, only 60 Mb with RB which is very poor. I don’t “care” about the 950 Mb (I know it comes from the 1000-1024 difference), I know it’s just a marketing phrase.
The cabling can’t be the bottleneck because I have used these cables in the earlier setup and it worked with a constant 300 Mb/s. Also I have tried both cables in between the PC and the ISP router, and the result was the same, about 700 Mb/s.
As I wrote earlier, the RB has no def config. Just a simple bridge created with the plus sign, without any further configuration. 2 ports in it, and a DHCP client. I can show show you the export, but you won’t find anything there, because it works only as a bridge.
On the TP-Link side, the Advanced options are not so Advanced neither (like a simple SOHO router usually). I can’t even set any MTU. That is a def conf TP-Link router, so I don’t know what else could I say about it.
If you have any questions about it, let me know, and I will look for it!
Can you share the hAP ac3 config? Just to make sure…? And what RouterOS version are you running?
At what speed are all the devices connected to the hAP?
With CAT 6 S/FTP cables the speedtest starts with 200 Mb/s and goes down to 100 Mb/s. I admit that it’s a + 30 Mb, but I think it’s still far away from 700-950 Mbit/s.
Here is the export:

With a directly connected CAT 6 cable, the speed test does a 600 Mbit\s, but the weather is not the best currently, so it may interfer for the 5G data connection. Of corse the 1000 Mbit/s name is still a marketing phrase for this plan, so 950 Mb/s will never get real.
The ethernet ports are on Auto Negotiation, but their status is 1 Gbps Full Duplex, so it seems quite good. Also my notebook has a 1 GbE LAN port, with a default MTU of 1500.
These problems are related to the ISP’s hardware settings. It has nothing to do with the Mikrotik.
Turn on the TP-Link NX510v to the ISP and connect the Mikrotik between the computer and the TP-Link NX510v and check the speed.
The NX510v is the ISP’s modem/router. The MikroTik between the TP-Link and the PC is the current setup, and it causes poor speed somehow, because without it (so the PC directly connected to the ISP’s TP-Link) it’s quite good with that 600-700 Mb/s.
