I'm not sure what channel the Deco is set to, as it doesn't allow manually setting the wireless channel, it's just set to auto. The hAP is also set to auto.What wireless channels are being used on each device?
What speed do you get if you cable in to the Deco?
Yes, the Deco is a mesh router/AP. It's still interesting that this issue only started happening after I replaced my Asus router with the hAP. And I had wireless disabled on both.If you leave things in "auto", then slow wifi will be what you get in most cases.
Take control!!!The Mikrotik can set the channels in 2.4 and 5 GHz. The Mikrotik can SEE the channels used by the Deco.
You probably have the DECO TP link E4 set up as a mesh network, if you have more than one AP in the kit.
For sure you have some wifi conficts in the setup. (co channel interference, adjacent channel interference, large bandwidths, power unbalance between AP and client, etc etc etc)
E.G.: If you use the DECO E4 on its 30 dBm power (FCC allowed, illegal in Europe anayway) for 2.4GHz then you will have good signal (5 bars) and good coverage, but no throughput.
And that's all because you just use "auto", and for the rest makes classical beginners intuitive assumptions about wifi.
But:
"Wifi on auto will slow down until it works."
"Wifi is bidirectional. The weakest radio will define the connection. High power AP's are misleading to the receiver and to the user"
So no wifi involved here. If the ethernet ports don't do what is expected. This must be cleared first. Can you use "speedtest.net" to eliminate the file download server? Those download test sites are a bid more stable in performance than is the case in downloading a file. If the problem persists, then the interface status and counters and the log in the Mikrotik will also be of great interest.UPDATE:
So I wanted to check if the same issue happens over wired Ethernet connection.
I've tried the following:
1. I unplugged the Deco
2.I made sure that wireless was disabled on the hAP.
3.I disconnected everything from the hAP except the WAN cable
4.I connected 2 laptops to the hAP using Ethernet cables (both computers have a 100Mbit Ethernet port and also both cables are 100Mbit)
5.I started downloading a large file on both laptops (the file was exactly the same on both)
One of the laptops was downloading at approximately 950KBytes/s (which is very close to our actual speed - ~1.5MB/s) and the other laptop was downloading at around 20~30KBytes/s.
Then I did the same exact test, same setup except I changed the router to my old Asus one.
Now one laptop was downloading at ~510KB/s and the other one at 540KB/s. So the bandwidth was much more "balanced".
I couldn't test the Deco as it has only 2 Ethernet ports and one of them is used as the WAN port.
Here are the test results:So no wifi involved here. If the ethernet ports don't do what is expected. This must be cleared first. Can you use "speedtest.net" to eliminate the file download server?
