Speed less than 20 Mbps

Thu Jul 13, 2017 3:49 am

greetings to all, recently purchased access point wap ac, speed measurement showed that it gives 20 Mbps less than the old router from another manufacturer, all tests were performed on 2.4 GHz, disabled the firewall, no special settings are not made,the impact speed is great, the understatement of only the inbound traffic, how to achieve speed as on the old router?

Check the speed you are connected.

I've spent many hours trying to get better wifi speeds out of various Mikrotik products. I've never gotten anything better than 20mbps for 2.4 Ghz. My solution was to go with another brand for wifi, but I still use Mikrotik for Routing, VPNs, etc.

Others have posted this same problem. I've followed their threads and a solution never shows up.

Seems odd, I just installed a cap lite in my lab environment so I thought I'd try this out. I setup iperf on a server in my LAN and ran iperf from my laptop connected to the cap lite.

TCP
[mikrotik@iperf1 ~]$ iperf -s -p 5201 -m

Server listening on TCP port 5201

<laptop> ))) <cap lite> - ethernet - <cisco switch> - ethernet - <hex, intervlan routing> - ethernet - <cisco switch> - ethernet - <kvm host> - linux bridge - <iperf vm, single core, 1024mb of ram>

I didn't do anything fancy and it "just works." Additionally, it's one of the cheapest APs available.

What are your wireless settings? I tested another cap lite this morning and at best it gave me 17 mbps. I've tried this and that, compared brands, I can't get the cap lites to break 25mbps. I'd love to figure this out!!

Remember, wireless is finicky. If you live in an area with high interference that can be a major problem. Additionally, the hardware you connect with can equally be at fault. It's not uncommon to see different wireless firmware or drivers behave differently.
