Slow WiFi (Mikrotik WAP)

SiByte · Thu Jul 06, 2017 11:50 pm

I have problem with very slow WiFi speed. I use Mikrotik WAP. I try lot of different settings but no change max speed is about 3MB/s from my NAS to device if I use wired connection I get over 100MB/s.

My reality

Before WAP I use cheap TP-Link for 10€ and I get much higher speed. Around 20-30MB/s or even more.

You likely need to provide more info, start with telling us what model of access point you are using and then how that connects to the rest of your network. You may also want to include the configuration from your access point (run /export compact hide-sensitive). To make it easier when you paste the configuration use the block quote in the editor here.

I stopped using Mikrotik for wifi as I've never gotten anything better than 25mbps (3MB/s) on 2.4Ghz. I switched to another brand for wifi APs and performance is better.
Lots of people have this issue and no solutions found yet.

I'm using Mikrotik WAP, WAP AP is connected to HP switch and directly to that switch is also connected NAS. So WAP and NAS are directly connected to same switch.

can u test transfer from a pc or laptop to NAS with wired connection.
i remember in the old days that some NAS network chip, speed u could achive was only 5mb/sec

SiByte · Fri Jul 07, 2017 5:33 pm

I use HP ProLiant Microserver Gen8 for NAS, and over wired connection I get around 110-120MB/s.

mistry7 · Fri Jul 07, 2017 11:40 pm

Please try Setting band=g/n
Is this Channel clear?

Prof13 · Sat Jul 08, 2017 1:32 pm

I have the similar issue with my cAP that is working as CAPsMAN's slave from RB2011.
Wi-Fi speed reaches 40 MB/s via RB2011 and 3 MB/s via cAP. Bandwidth test shows ~100 MB/s between the devices.

I will try g/n and only-n modes, and share results in a few days.

I'm using Mikrotik WAP, WAP AP is connected to HP switch and directly to that switch is also connected NAS. So WAP and NAS are directly connected to same switch.

I assume the wAP is not your Internet router.

There are several things that can be improved on your wAP configuration.

cAP and wAP are basic APs, conceived for serving as bare APs in high-density deployments. The better you optimize the config for their humble CPU, the better.

If this is serving just as an AP, try this config:

/interface bridge
add name=bridge1
/interface bridge port
add bridge=bridge1 interface=ether1
add bridge=bridge1 interface=wlan1
/interface bridge
set fast-forward=yes 0
/interface wireless
set [ find default-name=wlan1 ] band=2ghz-onlyn  \
    disabled=no frequency=2417 mode=ap-bridge ssid=Leutgeb_NET \
    wireless-protocol=802.11 wmm-support=enabled wps-mode=disabled
/interface wireless security-profiles
set [ find default=yes ] authentication-types=wpa2-psk mode=dynamic-keys \
    supplicant-identity=MikroTik
add authentication-types=wpa2-psk mode=dynamic-keys name=guest
/ip hotspot profile
set [ find default=yes ] html-directory=flash/hotspot
/ip dhcp-client
add comment=defconf dhcp-options=hostname,clientid disabled=no interface=bridge1
/system clock
set time-zone-name=Europe/Ljubljana
/system identity
set name=AP1

This programs the wAP to be essentially a wired/wireless "switch", which gets it's management IP from dhcp.

Is it advisable to create a static lease on your LAN router so that wAP always gets the same IP, though you could ever manage it without ip via mac-winbox or RoMON (i.e. without any IP addressing on the wAP).

No firewall, nor anything else, just an optimized config so that CPU requirements on the wAP are the minimum, the better, and everything is handled by hardware where possible.

DHCP to the wireless clients will be handled by your main Internet router.

Pay special attention to the devices Firmware (make sure Upgrade Firmware is the same as Upgrade Firmware @ System > Routerboard)

Hello Pukkita,
When I connect with the mobile the map lite shows a connection of 54 mb in tx and 72 mb in rx and I can not exceed more than 20 mb doing a test of speed.I tested it with a unify ac lite and with the Movistar router and the speed test shows 40mb more or less.
It is as if for the download the smartphone will connect in g and for the rise in n.
Has this ever happened to you with some Mikrotik ap?
I have tested with map lite, wap, hap lite and groove, but I always get the same result.

Yes I use WAP only as WiFi AP. I have upgraded both Firmware and Software,

I try your settings but no change, before WAP I use TP Link model TL-WR741ND (cheapest model) and I never have problems with speed. It has slower CPU speed and half the RAM of WAP so I really doubt that problem is in CPU.

- an export.
- a screenshot of wireless > Registration, open the phone entry, signal tab

I have noticed, specially on devices which were released with only one chain and were later upgraded to two chains, that the second chain1 sometimes is not enabled, watch out for that.

Map lite is a "personal" N device AP, there are two versions of it, one 1x1, latter models are 2x2. That could explain why half of the bw.

Unify Ac Lite is a different range AP, and it's AC, so is very possible you were using the 5GHz band. As ubnt doesn't publish Sensitivity specs but for speakers in their products, I cannot be 100% sure, but would say a more comparable (in hardware terms) product would be the hap AC lite.

That being said, if station is within range, it should be able to get speeds around 35Mbps TCP for 1x1 devices, and around 50-70Mbps for dual chain ones.

That's in N. Try forcing N mode only.

Hello again Pukkita:
I have tested with a low-end ZTE smartphone and I have not had any problems.
I performed the tests in 20 mhz. The connection shows 72 mbps in both tx and rx.
What I have observed is that this smartphone can also connect in 40 mhz. When I connect at 40 mhz the connection shows 150 mbps tx and 150 mbps rx.
I think the problem is in the smartphones that can only connect in 20 mhz. I have tried disabling g and leaving it alone as n, but the connection still shows me 54 mbps tx and 72 mbps rx. With this data I only get a speed of 20-25 mbps doing with speedtest. My smartphone is a low-end Huawey Yumo. I have also tested with wap and groove.

A greeting.

Prof13: which ROS/Firmware on CAPs and CAPsMAN?

All devices have RouterOS v6.39 and firmware v3.33.

There is a weirdness in cAP work: first speed test can show dl - 19.93MB, up - 4.91MB and second one that is made in 3 sec after the first one can show dl - 3.28MB, up - 3.91MB...

pukkita · Sun Jul 09, 2017 5:05 pm

Forget about the Air Rate, and 40MHz in 2.4GHz altogether... what counts is a stable connection, for that 20MHz is a must on 2.4GHz.

AirRate doesn't mean data will be actually flowing at those rates.

pukkita · Sun Jul 09, 2017 5:11 pm

Prof13: check your spectrum, and make optimal picks for channels for each cAP. In 2.4GHz there are only three non-overlapping in 20MHz channels: 1, 6 and 11.

To troubleshoot, you have too look at the signal screenshot I mentioned on my previous post while doing the transmission tests.

Sorry for the late reply.

I changed band mode to 2ghz-onlyn and it had no effect.
The freest channel was 3rd one, so I configured cAP with 2422 MHz with Ce extension.

pukkita · Thu Jul 27, 2017 12:45 pm

Why does Tx/Rx rate reach only1mb/6mb?...

it could be it actually isn't able to lock on higher modulations, please re-take the shots while passing traffic with bandwith test, ping speed or whatever.

From what you posted:

1.- Looks like your spectrum is really crowded
2.- Please double click on the registration tab entry, and shot the signal tab while passing traffic between them (e.g. by using bandwidth test between them).
3.- Looks they are using most basic G modulations, which could be explained by #1 (interference forces fallback to using basic rates)

I'm having the exact same issue, and it seems Pukitta is not able to provide any other help than the basic 1 2 3 guide to wifi problems.

* No channel congestion
* Cable from router to AP tested with another device, tested fine
* Another cable used to test, same result.
* B/G/N makes no difference
* Newest firmware/software
* Tested with various clients

Very low latency (30ms+), low speeds (1-2mbps), and I've come to the conclusion that this is just a low quality device that should now have been released to the market, and will be returning it next week and replacing it with a Ubiquiti.

Same problem here...but i replaced wAP AC with UAP-AC-PRO and my WiFi it's okay now.

Hello. Got a same problem. I'm use RB3011 as CAPsMAN controller and CAPac as AP. On 5GHz got maximum 13 Mbit/s download and 89 Mbit/s upload speed. If i use cable connection direct to RB3011, got about 90/90 Mbit/s... Distance between my laptop and CAPac about 150mm (yes, i'm try longer distance)...

Is there anything new? I have an RB3011 in two places as CAPsMAN with hAP ac and the WLAN speed is about 10% of what I should have.
Newest stabile RoutOS FW and HW FW on all Device.

Have you upgraded your CAP ac to the most newest one v6.43rc6? It includes significant speed improvement on WiFi of CAP ac and hAP ac^2.

Hammer · Mon May 07, 2018 8:08 pm

I saw the notice in another post, so it is an improvement there (not much time to test).
CAPsMAN and its products have been on the market for a long time, what's the problem?

luigim · Mon Jul 09, 2018 10:05 pm

I am having the same issue here. RB3011 as main router and CAP ac as AP. Very slow wireless speed. When I connect directly to 3011, I do get about 99mbs but wireless will only get 1~2. Anyone found a solution for this?

aschulze · Tue Jul 10, 2018 11:59 pm

The same problem here: 2011UiAS as CAPSManager and three hAP ac as CAPs.
All connected with 1GBit on a HP1820 Switch. On the ethernet ports I can transfer up to 108MB/s constantly. On WLAN I can transfer max. 1-2MB/s with strong fluctuations. This is terrible poor and unusable.

SilverNodashi · Thu Jan 10, 2019 11:54 am

I am having the same issue with a RB951Ui-2HnD, acting as "home AP. The wireless devices connect at 150Mbps yet they only get about 1Mbps internet speed on a 30Mbps fiber link. When plugging my laptop directly into the RB951Ui-2HnD LAN ports I get about 18Mbps download and 30Mbps (http://www.speedtest.net/result/7945325110) upload on speedtest.net. Yet, on wifi I only get about 3Mbps (http://www.speedtest.net/result/7944015867)

Does anyone know what could cause this?

flaiale · Thu Oct 17, 2019 6:03 pm

I noticed the association between the devices and the access point is pretty slow comparing to another wifi system ...is there a reason for that ?? And also is there a way to get back the 5Ghz signal after the 2,4Ghz ?? Any device normally connects to 5Ghz frequency when you are close to the router and switch to 2,4 Ghz when you are more far ...but after that it stays connect to 2,4 Ghz even if you are in fron of the router ...Is there a way to fix this issue ??

Your laptop won't change wifi access points unless the connection is broken. So when you leave the 5Ghz range, the connection is broken and it finds the 2.4Ghz wfii. When you come back, it'll stay on the 2.4. This is by design because if your laptop tries to switch APs, your apps will lose connectivity to their respective endpoints and will have to reconnect.

mkx · Wed Oct 23, 2019 1:26 pm

... if your laptop tries to switch APs, your apps will lose connectivity to their respective endpoints and will have to reconnect.

Not necessarily. If the other AP has same SSID and is member of same L2 network, laptop keeps its IP address and connections don't break, there's only a short delay (few seconds) during AP switch.

But yes, usual WiFi mobility is "drop snd reconnect" type of "mobility" ... there are apps (but disappearing as it seems) which try to force wireless client to use 5G AP if available. I've seen such apps for windows laptops and android gadgets ... sadly not recently.

Where is Normis? Where is MiroTik official answer to the problem? I think is a strange problem, what happens with every N chipset mikrotik device. Download can't better than 30 Mbps on every situation.
My problem is:
TP-LINK: 68,9/58,9Mbps
hAP lite / hAP mini: 31,6/76,9Mbps
Same location, same channel, same everything, but MT can't works well.
