Same issue. Have you found the solution?

sstyle

That's the cause. Odd (although technically correct) behaviour of MT DHCP server is that it only returns options asked for. Other DHCP server implementations tend to include all standard options in offer and many DHCP clients tend to accept them. One of solutions would be to add to LAN another devi...

I know WHY! 1st device sent request to DHCP and he asked only for Router!: Jan/01/2002 01:01:02 dhcp,debug dhcp1 received request id 353977549 from 0.0.0.0 '' Jan/01/2002 01:01:02 dhcp,debug,packet flags = broadcast Jan/01/2002 01:01:02 dhcp,debug,packet ciaddr = 0.0.0.0 Jan/01/2002 01:01:02 dhcp,de...

Tried. PC and smartphone and 2/3 devices got network mask correctly. I think my goal is forward UDP request from 192.168.16.255 to 255.255.255.255 may be ARP and DNAT could help with it?

sstyle

Did some tests today. I think that there are two ways to make it work: 1) Fix situation when I send the UDP request to 19.168.16.255 and device does not answer me for some reason 2) Forward broadcast from 192.198.16.255 -> 255.255.255.255 (may be NAT could help?) Also FYI - there is 3 devices that c...

sstyle

Unfortunately I have no way to check network settings of this device (

Mikrotik connected directly, so there is no other DHCP (except APIPA)

I do not know how to check handshake of DHCP (

sstyle

As your device answers to packets targeting address 255.255.255.255 but doesn't answer to broadcasts sent to actual broadcast address 192.168.16.255 it seems like device actually uses subnet mask /0 It works even with request to 192.168.255.255, so mask is not /0. I think it is /16 instead of /24 t...

sstyle

My device has APIPA. So it can set ip automatically if connected device does not provide DHCP. But I see from DHCP leases that device get an IP from mikrotik DHCP. May be my DHCP server does not setup properly network mask for device and it stay 255.255.0.0? Or something else

sstyle

I did some tests, and now I'm stuck (( I ran an UDP Monitor on the smartphone and connected it to the Mikrotik by LAN (like my device). Then I sent UDP requests from PC and it works well. ... ... So, looks like DHCP works not correctly for my device or something else Or device receive request but do...

sstyle

Yeah, I tried to disable this options too, because it looks very logic, but did not help. So I think it is a bug (

sstyle

The PC does it right (uses broadcast MAC as destination), so either the Mikrotik bridge fails or the device ignores the packet.

Yep, something wrong. But as I said with two other routers - it works well.

sstyle

The AP with bridged interfaces only reacts on the MAC address, not on the IP address. (Unless .... "Use IP Firewall" is set in the bridge settings)

This option is disabled in bridge settings.

sstyle

Strange! (my answer was typed before I saw the last one from Sindy. It's the same answer but in other words) What is the subnet mask of the PC? If subnet mask is not /24 , then the MAC address used will be wrong. What is the MAC address used for 192.168.16.255? I am using 255.255.255.0 for all wire...

sstyle

Open a command line window on the Mikrotik, make it as wide as your screen allows, run /tool sniffer quick ip-address=192.168.16.255 in it and see whether, while you send the UDP from the PC, the "subnet broadcast" packets arrive via the WLAN interface and leave via any other interface. G...

sstyle

Try setting multicast-helper=full on wlan1 interface. It says multicast, but works for broadcasts just the same.

Tried, but still does not work

sstyle

I have a device, that conneted to Mikrotik by LAN and my PC connected by WiFi. I did a bridge LAN<->WLAN and setup DHCP. PC send UDP request to 192.168.16.255 : 192.168.16.107(PC) 192.168.16.255 UDP 48 60219 → 6500 Len=6 But there is no answer from my device! (This is my goal) BUT if PC did a UDP re...

And get overheating as result?!

Did it, but what should I do with ventilation holes?

sstyle

Guys, please add a new feature - completely disable all leds (power led can be enabled). It is very difficult to sleep with disco-light on the roof.

sstyle

Performance with RouterOS 6.37. It works nice for me.

It can be better (450Mbps+):

sstyle

What setup you have on the AP? 2.4ghz or 5ghz? Encryption or not?
Maybe you could send the support output file of the config to support@mikrotik.com so we could try to reproduce this problem?

Printer use 2.4Ghz, MacBook - 5Ghz. Encryption AES. Sure I can. Wait a moment.

upd: check your mailbox.

sstyle

Please tell us more detailed in what kind of setup the Apple devices are unstable? With 6.37 It needs more time to connect. When I open the lid of macbook I should wait about 1min. With 6.36 it is much faster. Also my printer by HP, when I connect it to 220V, it power on and shows on display that i...

sstyle

If you see multiple wireless packages after upgrade on your device then the spare one will disappear after next reboot.

Did you plan to restore cm2 packet? 6.37 very unstable with Apple devices

sstyle

Are you passing by any firewall filters? Try enabling fasttrack for that connection. Looks like it enabled. /ip firewall filter add action=fasttrack-connection chain=forward comment="defconf: fasttrack" \ connection-state=established,related add action=accept chain=forward comment="d...

I also have a lot of wireless issues with 6.37. MacBook and printer HP working worse. Wireless-cm2 was stable. How to downgrade to 6.36? Thanks.

upd: did it.

sstyle

I think you can disable all but power led.
Go to: System/LEDs

There is no settings for LAN ports

sstyle

oh, I see, did it. Did not help to increase a speed.
There is no settings for decrease tx-power another way. I asked about it here - http://forum.mikrotik.com/viewtopic.php?f=7&t=110316

sstyle

Is it possible to disable all leds? I see a disko-light on the wall (

I think 550Mbps over the wireless is pretty darn good. Remember the wireless specifications are a theoretical airspeed rate. Much like one cannot achieve 300Mbps over wireless N.

I use just a macbook pro 2015. It support 1300 AC. For example look at this: https://forum.openwrt.org/viewtopic.php?id=53703

sstyle

Did you find a solution? I am in same boat with you. Macbook pro 2015 and hap ac. maximum transfer speed is about 550Mbit\sec.

sstyle

It does for sure. You just need to have regulatory domain, your country and gain value set on wireless tab. on Tx power tab should be "default" mode. Then, changing the gain value changes the tx power. It cannot have any impact on the rx power, but you can regulate it on the second side a...

Looks like it does not help - #7 . Antenna gain does not affect on Tx/Rx Signal Strength. It is still -55-57dBm. So there is no way to reduce tx-power for 5Ghz?

sstyle

How to improove real speed transfer speed over 5Ghz? I See that Tx-power too high and I do not know how to reduce it. By RJ-45 cable I have a 100MB/sec real speed but by wifi 5Ghz only 330Mbit/sec.

Set group key update to 1h in security profile.

Tried. One hour is ok. But if I did not touch it for 1 hour it still takes a long time to connect

sstyle

Ok, thanks

sstyle

How to set right antenna gain? I have a hAP AC and there is zero value now. I tried to setup config for maximum performance, stability and coverage.

sstyle

Tried to set a correct tx-power. I read that Tx/Rx Signal Strength should be between -60...-70 for best perfomance. I tried to change a value to different with "all rates fixed" and I see that SNR drops down, but Tx/Rx Signal Strength not. It is still ~ -55dBm.

sstyle

Set group key update to 1h in security profile.

Thanks. I will try.

Little differences between 2.4 and 5 are normal since according to the documentation , but in your case probably difference comes from country regulations.

Performance with my Macbook pro 2015 = 1300 Mbit/sec:

But I hope it can be better, because I get this connection speed with stock settings (Changed channel width only, and country set to Taiwan)

sstyle

Found how to fix that. I have to set "Channel width" to 20/40/80. But then I see Ceee, eCee, eeCe, eeeC - but do not know what does it mean. And please teach me how to set power for maximum performance with Registration table

sstyle

Thanks.

sstyle

Sorry, I`m a newbie. Where is registration tab? Quick Set? And how to understand how much power I should set? I tried to set less power, but as result SNR does down in my bathroom. With maximum power it equals SNR from zyxel keenetic ultra.

sstyle

Hi, today I bought hAP AC. I have a Macbook Pro Early 2015. Connect it to 5Ghz network and once I have a 600mbps, but now 350-400 is maximum. Macbook 20cm away from router.
