Anyone having problems with SSH and ROS 7.3.1 on RB5009 or other devices?

Anything to do with SSH, eg: print, set strong crypto, regen host keys or import public key, results in error (2).

Found the problem. Here's how to replicate it.
(from "/system/reset-configuration no-defaults=yes")
1. /ip/ssh/set strong-crypto=yes
2. /ip/ssh/regenerate-host-key
3. reply n
(seems fine if Y to regenerate-host-key)

CODE
 MMM      MMM       KKK                          TTTTTTTTTTT      KKK
 MMMM    MMMM       KKK                          TTTTTTTTTTT      KKK

Bought 1 big heatsink and put under the RB5009. RM42
Temperature max is 41C. Just like got fan. Save the power consumption
on the fan. 24/7  passive cooling without fan.

How did you secure the heatsink to the unit? I am considering it as well. Mine's hovering at about 47Deg. biggrin.gif

The heat sink is huge. Just place the rb5009 on top the heatsink

Good idea. Mine is 47c idle. Room temp 28c. But CPU temp like didn't go up when usage around 38%. I only used TM Speedtest to test.

My RB5009 is mounted on a long piece of wood on the wall so only about 50% of the router's back is flushed against the wood. The rest of it is 2cm from the wall.

Now I put 1-meter metal ruler against back of the router. Temp drop to 45c.

You guys got use Queue(QoS) or only enable fasttrack only for unifi/maxis?

I trying to setup queue but the result still not satisficed , running max download speed still affected latency...
Bufferbloat test keep giving A only,still unable to get A+

I thought bridge mode btu does not affect performance?
I also want to change the btu,because i think this btu got some problem,but i not sure is my area issue or not,
Sometime the rj11 phone will suddenly drop the call while using the phone. (And i having this issue about 6-7 years ao since from my previous home with the same btu and nearby resident area-different taman)

Still setting up the RB5009 so min config at the moment. Basic firewall, no queues, Fasttrack is off, bridge VLAN filtering is on for 500, 600, 50 (my LAN) and 50+600 trunk to downstairs.

You use waveform to test? I alternate between A or A+.

Ya waveform,i think yours download speed not running full speed so the latency not affected,mine during test totally eat 800+mbps dl and 200mbps+ up speed,so the latency is affected.
Later I try to limit my speed to see got difference or not.

Dont know use what reason the force them to replace...Since I cant pretend btu broken without btu off...
So nvm la,just wait for a few more years when they introduce higher plan then at that time btu must be change.

This waveform test, can select server? I keep getting 200-300Mbps only.

Tried again got 760Mbps but upload 50Mbps.

I think nope,seems like your unifi ip range not getting stable routing to the server.

And i just tried simple queue with 90% speed limit - 750M and 180M ,and the result is good.

hi all sifus,

I finished setup my hAP ac router to connect to TM Unifi by following guide from website.

now, i want to setup multiple VLAN, such as my kids connect to vlan01, my IoT to connect to vlan02, and myself connect to vlan03.

i am afraid to mess around with the router.. any good guide i can follow?
thanks

If you're planning to setup VLAN, I only have 3 advices to give -
1- export your configuration regularly.
2- make sure you know how to reset your router.
3- Leave yourself a backdoor (designate a network port for emergency use).

I made a mistake earlier changing some VLAN settings and locked myself out of the router, as my PC does not support VLAN tagging. I had to do a hard reset.

PS, both Realtek and Intel NIC's support VLAN Tagging

For Realtek, download Realtek Ethernet Diagnostic Utility, there are VLAN options in there
For Intel, download Intel ANS (Advanced Network Services), the VLAN options will be in device manager tabs

Finally Mikrotik adds 802.11r (fast transition) to wifiwave2 in latest Routeros 7.4 beta5. Still no sign of k or v.

...and still no Capsman for wifiwave2. Hopefully they can add it before Russia invades Latvia.

Also Docker is back.

Once upon a time I embarked on my vlan adventure with just the docs on wiki.mikrotik.com, a few Youtube tutorials and a post on klseet.com. (can find it here: https://forum.lowyat.net/index.php?showtopi...ost&p=87871705) This one too: https://forum.lowyat.net/topic/1733801/all

In fact that's how I got hooked onto Mikrotik, because I needed something that trunked vlan600(HyppTV) and my LAN from upstairs to downstairs. Shortsightedness resulted in yours truly having just one ethernet cable from the router to the living room TV.

Since you have everything working now, just save a router backup. Worst case, do a reset and restore the backup. As someone has mentioned before this, leave your one of your ethernet ports out of the bridge and vlans so you can always use that to go back in.

I'm thinking to replace my existing router that started to show some age now. And here I am hoping that you guys can shed some opinion here whether Mikrotik suits me or not as I understand it has lots of features with steep learning curve and I am exploring my options.

I don't consider myself as advance user but I only know enough to get myself through any typical consumer grade routers. What I'm looking for is stable network throughout the house with up to 7-8 devices connected including gaming desktop which I am hooking up via ethernet currently.

I don't think I will need any other features as I don't know how to use them most of the time.

What I have in my mind right now is hAP ac2 or ac3 to pair with mesh wifi system. So, would you guys still advice someone like me to still go with Mikrotik? To be honest, I don't mind a little tinkering to get it work though.

If you care about stability, most modern consumer routers are really good these days.

The hAP ac2 and ac3 are not fast either. Most mid-range WiFi 6 routers have a much faster CPU with much better NAT performance.

Unless you love to tinker around, getting a typical consumer router is more practical.
