As time goes on, the performance of the machine declines. When it is restarted, it can run more than 400 megabytes. At this time, a CPU takes up 100. After 2 to 3 days, it can only run about 250. At this time, a CPU takes up 100. The machine is rb450gx4.

1) you have rebooted? Of course. 2) full reset the config And I will lose connection to the router. No, I'd rather be with the old version of the software . If the new version doesn't have the features you need, or if the old version doesn't have problems affecting your use, you don't need to upgra...

remember: start with the minimal package set, and then add the needed ones later. How more minimal? 6 MB package, 6,6 MB (3%) flash free, but still "not enough space for upgrade" # jun/ 3/2021 10:56:53 by RouterOS 6.47.9 # software id = I13V-2G3X # 10:53:13 system,info installed system-6....

My new RB1100x4 hung twice in last week. I had to make factory reset to return it to life both times

Does anyone have RB1100x4 working stable with this version?

yes，it works fine...

shiyiqiang08

You can filter out YouTube DNS

shiyiqiang08

You should be talking about environment variables. It seems that ROS does not provide this function.

shiyiqiang08

I don't know why, there are so many problems with the new version, so if the current version is OK, don't upgrade it. I think they have changed a group of people. The new software is too unstable.

shiyiqiang08

I think the most important thing is stability. As for others, they are still acceptable. The latest version is not stable. In my impression, the previous version is very stable.

Is your power source original? Not enough power？

i forgot my password so i try to reset it with reset button but it does not work what can i do If you still can't reset your device using information from our WiKi: https://wiki.mikrotik.com/wiki/Manual:Reset Please try to Netinstall the device: https://wiki.mikrotik.com/wiki/Manual:Netinstall mayb...

shiyiqiang08

You can use a jumper on the board itself
.
This image is only an example

it does not work
i have try many ways,still can't reset

shiyiqiang08

maybe Protected bootloader,
what can i do

shiyiqiang08

i forgot my password
so i try to reset it with reset button
but it does not work
what can i do

shiyiqiang08

you can use udp to test it
in some situation ,tcp has some problem .

shiyiqiang08

can i use testing version for daily work？
what is the main difference between them .

shiyiqiang08

you can use packet sniff to see what it is
or you can use wireshark on pc to see what it is
it is strange ,udp often have it's port

shiyiqiang08

Maybe someone from Mikrotik team can explain this situation? Hello!!!

maybe our phone does not support 160mhz.....

After updating RouterOS to version 6.43.7, part of computers in the LAN can't ping each other.Is there the problem with this version?

Did you close the windows firewall?
if not ， you can't ping it

I am trying to login to a mikrotik router using winbox v3.18 however it is stuck in logging in.

I can login successfully using the http.

Any ideas? already tried rebooting the router

Router version V6.33.3

you can try to clear cache of the winbox

I know what it is supposed to do, and I want it to do that. What I am trying to understand is HOW watchdog reboots the system. Does it go thru a real reboot, or does it just power down the device.

Hello. My first post here. I recently got a Mikrotik cloud switch series router. It was a gift and now configuring it properly is giving me issues.

And so starts the chaise . External source (under "attack") or internal (ex broadcast storm or loop in network)?

yes
i check it
but it is not ,everything is ok
i have another router rb931 ,it has the same problem ,i am so confused ,maybe some packets cause it ,6.42.9 is fine.

shiyiqiang08

what did cpu profiler tell you? were was that 100% load coming from?

network and firewall

shiyiqiang08

when i upgrade my rb3011 to 6.42.10(long-term)
after 5 days the cpu usage get 100%
after i reboot it .it is the same
when i downgrade to 6.42.9
everything is ok
why?

shiyiqiang08

I don't see that setting, are you sure it is available in ESXi 6.0.0? i am not sure,but you can check it online.i use the Virtualbox, when i use virto-net ,the cpu usage reduce 20%. It's a virtualization technology. General virtual machines have this function It can significantly improve network pe...

I noticed that hAP ac² reboots significantly longer after update than CCR1009 or RB2011. Is it because of 16mb flash thing?

i guess
maybe the cause of it's wireless module

Hi guys, I am new to this forum, I was wondering if anyone got better performance by disabling hyper threading. I will need to take down production routers to do this.

shiyiqiang08

i also have the same problem
when i use rb3011 to download and upload
when the throughput is 100m/100m
one of the cpu is very high
maybe it's the cpu's problem,the cpu is arm

you can use /ip route rule to add rules
it can assign priority to each rule so you can make on you own idea

Does Winbox encrypt the traffic sent from WinBox to the Router?

No, it is not a bug. It is actually mentioned somewhere in the wiki. Fasttrack bypasses some sections of the Firewall engine (part of which is mangle) and this makes it incompatible with some features that look inside packets, like pcc (which is based on source/destination addresses/ports). thank y...

Hi

By design: fasttrack bypasses mangle rules which are needed for pcc to work.

thanks
so the fasttrack is not usefull
because it has so much restrictions

PCC requires mangle and connection tracking to work. Fast track removes all connection tracking in an effort to process packets faster. No bug.
