Just a quick note. ROS 6.41 has drivers for support of 160Mhz AC channels. No mention of MU-MIMO. Looks like a direction towards 802.11ac Wave2. I don't think any of Mikrotik's current APs are Wave2 hardware yet.

Anyway this might be an indication of hw refreshes in the near future so if you're planning to get an AP, it might be a good idea to hold off for a bit.

Technically it's possible, if the router is writing something when you pull the power but I haven't had a problem yet. Of course, if you have a more complicated setup where the router is saving data to nand or usb frequently then it's essential to do a shutdown.

A quick test of the old RB750GL circa 2011 and UniFi 100mbps. Just to see if it can handle the speed.


ROS 6.41, 400MHz, default config + vlan500 + pppoe

CPU: 25-30% - Fasttrack On
CPU: 75-80% - Fasttrack Off

Not too bad for a 7-year old router.

October 2009 - RB750G
May 2011 - RB750GL
July 2015 - RB750Gr2
October 2016 - RB750Gr3

Soonwai,i had some question about changing the router for Mikrotik.
Is that really help with more stability of connection and better performance than normal consumer level's routers?
I am using ASUS AC66U,not the latest b1 version,but sometime the cpu usage is hitting above 90% with a bit more connection.
(Usage for home)

So how did you manage to hit 90% CPU load? I'm only able to hit like 70% when running multiple torrents on the exact same router.

Last month i just upgrade to 100mbps,and i use thunder(xunlei) download a torrent with 800++ connection and starting having connection issue,such as dns resolve failed on fb or some other page.

3 things to consider in a router, the OS, RAM and CPU. Just like a PC. Mikrotik's RouterOS, is very stable. You can throw torrents, vlans, qos, filters, etc.. at it and it just keeps on going.

Next is RAM, everything uses a bit of RAM. BitTorrent, as you know, opens a lot of connections so having enough RAM is crucial, pun intended. The RB750Gr3, for example, has 256MB which doesn't seem a lot but is plenty, even for hard core home use.

Looking at my router's connection list, it says it has space for another 472000 connections.

Next is the CPU which determines how much bandwidth it can route. 100mbps is easy peasy for the RB750Gr3 with or without hardware accelerated NAT. It'll also determine what else you can do with the router like vlans, firewalls, QoS, etc...

Having said that, with a simple config, the RT-AC66U should be able to handle 100mbps with no sweat. Just make sure you have hardware NAT acceleration turned on and that you're not using any features that automatically disables HW NAT. I believe QoS may do that but I'm not very familiar with Asus. What firmware are you using with yours?

I am using hardware accelerated nat,without that the router can easily use 100% with about 200-300 connections.
And i am using the latest firmware which was updated in last month.
I just curious about if i change the mikrotik's router, is that possible getting more stability and performance than that?

Hello sifu sifu. new mikrotik user here. got it after the lowyat forumers suggested this to me :D .

I got one question here, yesterday i tried rebooting my mikrotik but then it starts to constantly beep after that. hmmm.. cant connect to the internet as well. but managed to get it function again after i unplugged all the cables and put it back in..... why ahh?

I personally have not encountered that but have read about it in the Mikrotik forums. Don’t know why it happens. Just keep an eye on it. If it happens again then it might be signs of a hardware problem. Which model did you get?

try update your routerboard firmware, someone mention it resolve that issue.

Could be routerboot issue. Try upgrade the routerboot. If still cannot then you can try reinstall using netinstall. If that still doesn't work, then you might be unlucky and had bad nand. I had an RB2011 with such problem bad nand problem.

That's a different problem though, ethernet port flapping. I had this too but seems to be solved with 6.42rc.

Time internet international bandwidth is even worse than TM, but with mikrotik and a good QoS setup, everything worked flawlessly that while before only kb/s of bandwidth was used, now both gaming and video despite not using up all the bandwidth works well.

Tested from wifi with the most stressful test i could do and with high resolution bufferbloat.

Can you check you if there is packet loss issue with your connections (your other test results had high retransmit avg). I experienced packet loss issues before with both TM & TIME. A couple of times was due to fiber damaged, the rest probably due to their internal routing hw/link issue (only some ip range had intermittent packet loss). Even 1% packet loss will be too much especially the main use case for my company was for remote access (vpn/rdp/etc).

Below is the test from a server with 5GHz N usb wifi

I place little value on these benchmark results. Anyway, if you sure TM broadband will serve you better, get that instead & either keep the current TIME connection as backup/loadbalance or just terminate it.

Yeah i agree with RB750Gr3

Plenty of RAM :-)

However this one is my favourite

Ah crap this morning my 2 week mikrotik is failing me again. its not beeping now and the USR LED is blinking.. looks like its not rebooting as well because i cant go into the web interface.. when it first arrive, I did do a firmware upgrade before using it..

tonight planning to reinstall the firmware, hopefully will solve the problem:(

Wow! 36 core CCR, Running your pppoe concentrator on it?

I think you should contact the seller and get it replaced. Looks like a bad unit. Is it an RB750Gr3?

Yes it is a RB750Gr3. Just tried to reset, but cannot. its now beeping non-stop. using back my 5 years Asus n12hp.

So sorry to hear that. I've never had a single routerboard fail on me yet. Did you try a netinstall? If you don't know mind me asking, where did you buy it from?

With TM there was once a torn cable but that only caused loss of internet which was changed and fixed. The time internet isnt mine, only running my hardware but the retransmit was caused by a momentary packet loss that happens when you burden wifi. During the test i was pinging the router and it timed out only once because of wifi being suddenly loaded. Wifi has inconsistent pings when loaded so getting A+ requires not only a good WAN but also internal network.

But to get A+ on wifi is not easy. After TM was installed in another place i did a test both via wifi and wire using the provided hardware (tp link). Wire got C for both and wireless got F for both (on 5Ghz wifi AC).

My configuration is mikrotik as router, asus as wifi.
