Re: New CPU - new product RB750Gr3 - RB750G family - now mmips

There is a bit in the Wiki about this and you have to avoid packet fragmentation and the packet reordering is resolved in 6.39RC if I remember well.

http://wiki.mikrotik.com/wiki/Manual:IP ... imizations

On reordering:

http://forum.mikrotik.com/viewtopic.php ... ng#p576115
Thanks! I was unaware of the 6.39 changes. I've now upgraded both sides; I was already reducing the MTU. I have noticed that when only 1 packet per iperf test is affected by my MTU rules though; not sure if that should be the case. Unfortunately upgrading to 6.39 did not produce any changes. I've also tried reducing my firewall rules to the Mikrotik defaults (leaving the IPSEC and MTU rules in place) and disabling Fasttrack but still no change.

The reordering is not good interpretated by me. It is still present and the link I used was for PPP connections.

Thanks

Re: New CPU - new product RB750Gr3 - RB750G family - now mmips

I deployed a RB750Gr3 at a client with basic office NAT / DHCP / DNS and a queue tree for a 300mbps cable connection. After ~12 hours, the device stopped responding to ping. After a few minutes, pings came back but all usermode services appeared dead - no DNS, no winbox, nothing. Had to have the client reboot due to no DNS causing their internet to be effectively dead. After the reboot I had a window to upgrade the ROS and firmware (factory version was a couple of versions behind). Has anyone ever experienced anything like this before with this board? I made a big deal of how reliable a Mikrotik router would be over the current consumer stuff they were using and this is not a very good first impression :(.

You probably did not set a good password and the device was hacked, and the hacker started to play with it.
(press the upgrade firmware button etc)

Nothing was accessible from WAN.

Update: I seem to have been able to reproduce it by resetting the modem. The DHCP client got stuck in "rebinding", the IP on the routerboard remained active to pings and established connections, but new connections disappeared into the void (no hits on the firewall DROP rule). Maybe the shitty modem was blocking all WAN connections until it saw the IP was bound? Luckily I had an active SSH session that didn't timeout during the reboot, which is how I was able to diagnose this.

If you are going to store "The Dude" database on micro-sd...
... Cheap Junk Micro-SD cards you will likely wear it out very quickly
Further to this advice, can anyone advise what would be the minimum capacity microSD card to consider for a small home/office network?

I was looking at the high endurance cards and the 64GB should last just over 16 months if recording 24/7 at the rated spec, but maybe that's overkill for this? So I guess the question is really how much data can The Dude write?

16GB: 3,000 hours
32GB: 6,000 hours
64GB: 12,000 hours

Based on Full HD (1920x1080P) video content recorded at 26 Mbps at 30°C on Transcend DrivePro series. Performance may vary due to host hardware, software and usage.

endurance measures on gigabytes writen not hours

in my opinion is best to not trust that trascend specs

actually its measured in cycles of write for each cell.
transcend-wise they had both SLC ("industrial"-labaeled)products and bit more cheap "SuperMLC" which quite meh compared to SLC, yet bit better than MLC and TLC, but mostly in speed, resource increase quite marginal.
SLC tend to sustain 40x(or even 100x, depend sub-type or implementations, compared)bigger resource than MLC had, generally

endurance... ....trascend specs
If it was just a claim for hours use I wouldn't trust it and question under what conditions, but the last line of the previous post: "26 Mbps at 30°C" is the condition stated by Transcend. I would say that constant 30°C is very optimistic for dashcam users but you wouldn’t expect to be driving 24/7 either.

That is correct. There is no usermanager for the RB750Gr3.

I need to tie two networks together via Internet that both are not behind static IP. Since RouterOS is now past version 6.14, I think I can expect I will be able to use both MikroTik Cloud and OpenVPN to establish a bridge between two RB750Gr3, right?

Hello

missing user manager.
maybe for training or practicing is a missing feature, but for production environments is not, remember this device has level 4 license because that will be limited to only 20 concurrent usermanager sessions

if you have a remote usermanager you can use the rb750gr3 to do hotspot with 200 concurrent users, more than enough for this size of device

I ported U-Boot and LEDE (née OpenWrt) to this router
Hi, give me the link to the detailed guide or how to. Is it possible to do this without a spi programmer?

It's because you have the wireless package installed/enabled.

Remove/Disable it, reboot and will go away.

Because you might want to use CAPsMAN on the device? So it is actually not that funny.

You must to have other AP to use Capsman.

Yes. And then you can use the RB750Gr3 to manage it. And for that you need the wireless package. When you don't want it,
you can disable it. Just like MPLS (are you using that?), hotspot (only useful when you have an AP), and in many cases routing as well.
One nice property of RouterOS is that almost the same software is running on all the models, and you can customize it.
When you want to keep iterating that this is funny or strange, maybe it is not the ideal system for you.

it is perfect router to serve as CAPsMAN for a small home network (my case) or small office. As I use APs with reduced TX power to limit self-interference.

Unfortunately devices are shipped with the "bundle package" by default so this normally cannot be done unless you have done a custom netinstall - in which case you of course would have omitted that package.

No need to custom netinstall. Just put there selected packages of higher version and reboot.

Any date when userman will be available for Rb750gr3? Or no chances to get for this device?

Nice to know...so far I have NetInstalled all my routers to get rid of unneeded packages. :lol:
