Dear all, within a month there were three events that caused the network block of a client of mine. In the network there are 8 CRS125 and 20 RB951G which randomly stopped working. The error is "loading kernel from nand". I solved the problem using Netinstall to reinstall the operating syst...

I'm trying to define different user groups in User Manager to use inside the various server hotspot. For example: Radius: Group1: user1,user2,user3 Group2: user4,us...

Any reason why you want a 3G modem instead of a mPCIe? RouterOS supports the newer 3G/4G SW mPCIe module which support LTE interface. They also use less power and have better operating temperatures. I frequently use Mikrotik "integrated" solutions like RB951G, for example. This product li...

Thank you plisken. But I'm looking for a generic and unlocked 3G dongle to use with different provider available in my country: for example TIM, Wind, Vodafone, 3.

Hello, I'm looking for a compatible,cheap and fast 3G USB dongle to use with Mikrotik (for example with RB951G model). I already know Mikrotik supported hardware list [1] but I think is not exhaustive. What's your favorite 3G dongle? Does anyone used TP-LINK dongles [2]? Any suggestion is appreciate...

Hi all, recently I activated (my first) three SXT-G2HnD: one as access point and two as "client" (is CPE the right definition here?) using NV2 and I'm very satisfied. I've also a running RB751G configured as hotspot. I'm not able to configure this device as NV2 client of the SXT AP. Is it ...

What will be the listing price for CRS125-24G-IS-RM?

Thank you.

Hi all,

is there a way to use a Mikrotik routerboard as a L4 load balancer?

I'd like to balance, for example, a couple of web server and a couple of proxy server.

Any suggestions will be appreciated!
Thank you.

Mikrotik Support gave to me some suggestions: 1) unistall unused RouterOS packages to free memory 2) upgrade to RouterOS >= 6.0rc6: What's new in 6.0rc6 (2012-Dec-21 12:20): *) fixed problem - netinstall for x86 did not work; *) lcd - added take-screenshot command; *) lcd - fixed calibration, fresh ...

Hi all, when I think to a point to point link (2km), I'm very confused about some basic wifi topics: 1) what should I consider when choosing among vertical and horizontal polarization? 2) what should I consider when choosing among 2GHz and 5GHz devices? 3) and in general, what is a 2x2 MIMO device? ...

PSU replaced with 18V 1A but the issue is the same one.

Hi all, I use a RB751U-2HnD as home hotspot (firmware version 5.22). The routerboard works fine until I use a bit torrent client on my Linux laptop. In this case the Mikrotik reboots every time after a couple of minutes. In the Mikrotik log I didn't find anything of useful to understand the issue. T...

Sorry normis but I need further clarification:

If I enable chain1 the third internal (or MMCX external) antenna will be active: is it righ?
If yes, is the third antenna an improvment for my clients?

Best regards.

Hi all, I read the Mikrotik documentation about RB751 (http://routerboard.com/pdf/357/rb751U-2HnD-ug.pdf) and I've many doubts about the wireless section: Wireless device RB751U includes a 2GHz 802.11b/g/n wireless device built in. It has PIF type antennas (2.5dBi) built into the case, and one MMCX ...

Hi,

I read this interesting guide to protect my private network http://wiki.mikrotik.com/wiki/Bruteforc ... TP_%26_SSH) .

How can I view the timeout of each dynamic address-list entry?

Hi mrz, I'm sorry but I can't reset the routerboards because they're in production and my table is empty! If I have a RB2011 the test I would like to do is importing the attached configuration to try to reproduce the issue. The configuration is referred to a RB750G which has been burned by a lightni...

Dear all, last night I solved all my problems. I changed the default VLAN mode for interface eth6 from "fallback" to "disabled". Sincerly I don't know why eth6 was in fallback mode. I found the same configuration issue in a second different RB2011. I think it is a Mikrotik defaul...

Dear All, I've a trouble with my new RB2011L (ROS v. 5.19): it has 5 gigabit ethernet port and 5 fast ethernet port. All the ports are routed ports connected to different IP networks. DHCP server seems to be not active on eth6 interface. I think the problem could be caused by the fact eth6 is assign...

Hi all, I setup a Mikrotik hotspot. It works great but...how can I connect to each wifi clients attached to the hotspot from the inside network? Why?

Hi, I have an RB751U-2HnD which has a problem rebooting. The problem is that each time it tries to boot, it seems to go through its POST, and then all I get is a link light for ether1, the power light, and no other lights, and nothing works. My guess would be that it's stuck in the bootloader, and ...

I found an interesting and serious issue about wireless interface configuration on RB751U-2HnD. After every power cycle, the router stop the boot process due to the wifi network initialization failure (I believe): the green wifi led doesn't switch on. As side effect, the router eth1 interface is com...

If someone knows the pass phrase, wouldn't they just join the network and use other methods to sniff the traffic? If I correctly understood WPA/2 mechanism, the pass phrase should give access to the access point with unique encrypted stream for each client. Then users have to be authenticated by th...

Hi everybody. during the last day I did my first Mikrotik wifi experiences and I need your help to clarify some doubts.
