I posted this on a different thread. Apple does not always play nice with other "N" routers. Just in case this information helps... I do know that the Apple.com site has stated at one point that they have known compatibility issues with "N" routers. I have accessed all RouterBoa...

Just an update. I dug my device out, updated to v5.17 and started using it. No reboots as of yet, but Skype or Dropbox use on one machine makes the network unusable elsewhere. Winbox or SSH won't connect to check usage. No new clients can connect via wifi. I'm going to try dropping to B/G, but that ...

phrozenpenguin

B/G didn't work for me either. Couldn't find any setting that would fix it.

phrozenpenguin

Thanks for the update. Glad its not just me.

phrozenpenguin

I tried various SNMP monitoring software. Became unresponsive as all other interfaces. Didn't use the Dude as I'm not a Windows user.

phrozenpenguin

Would be interested to hear how the Skype call goes - thats the only way I can replicate the 100% CPU and flash process. Downloading (even multiple legal torrents on a 100mbps fibre connection) works fine.

I think you need a 5ghz card to connect at anything over 130mbps to your Mac.

phrozenpenguin

I've got some different settings, but haven't been able to make a Skype call to check. Why do you have antenna-mode=txa-rxb and are you using an external antenna?

phrozenpenguin

I'm very close to forgetting this RB751U-2Hnd. Too much trouble with it.

Thats what I did. Now re-visiting and hoping things are fixed but it would appear not

phrozenpenguin

A default config still has the issue. Can you explain the queue settings more - I don't seem to have a bridge queue? [admin@MikroTik] /queue interface> print Flags: D - dynamic # INTERFACE QUEUE DEFAULT-QUEUE 0 ether1-gateway only-hardware-queue only-hardware-queue 1 ether2-master-local only-hardwar...

phrozenpenguin

Thanks. I will check out my setup when I get an opportunity. Here's hoping its just a simple mis-configuration on my end!

phrozenpenguin

Thanks. Please do keep us updated.

phrozenpenguin

How about the other two, if you have it? What is your /system package print output? I use Skype too with exactly the same routerboard and has no problem. I don't use either of the other packages. Do you use Skype over wireless? And do you use any Apple hardware? Would you mind posting your wireless...

phrozenpenguin

The 'ntp' package has this uncanny ability to restart Routerboards without warning. Those 3 packages I mentioned are usually not included in a standard RouterOS installation either.

Interesting. But I don't use the NTP package and still had problems.

phrozenpenguin

Disable the 'calea', 'ntp' and 'lcd' packages, and see if the NAND problem goes away. Especially the 'ntp' package.

Do you have any information about why the NTP package could cause a problem? And any advice for keeping accurate time without it?

phrozenpenguin

I've got .rif file and sent it to support. Waiting for response...

Do please keep us updated. I was spending so much time on this fault I just bought a separate wireless access point which worked fine.

phrozenpenguin

I'm currently using an RB750GL and was considering getting a RB751U-2HnD when I came across this thread. Has Mikrotik got back to any of you regarding this prob? I'm just afraid that I will end up with the same prob. They got back to me to say they couldn't reproduce the problem. I should try a dif...

phrozenpenguin

Please check interface queues since bridge-local is defauled to only-hardware-queue while it not supports it. I have changed it to default. Thanks for the input; I will test that over the weekend if I get a chance. I have ordered non-mikrotik hardware for the production install and am currently usi...

phrozenpenguin

I still have issues using a Macbook or Macbook Air and Skype. I have not been able to create a supout file.
This is a major barrier to me adopting Mikrotik across the business.

phrozenpenguin

I suggest you redo the tests but this time use a Macbook connected to the wired interface and one connected wireless for Skype. When the issue appears try to connect from the wired one by ssh or telnet and issue "system sup-output" from console or try to connect by using MAC address with ...

phrozenpenguin

I installed userman on the 751 fine. I can't remember the exact process, but I didn't do anything special and would likely have just followed the wiki...
Good luck.

phrozenpenguin

I have narrowed this down to the wireless interface and posted my findings here: http://forum.mikrotik.com/viewtopic.php ... 3&p=302265
I have tried both 12v and 24v PSU so I don't believe that is the issue.

phrozenpenguin

forces2010 - I am having a similar problem to you, which I have documented here - but basically when I use wifi and a skype call, I get high 'flash' usage, and I have not been able to get to the bottom of the issue.
I will be watching this thread with interest.

phrozenpenguin

I have been having some issues with my RB751u-2HnD, and have been doing some testing and narrowed it down to the wireless interface/wireless security settings. I have another thread about the issues here , but I wanted to ask the wireless experts. The issue is if I use Skype (video call) from a Macb...

phrozenpenguin

The Tools/Profile item may help locate what is causing the problem.

phrozenpenguin

I've had similar issues. I put it down to using Skype; but that could be just because thats about the only thing that might be taxing my wireless. I posted about my issues here: http://forum.mikrotik.com/viewtopic.php?f=13&t=58424 The next step is to try a netinstall and resetup and see if it st...

phrozenpenguin

I just did some more testing: - Running Winbox on Macbook connected to Wifi - Skype video conversation on Macbook Air connected to Wifi - Winbox profiler shows 'flash' process jumping to ~80% (CPU at 100%) - Winbox disconnects - Macbook and Android phone are not able to browse the web / Winbox will ...

I'm using PSU 12V, 1A (bundled with RB751U). In my network a lot of apple devices (MacBookAir, MacBook Pro, iPhone, iPad) and some Android based devices. Last time Skype was running on MacBook Air - wireless connection was used. Router establish l2tp connection with my ISP for internet access. Inte...

phrozenpenguin

lostar, sorry to hear you are having the same problem. I am being told to change the power adaptor - but I have tried three and it has not fixed the issue. What PSU are you using? Do you use wireless devices, and if so what? I use macbooks, iPad, iPhone and Android devices. I'm wondering if there is...

phrozenpenguin

I upgrade to latest firmware and routeros as above. I've upgraded to a 12v 2A PSU incase it was this. I have simplified my setup - a PPPoE WAN connection, DHCP server for ethernet and Wifi, SNMP for monitoring. I still have random reboots. When it comes back up my log file says: jan/02/1970 12:00:17...

phrozenpenguin

upgrade to RoutrerOS v5.12 and upgrade the bios to v2.38

I have now upgraded.

Do you have some eoip or pptp tunnels?

One PPTP VPN access for when I am offsite - rarely used.

phrozenpenguin

I have not been using this device much, but can confirm the issue still happens with the different 12v 1.25a PSU, so I do not think PSU draw is the issue. It doesn't hang doing anything else - including extensive down/up loading, considerably more machines etc. But just Skype on a single machine for...

phrozenpenguin

Current firmware is 2.36, and upgrade firmware is 2.37 - the change log only indicates a couple of unrelated things. Do you recommend I upgrade? Potentially useful - in System > Health, I get an empty box. uPNP was disabled by default, and I had the problem. I enabled it after reading that Skype wou...

phrozenpenguin

This is my one and only Mikrotik device - the first one I have ever used. I am trialling in at home in preparation for a deployment of 16+ and a 450G for work - but if I can't sort this than that deployment won't happen :-( I am using RouterOS 5.11, but have upgrade from 5.9 and 5.10 - all experienc...

phrozenpenguin

cbrown - thanks for the idea.

I was using the 24v 0.8amp that was supplied. I will try with a 12v 1.25amp I have and see if that improves things. I bought from a reputable reseller so would hope they were supplying decent power supplies.

If anyone else has other ideas please add them.

phrozenpenguin

I am using a RB751U-2HnD and have a problem where the router regularly restarts when using Skype from a machine on the LAN. I usually use Skype on a wireless connection from a Macbook. This is very frustrating but I must be doing something wrong as I cannot believe Mikrotik would fail at Skype! What...

phrozenpenguin

Please post the results of this test when it is complete if you don't mind. Thanks.

phrozenpenguin

I'm interested in this as well so look forward to other posts. Sorry I can't be of more help.

phrozenpenguin

janisk, thanks for the information.
Given I already have a RB751, I will test with that whilst doing some SNMP monitoring of the CPU load and see how I get on.

phrozenpenguin

Are there any more performance details available?

For example, according to http://mum.mikrotik.com/presentations/CZ09/tom.pdf, the RB1000 does over 900Mb/s.

Where would the MikroTik RouterBOARD RB450 fit in terms of performance?

phrozenpenguin

I kept going and managed to get the DHCP server to work. I had to add a network in IP > Address List on the ether 5 interface. I will leave the posts as I originally posted them in the hope that they help someone else. My question still stands - on ether5 I do not see a device plugged in: /interface...

I have a RB751u-2hnd, setup as default with some minor changes (e.g. PPPoE connection on WAN interface). Ether ports 2-5 are switched - but I want to remove port 5 from the switch group, so I can assign a separate DHCP server to this port (and then do more things). I changed the ether 5 master port ...

phrozenpenguin

I cant understand why anyone uses UM. MT clearly stated that they ended development. So this a clear signal to use something other.

Can you point me to where this is stated? Is there an alternative to run on a single device? Thanks

phrozenpenguin

Thanks for the advice. In terms of being underpowered- will that manifest itself as lower throughput (devices can still get online), or will it crash the mikrotik and no devices can access the internet?

phrozenpenguin

Hi all. I am relatively new to Mikrotik gear, but am very impressed so far. I need a router/firewall device for a new office - which will have internet via fibre which is presented as a PPPoE connection on a 100Mbps switch port (the speed limitation). I am hoping to use a RB751U-2HnD as the router/f...

phrozenpenguin

Many thanks. That worked, and now I will do some reading to fully understand SRC-NAT.

phrozenpenguin

I have updated the code blocks above; apologies for the error. I disabled the suggested action but still no access to 192.168.1.1.
I am assuming I will have to setup an explicit direction, but am not sure how.
Thanks for the assistance.

I'm pretty new to Mikrotik but all looking very powerful so far. My test setup is an ADSL modem > RB751U on ether1 utilising a PPPoE connection to connect to the ADSL. The ADSL modem has a status page (192.168.1.1) that I would like to access - it also acts as a DHCP server, and the RB751U gets an I...
