I am having the same issue on a 6.40.6 RB2011. Previously working Windows 10 VPN, stopped working. I have not changed ROS version, but client Windows version has probably updated.

I suspect that there's been a deprecated cipher causing a problem.

There is no resolution, and not a peep from Mikrotik. You must use a clear text password if you want to use RADIUS.

He doesn't have Mikrotik at both ends of the tunnel yet, and not all tunnels are slated to have Mikrotik at both ends.

There should be a way to relay the traffic over the IPSec tunnel, if the Netgear can do it I can't believe that there's no way to make a Mikrotik do it!

If you use different channels, and don't use WDS, doesn't this mean the client has to drop association with the first radio card before it can associate with another?

UDP tests are deceptive, as most real world traffic is TCP. Doing a TCP test to your AP will give you some indication of what actual capacity is, but going *through* the router not *to* the router is the best way to test. e.g. < Btest on PC >---- <RB> --- <RB> ---- < Btest on PC >

You will end up with CSMA problems if you use the same frequency on all sectors. Use non-overlapping channels for best results. In the USA that's 2412MHz, 2437Mhz, and 2462Mhz. If you use the same SSID you can have clients choosing which antenna is the best e.g. "Roaming". For best results...

nickb

Then it probably wasn't CSMA.

Maybe just having the carrier active increases your BER, thus reducing the modulation rates (which is in turn reducing your TCP throughput).

nickb

Looks like CSMA in action to me.

nickb

Also make sure you are running at _least_ 80Mhz of channel separation for running cards in the same board. I find that adjacent channels don't work at all, and one or two channels away still gets some interference depending on the transceivers.

I think this problem is best explained as poor design in the RB433. Many people didn't have such problems with RB532 because one card on each side and they were not directly behind each other.

Has anyone made this successfully work with Cisco IOS as the PPPoE server?

I would very much like to provide 'bonded dsl' service over multiple DSL links, but I have not been able to successfully configure my Cisco router to accept multiple PPPoE sessions.

My advice would be to try to get the telco to deliver the service to you on ethernet. PCI DS3 cards aren't very common and tend to only be supported by one particular piece of software. I don't know of anything with an OSS driver. Re: just use the cisco as transport to the mikrotik - the problem wit...

So when creating the parent queue queue is that under queue-tree? would I use global-total, or do I have to make one for each direction? Do I need to use packet marks?

Greetings, I've mostly only used simple queues, so I'm curious if there's a better way to set up the queuing for this scenario in a way that would possibly allow for better distribution of bandwidth and avoid a contention situation.

The user-manager seems quite great - if you want to take money. However, what I would like to do is provide a "Free" hotspot, using all of the features of usermanager/hotspot. What I mean is rather than having an open AP that someone can just hook up to, DHCP, and go, I want to have an AP ...

As little as 6dB SNR will work for 2.4Ghz B-mode operation, but it won't work very well. 15dB+ is ideal.

Mikrotik,

Please SEED your torrents, especially on release day!

It doesn't do any good to offer download via torrent if you don't seed it!

Now it's working!

I got the notify email about 3.11 being released, and immediately joined the torrent. However, There are about 100 peers and no seeds?

I'm not seeing any traffic, either direction.

Did Mikrotik accidentally filter out p2p on their edge router?

nickb

I can't speak to the CCQ levels but I can tell you that it is completely normal and by design that any card with an Atheros chipset will idle at the lowest modulation (i.e. 6Mbps) when no traffic is present.

Linking over water is a huge pain in the ass, if you ask me. The root of the issue is that water surfaces function as an RF mirror at these frequencies.

That'll work fine on the AP side, but not on the client side. As you can't add an client mode interface to a bridge group. You'll need to use WDS to make it a "real bridge". What I do is set up the ap/bridge as normal, but then enable static WDS and dump the wds interface into the bridge g...

Yes, you can reduce prism TX power; it just has to be done from the terminal window.

See my last reply in this threat.

I have used this method in production since then several times, successfully reducing power levels for short links.

I don't understand why Mikrotik designed this to use 5.5v, when 12v is much, much, much more commonly available.

To answer my own question - it's probably because the on board power supply doesn't output 12v, because they don't need it for any components. That's just conjecture, but it makes sense.

nickb

Use a 12volt fan! It will work, just spin slower. No, it won't. I tried four different 12v CPU fans; one of which was brand new out of the package. EDIT: I think I've put my foot in my mouth here. I dug out another fan, 12v without tach, and set manual for the port it's on. I'm getting fan action a...

Indeed. I am having trouble locating a suitable fan.

I don't understand why Mikrotik designed this to use 5.5v, when 12v is much, much, much more commonly available.

You can probably accomplish this with scripts, but it would probably be quite complex.

nickb

My rule of thumb is "30-40 clients per radio". In otherwords, when I get to 30, I start planning for transitioning from omnidirectional to multiple sectors for the site and implement it when the site gets above 35 clients on the omni. If you have lower bandwidth profiles and no p2p abusers...

nickb

I disable WWW on all of my units, mostly to prevent botnet scanners from finding them. That also has the benefit of "hiding" the router from customers.

nickb

Turn off "forwarding" on the wireless side; such as disable "default forward" if you have are using "default authenticate", or uncheck "Forwarding" in the access list entry for a MAC address. This will prevent DHCP from broadcasting to other wireless clients.

nickb

One way to accomplish this is to put all MAC addresses into the ACL then comment the ACL entries. Then, the mac addresses in the ACL with comments will show up in the registration table with their comments.

nickb

I had the same problem as your newest post, which I resolved by check marking "Bootp support" in the definition of the DHCP server. My DHCP server is Miktorik ROS as well. I'm not sure how to set that up in another type of DHCP server.

nickb

I would argue that this falls under network management, as allowing IPTV would degrade the service of all customers on the wireless cell. Similar to how allowing P2P protocols degrades service. "Neutrality" or not, I have to make sure my customers receive a good quality service. If blockin...

nickb

Is there a way to specifically DENY any and all IPTV traffic? I know it probably wouldn't work anyways without extra effort (if my forum searches are a good indicator), but I want to make sure that it is firmly firewalled off.

nickb

Set your cards to B-Only mode, and it will probably work much better.

nickb

I used to use amps too, and I can tell you from my experiance, don't use them.

Amplifiers aren't too bad with PRISM or HERMES based cards, but I have never had one work worth a piss on any Atheros based cards.

nickb

High wind probably caused a static charge that blew out your transmitter. I've had this happen once or twice - some people have had it happen many dozens of times. It depends on your installation methodology and atmospheric conditions in your area. Basically, when I've seen this, the card can hear j...

First off - please find your caps lock next to the A button and press it. I have seen this kind of symptoms before. Sometimes switching to B-only mode will fix it.

At that distance why don't you just simply use lower gain antennas to reduce your received signals? 29dBi seems like it's quite excessive for that distance. I'd go with something more in the 15-19dB range.

We have customers as far as 15 miles or so from 130-150 foot AP sites, with 26dBm CPE using 24dBi antennas.

nickb

I use a mix of XR2, SR2, and R52H. We are a rural wisp, so the higher power is necessary to reach customers as far as 18 miles from the AP. For CPE we have been using Senao CB3+ for many years, with very good results; but I have been told that it is being EOL'd by Senao, so we are currently investig...

According to wikipedia:

U-NII 2: 5.47-5.725 GHz. Both outdoor and indoor use, subject to Dynamic Frequency Selection
