Hi mrz, i found out that it's BFD .. which is configurable but then i found some documents which shows that BFD is not yet implemented in v7?? Are you serious Mikrotik?? We can't got back to ROS6 with that CCR2004 because it tells me that minimum is 7.1.1 ... so the bought devices are useless for us...

brainy

Is the 5 GHz issue with RB4011 fixed ?

brainy

I've contacted MT Support also .. lets see what they say. I checked the supout.rif viewer and it shows "status: initializing" for wlan1 .. i guess it's maybe a driver problem (crashing or something like that)

brainy

Same here .. wlan1 is there but clients can't see SSID .. seems to be a common problem. Anyone contacted Mikrotik Support?

brainy

This post is nearly 5 years old .. i doubt they will ever implement it

We would need it also ...

brainy

Yes, they are stable. I also see this problem when i connect two CCR's with a direct cable.

Offical response from MT is: "do not use BFD, wait for RouterOS 7 where it is planned to be fixed"

But this is no solution for us

brainy

Anyone figured out how to work around this problem? We are trying to build a mpls network and some links are not stable 100% so we need a fast failover mechanism for ospf and bfd is the only solution. I dont want to set the regular ospf timers lower.

*) wireless - fixed AES encryption speed issues (upgrade suggested);
Care to elaborate? Which instance? Does this apply to ANY use of AES (WPA2 w/AES) with ANY prior version?

What were the problems?

Especially since when (what version and/or date)

brainy

Any news on this issue?

brainy

me too

brainy

rmichael, macgaiver is right:

24mil 64byte pps = =24mil*8*(64+ 14 (Ethernet header) + 4 (Ethernet trailer))/1000/1000 = 15,744Gbps
this is full speed full duplex - the limit is the port speed basically.

Is this also valid for firewall? Or just normal packet-forwarding?

brainy

What ROS Version? There have been a lot of changes in the nv2 protocol.

brainy

Anyone else with positive feedback?

brainy

Anyone updated to that test release and could tell us if this issue is fixed?

brainy

uldis, will it be enough to update the AP or does the client(s) need update aswell?

is there any workaround? this is REALLY annoying issue because its causing a lot of outages

Hi there,

someone has an idea what is causing this strange signal strengt?

LOS is ok, distance is ~250m One side is SXT, one side is OmniTIK (screenshot was made on the OmniTIK side) Both sides using "card-rates" with power set to 20 to prevent a too strong signal.

Regards,
Joerg

brainy

Try the following: Set rates to "configued" and check MCS only till 12 and do not use MCS 13, 14 and/or 15 .. this _will_ reduce bandwidth to 180Mbit/s air-rate .. but just test if this will fix the problems.

My colleague checked the antenna now and it is NOT dc grounded!

We will now try to use a Compex wlan card instead of the cm9 because we have a AP at another location which has exactly the same omni antenna (but with a Compex card) and it's working since 1/2 year without any problems.

I am talking about the onboard amplifier on the wlan-card.

Hi there, we have a 4-port miniPCI / PCI Adapter with four CM9 cards. Three of them running on 5GHz with sector-antennas. One is connected to a 2,4Ghz Omni. The one connected to the omni had a amplifier failure after 15 hours. We replaced it and the new card's amplifier failed also after about 15 ho...

Hi there,

i'm missing the possibility to add a defaultroute within PPPoE-Client to another Table instead of Main one.

Would it be possible to add this (really handy) feature to RouterOS?

Thanks

So where is this function to prevent this kind of flood? I installed rc10 on a testmachine and didnt find anything.

Hi there, we have a customer that has some kind of broken PPPoE-Client. The problem is, that his router is flooding our MT Box with several PPPoE-Login/Logout's Sessions. There are about 10 new Sessions per Second, resulting in 100% CPU usage and a lot of memory usage. Can i somehow add a delay in P...

Hello, we have the following setup: - Routerboard with RouterOS 2.9.46 - Internet Connectivity via eoip-tunnel - PPPoE Server on wlan Interface - A lot of simple Queues (matching Mangle Rules) We notice the following: One Customer hammered the PPPoE Server with a lot of Sessions, causing 100% CPU us...

Oh, is VPDN now supported on RouterOS?

Hi, i'm using the check-gateway function to check if my DSL line is up or not. But: If the line is full (i only got ADSL) the latency to the checked gateway is surely high. Now the RouterOS declares the Route as invalid since it wasn't able to get a reply. Maybe it would be a good idea to make the t...

Dear colleagues, i'm getting grey hair because i can't find the problem. I have a AP (Routerboard) connected to a 2Mbit/s leasedline. I have a PPTP Tunnel between the AP and us. We use a MTU of 1400 to be on the safe side. Everything is working but when i do pings from us to the AP via the PPTP Tunn...

Hi there, we just tried to install RouterOS on a 512MB CF Card. The netinstall utility finished the installation but the Router didnt boot. The SYSLINUX was startet and then we got a "boot failed" message. We tried two different 512MB Cards, two different PC's (from where we wrote the imag...

Hi there,

i just added a NAT rule with dst-nat and a time setting and it seems that it's ignoring the local Timezone for that time.

2.9.31 but nothing in changelog that would tell that this has been fixed

I doubt that you'll find a way to prevent users from changing their mac to access your service.

The only thing you can do is to use Encryption on the link and not give our the pre-shared Key(s).

I would choose the bigger line and do a bandwidth limitation per user. Load balancing is not always per-packet so maybe you can only have 512kbit/s on a single connection (TCP) when it's a load-balancing per source/destination. But maybe you get better redundancy with three single lines but you can ...

Hi there, we have a scenario with a PPPoE Server that uses a IP Pool to give out IP's for the Clients. The "problem" is that it should not give the Client the same Address every time but it should give another one. We're using this scenario for end users to give them a DSL like internet co...

We have a AP Bridge (Accesspoint).

We want to connect a station and simply bridge the ethernet to the wlan.

Or bridge two wlan interfaces.

"AP bridge" -> "Station" (WLAN1 -> WLAN2) -> Customer

So we can increase the range.

But it seems that this is not possible ...

Hi, why isnt it possible to use a Station as a Bridge between ether1 and wlan1? We need to increase the distance between the AP and some customers and thought about a simple bridge. As i read in the FAQ this is NOT possible??? Sorry, but i really don't understand why it does not work. We really need...
