New AC Board as a Client in a 11n net

Hello, I have a link with four stations and 20 mhz/5Ghz under 11n. It runs great (up to 40 km and up to 40 MB/TCP). When I connect one Rb911ac-Board (11n Mode only as a station bridge, no traffic) to the link, the link of the same stations become unstable and the speed goes down and as well the ccq....

Re: 60MHz channel under ROS 6

60 Mhz ? Do I miss something? I just installed ROS6 on a 493GAH with a R52n. But I do not get a 30 mhz width. I only see channel-widht and the max is 20/40 below or above.

Chadd I have the same error and already a ticket at MT. But I get a crash when I switch in Bridge from RSTP to None. And I do not get a suppout. Do you ha...

Re: RB433AH(800MHz) vs RB600(400MHz) thruput on PtP and Nstr

I tested RB600 and RB433Ah and a wrap Board with 500 MHz as well. The best performance was with the WARP Board, followed by the RB433Ah and than comes the RB600. Ok, it has a GB port but if I test the 1 GB port with Btest I get not more than 60-70 Mbit in half duplex. So for what do I need a 1 GB P...

and you can not put two antennas with opposite polarizations? vertical and horizontal sectorial? Not sure about that, correct me but if you use the same polarity same frequency (vertical + vertical or horizontal + horizontal) in close proximity then you can have phase cancellation, and maximum happ...

40 Mhz while using 802.11n

Hello, how do I force MT to use 40 Mhz channelwidht in 802.11n only ? I have the strange behavoir, that MSC4 brings 81 Mps. If I activte MCS-5, it stays at 26/39 Mps. I use "channel above control". Version is 4.11, both side RB411AH and Mars 25 dbi dual polarity and chain 0/chain 1. Nstreme dynamic ...

I think it will bring 6 db more, if the antennas are correct justated....

Re: What are you going to replace now?

I agree with you. With the new Atheros CPU (300 and 680 mhz) I can do almost everything I need. I am a WISP as well and have hundreds of boards in usw. The 532 was/is stable, thats right but in the past I had very often problems with the performance (I swap the 532 time after time) which I don´t hav...

Hello, I have 2 x 433AH as well. They don´t even boot properly with 800 Mhz. All I get is a system dump at startup. And belive me, the CPU is cold. I set them to 600 Mhz and thery work fine, but I have one 411AH and this one hangs up every time when I want to scan with the Wireless-Cards. I will cha...

Re: rebooting for (cause 1)

I have the same problem with RB333. It seems to me that the mix of 2.9.51 and 3.10 and EOIP. I change the other End of the EOIP to 3.10 and the problem disappears. In an other case it does not work. In this case I changed the end of the EOIP to an other board and the problem was gone. Today I had it...

Re: RB133c and 3.10b

Sometime patience helps. I waited longer (30 Minutes) and removed the WLAN Card, enable only routerOS, Routerboard security system and wireless and it boots with 3.0 Beta 10. Sorry, if I "produced" a little work with that. Hopefully I am able to reset the on-the-roof-already-installed-antenna with c...

Hello, I just updated two RB133c with Level 4 to V3Beta10. Now the boards boots, send the post-screen on the Hyperterminal, beeps one time, ask for the User/Password, send the Mikrotik Logo and thats it. Completly hang up until I repower the board and everthing started again. If you scan via Winbox,...

This is already under invertigation with Mikrotik. The problem is not a Mikrotik-problem in special. I have expierience with WPA-PSK. This happend often.
