Hi guys, I have a DHCP server and a 192.168.0.0 network issue and I would appreciate any help. My network, as seen in the attached file, consists of two RB411 connected in a point to point bridged network providing internet access to wired PCs. All he IP addresses used are public and so far everythi...

IMHO you should downgrade the firmware separately before going for Ros downgrade...

http://wiki.mikrotik.com/wiki/Manual:Bootloader_upgrade

after firmware file transfer with xmodem Run command /system routerboard downgrade
Reboot your router to apply the downgrade (/system reboot)]

Can you downgrade 6.0 to 5.25 using xmodem? I tried by interupting the boot, sent the upgrade package for 5.25 over xmodem but it complained about invalid upgrade id or similar. You should be able to downgrade with hyperterm. I'd recommend 5.24 not 5.25... I had a similar issue (Ethernet flopping )...

If it ain't broke don't fix it... I was fine with 5.24 on my P2P 411s until updated to 5.25. Connection was lost frequently and there was a message like "too long to be polled..." or something.. Downgraded to 5.24 and everything came back right. It looks like it was another "non-deter...

Update: It looks like Teamspeak as well as some other traffic were just triggering the port flap. The problem was firmware 2.29 that I had so far. Took the router down replaced old 560 μF capacitors with new 680μF and updated to firmware 2.41. Note that I took the risk of updating to RB411's 2.41 wh...

Try to upgrade your RB411A as described in Wiki article: http://wiki.mikrotik.com/wiki/Bootloader_upgrade In Winbox 'System/Routerboard' you should see latest available firmware for your RB. HTH, This is what I exactly did to get rid of 2.29. Yet, latest version in routerboard site for RB411A is 2....

Can someone please tell me what in the hell is going on with with RB firmware ? I've got one RB411A and one RB411 on a P2P setup. RB411 firmware running version 2.41 routerboard site 2.41... so far so good. RB411A firmware running version 2.29 routerboard site 2.20!!! where did I get the 2.29 from? ...

lol for sure but, I'm not going to try reproducing the problem cause is very fckng annoying. Fact is that I never had the problem' it appeared when teamspeak 3 was installed and disappeared after uninstalling.... coincidence? maybe... No time to go deeper but, what happens if teamspeak, while stream...

As I posted to another thread, teamspeak triggered the eth problem on my case...

I had the same problem on my RB411. It just appeared a few days ago after 3 years of normal (Ethernet at list) operation. After some research I discovered that the problem was triggered by teamspeak (http://www.teamspeak.com) installed on a pc by my son (I have a P2P connection). From what I underst...

No, it is just the name http://www.calamp.com/products/mmds-transceivers/parabolic-antenna-assemblys/parabolic-antennas The only thing is that the antennas are "QLP" (Quasi Log Periodic) which I'm not sure of what this stands for. The fact is that they have an outstanding performance with ...

Just for the history, I used to have an Aironet BR500 hooked up on one side and Aironet UC4800 11mbps on the other. Their performance was excellent on those antennas. I had to abandon them to increase throughput and number of PCs networked (UC4800 supported only one PC) . I've been straggling ever s...

I discovered that my antennas -that I bought and installed a long time ago- are California Amplifier 24 dBi QLPP Parabolic Antennas!! similar to this but 24db california_amp-2.jpg http://www.calamp.com/products/mmds-transceivers/parabolic-antenna-assemblys/parabolic-antennas their range is 2150 - 27...

Here is some more Is it the best channel you found? What antenna exacly are installed on this link? You have to strong signals. Lower tx power on both sidesw for 3-4 steps. Increase Hw-retries to 10. What cards are you using? I think this cards are 2 chains cars, so can support 802.11N standard. Se...

RB411A has an AP license, it's not a CPE unit.

that figures..

I've got one RB411 and one RB411A (level 4).
Quickset exists only on RB411 !!! Isn't 411A a 411?

P.S. Probably an " OR 411A" on hardware check is missing...

Thanks for the reply
I'll do that and see what happens..

Hello to everyone, I'm trying to solve the following strange connection problem with my Mikrotiks and any help or idea would be appreciated. I'm trying to establish a connection between two points 4km appart from each other. On one side I have a RB411/R52H (350mW) that was previously connecting to a...

Thanks.

Since I haven't got any replies in my previous post, I decided to provide a "before" and "after" of what I'm trying to configure. I want to remind that Cisco 1310 cannot be replaced and that Cisco wireless products cannot operate as Bridges without the proprietary Aironet extenti...
