MikroTik

chucka

Mikrotik,

Please look at quantity packaging for the LHG. A 5 pack would be great. A 10 pack even better, if possible... We are filling up our dumpster with the packaging from these and shipping is a little high because they ship individually to us from our supplier.

Thanks.

chucka

Oops, I actually meant a 32 dB dish and yes, it is a new backhaul to a fiber connection at that location. It will probably be upgraded to a licensed link eventually.

Thanks for your input.

chucka

This isn't really a Mikrotik related question but it does pertain to our 100% Mikrotik network with over 900 clients. :-) I have not used a commercial tower provider in years but needed access to an AMT tower for a new backhaul project. The tower is in Texas near an Interstate and does have quite a ...

chucka

I would just use a Mikrotik device with a directional antenna and run the wireless snooper, look for the mac. Go foxhunting!

chucka

we will try to find some similar aged boards. Please write with the serial number (or mac address) for board so that we can find one made around the same time and test. I was not able to repeat the problem on any other 433AH boards that I had. I tested 4 other boards, one with a very similar serial...

chucka

UPDATE:

I have upgraded several more 433AH that I have as spares. One board is from the same serial number batch. They all upgraded from 2.20 to 3.02 with no issues. Since I have not been able to repeat the problem, I would say this is just an isolated incident with a bad 433AH board.

chucka

Thanks for the reply. I'll try that on this board. I've upgraded it several times and it is dead until a hard reset every time. Is your problem only with the 433AH boards like mine? I've upgraded probably 150 of our 411 clients out there recently with not one problem. Upgrading from every version im...

chucka

I upgraded one of our towers early this morning from 3.30 to 5.23. This upgrade went fine and I decided to upgrade the firmware from 2.20 to 3.02. The tower never came back up after the reboot. A couple of hours later we were onsite and replaced the board. I expected to see drooling capacitors on th...

chucka

Just downloaded version 6.0rc6 in hopes that torch would finally have the port column added back. Unfortunately we still cannot sort by port number. :-( This is a very handy feature for hunting down bots or virus infected machines on our customers connections. I haven't seen much in the forum about ...

chucka

Don't NAT until you get to the the 750 or use one of the load balancing examples in the wiki. I don't use Rockets, but this is easy enough to do on a routed all MT network. (policy routing)

chucka

I am still having occasional problems but not nearly as often as before I started closing with the exit button. In fact, I thought it was fixed but I have had a couple of towers with lots queues on them reset. Resetting the columns now and then is not nearly as frustrating as every time you log into...

chucka

This would be a really nice feature......or fix. Whatever, it is a very annoying problem for those of us who view queues a lot.

Just a workaround would be nice. I have lots of towers that never have this problem but 30% or so do. I've never been able to figure out a pattern.

chucka

You could try one of these attenuators. They are a lot smaller than 100 feet of cable.

chucka

Sounds like a job for fiber to me. Got any light poles you can attach to instead of trenching?

chucka

Really? I have a few in the field and they do seem to be in the 28 dB area. Either that, or the 24 dB panel antennas are really 16 dB. Maybe 20 db is an exaggeration on my part. I replaced a small 24~25 dB dish with one of the 28 dB grids when they first came out. After realigning for quite some ti...

chucka

ChangeIP, I really believe your question has been answered by nramos. I see this all the time on my longer links, except the periods of better than normal signals are usually followed by signals 10-15 dB below normal or in your case a -95. In my area this mainly happens at night or early AM and only...

chucka

I have a new 44GV that has this problem. Rebooting solves the locked up port but only for a short time or sometimes several hours. I've noticed that all 4 ports light up when powered on and one of the lights goes out when you plug a cable in. This seems backwards to me. The card also started making ...

chucka

Okay, good. When I say DC grounded I mean the internal antenna construction not the mounting of the antenna atop the tower. If you ohm between the center pin of the antenna connector and the outer connector it should show a direct short if it is a true DC grounded antenna. Most omnis are not. I've s...

chucka

I've seen this problem too with version 2.9 but not until a cable company trying to do wireless moved in with some Motorola Canopy trash. I can see it in every area where they have put their RF abusive equipment up. Canopy can eat up huge chunks of spectrum and you won't see it on a scan from the AP...

chucka

Chris, Problem solved. I had lots of problems with the Pac Wireless omnis several years ago, 2005 to be exact. I lost Prism radios and other radios during almost every storm. You can either use a DC grounded antenna or put a Polyphaser lightning arrestor on your omni to keep the static discharges ou...

chucka

Are you seeing these connections in torch? If so, see my post from yesterday.

chucka

I upgraded an RB333 recently and noticed a problem with torch. Torch is now showing multiple connections with the same port numbers. On a live AP it shows 500-600 connections instead of what should be 30-40. I upgraded a test RB333 and just logging in it shows 10-15 connections between my PC the RB3...

chucka

All my equipment is set up for U.S. frequencies. Channels 1-11. I always enter the SSID in each unit as it is deployed. The CPE-90s will not connect on channel 11 and I don't remember the other channels. This has been several months ago. I think it was about 1 in every 3 channels would work. I had t...

chucka

Montana, The CPE200s and the CPE80s work fine. It was the CPE-90s that refused to connect with the newer prism cards. I have 36 CPE-90s spread out across 6 of my towers and I think one old Prism card left as a spare. I have handful of newer Prism cards that won't work. :( Tranzeo seemed to lose inte...

chucka

Montana, I bought a batch of Prism cards 6-8 months ago and noticed a problem with CPE-90 clients no longer being able to connect after changing out APs. The CPE 200s connected as usual. I'm not sure about the CPQs. I have tried not to buy many of those. I tracked it down to the newer Prism cards. I...

chucka

Same problem here when using my laptop. I have to use a desktop PC to get netinstall to work for me. No serial port, so I have to use a USB to Serial adapter with my laptop. Pulled my hair out for a while.

chucka

Rosario, I went back and tried a very low PPPoE MTU setting and the problem went away. I had initially tried an MTU of 1450 and it didn't work so I hadn't messed with that setting any more. I finally left it at 1410 and the problem is fixed or at least it is a work-around. Thank you very much for yo...

chucka

Hello Uldis, I have deployed quite a few RB133c boards in router mode doing the PPPoE login and they are working great. I just have a problem with one customer that only happens when he is logged in as an administrator, on a certain website completing web forms. That is the only reason I am trying t...

chucka

I was trying to use a 133c in bridge mode to fix an unusual problem I am having with one client when using a 133c in router mode. I could not pass a single PPPoE session through it. Bummer, I thought I was finished ordering Tranzeos!

chucka

Okay, we seem to be having a communication problem here. I read your post. I have the same setup as you (an FTP, mail server, web server, and other stuff behind a MT router). I had the same problem as you mentioned with FTP. The service port helper may not be working properly after your network chan...

chucka

This was an FTP problem to a server behind the firewall in NAT mode.

chucka

I had a problem with FTP in the past with the same symptoms. I had somehow disabled FTP under IP --> Firewall --> Service Ports. Try disable/enable there and see what happens.

chucka

I have not been able to make it work......

chucka

This is something I have used in the past and it might help. Pick a point on a hill in line between the two endpoints using software to get the GPS coords. Set up a temporary low gain grid antenna transmitter pointed toward the closest endpoint at this calculated position. Align that endpoint to the...

chucka

I believe it is when using any Atheros based cards as an AP. I have read that the R52 also exhibits the same symptoms. I have 3 new antennas now with SR-2 cards and have not had the problem yet...... but these antennas have less than 10 clients each.

chucka

Sten, The ACK timing shows to be 30us on my end when I log into one of my towers with a 2511 card on the AP. I guess that is what the Prism card AP forces the client cards to when associating. That seems kind of short considering I have one customer on this tower who is 13.85 miles from the tower. T...

chucka

Let us know how it works out with the 8602.

chucka

If all else fails try a Prism 2511. How many clients are on each card?

chucka

What kind of client ? How many clients per antenna?

chucka

Nickb,

R52 is HIGHLY reccomended by me. We no longer purchase CM9, because R52 is so much better!!

Was this dramatic improvement on a 2.4 or 5 GHz link. Are you using these on 2.4 GHz as an AP anywhere?

chucka

jfan,
The switching power supply they are referring to is powering the 532 and not onboard.

chucka

If RF is radiating down your cables something like this may help.

http://mpja.com/productview.asp?product=15566+FL

Sorry for the slow response on my part.

chucka

Is the 532 on the tower or down in the shack? If it is on the tower are you using shielded Cat5 cable? Have you tried ferrite coils on the the power or ethernet cables leaving the 532 box? Have you tried bonding all your grounds to a central point? With RF problems you just have to keep experimenting.

chucka

This card shows up as a AR5212 and works fine. Wrap boards need the latest bios for the board to come up without rebooting the wrap board. I've been a little disappointed in the output power though. The 200mw cards seem to put out about 100mw or less in my testing. 4-7 dB difference between the WLM5...

chucka

The local IP address is in the PPP/Profile not under IP/address. If you set an address on the wireless interface instead of the PPPoE profile you won't need to use PPPoE to connect. I only temporarily set an IP address on the interface to test connectivity to a CPE during troubleshooting or such. Wh...

chucka

I ran a test a couple of months ago. I added a vertically polarized test link to my towers that make up my 32km horizontally polarized link. The vertical link which was mounted lower down the towers was weaker(mid 70's) and dropped first and was down for several hours before it re-linked. The origin...

chucka

Thanks for that explanation 'dbostrom'. There is definitely a correlation between the calm air and my link signals. I have sat and watched as a link gradually goes from -64 to -88 and then 'blip', it's gone. :-) A few seconds later (usually) it will reappear at -86 or so and slowly it will go back a...

chucka

I saw the calibration note, but I have only turned it on on a short test link I have running, so far. I can only think that maybe I am picking up some interference from far away when conditions are ideal. Unless of course, it *is* temperature related. It doesn't cause much of a problem because it is...

chucka

I would at least use the 32 db dishes. I have one link at 32km. I have occasional dropouts, maybe 5 minutes of down time per month(-62 to -68 typically). This is with a 29 on one end and a 32db on the other. I plan on upgrading the 29 to a 32db dish when I can. This link was originally two 29db dish...

chucka

With version 2.9 you can specify a minimum signal level in the connect list. I have never tried this. I guess that is what it is intended for but I could be wrong. It may also only work with MT clients.

chucka

Is the glass tinted? Some types of tinting use metal particles. Drag it outside and try it.

chucka

I am seeing this also on a router used for backhaul to two towers after upgrading to 2.9.6. One of the links that is running -48 to -52 will drop with the 'extensive data loss' message. It seems to usually connect right back and I have had no complaints from customers. My main problem is it fills up...

chucka

As far as improving your -78 signal. Try a pair of th 28db solid dishes. I've tried the 26db grids and they seem more like 20db compared to the solid 28db dishes. They might be 26db if they were solid.

Chuck

chucka

He said 3 RB500s with 3 SR2 cards. I'm sure he's talking one per RB500.

chucka

I set my max limit to 10bps. If a customer asks why their music won't download I tell them "any of the *legal* music sources should work fine".

chucka

Antenna A is the U.Fl connector and antenna B is the MMCX. I did a lot of testing today with the SR5 / EM-9 / CM-9 cards. There was no difference in output between the MMCX and the U.Fl connectors in my tests. I'll try to post the results from all my testing here later when I get time. I have two SR...
