So it turns out we have several boxes behaving this way. These are mostly RB112 serving as little leaf nodes and dishing out 900mHz access to connections numbering from 3 to 10 clients.

For what it's worth we had another "event" today. This time I'd scripted the AP box to take a look at what was going on and report in prior to rebooting. Basic deafness; wlan interface apparently stopped hearing anything, midstream. I'm going to put the same script on another box or two an...

If there are other RouterBoards that measure and can report the input voltage I'd love to know the model numbers. Bear in mind, what's useful for PV monitoring isn't the regulated voltage report such as what's available on the RB230 but instead the input voltage arriving at the barrel jack or POE. (...

While looking for some other information I just read that the RB411AH allows operators to monitor the -input- voltage to the board. This is an enormously useful feature for those of us running remote gear on PV or other off-grid systems. Does MT plan on producing the RB411AH for long? Equipping any ...

We have one RB112 box serving as an AP doing backhaul duty for two lightly populated sites (max ~1.5mbps tx) recently upgraded to 3.28 and showing somewhat similar symptoms.

Superpass makes some nice horizontal 900mHz sectors for 300-400USD, price depending on pattern width and depth. We've got a lot of them deployed and have been very happy. H/V separation is good.

MKT CPE does not pickup the request as it is not addressed to its MAC address of the antenna. As such, the router never gets the offered IP address. If you're using the typical ISC dhcp server, set "always-broadcast true" for the address class you're having trouble with, in dhcpd.conf. Th...

I understand that the horizontal ones are better, just can't figure out why they cost 2-4x as much ... is it super high grade gold inside or something? Does the mfg process take twice as much time ?

why are the horizontal sectors 2-4x the price of a vertical sector ? Are they that much harder to make ? Is it worth the price difference ? Less energy going into earth and space, more goes toward horizon. But ghmorris makes an excellent suggestion; if you can't spare US $400-$900 for an "offi...

It's not documented in the PDF I have, but if you open a terminal window to your AP, look at the "special-logon" command. Basically you create a special user on the AP that links a telnet session directly to a serial port.

"I am alive and on planet Earth. What should I do next?"

More information needed to be of help, but generally speaking an SR2 w/a Mikrotik is a pretty romantic marriage, especially compared to a union between a geriatric unsupported chipset and an amplifier of unknown provenance...

BTW, does anybody know if RADIUS mac authentication will work in conjunction w/a Prism card or is that broken as well?

please look at this note: http://www.mikrotik.com/docs/ros/2.9/interface/wireless.content#4.13.16.4 Interesting punt. I wonder what workaround other manufacturers came up with for all the Prism-based products that --do-- properly support WEP? We just spent $500 and a full day having a tree climber ...

We've been quite happy with Pacific Wireless antenna products. Their sector antennas are excellent value for the money. Our only complaint w/Pacific Wireless is their spotty and inconsistent use of stainless aiming hardware. We've got quite a few of their 5.8ghz solid dishes in use and while they're...

Will there be problem with upgrading first "the core" to 2.9.14 and after that the other routers. I mean is there problem 2.9.14 to work with 2.9.8 - wds/nstream ? Don't know about WDS, but we've had no problems (so far knock on wood pray to appropriate cloudbeings etc.) w/one end running...

mostly windless conditions

Ah, so! Some information, anecdotes about ducting here http://forum.mikrotik.com/viewtopic.php?t=5770.

Very hard problem to solve if indeed it is ducting. Surplus jet engines strategically placed along path?

dbostrom

Is this happening in windless conditions? Calm air can lead to inversions, layering and hideous ducting. Might be worth collecting the data UniKyrn suggests and then seeing if there's a correlation with weather conditions.

Adding another good report on 2.9.13 here. We have a partially complete AP and backhaul site that was running 2.9.5. The site is set up w/a 14dBi 180 2.4ghz sector and a 29dBi 5.8ghz backhaul antenna. The backhaul is not yet running, but we had very marginal contact with the new site from another of...

What happens if you increase the MTU on the EoIP tunnel? I've noticed that if I try to ping through an EoIP interface w/ a packet larger than the MTU, RouterOS complains with a message, "packet too large and cannot be fragmented". It does sound as though there are some misbehaving routers ...

Sorry to disagree, but, amps can work just fine if you use high quality units and engineer your system properly. Agreed. If you use an SR5 or SR2, you're using an amplifier. Some years ago, in another life, I did engineering for AM and FM radio stations. Typically we'd use a device called an "...

budi_a, We're using manual tx power, with the cards dialed pretty far back from the maximum output for a given rate. That was the case prior to the units volunteering to change their mode to fixed. The spontaneous change of tx power happened only once, the very first time we made the change to 5mhz ...

Whether or not Mikrotik makes source code available superficially means squat to 99.9% of users. The more important question (to me, anyway!) is whether Mikrotik offers useful patches back to the kernel tree. That's where most of us could benefit from Mikrotik when it comes to the world outside a Ro...

If it's any help, I just had an interesting experience while trying narrow band mode that sounds similar to what kujtimhajredini describes but appears to be reversible and definitely not lightning-related. Layout is an 2.4ghz MT client and AP situated about 42km apart, bridging a group of customers ...

Perhaps the first thing to address is, "What am I selling?" Bandwidth? Connections? Convenience? Annoyance? Here in the U.S. we have approximately a fifth of the workers in our "healthcare industry" busily occupied with figuring out why people should --not-- get healthcare. It co...

the check disk sometimes gives out misleading messages, `errors corrected` often simply means that something had changed. We will improve it, meanwhile don't worry about it Heh!

Do a web search for SR5 cards and look at the specs. As the speed of the link is increased above 24Mbit, the power output of the card is reduced. 24Mbit is the highest rated speed that still produces 400mw output. By the time you get to 54Mbit, the output drops to 100mw. Yeah, good idea (doi!) , an...

Can anybody definitively say what's up with the power level vs. frequency vs. rate with these cards? Elsewhere on this board I've read that the SR5 reduces power when run below the 5.8 band. Here on this thread there's a hint of that: "I would sugesst to set the freq on SR5 5800 in turbo mode. ...

As ejansson says, it can work. We have a small handful of users at these distances but it's a matter of pure luck as they happen to be up on hillsides and can see APs that also happen to be highly elevated on topography. There's also the matter of then having to set very wide ACK windows for these u...

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 i...

Rant about connectors here. U.FL connectors are touted as "the world's smallest" coaxial connectors. This is just fine for teeny-weeny applications such as the guts of a cell phone or when packed into a laptop but not so great for applications on a more normal physical scale and especially...
