I've spent Thursday, Friday and most of this morning on the phone looking for a Draytek Vigor 130 VDSL modem. We recently upgraded our speed in rural Oregon...CenturyLink ran fiber to our neighborhood DSLAM...and no mention was made that they were going to be using VDSL. So my two year old Vigor 120...

After reading the forums I finally decided to bite the bullet and purchase a Draytec Vigor 120 DSL modem. I want the PPPOE client on the RB2011 so I can port forward from the ISP's IP address and so I don't have two traverse two NATs. No issues getting the DSL portion working - set the VCI to 32 (Ce...

So I'm assuming you'd hook up the bar code scanner to either the USB port or the serial port. Someone would need to write a driver. Someone would need to write a module that either encapsulated the data into TCP and sent it to a destination address...and again someone would have to write another pro...

MacLean

Why don't you start at the beginning an let us know what you're trying to accomplish? I get the impression you are trying to set up a point to point link between two networks? Do the networks have different subnets - IP addresses? Distance? What antennas are you planning on using? What are you using...

MacLean

Yup - that helps.

Try changing your channel width to just 20 MHz.

You've got a good signal to the AP - interesting that the TX rate is only 11 Mbps.

MacLean

Also check your power source...if you're using PoE make sure you've checked (or just replace) the cable.

I'd say most strange Mikrotik problems come down to power issues.

And like the above poster said...Netinstall...

From the looks of your IP addressing I would imagine your subnetting is going to be your biggest limitation - not RAM or processing power.

I've seen 4 series Mikrotiks handle up to 80 hotspot users with an external RADIUS server with no issues.

Actually you don't need a Routerboard to run RouterOS. You can run it on regular PC hardware. http://www.mikrotik.com/pdf/what_is_routeros.pdf Page 16 of that PDF explains the different levels of ROS you can purchase. Many of the routerboards come with certain levels of licenses. In terms of model n...

MacLean

Couple of things...first, since you upgraded the ROS you probably need to upgrade the firmware. Open a terminal window. Type in system routerboard print. If the numbers don't match then type in system routerboard upgrade and reboot (system reboot). Second - open WinBox, log into your router and open...

Did you upgrade the firmware?

From a terminal prompt -

system routerboard print

Two numbers should match.

If not -
system routerboard upgrade

And reboot (system reboot).

MacLean

This should answer most questions...it was posted under general and stickied... http://forum.mikrotik.com/viewtopic.php?f=2&t=66889 As for the old style loop I just put an alligator clip on the end of the ground wire and called it good. Always dab some silicone on it if you're worried about it s...

MacLean

So under the WDS tab do you have Dynamic and the Bridge selected?

-Mac

MacLean

Post some screen shots of the registration page - lets see what kind of signals all your devices are getting.

-Mac

MacLean

Personally I think you'd be better off using RADIUS and not using WPA2. If it's a university you probably already have e-mail accounts or some existing IT infrastructure that could easily be extended to provide a seamless experience. You might want to go further and have devices registered by MAC ad...

MacLean

Upgrade the RouterOS. Lots of NV2 issues fixed since 5.8.

-Mac

MacLean

We'll need more information to really help. A rough map and an idea of scale will help. As a rule of thumb you might be able to broadcast a wifi signal 360 degrees quite a long distance...but the issue is the clients. Smaller devices - which we're trending more and more towards - like cell phones an...

MacLean

If you're worried about having 30 meter tall towers for APs I wouldn't worry about it. Personally I think you could incorporate the APs into the existing signage - 6' to 8' high omnis between the greens and tees. Backhaul would need a little height, though - to get LOS. Pretty sure you'll find a lig...

MacLean

What country do you have it set too? Possibly the country setting is restricting channels?

-Mac

MacLean

Ok - this is a stupid question but I need a straight answer. If you take an omni antenna and mount it horizontally instead of vertically does that change the polarization? Short of all the obvious stuff about the sphere of coverage being wacked...

Good discussion topic...how far do you think we can shoot a microwave link in space with off the shelf hardware from Mikrotik?

-Mac

MacLean

Sticking with 100 meters. Honestly with a golf course you'd probably be fine with APs at tees and holes...and since most of those are back to back. Fairways will be fine with marginal coverage. I would use 90 degree sector antennas to push as much power as you can. Post a picture of the course map. ...

MacLean

We use Arc Wireless 23 dbi and Laird 19 dbi panel antennas. We have had to set up as many as four however to cover different directions. So...you can do your connection with as little as three antennas assuming your clients are more or less in the same direction. You'll need a fourth if they are not...

MacLean

I've got a Droid 3...am about 50m away from 16 dbi 120 degree sector antenna running off a R52-300 card in a 433AH. I'm in a tent - nothing but other tents in the way. Getting two to three bars but only if I hold the phone up. If I put the phone down it looses connection and I have to log back into ...

MacLean

What about a 750UP powering three SXTs instead of the omni? The SXT to SXT links at that distance should be right around 54 mb. Three of them will not saturate a fast ethernet link from the roof to the equipment in your building.

-Mac

MacLean

Normis mentioned in an earlier post the maximum range is around 100m.

-Mac

MacLean

Absolutely. Especially if there are no buildings, no interference (say other wifi radios or devices), and a certain amount of users appropriate to the hardware you are selecting. If you scroll down a bit I started a discussion on the 435Gs that might help answer some of the questions I think you're ...

MacLean

If the area is pretty saturated with 2.4 GHz I would suggest using horizontal polarization on your antennas and see what your signal strength is before adding APs.

-Mac

MacLean

I usually see problems with the response time of any part of the interface when the RB is experiencing power issues. Are you using PoE? How long of a cable - have you checked or replaced the cable - is it shielded? Have you tried a different PoE injector or the DC power adapter? We have a ton of 433...

MacLean

I completely agree with you about wiring each building individually. We run into a couple of big stumbling blocks with that approach...namely we don't have a tech on site and since electrical outlets are in such high demand a lot of time our equipment gets accidentally unplugged, the PoE injectors g...

MacLean

Totally agree. Lots of radios. Sectors. Check. So again - faced with using a single 435G and five radio cards all causing potentially disastrous crosstalk and interference because of their close proximity on the RB but allowing me to power the device with a single ethernet run and PoE injector or us...

MacLean

Lots and lots and lots of clients. Barracks chock full of people. Why I am leaning towards the sectors. I could imagine as many as 100 clients (or more) connecting to each tower...and breaking that up into smaller chunks would be ideal.

-Mac

MacLean

So back to the original question then - since it seems that four radios/sectors and one radio/panel for the backhaul is the way to go.

Use a 435G and five radio cards or use five Grooves/Metals and a 750UP with a 48v PoE injector stepped down to 24v?

-Mac

MacLean

Thanks for the info on the 750UP being capable of being powered by PoE - and the 48v stepped down to 24v idea is good. I do need to do some research on the amperage of the Grooves and Metals and make sure I can power 4 or 5 of them with only 1.1 A - plus the 750UP. Forgive my ignorance on dbi and an...

MacLean

From my understanding 5 MHz and 10 MHz channels will not work for "visible" access points - you are correct in that they "disappear." I think you can manually set the settings on your clients and it will work - but I an not familiar with your bridges.

-Mac

MacLean

I agree about the other DHCP server on the network. The other issue is you might have accidentally added your WAN port to your bridge.

-Mac

MacLean

Mikrotik already has a product that suits your POE needs. Check out RB750UP. http://routerboard.com/RB750UP Fair enough...but again it runs off a power adapter and not PoE itself, right? We can't run 120 or 240v lines up our towers - most of them are temporary. Which would mean we would need to run...

MacLean

Go to Wireless on the Omnitik and click on registration and send us a screen shot. Your Tx/Rx signal should be in the -50s for best results.

-Mac

MacLean

We use these all the time with 433AHs and R52s.

MacLean

Yes. I used NetInstall 5.17 and on a whim tried NetInstall 5.14. Tried both using every version of firmware back to 5.12.

-Mac

MacLean

Well...no answers or opinions from the peanut gallery. From most of my browsing of the forums it seems that installing a lot of R52 cards in close proximity - all on the 2.4 GHz band - would not be good. We're currently using 433s with a 2.4 on wlan1, 5 on wlan2 (backhaul) and 2.4 again on wlan3...b...

MacLean

I tried everything from 5.12 up and same thing every time. Most of the forum posts about any routerboard exhibiting this behavior say they RMA'd the unit. I'm way out in the middle of nowhere and a long way away from more parts.

MacLean

So SXT...RouterOS upgrade...bumped the ethernet cable and lost power in the middle. No problem...opened up Netinstall...computer configured with fixed IP and Netboot set to the next address...SXT shows up...click on the SXT...click on 5.23 npk file...click install... And ten seconds later it says Re...

Almost sounds like some of the NV2 stability issues folks have been posting about.

MacLean

You'll most certainly need to send us your configuration if you want help troubleshooting. Sounds like you replaced the board. Did you reprogram the new one? It almost sounds like you have an issue with the bridge. I would make sure you've got one and it incorporates the wlan and appropriate eth por...

MacLean

You really want your default address bound to your bridge. That and make sure to set an admin MAC address.

We've got a bunch of APs deployed that use 433s and a panel antenna for the backhaul and two 120 degree 12 db sector antennas. Problem is we need 360 degrees of coverage, and a lot of the surrounding buildings have metals roofs. I'm thinking of upgrading a couple of them to 435s and using the same p...

MacLean

Something akin to the Patriot Gauntlet and Seagate wireless HD enclosures. Also would like a variant that has both sata and mSATA and raid capabilities.
