RB751

Ackster · Wed May 18, 2011 12:37 am

Saw a post on this product early in the year that mentioned April 2011. Is there any updates to its release date?

Thanks

che · Fri Jun 03, 2011 3:28 pm

I'm also curious about official release of this product.

Fri Jun 03, 2011 3:30 pm

almost ready, I already have one in my apartment

You teaser..

dasiu · Tue Jun 21, 2011 5:41 pm

Few weeks passed, so let me join to the group of people asking the question

:
Is there anything new known about the RB-751 devices? When will they be ready? What would be the cost (approximately)? Are they still "almost ready", or has anything changed?

Ackster · Wed Jun 29, 2011 9:53 pm

Any updates on this? We want to roll out a managed router package with our customers and this would be a great router to base it on. BTW - will it handle metearouter?

Ackster · Tue Jul 05, 2011 4:03 pm

Looks like it missed the July newsletter. I'm starting to have my doubts on this product, which is a shame.

Wed Jul 06, 2011 8:55 am

this summer, I promise

Ackster · Wed Jul 06, 2011 4:01 pm

I hope so, Are anymore specs available yet? Memory & metarouter support are what I'm looking for. I have BIG plans for this product if I can get it programmed the way I want.

janisk · Thu Jul 07, 2011 10:40 am

it is mipsbe, and all mipsbe have MetaROUTER capability so far.

andreacoppini · Mon Jul 25, 2011 3:45 pm

.. still waiting for this, any news?

Raf · Tue Jul 26, 2011 10:25 am

Maybe they're waiting for CE certification?

jcrites2008 · Sat Jul 30, 2011 12:22 am

It's on roc-noc.com now. Not in stock yet, but it has a price of $89.99 for the non-gigabit one. Yikes! That seems a little high to me, but it is a higher power router I guess. I was hoping the gigabit one would be around that price though.

Edit: It says on the product page that the pricing is just a guess, so I guess we'll just wait and see!

dorijan · Sun Aug 14, 2011 8:36 pm

any news? I am also interested for this product...

jandafields · Wed Aug 17, 2011 6:15 pm

Should we assume that this is going to miss the August release date?

Thu Aug 18, 2011 7:56 am

still trying to make it for august

dasiu · Wed Aug 31, 2011 9:20 pm

OK, August ends today... And I think that many of us are dissapointed, that the 751 is not there... Could you give us any news? Any new (maybe - reliable) deadline?

laurinkus · Wed Aug 31, 2011 9:23 pm

Actually the RB751G will come after the RB751U, which will ship to distributors in around 10-14 days.

lvpoker · Sun Sep 04, 2011 6:10 pm

How about the 750UP? This was promised in August and now September. Will it really ship in September?

janisk · Tue Sep 06, 2011 1:56 pm

no, not in September - we expect them at the end of October

RB751U seems to be on time.

zervan · Tue Sep 06, 2011 11:00 pm

Actually the RB751G will come after the RB751U, which will ship to distributors in around 10-14 days.

It passed 12 days and there is not only no new router in distributor's store, but also no mention about RB751U at routerboard.com

Wed Sep 07, 2011 8:35 am

It passed 12 days and there is not only no new router in distributor's store, but also no mention about RB751U at routerboard.com

12 days since when?

12 days after YOUR information, that "RB751U will ship to distributors in around 10-14 days"

Wed Sep 07, 2011 1:18 pm

So, 2 days left? Actually, I'm optimistic about next week. But we will see.

Wed Sep 07, 2011 1:19 pm

Well considering that distributors can't even order them yet, I can't see how we can pay for them and have them shipped .....

Wed Sep 07, 2011 1:22 pm

I was always talking about an announcement. Not when the end user will hold the unit in their hands. Sorry, hard to predict that date exactly. Depends on shipping times etc.

tnakir · Wed Sep 07, 2011 3:32 pm

I thought you announced it on MUM in Budapest, Hungary

Wed Sep 07, 2011 3:33 pm

I thought you announced it on MUM in Budapest, Hungary

announcement of availability. that's different from announcement of "plans to make it"

tnakir · Thu Sep 08, 2011 10:18 am

When you announced "plans for making it", in the PDF doc, availability stated: next month.

Maybe you should skip availability predictions until you're sure.

I'm sure that's not true. When we announced RB751, we said "june" and that was in March. But it doesn't matter, you are right. We missed our promised date. I'm sorry about that, and I hope that you will be able to order this product this month

tnakir · Thu Sep 08, 2011 10:45 am

Yeah, me too.

We were talkin to our clients about 751, and it seams it will be a very popular product.

Both us and them are waiting for 751 to hit the market, and it's a bit annoying explaining to them that the product publishing is postponed over and over again

((

jandafields · Wed Sep 14, 2011 7:45 pm

Ok, it's a week later now.... any news?????

Also, since you have had one in your apartment since June... can you tell us how it has been performing? Any problems yet?

laurinkus · Mon Sep 19, 2011 12:29 pm

So where is RB751U-2HnD ?

janisk · Mon Sep 19, 2011 12:37 pm

it is operating within expected parameters

i have one too.

laurinkus · Mon Sep 19, 2011 12:53 pm

When can I expect to have one too ?

blacky · Tue Sep 20, 2011 10:27 am

Now it's listed in Germany

http://shop.meconet.de/artikeldet.php?p ... eplmkh5a96

Price: 44 EUR without tax. So now i'm waiting for it to be in stock

zervan · Tue Sep 20, 2011 10:50 am

Interesting that there is still no information on http://www.routerboard.com about it.

jandafields · Tue Sep 20, 2011 3:00 pm

Looks like roc-noc will be selling them for $59.00 when they get them. That's a great price for wireless.

tjc · Tue Sep 20, 2011 5:47 pm

Just a curiosity question, can the USB port be used as a console port? That would be very cool.

jandafields · Tue Sep 20, 2011 5:53 pm

You mean with something like a USB->Serial adapter? I'm pretty sure that is not currently possible. Drivers for all of the popular USB-Serial chipsets would have to be compiled into the kernel for that to work.

janisk · Wed Sep 21, 2011 9:06 am

no, it is not the case. USB port can be used for anything else as it is fully powered and functioning port.

zervan · Wed Sep 21, 2011 9:17 am

Which external antenna will fit to RB751? I'd like to use something like this one: http://routerboard.com/ACSWI - but it should be without cable and with MMCX connector?

Wed Sep 21, 2011 9:22 am

Which external antenna will fit to RB751? I'd like to use something like this one: http://routerboard.com/ACSWI - but it should be without cable and with MMCX connector?

the most important part is that your antenna needs a straight MMCX connector, angled connector won't fit!

when talking about antenna shape - anything will do, something like this (standing, or suction cup) is more practical:
http://www.alibaba.com/product-gs/37948 ... tenna.html

zervan · Wed Sep 21, 2011 11:15 am

angled connector won't fit!

Thanks for this warning!

I'm still waiting for RB751, but I can look for something like this antenna now (or check if Alibaba sends here to Slovakia). It seems that external antenna with cable is needed? Nothing to plug or screw directly?

Wed Sep 21, 2011 11:25 am

nothing to plug in directly, no.

alibaba is not a shop, they will not send you anything. it's a catalog of manufacturers.

zervan · Wed Sep 21, 2011 3:09 pm

Well, I will find something here then.

Let me ask one more question: RB751 has two antennas integrated using two chains, right? (something like SXT) What will be happen when I connect external antenna? Both of internal will be turned off? Or one of internal will work on chain0 and external one on chain1?

no, this will replace one of the internal antennas. you will still have two chains, one internal, one external.

zervan · Wed Sep 21, 2011 3:31 pm

no, this will replace one of the internal antennas. you will still have two chains, one internal, one external.

Well, but what about Tx power? Internal antennas have 2 dBi, so I may use 25 dBm of Tx power to get maximum power allowed here. Let's say I will connect some external 13 dBi antenna - I would have to lower Tx power to 14 dBm, so internal antenna will be practically "invisible". Or is it possible to set Tx power for each chain separately?

this summer, I promise

You missed Summer by a couple of days but it is finally here. Nice work!

DBob · Tue Sep 27, 2011 6:57 pm

Can anybody post a picture of the back side of the RB751U, along with the exact distance between the holes?

I'm interested in the mount options.

roc-noc.com · Wed Sep 28, 2011 9:17 pm

I'm interested in the mount options.

The mount holes are 70mm (2.75 in.) apart with 6mm (1/4in.) diameter head size.

It is not a great picture and 1.5MB but you asked for it.

Great!
I can mount the way I want! Thank you for the measurement and the picture.
Now, I had to buy one

Thu Sep 29, 2011 9:56 am

Hey Tom,

Any pictures of the front side of the board ?

I'm waiting for CE certification too.

Now I'm looking for an omnidirectional antenna cca 8-15 dBi - something like normis has mentioned (http://www.alibaba.com/product-gs/37948 ... tenna.html), but with straight MMCX connector. I can't find any. Has somebody found some?

you can also use an adapter to extend the connector, or to convert it to SMA:

hotspotsolutions · Mon Oct 03, 2011 9:52 am

Having just received the RB751 today (200 pieces

) I am very very disappointed to see that the MMCX connector is useless with Right Anged MMCX connectors, which I would say most if not all people use.

I haven't ever seen a straight MMCX connector before (I have after googling it) however if the connector was just slightly further exposed this wouldn't be an issue.

In my opinion this is a serious design flaw.

We will now have to source new MMCX cables SOLELY to use with RB/751 (and for our customers)

So anyone wanting to use an external antenna, start sourcing your new cables.

hotspotsolutions · Mon Oct 03, 2011 10:32 am

Good to hear normis.

Small Hack for anyone who can wait for fixed board, not the prettiest but for our own use its fine, and no need to order new cables if the design will be changed.

Removing the sticker shows an array of breakouts, I assume for future versions

Mon Oct 03, 2011 11:10 am

when I said "we always keep improving our products" you thought it was just marketing-talk ?

haha, we have seen the constant improvements with RB435G, RB750GL, RB1200, SXT, OmniTik and Groove in the last year, so Mikrotik are proving it is not just about "Marketing-Talk"

The move to Solid Capacitors is a great decision, and I am sure will please many users.

I for one am looking forward to future RouterBoard product announcements.

I've heard there are some problems with CE certification. Is it truth?

marsark · Thu Oct 13, 2011 1:28 am

Why there is a MMCX connector in RB751 instead of RSMA? (size, price, ...) ? I think that RSMA is more usual. IMHO, nice product. Looking forward for RB751G.

ayufan · Thu Oct 13, 2011 1:56 am

to make life harder :)

hotspotsolutions · Thu Oct 13, 2011 2:55 pm

RPSMA is an inferior connector to MMCX, MMCX is a MUCH better connector.

I would suggest for every 751 in the field in an office, every 3rd or 4th would pop connector in a month of two in an office where the router is in an area where people move/use the area. MMCX is will never disconnect, and with lower loss.

It is possible. At least some of the more popular USB->Serial chipsets are supported by RouterOS. I just tool a PL2303-based cable, plugged it into my 751U, and saw it show up as a port under '/ports' and it let me configure a console on it under '/system console'.

This, of course, only gives you an OS console, and not a boot loader console.
