Re: x86 motherboard, support for ROS, more than 2 PCIs slots

The P43-ES3G that was suggested won't be a good match for you because you require low power consumption and even the best discrete graphics cards will pull 10-20 watts. If you don't need the latest and greatest CPU support and can live with the limits of 1333 FSB give the Foxconn G31AX-K a look. We ...

Re: Wireless Link info ....

Personally I am a big fan of the XR cards. I've yet to see anything except great performance where I have used them. -70 isn't what I would consider great signal, it is right in the margin for 54 mbit and therefore can have fallbacks with very little environmental change. I'm sure if you were to gra...

Re: concurrent wireless connection question

Theoretically, 2007 connections. Realistically, your hardware would limit that far before you reached the connection limit. A little more info into what you are trying to do would be useful as well as the hardware but if we said you were putting up an AP and you had enough bandwidth to distribute 51...

Re: Help for full duplex OSPF links

netinitaly, Try adjusting your weights, the way I understand it, you should set your costs so one link is TX unless that link is down and then the other link will run 1/2 duplex. I.E. Set the 5.5 GHz link to cost 11 on router 1 and cost 10 on router 2. Set the other link to cost 10 on router 1 and c...

Re: Wireless Link info ....

samsoft, For 1: When you say "best signal strength", do you mean by just a few db or do you mean by a very large amount? A few db can be explained by the superior propigation of signals at lower frequencies, also, depending on what card you are using for a radio, it has been shown that the Ubiquiti ...

Re: RB333 Nstreme performance

Jason, From my experience, I'd say yes, though my experience is somewhat limited. We are running a pair of RB333's in Nstreme with XR5's and they easily handle everything the radios can give them. I have never seen CPU load over 20% running 30+mbits of throughput. I cannot see any reason why you COU...

Re: Nstreme link scenario and questions

Just thought I'd give an update, we replaced all the junk we were running before with a pair of RB333's with XR2 radios on 5 ft of LMR 600 to each of the dishes. We were able to shutdown the site in the middle and shoot the entire link in one hop. Unfortunately, the speed we need isn't there due to ...

Possible upgrade to IA/MP1, 4 and 8?

Mikrotik, Hey guys, I just thought I might ask why the MP4 and 8 cannot be used with >400mw radios. I understand the problem stems from drawing the power from the PCI bus that is needed to power 4 or 8 radios of that style, as I understand it. To be honest, I might be talking out my @$$ about this o...

Re: Nstreme link scenario and questions

Thanks for the reply giganet, we talked last night about this very same thing and I think that will be a plan here in a few weeks. This weekend we are going to put the 2.4 link back up with the amps and push it up to 2484 using the superchannel license and hopefully then we will have 20 mhz from our...

Re: Nstreme link scenario and questions

Been there, tried that. We're using a pair of the Hyperlink Ch13 filters right now and they aren't helping much. The width on them is too wide so they don't attenuate anything above channel 9 very strongly. With 2472 (Ch13) as the center freq and the filters being 22 MHz we are having trouble becaus...

Re: Nstreme link scenario and questions

Well we are already running channel 13 on the link between the south end and the midpoint because if we run anything else the throughput goes to hell. This location is remote, I mean really remote so we aren't worried about being caught and we'd have to be causing intereference first but we'd like t...

Nstreme link scenario and questions

Great stuff MikroTik, keep it up. First post to the forum everyone so sorry if I'm a bit noobish here... I am currently looking to deploy a wireless backbone using MikroTik RouterOS and associated hardware but I have a few questions regarding Nstreme. I have played with the Nstreme 2 or dual mode an...
