Thanks I try the arp-proxy, and not does any backup to my mikrotik.

mgutz2

Nobody have this problem?

mgutz2

Hi, I have a serious problem with mikrotik. I have several multi-point networks, all in bridge mode,on my clients I use public IP addresses, the problem is that I have assigned a network/24 per node and when I go to use the address on the customer's servers, I always warns that the IP address is al...

maybe your antennas are very closer of other antennas in the tower. you can use noise-inmunity on advance menu and put on ap y client mode for try, other sugestion is set the scan list to only one frecuency on cpe mode. this help you to a fast reconnection link. you can do an analisis spectral too, ...

mgutz2

are you use the nv2 protocol?

mgutz2

mgutz2

when this occur always i have the gain no equal, one site can have -65 and the other -75 i loss 10db.

mgutz2

i have the same problem in on rb411ah try to conect to rb711-2hn, the other ratio let me login and pass but no conect any way.

mgutz2

create the vlan 1 and link this to ethernet interface, put your vlan id, now create the vlan2 and link this to eth too, put the vlan id. and now use on the nat of hotspot the intrface vlan2 (not the ethernet) at the vlan1 put the magnament ip an the gateway the vlan2 must be have an ip too. the vlan...

mgutz2

hi, this equipment has reaches by electric storm? i smell must be go to rma.

mgutz2

Nstreme is a Mikrotik propietary funtion, yours cpes must be are Mikrotik too for use tihs protocol. Nstreme let reach more trougtput, reduce the ping times request, i always use this protocols and is the reason for i use mikrotik. on AP Nstreme=enable framer-police=best fit on cpe put only Nstreme=...

mgutz2

Efectectively for 100mts is not enouch anttena, i use this http://www.flyteccomputers.com/details. ... x%202,4GHz this have a mmxc conector for rb751, select the antenna b on mikrotik and work very good.

mgutz2

the frecuency 5350 is not stantard channel and on your scan-list of client cpe are by default, you must put the 5350 frecuency on scan-list and try.

mgutz2

are you updated the firmware?

mgutz2

this smells to a loop?

mgutz2

the rb411 only works on bridge or cpe mode no for multipoint at less than you use virtual aps, what distance are? what polarization is using? the cable loss? what mini-pci models uses? la tarjeta rb411 solo trabaja en modo cpe y no como ap-bridge, a menos que utilices los virtual-ap, que distancia e...

mgutz2

virtual ap?

mgutz2

the dbii f50npro works fine on 4.9ghz is fcc certifed on this frecuency, i no test on 4.8 or 4.4ghz.

mgutz2

if you are out of range of -53 to -68 the performance is poor, chek your levels maybe can be a difference.

mgutz2

i use the rb751-2hn and have good result, if you want to cover a very big area i recomend the wavion equipment, but remember, the internet is a two way conection and must be have present the power of the laptops an cell for comunicate whith your ap. some times use of powerfull Ap no agregate benefits.

mgutz2

can you post the configuration? are you use the last version?

mgutz2

for point to point i use bridge on one side, protocol unknow, only n, for 5ghz i recomend the f50npro mini-pci card, super channel for choice the best channel, on data rate a use advance data rate, on nstreme activated an framer-police best fit, on ht activate the four check for dual polarity, your ...

mgutz2

your config is ok, i use this and work fine but only on point to point i never test on multipoint.
on station-bridge works fine too and on many times work better than wds mode.

mgutz2

no diference on interiors location and short link. only if you want to do a point to point conection.

mgutz2

hello partner, you could tell me if you rb5shn worked well? the best configuration is one side in bridge mode and the other station-bridge, enables Nstreme and on frame policies choose "best fit", find the best channel for 4.5 km R5shn card is too strong so we have to turn down the tx-powe...

mgutz2

I have never connected without antenna and both are new, I have over 100 mikrotik devices working, and others have been burned by lightning, but had never seen a case like this. Nunca las he conectado sin antena y ambas estan nuevas, yo tengo mas de 100 equipos mikrotik trabajando, mas otros que se ...

mgutz2

whats cpe model is it? the major models of cpe on mikrotik have the watch dog activate, maybe you have activate it and the client are restarting.

mgutz2

ver 5.17, not be contacted to mikrotik.

mgutz2

I already did and end hurting my mainboard to a diode that overheated, if the card without activating the turn on it I can see,and configurate, but when you enable it all comes down. ya lo hice y termine danandole a la tarjeta madre un diodo que se sobrecalento, si la tarjeta la enciendo sin activa...

mgutz2

1) for a multipoint configuration is the AP- Bridge. for a point to point is birdge 2) bridge station is the best . 3) change it to 20MHz, remember you have to spend a lot of traffic and you need space in which to pass. 4) the superchanel you can use if you want to transmit outside of the standart c...

mgutz2

The R5HPn is a single channel and I have not been able to run, apparently consume much energy and you can burn the motherboard. I recommend you use the RB411ah or better the new RB411AH RB411GL possessing gigaethernet port, and RF card I can tell you the best I've tried is the DBII F50n-pro, I have ...

mgutz2

Buy two R5SHpn to evaluate and when I connect to a RB411Gl card, everything works fine, until you activate it through the software, the motherboard is restarted each time and not let it load the software, in addition to that is heated as a demon, this happens to me with the two new cards, I have tri...

Note that you must not use the eth port on the bridge, this is because the vlan are linked to eth port and should not add on any bridge, the port of your switch must be in trunk mode and you can only monitor done by assigning a vlan for that. for all other customers must do the same process with the...

mgutz2

I have implemented a network I so, I will make the diagram and put it here to tell me if this is how you want it

mgutz2

I have done this type of link, but I recommend you use 2.4GHz frequency becouse radio mobile maps are very old (around 2005), and radio mobile does not take into account the vegetation of the area. utilizes dual polarity.

mgutz2

you want to connect your customers to a single ap?

mgutz2

enable super channel and choice more frecuency or activate dfs mode and left to mikrotik choice for you.

mgutz2

is not recommended to use three cards in the same Radio frequency band within a single radio, RB433 cards were thinking in three different bands at once, 900MHz, 2.4GHz and 5GHz, but not three 2.4GHz or 5GHz cards or 900MHz , this will cause interference between them.

mgutz2

need to leave enough space between the spokes working in the same band, that is not self-interference between them, if you use several mini-pci in the same routerboard (such as RB433), try not to be of the same band, bone in a mini-pci 2.4Ghz and one in 5Ghz and never the same band. although attempt...

mgutz2

change the 6v 470uf filter in the main board, always these are the problem.

mgutz2

r52hn- nv2 - bridge and station bridge, xr5 is only 802.11a and the maximun trougthput is 20m half duplex

mgutz2

uhmm, I have not seen MiniPCI native that frequency, rather I think they use a frequency converter.

mgutz2

go to wireless, press wireless tab and protocol choice nv2 in both sites, first the remote an after local

mgutz2

12v would not recommend it because the voltage drop in long cables could cause you problems.
You can use 18v but stp cable that are not too long.
24V is the voltage works best for me.

mgutz2

try nv2 and 40mhz below or above, mpls is more efficent, put data rate configurated an select mcs on hight data rate. on advance select hwretrieves and change to 15.

mgutz2

can do a factory reset, connecting the contacts of this point in the picture below. I have already had these problems with these cards and the version 5.5 to 5.7. greetings.

mgutz2

i used wan killer of solarwins and ftp trafic for my test.

mgutz2

Yo he hecho pruebas en el campo y he llegado a obtener hasta 30mbps full duplex aproximadamente 65mbps en half duplex, esto es pruebas de lan a lan y utilizando doble polaridad a unos 20km aprox, si quieres obtener mas puedes utilizar nv2 y a 40mhz. Por cierto con la version 5.7 se ha mejorado el pr...

mgutz2

If you want your cpe ok bring only 802.11n then, disable in the data rate all the options that correspond to the protocols 802.11a/b/g and leaves the msc that you need. if you leave in mode cpe only, then the seek the ssid with whom strapped and is a slave of the base, so change their modulation as ...

mgutz2

yo he visto este problema, pero lo he resuelto cambiando la fuente, no se si ese sera el mismo caso que el tuyo.
I have seen this problem, but I fixed by changing the power source, will be the same case as yours.

mgutz2

The problem may be that the radios are very close and are saturated the lna rf card, I recommend separating them a bit or use some metal grille as shielding.

mgutz2

uhmmm interesing.

mgutz2

i have this problem in rb411 and rb411ah an ros version 5.5 to 5.7, downgrade to ros4.17 and try.

mgutz2

in ros 5.5 to 5.7 i have tihs problem on rb411 and 411ah, i mus be do a downgrade to ros4.17 an is more stable. in my case is to 100,10, half or duplex conection.

mgutz2

eth port flaping is persist in rb411 and rb411ah

mgutz2

the truth is that at that distance would not have problems with getting the 20mbps, but with the amount of radios you have interference on the tower must be overwhelming. something I learned in radio frequency is that not everything is written and often the spread behaves in unpredictable ways. I wo...

mgutz2

In that manual you have placed online, there is a step you did not, and is add ports that will participate in the bridge.
in the Ports tab do click to Add (+) buttom, add the wlan and eth ports at both sites ap and cpe.

mgutz2

refer to?

mgutz2

ap site, configure it as the first graphical client side configure it as the figure 2.
for the bridge on backbone it is more reliable use the mpls bridge, wds is more inefficient. check this link and sorry by my english.

mgutz2

if you can change them all, then exchange them. do not know why these cards have poor quality filters, because this problem only I've seen in these models .

mgutz2

los mensajes son los mismos, una de las direcciones macadress proviene de un cliente conectado a mi wireless, pero no corresponde al radio que se conecta, me parece que viene de un router que el cliente tiene en su red. messages are the same, one of the addresses from a mac address connected to my w...

mgutz2

must try if you turn directly connected to the jack. Sometimes this damage is lightning or if I had my tower was hit by a line of action that was nearby and equally so I burn my radios.

mgutz2

I have recently had these problems too. I have a remote client to 6 hours from my place that I had to enable watchdog because I lost the connection with my cisco switch. I tried everything to change the settings on my switch port half, full, 100, 10 and nothing, until you restart the RB411. I am cur...

mgutz2

I have the same problem, but I found that mac adresss from a customer router that connects to my wireless card, I have not yet determined which protocol is the cause of this message, I hope to share ideas.
Greetings from Nicaragua.

mgutz2

I have had problems with these motherboards, the cause of problems like yours are filters that are damaged, I have changed and the problem is resolved. Usually these filters are 680UF and 6.3V.

mgutz2

if the cards are going to use much power, also consume more power. you can use 3 cards but you can use low power and remember: the motherboard has a limit of power that can give to mini-pci ports

mgutz2

hola yo tuve un problema similar con la rb433 lo resolvi cambiando los filtros de alimentacion se los quite a una rb411ah que tenia en el deshuesadero y el equipo funciono de maravilla. si no podes hacerlo entonces enviala a rma. saludos.

mgutz2

so in bridge menu add a bridge1, add on port the interface eth1 and wlan1, here your have the bridge. Now on wireless menu put the mode on station-wds and put the ssid of your bullet, in wds menu choice dynamic and prefered bridge choice bridge1 and ejoy.
lucks.

mgutz2

use in advance menu Hw.retrieves 15, nstreme best fit try at 20mhz first, sometimes at 40mhz work bad by interference, remember the link have two point and the interference is on any of these place. put dfsmode no radar detect for best channel, you can configure the scan list at your frecuency range...

mgutz2

I recently just installed a link to 45km with which it had problems was very high gain 85dB, was using dual polarity and there was no link to that gain. My solution was to use two antennas at the same polarity and the gain rose by 10 to 15dB being between 70 and 64dB. sacrificing the bandwidth but m...

mgutz2

I already I have tried and it worked fine.
how much traffic you want to spend?

mgutz2

the xr2-2.3 work good on 2.2ghz the power is reducted to 50% about 200mW in 2.2ghz.

mgutz2

No se si habras montado las graficas reales de la antena rocket dish porque miro que el freznel esta muy abierto, yo monte un enlace punto a punto a 45 km y he logrado pasar 20mbps full duplex a 20mhz, supongo que a 40mhz se podria lograr algo mejor, pero no me aventuro hacerlo porque la zona donde ...

mgutz2

Channel selection depends on the band you're working, in the 2 GHz band, each channel has a separation of 5 MHz each and 20mhz radio uses the 802.11b / g, so the only channels that are not overlap are 1,6,11, if you fit in the middle of any insurance they're going to affect two channels at the top a...

mgutz2

I do not know if your test is LAN to LAN, 802.11g in all tests I did not give you more than 22Mbps half duplex with Protcol udp and tcp protocol will get less because this is three ways before establishing a communication, making it slower. when evaluating a wireless link must take into account that...

mgutz2

I have also one of how to do nat, if you served the last I can go the other.
Greetings from Nicaragua.

mgutz2

do not know if this is what you need, this is a tutorial I made for my classmates, I did it with a program called Wink, I hope you serve is the only thing that is in Spanish.

hi all, I mounted a wireless backbone between two sites, but I need to spend vlan trunk between the two sites and also monitor the radios connected to the backbone. how I can activate a management VLAN to the radio and let me pass the other traffic as a bridge? [url=http://img194.imagevenue.com/img....

mgutz2

I recommend you use one as short as possible

mgutz2

i vote by this ++++ Timing syncronizaition.
for not doing much hardware change I suggest a software that can generate the clock and the other that can connect to it and synchronize their clocks

mgutz2

thanks

mgutz2

hi, my question is if in mode n only with a r52hn the spectral bandwith is of 40mhz or 20mhz? and if i want to works in 20mhz where i configured this option? thans an sorry by my bad english.

mgutz2

what model of canopy are?, i see the canopy works at frecuency 5725 to 5825mhz @ 30db, you can use the low band in 5Ghz from 5.125 to 5.6Ghz for example, in the high band only can use 3 channels because the bandwith is 22mhz. some models of canopy are ofdm and others are cck modulation.

mgutz2

and you can not put two antennas with opposite polarizations? vertical and horizontal sectorial?

mgutz2

Well, I found a card XR2-2.3 seems to give me a 2.2Ghz 200mW and 600mW at 2.3Ghz. great!

anyone knows a good card to work on 2.2GHZ? I live in Nicaragua and i have licence for this frecuency, but the r52xx or any card in 2GHZ have not the same power in 2.2 Ghz and 2.4Ghz, usually in the 2.2Ghz have less power. thanks.
