encrypt the datastream with IPSEC VPN , no need for wpa2 or anything ...

hebeda

you need AR9390 or AR9590 cards for costum channel bandwidth support beside 20/40mhz ... AR9380 and AR9580 do support only 20/40mhz channels ....

beside that you need a routersoftware which supports that too

no mimo was used, only a single radio on a 11n card , the other 2 radios where turned off .... but the sad thing is , the current AR9160 chipset reference design (2nd revision already) may be obsolote very soon , its seems atheros has invented another hardware bug into the current AR9160 chipset ref...

hebeda

well , my point is: 11n is very useable for distance ... me and my partners have successfully setup links with 802.11n cards , just using single radio, turning off the 2x extra radios of the Ar5008 chipset in this case (there are also 2x2 RX/TX version available soon) ... with xscale based board and...

the dcma-82 need up to 6 watt upon initilialization and under full load. ive seen various older mikrotik routerboard modells gone up in smoke when using these cards ... i think 12V power supply is quite weak, i have been using this cards with RB532 and 18V 1.33A power supply successfully - but to be...

@kthameen my assumption from working with/and selling mikrotik gear for several years now is, that all the userunfriendly interface is 50% buisnessmodell ( spend more cash on education and consulting) and 50% lack of knowledge about design of user interfaces ... the lack of interface design is a pro...

how about the new ABG-N AR9260 chipset (single chip 2x RX/TX) ? i just had samples on the desk ... working good, less power consumption, minipci type IIIB again , just no mikrotik support yet ...

hebeda

the AR5416 802.11n chipset is outdated and doesnt support Radar detect in 5 ghz band which is required for europe. this is a hardware issue, which has lead to the big delays with the release and availability of the XSPAN chipsets during spring/summer last year. in last quarter last year was the AR90...

hebeda

make sure that your card is capable to support Super G mode .... AR2413 doesnt support 108 mbps , the AR2414 BB MAC card does support 108 mbps ... since the mikrotik software shows always AR2413 also for AR2414 cards dont get confused and check your card and manufacturer datasheet for more informati...

hebeda

its very good , but have a 50 ohm resistor ready for the 2nd antenna connector - these cards blow very fast away ...

i prefer personally only cards without diversity switch ... , less hassle with the blown cards ...

hebeda

for max throughout you will need a fast cpu anyways. remeber: an atheros ar5008 and 2nd generation AR90xx 802.11n chipsets will be delivered with Two and with Tree Radios inside. for full throughpout with a AR5008-3NX chipset card with 3x radios you need some cpu power - at the moment seems the limi...

hebeda

CE approval .... funny ... is this a complete system incl. antenna and case ?

hebeda

click sound on minipci cards ... means usually the card cannot draw enough power from the host computer ...

ive observed this with various brands ....

hebeda

this is how the 802.11bg-N modell from GEMTEK looks like, size minipci TYPE IIIA

hebeda

lso: are ANY of the 802.11n cards capable of operating in 5GHz spectrum? All the ones I've seen are 2.4 only, which limits outdoor applications quite a bit. a bit offtopic , but 802.11abg-n cards available very soon.... i get in a few weeks a shipment . we had already different samples here of 802....

hebeda

depends on the driver i guess ...

hebeda

i think mikrotik beta 3.xx version has included 802.11n support ...

ive never tested it so far ... maybe soon, when i find some time for testing.

i have some shiny 802.11bg-N and 802.11abg-N engineering minipci samples from gemtek here Atheros AR5008-3NX and Ralink RT2860 chipset ...

its a about timing of the timeslot signals , certain companies have adjusted this signalling to their own needs. to explain it simple all Accesspoints in the area usually see the traffic of other AP and they handle out time slots between each other to send and receive datapackets .... certain vendor...

@Bomber67 1ghz can be anything ... ixp,ppc,mips,x86 .... and their raw computing power is VERY different , especially if it comes to routing etc ... beside the cpu is the ethernet chipset beeing used also important .... just think about the crappy and buggy VIA chipset which slows down the RB532 a l...

wimax will start to be VERY interesting with new 5.8ghz WAVESAT cards, massproduction will start middle of this year i got told by a manufacturer first hand. but problem with the software support remains. i have learned that the WAVESAT linux software development kit doesnt include any basestation o...

hebeda

i wonder how these compare to the new wistron dcma-82 , also price-wise

are the new ubiqutiy cards already in massproduction ?

hebeda

go for sr2 or z-com xg-622H , both have much better sensitivity ... both use AR5004G chipset ...

hebeda

i would suggest to install the latest ralink driver on the client side to increase Tx power and sensitivity ... most rt2500 ralink cards come with quite old driver, the latest generic ralink driver will increase tx and rx ... please find them here: http://www.ralinktech.com/supp-1.htm there are also...

rb153 is not crashing anymore with certain cards for us after 2.5 upgrade ...

hebeda

it seems the routerboard 2.5 firmware upgrade did it .... gigabyte gn-wi01ht cards now just work fine 24h under heavy load , no crash so far .....

hebeda

could anyone advise please which multible cards are working with the RB153 without problems ?

cm9, RB52 should work from what i do understand.
any other cards ?
anyone tried sparklan WMIA-123AG (manufacturer GEMTEK, same chipset as CM9) ?

hebeda

we do have the same problem with gigabyte GN-wi01HT cards ...

1 card works fine with RB153 , but 2 or more and the board crash within 10 minutes ...

the GN-wi01HT uses also AR5006XS chipset like CM10 ...

is it maybe a driver/hardware issue ?

any solutions soon ?

hebeda

have you used the ON/off switch on your laptop ? which laptop modell are you using ?
.... my guess is, that your problem is not driver related, but the card/radio is turned off ...

you can find windows driver for cm9 also on my website http://www.minipci.biz/support.html

hebeda

there are some differences to the SR9 cards.

2dbm less tx power, and AR5414 chipset.

also the freqency range is a little different

SR9 is 900-928mhz
GZ-901 is 868-928mhz

my company is looking forward to get some samples from zcom soon, i will keep you updated ...

hebeda

i get next week a small batch of engineering samples of 802.11N minipci cards with ATHEROS XSPAN chipset .... regarding to the manufactuer they support up to 150mbps throughput - well lets find out ... btw check the size of the card .... :lol: manufacturer gemtek picture of the card: http://umeboshi...

hebeda

well the question remains , is mikrotik reading and showing the real tx power settings or not ?!

hebeda

well the informations regarding the zcom xg-622h are very conflicting. zcom china tells you on their website 100mw, zcom uk tells you in their productflyer for their costumers 500mw,on their website its 316mw and i got told by a zcomax sales person (zcom uk subsidary) that 28.2 dbi (630mw!) at 1mbps...

hebeda

hello i have a question regarding the tx power readings are they really accurate ? i have a highpower z com card here for testing and i get this reading of 29dbm by mikrotik os. no country set , no regulatory domain, channel 6 the card is actually scanning for a network. screenshot: http://umeboshi....

hebeda

if you use the card with routerboard , do you have a proper powersupply ? under heavy load is this card is sucking up to 1500mA

hebeda

yes works perfect, we sold many of the gigabyte GN-wi01HT 802.11abg cards for mikrotik use ...
