Buddy,
If you have things configured on port 6-10 on ur RB 2011 how do you expect to find them on RB 750. Also RB 750 has no wireless.
Change those setting and your export import will work good.

mahnet

You can use your SXT or NSM5 to login to your hotspot with a PC or cellphone connected to i using the Dlink Router. The only factor is that you will have to autheticate it atleast once from your cell or PC or laptop, everytime you loose connectivity from your ISP.

Mikrotik should allow site to site VPN.
Try it with dongles or dsl connections.
But I guess you will be needing static+public IP at each site.

connect you Ethernet cable to any port of the 1100ahx2.
login through winbox
open FILES on the 1100ahx2
drag and drop your new router os into the filea folder
when all files are copied, reboot the router.

100mbps at 40km .. who else can match ...

bandwdith test posted. i am sure it will get better with some tweaking on either sites.

rb800 should help OR even a 433ah will. 411ah has too little ram to handle that much bandwidth. hence u see only 4-5mbps.

Hi if you want use x86 architecture you can i think if you use dual core processor (1GHz minimum) and 1GBps NIC and 2GB of ram theirs can handle your needs... if you want to use routerboard you can use RB1100AHx2. Good Luck My dual core x86 2gb ram 10/100 ethernet seems to have max.'d at 25 mbps. O...

Normis, why couldn't the new RB2011U with more memory and CPU speed? I would be willing to pay for some more money. It seems that Mikrotik is obsessed with having low prices, which is good, but at the same time it would be great to have more power. We have also more expensive and higher power produ...

15mbps for -50 is slow.

I did not test it on bandwidth test. I have posted results for a 30 km link on Groove 5Hn only and even that is better. In this case I just needed to deliver 15mbps.

mahnet

1-3 ms Tested bandwidth 15 mbps

Hi folks,
Just used the Groove METAL and WOW....it is a balastic missile.
Distance 40 km and signals less than 50/50 with just 27 dbi grids.

Amazing stuff so far. Dunno what so much power does to the rest of AP's on my tower.

mahnet

that is the difference between throughput and the actual connectivity. Like your LAN card is 10 or 100 or 1000 mbps and connects at the same to your respective switch but data transfer differs depending on cable quality, card quality and switch quality or other network conditions.

mahnet

i do not know about better signal because it is a 1 watt board and mostly tested indoors but it surely will arrange a better ccq. a stronger array.

mahnet

No update about MUM, New Delhi or the team hasn't reached back yet. How was Taj Mahal, Agra?

mahnet

High five to the new design.
But if we have 3 antennas, 8 dbi connected how does it affect each other.

mahnet

I have been using station bridge and Nv2 and wireless N. and PtMP and get superb through put at all sites. no latency problems no disconnects.radios stay up like forever unitl we do not reboot them.

mahnet

why do u want to go with rj11. why not extend ur UTP cable to the customer premises. that way u can directly connect to the ethernet of ur client. also u do not need a dslam. just hop around with switches every 100 mtrs.

mahnet

why not use station bridge. if ur AP is mikrotik too.

mahnet

rb800 is a good choice. better cpu , more ram that matters more than the card power of ur mini pci. r52hn is impressive & used with dual pols & both chains it does work gr8.

mahnet

Even I would support RP SMA connector on the the Mikrotik Box be it 951 or 751. Rubber duck antenna with SMA connector female are easily available and in varied ranges 2 -10 dbi so u can use accordingly. 2 dbi internal antennas don't really do the job. You don't normally use Mikrotik gear for a 200 ...

i have tried a 751-2hnD handling 8 mbps bandwidth in an auditorium seminar with 50+ users. All with laptops & smartphones & tablets. They worked with ease. No complains at all.

711-2hn is not an AP. You have to go with 711UA2HnD. Or GrooveA-2Hn

mahnet

hahaha...

and this guy made me search routerboard.com so many times.

mahnet

733?? Not seen this product yet.

mahnet

add another IP pool and set queues. But still it will not work on the port with HOTSPOT.
Or else, u can try mac authentication for the user. so they will not have to login. the username will be their mac address.

mahnet

as of now the best bet would be what janisk said. Try to connect thru the wireless interface i hope u havent disabled that as well.
Or be prepared to go up on the roof......

mahnet

i had a similar requirement and i later learnt that since hotspot works irrespective of what IP pool is assigned to the user or in his LAN hence the login page will always appear on that ethernet port. you can have another ethernet where u do not run hotspot and connect users thru that. or u can use...

I frankly do not understand this but I have faced this. If I have a Mikrotik AP like 433ah with r52hn mini pci or a 751-2Hn connected to outdoor antenna or 711-2Hn with L4 license and outdoor sectors, I find that my tplink 500g or 501g cpe does not work.

r those 15 dbi omni or just a 8 or 10 dbi. whts the spacing between omni's? can i have two 15 dbi omni's (one V omni & other H omni) mounted side to side with dual pol mini pci's. if so how far should i place them.
also what if i mount two V omni's side to side?

mahnet

r5shpn mini Pci with a 433ah should do the job when mounted with 35 dbi solid dish, or r52hn with 433ah and 35dbi dual pol. antenna.

Keep the height very very clear, no trees, chimneys, hills n high rise buildings.

i have tried this in an auditorium with 50 devices laptops/smartfones almost 20+ concurrent users and it worked good on my 751U-2hnd. No one complained. bandwidth utilisation was approx. 8 mbps. If u have more concurrent users u can go for rb 433ah or rb800 with r52hn and dual pol. mimo antenna.

+1 for the above. Tplink works Gr8 in SOHO. We do not require POE -in for the indoor unit but POE out is a must to power up the outdoor CPE etc. POE-in is like u have made an indoor device but u have its outdoor usage in mind.

which card (mini pci) r u using? at a distance of 2 km if ur signal is -68 it seems bad LOS/ bad alignment/ bad Fresnel/ bad antenna With even a 24dbi parabolic dish & clear LOS even with a 100mW card it should be -50 approx. We get -52 for a 13km distance and -68 for 30 km distance with 24 dbi ...

with a pair of sxt's and nv2 protocol u can see more than 100 mbps with clear LOS. i have tested it to 6 km at ease.

mahnet

Seems like some issue with antenna cables or pigtails or joints
the bullet m2 connects w/o them so better RX

mahnet

3G operators give a static IP everytime but they give it to multiple clients hence I guess they drop port forwarding for those IP's. Ask your 3G provider for a seperate static IP for your connection.
You can use Dydns like services instead.

mahnet

NV2 is out of question since the smartphones will not support it. It is mikrotik proprietory. Chattiness between clients can be dropped by having an access list and switching off default forward. As per bandwidth limit and routerboard I guess RB800 with R52Hn should easily take up more than 1000. De...

100 MTRS.

yes, a RB433ah is a good solution. to use 2 mini PCI
R52Hn is a good mini PCI but remember using dual pol. antenna to get the best throughput.
Also use mimo clients. if u make a wireless mesh with rb411ah and one mini PCI it does have performance issues.

This device is the best to work with omnitik. When should we expect to get from our distributors?

How is it best for ominitik?? compared to the usual SXT

Waiting for SEXTANT with the same output power !

rb 433 or 433ah is a 16Watt board. XR5 will take 6-7 Watt power each X 3 exceeds the limit of 433/433ah hence causing board reboots or hang. and so much noise 600 mW each, why do u want to create.

use r5shpn mini pci. it is a 800mw card. should give u ample power.

Why 3 antenna?

Is it because u have one sma connector for RX on chain 0 and one sma connector for TX on chain 0 and then one antenna combining TX & RX on chain 1.

I guess u r not using the MMCX connector at all.
