I am struggling to setup Mikrotik CHR on ESXI 6.5 with Intel 82599ES 10Gb SFP+ Adapter but its showing weird issues which i have tried to resolve since a week but i am failing in all aspects. Issue : When Mikrotik CHR is used with 1G Virtual NIC , everything works perfectly. When Mikrotik CHR is use...

You can set different ip address on the same interface and use that one for second peer. Sorry for bumping on to this old thread but it resembles to what i am trying to do. I currently have a same scenario where I am trying to establish BGP with same remote-address from 2 different AS. It's giving ...

Hi, we have installed XR2 card for distribution on a PIV system with 512Mb RAM , we have about 60-70 clients connecting to this and getting between 128-256kbps connections. we are getting very high latency and regular RTOs. Amazingly signals are good ack-timeout is on dynamic and varies between 30-...

thnx ping pppoe <> AP .. Ok ping pppoe <> wds-st RTO (but it shows in arp) ping ap <>wds-st.............ok for workaround we shifted the pppoesever to station side and everything is working well but one segment is dead as they can't use the net. Change the IP of the WDS-ST and you should see the da...

I have one link running fine. Its just 1km distance.There is a pppoe server connected with the other end. The authentication was going find frm last few months. Then suddenly it started failing to authenticate. Strangely I can ping the clients and everyone from the far end but cannot ping the serve...

I think you can have Sangoma 55141 Dual Serial. User converter for V.25 to G703. I need to input G.703 So, a v.25 to G.703 is not required. I am trying to add the E1 port to Mikrotik inorder to bypass the use of a Lease Line Modem. And Ashish, i did not get Sangoma 55141 Dual Serial card at the res...

Does anyone knows the availability of E1/T1 cards or E1-Ethernet bridge having below mentioned specifications ? G.703 Interface Framing : Unframed Line decoding : CODIR Mode: TX/RX I have searched a lot but all in vain . Anyone contribution will be greatly appreciated. Sorry for being desperate Thanks

Honestly it sounds like a perfect application of 802.11-n draft stuff. 802.11n is designed, intended, and works best in a highly reflective environment - which is exactly what you've described. It's also my understanding that at the MUM coming up there should be some announcements about 802.11n ......

indianboy

My recommendation was for IndianBoy in an industrial environment, with lots of steel. In an urban lanscape there is little you can do for buildings and such. In this scenario you are best to plan the layout of the sectors to minimize reflective influences to the AP. The clients are a different prob...

indianboy

In the stated environment I would suggest that higher frequencies are better. You are dealing most with reflection. Use Lower power with higher number of APs for coverage. Use a radio with as poor a receive sensitivity as possible. The Higher frequencies will attenuate quicker than low frequencies,...

indianboy

can you give us any wireless card that can lower my frequecny and what is the best frequency that can make my None Line OF Sight to be better ... because I can build any sector with my own frequency , my latest sector that i had , it was 2.7 ghz but I am searching for a good wireless card that can ...

indianboy

by the way i finally finished my antenna that can be on 2.7 ghz so I really need the card .

2.7 Ghz card is not available as i know. But it is planned by Ubiquiti to launch such a card which will support 2.7~2.9Ghz.

Check out their website for more info ....

indianboy

Ouch. If you really want to cover an area with 5 km radius, want to connect the clients even indoors and have "industrial" environment (concrete, steel, metal, ...), then you will have a hard time. You'll probably have to install a bit more than one AP to cover that range, and even then t...

indianboy

there is no such thing like NLOS frequency, as it highly depends on what is your obstacle. will it absorb or reflect the signal. The obstracles are mainly trees ( absorbing element ) and iron/steel ( reflecting element ) The setup need to be with a radius of 5 kms NLOS in indoor with walls, concret...

indianboy

No one ???

indianboy

Anyone please let me know if there exists a true non line of sight frequency apart from 900 Mhz in 802.11 .

If yes then which is the frequency and which wireless card supports it .

Also does Mikrotik will support the same ?

indianboy

What is G mode?

802.11b - 1 ~ 11 Mbps - 2412 ~ 2484 Mhz - 5, 10, 20 Mhz

802.11g - 1 ~ 54 Mbps - 2412 ~ 2484 Mhz - 5, 10, 20 Mhz

802.11g Turbo - 1 ~ 108 Mbps - 2412 ~ 2484 Mhz - 40 Mhz

Hope it helps

Does ROS support 2.5 Mhz Channel Spacing ? I am curious to know because i have a data sheet with me which mentions that the configuration software is WinBox and advertises a channel spacing of 2.5 Mhz in 2.4 Ghz and 5 Ghz.

Anyone having experience please let me know as i am too confused..

I have the trango broadband link calculator. I plugged in all my custom mikrotik values, and it tells me at 20miles: the Fresnel radius is 69.66 ft earth curvature is 50 ft and required antenna height is 119ft. expected signal is -63 as we are using 25db grid dish ant's not having experiences with ...

You need a high sensitivity, less noisy card. Compex cards are often called as bad junks and not advised for such setups.

For mini-PCI cards best bet are :

SR2
SR5
DCMA-82

DCMA-82 topping out in the list with a peak output of 1W in b/g and 400mW in "a" mode.

The choice is yours

indianboy

Power lines should not adversly affect wireless. You may find that in some cases the power cables can act as an amplifier. In these strange cases you will find that the aim of the client antenna is best several degrees out from straight line to the tower (AP). Edit: Also consider this: Octaves of 6...

I have established such a link of 6 km for one of my customer . In the middle there is a 33Kv Power Station and high voltage wires just in the RF Path.

Thanks guys, It's interesting to see that there are different opinions and supporters on both sides. Obviously you all have good reasons to believe that a certain size of omni power is better for AP.

The 10dBi don't go much outside the building, which is good. The AP with the 15dBi, I can access from a quarter mile ...

I too use heat gun with RTV Bars. Those are good ... atleast it keeps the connectors look like new. but i am unsure how it is effective in keeping the interference out.

Gotta see the electrical characterics of my silicon bars.

indianboy

Noise level does not increase much with the higher gain omni on top of a building.

So, you do accept that noise level increases with the increase of gain.

What an irony..

First of all : 1. I seal off all my U.FL Connectors. 2. My Spectrum analyzer shows some interference in 10 Mhz near channels So i made a rule that there are only 2 non-overlapping channels. i.e i always assume that the channels are 20 Mhz and 10 Mhz interference on both side. 3. I always use Metal e...

indianboy

As i already said before thinking of anything try to scan your are for wi-fi signal. If you do not have a crowdy spectrum then noise from 15dbi Omni can be acceptable as it will definitely boost your range. If it was a Directional Antenna then the matter would have been totally different. The noise ...

indianboy

At roof level, 15dBi. It has a tighter beam than the 9dBi, it has more rx capability than the 9dBi. I've done this. I really don't know where these guys are coming from. The higher gain antenna the better. The only catch is as mentioned above, XR2 puts out too much power. You'd have to run it down ...

indianboy

tgrand, if the issue is possibly the AP hearing the Client laptop (which almost always is the issue when serving laptops) why would he want a lower DB omni? that would affect the APs RX too. areyou using a laptop to test? maybe that needs a better card..or try a different laptop. The lower the gain...

upgrading to 5Ghz is not an option as he already states that he can't afford to upgrade.
