Hi,

what about a standard ap/client configuration for WISPs with discussed additions.
There are a lot of things to decide:
- preferred channel width 5/10/20/40 MHz
- nstream on/off
- movement strategy how to change config on all clients of an ap
(e.g. to switch a non nstream segment to a nstream segment without downtime)
- rts/cts
- fast setup of a new assembled clients
- how to update all clients

So some sort of best practice guide for WISPs.

I had never compared the frames / hw frames before. I'm noticing the TX comparision follows pretty close to what I expected 1.6 x on a good link, 2.1 x on a not so great link.

However, the RX comparison is way, way out of whack. The RX HW is 2200 x higher on one that I looked at, but always way higher, even on great links.

To determine links, do I need to only compare TX Frame numbers on each end?

Hi
I would like to ask for help guys.

I have a basestation with a RB333 configured with 3xR52 cards for three antennas running on different channels i.e 1,3 and 11. but what happens is that there's one card that registers 13 client and then it shows that some client's signal strength has gone up to -110dbm keeps fluctuating and then when I change the TX power to card rate from default it changes for some hours or even days then brings the same signal strength over and over again.

I have tried to upgrade the OS from 3.16 to 3.24 stable version but still without sucess. please assist guys what do I do with the link.

Clients Premises Equipment is NS2.

What sort of practical limits apply to the number of clients which can be simultaneously using a single radio card ?

Anyone got any typical numbers ?

is this Hijack thread day or what?

FAQ is nice. Great to see an explanation on this. Would love to see some examples of usage of each feature, for instance, Frame lifetime. --What the value actually represents.. that kind of thing could be useful for tuning links. also things like Burst Time, preamble mode, and noise floor threshold.. some of these are much less well known/documented.

I know however this is supposed to be simplified, but perhaps in the manual would be worth having examples there for each feature. Help people grasp concepts a little better.

i have similar opinions . i am too confused with NV2 configs and the HT settings HT AMPDU Priorities.

Secondly i want to see good examples of Data Rates configurations.
I thought having fixed data rates to 6 mbps in 5 Ghz band wld actually give me a more robust link but i practically was wrong. The pthroughput went bad and so did the thruput

On the other hand i see a guy who had some config where he had unchecked 6,9,18,24 mbps and had checked the others was having a throughput of 6 mbps. on a 10 km link
More Examples and clarifications please.

Re: Wireless FAQ

i have similar opinions . i am too confused with NV2 configs and the HT settings HT AMPDU Priorities.
NV2 is proprietary tdma that works with all 802.11a/b/g/n links. HT and HT AMPDU etc. is only for links with ´n´ (or mimo) availability.
If you can't find all info of need in MT wiki manual than try to google it. Most technology used in MT-ROs is standard 802.11 technology that has many explanations and white papers explainations on the internet published.
Secondly i want to see good examples of Data Rates configurations.
I thought having fixed data rates to 6 mbps in 5 Ghz band wld actually give me a more robust link but i practically was wrong. The pthroughput went bad and so did the thruput
The ´rule of thumb´ in througput versus data rates is 50% of the data rate is what a one way transmission of user data could be.
If signals are strong enough you should try higher data rates to acheive higher througputs.
Basically the ´best practise´is to find a data rate the link is still stable (doesn't drop back to a lower level under traffic load conditions) and set that rate as the maximum. Set a 2nd rate one step below and always set the lowest (6mb) to make sure basic rates always connect to have radios speak under all conditions.

NV2 is a little different in that respect that some, including me, on this forum sense it just works better with only one data rate set. Even de basic rate the same as the supported data rate.
On the other hand i see a guy who had some config where he had unchecked 6,9,18,24 mbps and had checked the others was having a throughput of 6 mbps. on a 10 km link
More Examples and clarifications please.
That makes sense: He has 12mb checked and 50% of that is ...... ? :o

i understand that HT and HT AMPDU are settings for Wireless N (Mimo) but the problem is that I am getting a max of 3-4 mbps for less than 2 km link whreas someone in the post has shown me a 90 mbps bandwidth test for similar distance. My LOS is very clear. Frq. is also unused at that locations. I have upgraded the ROS to 5.0 How do increase the bandwidth. even the radios do not connect at more than 54/6 mbps. the 6 mbps by itself keeps changing to 54 mbps and under load the ccq goes down to 6% -10%. Without load I find the CCQ to be 109/97.

Well, 90mbps on 2km is possible yes. But to see what your problems is you have to supply much more info. Do an export command in the console for the ap radio and client and copy and paste it in this forum.
Also show us the signals of the registered units.

Normis, as to the last topic - the instability of nv2 - I had a problem ticket I have been working with Uldis, and I can say that it is much more stable with 5.14. I still get disconnects on one particular link, but they last less than a second, and seem to occur mostly when there's a lot of data (night 'noise' video streams). Power is way down (5dB on an OmniTik/SXT link) yielding -60, but still dropping 4-8 times a day. Other links up for 4-7+ days. I hope to see more improvement here, as nv2 is a real game changer for these PtmP backhaul links.

Re: Wireless FAQ

Sun Jun 17, 2012 9:37 pm

Nv2 wireless link disconnects very often

When Nv2 wireless link experiences disconnections and in log section most of the messages are 'control frame timeout', then make sure that the router's RouterOS version is at least v5.14. v5.14 introduced several improvements for the Nv2 wireless protocol. Second suggestion is to lower the transmit output power of the wireless cards if the signal of the link is strong. We suggest to use tx-power-mode=card-rates for lowering the tx-power of the wireless card. If the problem continues try to use different wireless frequency that might have less interference. If that also didn't help, please contact support@mikrotik.com with a support output file from the effected AP and the Station which are made after those disconnections.
No mention of co-location interference or RF screening of AP's or Ptp links which prevents NV2 disconnects.

The above document was meant as FAQ for RouterOS software configuration issues. We currently do not have any hardware related FAQ for wireless tuning. Maybe in the future we will make also something like that, covering antenna types, amplifiers, line of sight, fresnel zone etc.

few options, in new ROS and RB - not covered by Wiki, sadly, but it quite handy/helpful.
thank you for making it !
could be nice to see some fundamental advices in Wiki too - like how more handy can become purchasing 12Db/15Db/18Db antenna for ~$30-$70 rather than struggling with Wifi-chips and setting, frequently for WAY better result. heck, even tiny 8Db antenna for $18 can make BIG difference, compared to used in some devices !!
drawback - need to do some cabling. but thats not problem any way[actually finding good place for antenna - is more tricky :]

[off-topic]
p.s.
is there ANY way to render PDF WITH examples(quite handy, btw, sometimes, as much as rest of most Wiki Pages) from Wiki ?]

We are planning to setup a point-to-point wireless link using two SEXTANT G 5HPnD. Need advise on the following points.

1. How much maximum practical distance is supported in an urban area?
2. How much bandwidth is supported in this case?
3. Is line of sight must?
4. Any other points to consider?

Hello,

So I have currently Hap lite as router. his eth4 is PPPoE server and SXT lite5 on my roof via that pppoe port, Loco M5 UBNT is reciever on 0.4km link then goes via LAN cable to another SXT lite 5 which is again transmitter and last SXT on 1.2km link is reciever which works as router and PPPoE Client, all other devices are in bridge. So i bought RB2011 UiAS 2HnD-IN and try to set it up insted of haP lite, my current router. but i have problems with that UBNT devies in middle.

I can't mac telnet from hap lite, or SXT to other SXT's after ubnt, and i can't mac telnet from pppoe client to hap lite.... So definitly ubnt is problem, anyone have any idea how to solve that issue?


Everything works but i can't install new Router RB2011 because PPPoE connection is not establish. after i tried 5 times I get mac-telnet is not working. even If i reset hap lit to factory settings i can't get PPPoE connection, ONLY if i restore from backup hapLite then PPPoE connection again works.

I know I'm not really good at explaining but I hope you understand.
