Hi all, i have clients connected from 1 to 12km (.6mi to 7mi) JB 12km is little far for OmniTik. I had a 20dbi Sector from Ubnt, but the equipment that was doing the job died with a lightning storm. Someone stole our ground cable... :? The omnitik survived and i connected all the clients on it and ...

CyB3RMX

Many of your signal levels are far too low. This results in low air rates for the affected clients, which will lower your total throughput for all clients in return. Aim for -65dB RX-level (CPE and Omni). Use mikrotik linkcalc to estimate needed TX-Power and Antenna-type. Try to never go below -70d...

wds with NV2 ???????????????????????? As far as I am aware NV2 is incompatible with WDS , maybe I am out of touch. 80211 mode In advanced tab on CLIENTS ONLY HW retries 10 try rts/cts = self Hw.

Yeah, thanks for making this informative and helpful for others!

I will start a tread in Mayan , latin or Swahili just to make a point...

This is an English forum, it's not my first language either but it's the one that all can understand.

Hi all, Well i have a cell in a rural area with clean channels so i put an omnitik and i have clients connected from 1 to 12km (.6mi to 7mi) The clients are all Mikrotik of course (otherway we cant enable nv2) they are mostly Sextant 5HnD but i have a few 411AH with XR5 with a 23dBi panels (the fare...

I have a solution, in production already.

Why the mistery?

why you no post the solution? we may be interested too.

regards.

Try this: Make a survey to check what its the cleanest channel and use it, remember that in 2.4GHz only 1, 6 and 11 wont interfere with each other so you need to select the most clear and see that the nearby channels are clear too. Change the chanel Make sure that you Point the antenas like this -> ...

It could be attack, read this: http://homepages.tu-darmstadt.de/~p_larbig/wlan/#mdk3

this is what i was looking for... thanks.. im pretty sure that was it..

The problem stoped, i migrated all to a 802.11n based system + NV2 on 5Ghz. so its more secured than the last one.

CyB3RMX

Update.
I have 10.2.102.0/24 as the pppoe pool, i just added the 10.2.102.253 to the AP and 10.2.102.2 to my laptop (whitch its connected with a sextant on station bridge) and the masquerade seems to work, so the problem its with the pppoe and masquerade.

Hi there, I just setup a RB711GA-5HnD to be an Access point with rOS 5.24, on the Ether side it have a public ip address and on the wlan side i have a pppoe server using radius auth, i also have wds enabled, because i have 2 mini cells conected to this AP and i need them bridged on the ether1 networ...

more people use windows than linux, it's a fact. we have very few requests like this, less than one per month. use Wine, it works perfect. i agree with you, most people use windows, but if RouterOS is linux based, and it support the dude server, how diffucult its to release a Dude server for linux?...

CyB3RMX

maybe something industrial/military ? or commercial stuff improperly installed ? If you had spectrum analyzer, GNURadio, WinRadio with this band module and etc - you can actually get some details. but generally only feds had hardware and experience to locate this both in time, frequency and locatio...

at a regular time and daily? I have never known the sun to be that specific with it schedules. Anyways, it may be something else, but i doubt it is the sun. One question though, I'd like to know if those sextants work better then the UBNTs, i'm trying to get my boss to use the Mtik equipment over t...

CyB3RMX

Sounds perhaps like a CAM Table attack ? I don't know if it's possible on the Mikrotik but on the Cisco switches I've used we used to enable Port Security to limit the amount of macs that can associate to a single port.

on wireless?

CyB3RMX

Whats the difference between stp and rstp, i know one is faster that the other, but this impact on cpu? or performance witch is better?

regards

CyB3RMX

Did ou locate in witch sector is the problem?,
Do you see unusual bandwidth load?
Look at your arp Table, to see if there any duplicated Mac.

CyB3RMX

Are you using any simple queue?

CyB3RMX

Hello, Well, first of i will put on the ether, the dhcp clientor a static ip to get the router to the internet, make s Ping to a external site so you are sure the router its online. Once its online you should put an ip address on the wlan interface. Example: 172.16.1.254/24 Then go to ip-hotspot and...

CyB3RMX

Yes, there are tools to know the ssid, if you want to connect only 1 or more stations, i suggest unchecking the "Default authenticate" and put manually your stations Mac address on the access list. This will only let auth and connect the macs you listed. Even this way is possible to get it...

output power != link quality

Amen to that, im not sure why you guys release a RB-SXT-5HPnD (1.25W - 31dBm power output).

this didnt compromise quality?.

This was one of my first equips, its running 802.11b 200mW PRISM cards, but for the amount of clients on that area i didnt put it much attention, but now that area is growing so in the same pop there is a 5Ghz sector with NV2 + nStreme Encrypted and with the Ssid hidden. So im migrating all my clien...

i just cant believe no one can answer anything, i found this weird... anyway thanks again..

Today i got another 80's Xerox connecting to my AP ?!

CyB3RMX

fancy... hehe

CyB3RMX

Im pretty sure now this is an attack, yesterday i found this MACS on my reg table and please, this mac 00:00:00 belongs to 80's Xerox devices..

CyB3RMX

btw, i wrote to support and they told me they have plans to add it, im not the first guy who asked for it hehe..

You can use The Dude to make a network map. From there you can connect to each Mikrotik device using the context menu. I use Dude server as a live network monitor, but i dont see it practical, because i dont monitor my clients but i do have it on my winbox list, so if i had folders on the winbox wi...

indoor will be best i think. i have a lot of issues, with 5.X and hotspots with a lot of users, and no control on devices loging in. Try use 4.17. Set data rates to a low rate, and use access list, to deny bad signal. Also better to use only g, not b/g. Both AP's are running 4.17, and thanks i had ...

Hi, i have 2 rb411ah with r52 radios in a Pool area in an hotel, By default the ack timeout was dynamic, and the connections really sucked,The communication between the ap and the clients was to slow, ( most of them ipads and other handheld dvices,), so i change it to indoors and that improved a lot...

Hi all, I have more than 600 Mikrotik devices, so you must imagine my winbox list how big it is and how difficult is to find someone in some cases. My suggestion is to put folders in the WinBox list so we can save our devices by name in their folder, and made it like a folder tree. Hotel Client (<--...

CyB3RMX

Sounds like everyone driving by that has a cell phone or a laptop hits it.

im not pretty sure about that because all the clients are registered and stands like if theres a crowd near the AP. anyway.. im migrating this cell to 5GHz with NV2 so this problem soon will be solved..

thanks

CyB3RMX

what you need is to use station pseudobridge, then add a bridge between ether1 and wlan1 and you are done.. ;) 802.11 doesnt allow to bridge on the station side.. :) this is like a bridge but, no matter what you connect on your ether1 side the AP will see only 1 mac address, the wlan1 one. Regards!

CyB3RMX

You could use the access list to drop anyone with weak signal, but that would likely be a ton of work compared to just enabling encryption. Best bet is to encrypt it. There is a reason that would be the first bit of advice. An easy way to reconfigure the encryption remotely is set up a virtual AP a...

As far as i know, The TX/RX rate, CCQ and the Signal level depends of the traffic its passing by through the link, it has to be some traffic to give you a more certain data.

Im asking because when the v4.2 (I think) was released I upgrade one and It won't boot again I couldn't make it come to life again, not even with net install

Thanks

Hi there
Does anyone know if the rb532x works fine with rOS v4.17 Or other v4.x?? Does it gets slow? Or what problem I can found on my way to upgrade?

Thanks in advance!
