Re: Bandwidth segregation Need Help

If you are suggesting that the 2 clients have 1Mb and also the other has 2Mb, then you only need 2 simple queues

Give each client an IP address

Then give one Max limit 1Mb and give other client Max limit 2Mb,

put those rules in your gateway router.

Re: Rb411R downgrade help

Hi Not that I am doubting you but: You cannot put an NPK package into the package directory directly... You have to firstly put it into files, then reboot. At that point it is unzipped and transferred into the package directory. I have tried that method. Maybe you are suggesting to use the raw file ...

Rb411R downgrade help

Guys I received a batch of rb411R, which had ros3.27 on them... Without a second thought I upgraded to ros4.5. (as is the rest of the network I have) Seems that the radio on the RB411R just does not play ball with Ros4.5. Those that I just installed continually connect and disconnect for no apparent...

Re: rb433ah interference between mpci cards

Hi Change IP I dont know whether its VSWR related. My experience used to be in the design of VHF and MF equipment. I have no practical experience in microwave design, however the theories remain the same whether its SW, MW UHF or Microwave. I also don't have access to 10Ghz spectrum analyser, else I...

Re: rb433ah interference between mpci cards

You offered to do some more tests right. What I suggest is to connect a length of leeky feedy to 2 RB units. Each end of Leeky feeder terminated into "PERFECT" 50 ohm loads. Couple the 2 units together, being careful not to expose either radio card to levels in excess of -50dbm Do the exact same of ...

ROS4.6 winbox closing with Virtual AP

Hi Guys Whats up with ros4.6 and winbox. I often use a virtual AP when migrating services, or having mixed security profiles. On 4.6 when the "virtual AP is added" all is fine, you can adjust the parameters fine like security profile and SSID etc on the new window that opens up Then accept the setti...

Re: Mikrotik basic setup

dude you have a 1MB connection.... now read the small print and tell us what your contract says. what is your CIR? 10% domestic use or 25% commercial. Is that download or is that upload. (I quote life in Spain) but many countries are the same. If you want to share this "adsl" you need to set up queu...

Re: HOW TO USE MIKROTIK RADIO AS CPE

Hi dude. Now I am lost on what it is that you want to achieve. But to say, that you posted earlier that you were in "station mode" yet on the other hand you have tied two interfaces together internally to a "bridge"... That wont work in mac layer. UNLESS YOU USE STATION WDS. station = routing layer ...

Re: HOW TO USE MIKROTIK RADIO AS CPE

Dunga, You are using station mode, but you have tied both interfaces to a Bridge. Someone shoot me if I am wrong, but you cant do that. Station mode has to be routed... (no internal bridge) you need gateway and routes added, and seperate IP ranges on both the wlan and eth. Or you can go the Pseudobr...

Re: RF ethernet filters in Fm towers

sorry I misread your post.. you are talking RJ45 connectors. Shielded yes, as there will be no contact to the frame of the RJ45 socket. But I have absolutely no confidence in that, so I make the drain wire nice and long, loop it under the RJ45 crimp (metal jacket). Back out of the plug with the drai...

Re: RF ethernet filters in Fm towers

I use shielded on my Tower, unshielded on my clients. However my tower also carries Ham Radio antennas Short wave and VHF... So with me it was a case of I didn't want to hear one whisper of noise from my MT RB's as for me my hobby has as much importance as the business. But of course it works both w...

Yes I see, I didn't scribe that very well did I. Anyhow, we have a lot in common. I was with NTL broadcast as project engineer on site refurbs as well as the DAB roll out. And I have done battle with the RA over a claim or excess deviation on an FM site, but the engineer didnt take off air readings ...

Re: RF ethernet filters in Fm towers

I have to disagree with NEST... Grounding one end of the ethernet is often a good idea. One end grounded = faraday shield and will not induce ground loops. However in your situation I would recommend that if only one end was to be grounded then it should be at the base of the tower tied in with ALL ...
