We also have PTP connections with -20dB. You can test + 5dB on your desk and it works fine. The wifi ch...

PPPoE Server - Client optimum settings

PPPoE server setting Max MTU=1480 and Max MRU=1480 what is the optimum setting for MRRU which is currently set at 1600?
Also for clients by default MRRU is disabled, should the client MRRU setting remain disabled or be set to match the server settings.

Re: mtu in a mpls/vpls ospf vlan and routed mixed MikroTik network?

With regard to 433AH that has the lowest max L2MTU of 1526 on ether1 on the network, is the setting of 1526 for MPLS interfaces for this and all other routers running MPLS on the network + VPLS also set to 1526, correct? Another question is on this routed network using VLAN's should the L2MTU for th...

Says RB411 series ether1:1526 but so far I have only seen 411's boards with a max L2MTU of 1520?

Re: mtu in a mpls/vpls ospf vlan and routed mixed MikroTik network?

In an ideal world, L2 MTU should match on either side of a link. However, this isn't always practical as different models of routers define "Jumbo" as different frame sizes. For example, most Cisco routers top out at 9216 Bytes, while a CCR1072 has a max L2 MTU of 10226. L2 MTU serves as the base t...

Re: mtu in a mpls/vpls ospf vlan and routed mixed MikroTik network?

If you're running tagged VPLS, I wouldn't have an L2 MTU lower than 1530 anywhere in the network for simplicity. In the WISP world, I've been burned a number of times with "Jumbo" frames set on PtP radios (from more than one manufacturer) where we actually weren't passing an L2 MTU that would suppo...

Re: Flow Control, should I use it?

A very interesting topic! We have a mix of 100Mbit WiFi routers, 100Mb and Gb AP', switches 100 and 1Gb and PTP's Gb..., Flow control certainly makes sense unless you are using Gb equipment all the way from customers WiFi router..., At present we are testing flow control set to "Auto" on a section o...

Re: Minimum power settings for Mikrotik radios

Generally what are you using for links? On the links > 2km I use Jirious 25dBi dishes, > same but 29dBi. Now we also fit some ubnt dishes. On the short to medium we use either dynadish, QRT (with metal shield), Sextant (with metal shield). On the real short ones (20mtr to 500mtrs) we use some SXT's...

Re:

I do understand. As I said, my links work good nearby the zero. If you have too much selective antenna, you need to attenuate the signal somehow or change the antenna because overheating the input of the receiver makes the link problems. Strange I always thought in reception mode a low-noise amplif...

Re: Re:

.................... We found on longer run links that reducing power from full to much lower to get receive from -30's or 40's to -50 made links more stable. But on these short links its a hell more difficult to get stable link. So I am wondering if reducing power to get less overpowered receiver ...

Why would you want larger? Smaller is one of the advantages for 60Ghz.....

Re: Microstrip (flat panel) versus eliptical (disk) antenas?

................................

So I am going to gamble no on a new line of 60Ghz units hitting the market. 3-4 times more expensive as a Netmetal based links, but at least not thousands of euros anymore for other alternatives....
I have only seen a 35cm dish 60Ghz unit is there larger available?

Re: Microstrip (flat panel) versus eliptical (disk) antenas?

The statement that microstrip antennes will receive anything that can hit the front surface is wrong. The phasing of the microstrip interlink will cancel out or significantly attenuate signals coming from directions greater than a certain angle form the antenna axis, those 5 degrees cited in the fi...
