Re: Wrong ethernet speed negotiation [SOLVED]

You use gigabit POE injectors? Its the white ones with the green led... That's an excellent question... Just checked... the poe injector has only 4 wires !! no green led. this one was shipped with the antennas... does it mean that mikrotik sell gigabit capable antennas with 100Mbps injector ? that'...

Re: Wrong ethernet speed negotiation [SOLVED]

Stupid question: is interface on Site B configured to advertise 1000M at all (have needed options ticked)? Yes it is ;) on site B, the LHG don't advertise 1Gbps, that's strange. Remember only the AC type LHG can do 1G, the N type is 100 Mbit. You also have to use the power inserters that come with ...

Re: Wrong ethernet speed negotiation [SOLVED]

You mean interferences going to the cable ? in my case both site are domestic area, without strong interferences on site B, the LHG don't advertise 1Gbps, that's strange. Cable on both site are not from the same manufacturer, so i excluded a problem on both cable at the same time Cable on site A is ...

Re: Help me increase quality of this 3km link

Hi Try 40MHz (or 20Mhz) channels. A stable 40Mhz or 20Mhz link is better than a flaky 80MHz. using 802.1 20/40/80 Mhz : 106 Mbps with lot of drops 20/40 Mhz: 85 Mpbs with lot of drops too. 20 Mhz: 55 Mbps with lot of drops so changing it does not remove drops. also, i would expect to get 100 Mbps wi...

Re: Help me increase quality of this 3km link

Hi Thanks for the answer if by LOS you mean "can you see the other antenna" : yes (even if i need magnifier) if you mean "does the fresnel is completely clear": i'm really not an expert, i don't know the "size" of the fresnel area, i think no. (see edit on the bottom for pictures) i installed both a...

Re: Do you think i can achieve this PTP link with 5ghz ?
