i have 2 LHG G-5acD-XL connected through nstreme.
each LHG is connected to a 1Gbps switch using cat 6 cable.
Cable are tested and OK
But on both sides, the ethernet is running at 100Mbs full duplex rate
system are up to date. (6.45.6 package version & firmware)
on site A, i see that the LHG advertise 1Gbps but “link partner” is advertising 100Mbps
On site B i see that the LHG advertise only 100Mbs, and does not advertise 1Gbps
changing Switch does not work
setting auto neg to off and forcing 1Gpbs does not work (thanks “safe mode”)
do you have an idea ?
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 30 meter long
cable on site B is 40 meter long
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 it, not some leftover type from another device.
On site B, if i uncheck then re-check the 1Gbs checkbox, i see in the status that the LHG advertise 1Gpbs. 5 secondes later, it’s gone, and i only see 10/100 half/full
Edit: resetting device does not help
Tried to downgrad without success.. last this to do is to check both cables…
1 is cat 5e, the other is cat6
if it’s the cable, it’s really bad luck having 2 new faultly cable
we bought LHG 2Ghz before, and we replaced it with 5Ghz AC antennas, without replacing the injector…
i found the good gigabit poe injector and installed it on site 1 : now it’s giga
i must install it to site B
thanks for finding it Zacharias
