Trouble getting Intel PRO/1000 GT Desktop Adapters to show up as 1gb
-
Hi I just upgraded my pfSense box and put in 2 PCI Intel PRO/1000 GT Desktop Adapters.
For some reason I can't get them to auto-detect my 1gb lan, my other gigabit nics (2 of them) work just fine at gigabit speeds. I can't manually set the speeds on the cards either (They lose all connectivity). Both cards only detect a 100mb/s connection.
Anybody else had this problem? Comments, Suggestions?
Thanks,

Have you tried with other cables???
-
Yep - tried with other cables, other switches and to the same switches the other working gb nics are plugged into.

I'm running two Intel PRO/1000 GT Desktop Adapters on my pfSense box and they were immediately recognized as gigabit interfaces. I suggest you re-assign both the LAN and WAN interfaces manually and see if anything changes; I don't think you can simply swap them out. Other than that, are you sure they're set up on the LAN and not WAN side of things?
-
Hmm, the two interfaces on the cards are opt1 and opt2, they aren't connected to the LAN or WAN. I just had them plugged into gigabit switches to make a DMZ and WIFI networks.
I'll try swapping the cables around some more and reconfiguring and see what happens. Thanks for the suggestions.

So it turns out BOTH cables I was using were wired wrong… (these were purchased cables) The nics now show up as 1 gigabit full duplex but for some reason I can't get speeds > 99mb/s through the router. I am positive that everything is now gigabit from server -> switch -> router -> switch -> desktop (on other subnet). Has anyone seen this before where everything shows up as gigabit but the throughput is still only 100mb/s?
Thanks,

What kind of hardware are you using and what kind of trafffic are the 100mb/s for??
-
I'm using an asus p5q-e motherboard with gigabit nic to a gigabit dlink switch to the gigabit pci-e intel EXPI9301CTBLK on the pfsense box then the data is coming out of the lan nic on the router (also a gigabit nic) Intel PWLA8391GTL to a linksys gigabit switch over to my gigabit nic on my desktop. I used to get gigabit speeds when everything was on the same lan and not running through the router.
The 100mb/s was achieved by copying a 10GB file from my server to my desktop.
-
Did you measure time instead og looking at the traffic graph??
-
I looked at the BW graph as well as the transfer speed according to Windows (12.5MB/s ish) which confirms the 100mb/s. I will time a file later but I suspect it will also confirm the 100mb/s.
