gigabit dropped to 100mb and don't know why
Posted: Sun Apr 09, 2017 6:57 am
Ok so short and sweet, my laptop is hardwired ad has a gigabit card in it that I would always connect to my network at gigabit speeds. I noticed the movies from my NAS were stuttering and checked the network settings and all of a sudden the speed is now only 100mbps. Yes everything is gigabit in the loop and I even tried a cat 6 cable just because there are those people who think cat 5e wont do gigabit speeds (even 5 will to a degree). You have no idea how many things I read online that "experts" try to say the cable is wrong when clearly, they are. Also a ton of people said it wont work with Window 10 yet it HAS worked, just all of a sudden dropped for no reason I can determine.
Only thing shown in device drivers is - Broadcom NetLink Gigabit Ethernet.
Tried
Different cable
Different port on switch
Different switch
connected direct to main router
removed drivers and had windows reinstall
removed drivers and downloaded drivers from broadcom to try - failed badly
Checked properties in driver for speed/duplex and never showed me 1000 only 100 as options - I read online it doesnt allow you to manually change to gigabit you have to leave it on auto.
none of the above steps changed it back to gigabit speeds as I tried to copy a file each time I did something new and I was maxing at about 11mbps.
Does anyone have any ideas? I don't see that the card is bad as it has worked all these years (6 I think now) at gigabit and if it did go bad, it should just fail I imagine, not drop to a lower speed. I am about to just throw my hands up and wipe the system and reinstall windows. I hate networking!
