My school has like a 480Mbps connection and I have a few times pulled the Gigabit Ethernet cable out of the computers in the computer lab and plugged it into mine so i can download full speed. I started to download my steam account there and i got BF:BC2 done in 8 mins. They ended up close so i came back today and now I connect the Ethernet cable and it disappears in 30-60s no matter what i do it wont come back. I tried in several computers and all the same the Ethernet disappears and wont come back on my computer or the original computer it was plugged into. Does anyone hear got any ideas on why and how this happens? I have never seen an Ethernet connection completely disappear where you can't even see it. Also worse case is there a work around where i can bridge from the lab computer to mine or something? Thanks for your help. I hope I can get this figured out because it'll take ~144 hours if i use wifi compared to 21 hours tops :/ I get 3MBps average on wifi and range from 10-50MBps on Ethernet and average ~20MBps

Maybe a MAC address filter?

What could it be though keeping me from using ethernet? at least help me figure out what they use don't need to tell me how
I'll figure that out on my own. Who says its a security messure anyways....it could be a glitch
Anyways too you think they would use that? They probably have a 1000 computers their....wouldn't that be a pain to set up and too time consuming? and how would they do that in 2 days? super IT team? Also does MAC filter take 60s to work?
PS a simple google search gave me a huge walk through with all the files and pictures too! I am just curious on what they use and what could cause this....its very weird that it happened in two days and i have never seen this before so i want to learn! DL don't take my learning experience away!!!!! -
MAC filter would be impractical and it wouldn't work like what you describe.
You would never get an IP in the first place- no disapearing after 30 seconds or so- just no connection at all. -

i pulled it out from a computer though that already had a connection so how long would it take for it to register? What could it be if thats not it...i find it weird it works for 30-60s and disappears...you can't even see it and it won't register at all as if the cable was dead. Then when you connect it back to the computer lab PC it says some server error message saying server can not be reached or something. Would that message be helpful?

More like their lousy router/server config and windows software problem. Try use the repair connection from windows or restart after you plug the cable in.

nope the trouble shoot doesn't do anything...says you need to plug in network cable. So maybe plug in when computer is off and turn it on from there?....seem a little hokey to me
-
could be an auto-sensing switch or router noticing the change and dumping the IP address on that lane after 30 seconds. we have managed switches/routers at work that assign IP addresses by the port not by device, and if it sees a MAC address not in the database it dumps the lane ( switch port ).
in which you would need permission from the IT dept and your MAC added to the list. -

no very practical and simple to implement with the right infrastructure

not really, my husband is the network person and has just taught me the basics on some of this stuff. If he has time I will have him post up some of the basics, or if your big on reading find a network administrators guide for cisco or netgear managed routers and switches.

well now i know where to google...Also they didn't stop what i was doing just using gigabit. I do the exact same stuff over wifi...the data is not the issue. They due use IPv6 though. Over the week i'll google those terms and read up on those concepts
EDIT:
yea i just quickly skimmed those terms and NAC is the only real useful one. I'll due some testing over the next few weeks. I am doing to try the usb ethernet and MAC address filtering first to see if that is just what they are doing or more. I will let them know though if i find a hole since they closed off just plug and play ethernet it is obvious that they don't want that to work. ^^ odd though how it worked two times for several hours in a two week period......lazy IT people lol. -
My money is still with your school IT though.

BTW tried once with the usb ethernet and no cigar....USB ports seemed to die after plugging it in but i'll try again next week i think over break
Need help with GB network disappearing at school.
