I should have posted in more detail but I only had a towel on (shower). I had ten minutes to type the message, get dressed, then go to work. O.K. here goes.
I'm currently at a home computer with only one computer connected to the network at the moment and a router (Linksys BEFSR41 V.2)
Two days ago I noticed nasty tangled wires and ethernet cords that weren't even in use connected to the router. So I unplug all the ethernet cords, roll up the unused and left enough for my pc - router - cable box. Upon booting up the computer I was getting the hassle that i didn't have internet connection. So I made the direct connection from pc - cable box. Net worked fine. (That's dandy.)
Well, I still wanted to use the router for security purposes so, later I try hooking it back up. It works! yay. One problem... Somehow i still get net through the router but my pc's network card is using the direct isp's IP. It's not giving me a 192.168. I'm getting a real ip address. I can't seem to make my router want to give me a 192.168. and when it does give me an internal ip i don't have internet connection but i can connect to my router.
My mac address on properties in my network card has different mac address then on command prompt when i type 'arp -a'. I'm not sure if that matters.
If you could dumb down how to enable STP or a good tutorial, I'd be appreciative. I just started my first semester in IT for network engineering. Not far enough in it yet
A rogue? aka botnet? I'm pretty sure the arp request are internal? I have no clue how arp poison/spoof works. maybe i set myself out for bait for not using a router for awhile. If you need more information please ask!
edit: !!! I think it makes since. I messed it up once I started unplugging the router. It's still trying to find the missing device that i detached?? but why couldn't i get net through the router? argghghghhh
