I've been browsing the web to find the answer to my problem, unfortunately, I haven't found one... =[ That's why I'm here. After browsing the site, it looked like a helpful, friendly place that could just have what I'm looking for.
Ok, to the story/problem... My grandparents went out of town and are paying me to house-sit their "cottage" (basically independent home) at the retirement village they live at. I have a laptop that I brought over it's an hp pavilion dv6000 that I got back in early 2008 (runs vista). They have their own computer (Dell, runs windows 7) there as well and they also have internet. Here's the interesting thing, they have an Ethernet cable that comes directly out of the wall and does not enter a modem or router. So i unplugged the cable from their computer and put it in my laptop and everything works perfectly. Recently i purchased a new gaming desktop (runs win 7) that i plan to use in college. After a few days of staying at their place using my laptop I decided that since I'm gonna be here a while i ought to bring the desktop over as well. So I brought it over but when I plug in the ethernet cable it just says unidentified network (and underneath) no internet access. Now, last year something like this happened as well. I came over to house-sit for a few weeks during the summer and at that time all i had was my laptop. Only then, it wouldn't work on my laptop until one day when i plugged it in and it magically started working (i have no clue how or why). But then when i left it wouldn't work on their computer and they ended up having an IT guy come fix their problem.
My thoughts... So I think the problem might have something to do with the Cache. The only problem is, since there's no modem or router or anything i am unable to restart it and clear the cache. I'm thinking maybe there's some way to manually clear the cache somewhere in command prompt or maybe some other way. Maybe it has something to do with the fact that it's different windows versions. Or maybe my laptop is just evil and likes to hog all the internetz.

If anyone is still awake after reading my wall of text, kudos. I hope my problem is clear and I hope I supplied enough background information (i also hope i didn't bog it down with too much info...). If Anyone needs clarification I will be checking in periodically and will be happy to clarify. Also, if pictures are necessary i can provide them, but i would prefer a solution that doesn't need me to post pics.
