I need to connect a PC to a router, but it's really far away. I just need it for internet use and nothing else. Even if I get slow internet speeds (I've got 2mbps) it is okay. What is the max length that I can use for this purpose? Google says it's around 100 metres, but I was wondering whether I could go more than this if only to use for internet purposes. My PC might be a little farther away than that (will check properly). I don't want to buy lots of network cable and find that it doesn't work.
