I have just upgraded my internet connection. My ISP is now supplying 50mpbs. If I connect my laptop or pc directly into the ISP modem I get a speed of 75mpbs, very happy with that. But if I connect my Sitecom wl-340 router to the ISP modem and then my pc or laptop into the router i can only get 10mpbs! I have connected everything with cat 5 ftp cable. What could be the problem?
