I have a weird problem I don't understand. My home network consists of a modem/(wireless) router connected to the internet (CBN SVG6540E, slightly modified by my provider) on the groundfloor and a wireless (B/G) router configured as Access Point (Medion 40900) on the first floor. This AP is wired to the modem/router and has 4 fast-ethernet wired ports. This all works except that when I use my laptop I get an internet connection of about 20Mbps wireless and about 8 Mbps wired (upstairs). Downstairs, wired to the CBN modem, I get about 35Mbps. I tried the wired connection with another computer: same result of about 8 Mbps upstairs. Can anyone explain this? It seems that I'm losing speed on my wired connection upstairs, though it connects through the same AP!
