I have OpenELEC installed along with a Realtek RTL8188CUS wireless adapter. When pinging google.com I only get around 40-50 KB/s at max. This is the same for local where I can't stream 15MB flac files at any decent speed(I have to wait for it to buffer and getting to 15% takes around a minute). I was wondering for a while if the incorrect drivers were installed but I don't think thats it. I think it's a power problem. I would rather not buy a USB hub if I really don't need to. Maybe there are some things I can try to see if it's something else or other ways to power the USB hub better. If any more information is needed I can surely provide.
