Same exact boat here. 125-150 DL, 5-10 UP on my hardwired PC connection, but only 35 DL, 6 UP on my wired PS3 connection. Have gone through the WFFC link. Have set up my router (DD-WRT) to have port-forwarding, and UPNP enabled. I did read somewhere else that some other ports should be forwarded, so I have some more as well. Would this make a negative difference?

Tried uploading images, but since I am new, the site wont let me. Maybe this will work...
