If you can receive but not transmit (as I understood from other posts in the thread, though you never answered my question about tcpdump), disabling tx checksum offloading should be the *first* thing to try, especially as there is a known bug in some RealTek chipsets which will cause tx checksums to be computed incorrectly for short packets (such as ICMP echo replies, or TCP handshake frames).
