** Description changed: After suspending and resuming, the network adapter appears to be active (Link UP) however it is not able to properly communicate data and appears in network-manager as disconnected due to the inability to negotiate DHCP successfully. The workaround, in my case, is to execute this "fixnet" script following the resume to unload an reload the r8169 module. In 11.04 the network manager automatically reconnects at this point. imac@repo:/usr/local/bin$ cat fixnet #!/bin/sh rmmod r8169 modprobe r8169 imac@repo:/usr/local/bin$ lspci -v | grep -i realtek 0a:00.0 Ethernet controller: Realtek Semiconductor Co., Ltd. RTL8111/8168B PCI Express Gigabit Ethernet controller (rev 02) Here is a typical dmesg, showing the link up after resume (@5958) followed by my script execution (starting @ 6105).
