You are not alone. I am experiencing the exact same issue with Feisty Fawn Beta (With updates applied bringing it to nearly-released status)
The card is a PCMCIA "Generic" re-branded device from wal-mart. It is detected as : PCI Device: Realtek Semiconductor Co., Ltd. RTL8180L 802.11b MAC (rev 20) Subsystem: Linksys unknown device 0019 The r818x driver works ok but auto-configuration sure doesn't! As long as I put an extra random digit on the end of the essid (or provide the router's mac address via iwconfig) then I can establish a network connection immediately. I'm not sure if this is a problem with iwconfig or the device driver but it seems more likely to be the device or the r818x kernel module. ** Tags added: essid iwconfig r818x rtl8180 rtl8180l -- iwconfig lost the last letter of essid when using r818x driver https://bugs.launchpad.net/bugs/98926 You received this bug notification because you are a member of Ubuntu Bugs, which is the bug contact for Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
