http://ubuntuforums.org – Hello, Since I upgraded ubuntu to 12.04 and now 12.10 I'm having wireless problems from low speeds to random disconnects. I simply can't use wireless at all since it is really "twitchy". My laptop is a SAMSUNG R580 with a realtek 8192se 802.11 b/g/n wireless PCI card. lspci -nn | grep 'Wireless' Code: 03:00.0 Network controller: Realtek Semiconductor Co., Ltd.
