Титла: Проблем със Intel Centrino N 2230 Публикувано от: plandz в Jun 13, 2013, 21:46 Здравейте!
В лаптопа ми (Lenovo ThinkPad Edge E530),е сложена карта за безжичен достъп Intel Centrino Wireless-N 2230.Имам частичен проблем със свързването с wifi и затова си позволявам да попитам вас.ОС - Кубунту 12.04LTS.За network manager използвам wicd,защото ми е по-лесен. В нас безжичната връзка е с WPA2-PSK и проблем при свързването нямам и съм нямал никога.Проблем имам със свързването към рутера,който е на работа.Той е със свободно свързване,защото е предоставен от доставчика на интернет. Сега да опиша какво става.Ако се свържа с рутера непосредствено след зареждането на ОС,проблем няма - свързва се веднага.Проблемът се появява,ако реша да се свържа след,да кажем 3-4 минути след зареждането на Кубунту-то,или ако връзката се разпадне.Тогава свързването стига до това: "obtaining IP-adress" и толкова - там и си остава без да се свърже,докато не се терминира опита за свързване от менажера.Единствения начин,за да се направи връзка в този случай си остава рестарт-а и свързване непосредствено след него. Пробвах с външен адаптер - TL-WN821N и с него няма никакъв проблем.Свързва се по всяко време,без да създава проблеми. Все пак ми се иска да си ползвам вградения адаптер и затова се объщам за помощ към вас. Ако се искат някакви данни от мен,ще ги предоставя. Благодаря предварително за отделеното време! P.S.Свързването с този рутер от телефона ми (Samsung Galaxy SII) с андроид ОС е безпроблемно.Колеги,които имат лаптопи с Уиндоус,също се свързват безпроблемно с него.

Не съм сигурен за Убунту, но мисля, че трябва да гледаш в /var/log/messages или /var/log/syslog.
Щом свързването стига до "obtaining IP-adress", значи най-вероятно wifi-то успява да се закачи - виж дали минават изобщо някакви пакети и в двете посоки, докато чака да получи IP адрес.
