    so..the problem as i found on many sites is that intel driver(iwlwifi or iwlagn) doesnt support AP..

    root@lemontree-Inspiron-N5010:/home/lemontree#
    modinfo iwlagn |grep depends
    depends: mac80211,cfg80211


    I still have some hope, becoz iwlagn depends on mac80211..and hostapd is said to run on such systems.

    So my this is my query:

    Is there some way to setup a wifi hotspot (not ad-hoc) using my Intel Corporation Centrino Wireless-N 1000 adapter.....?

    Can i replace iwlagn with some other driver that supports AP mode..if so, how?

    Note:
    I m using a fresh installation of ubuntu 11.10 and haven't run apt-get upgrade yet(slow connection). I tried connectify and mhotspot in windows 7 for this, and it works. But i want a solution in linux. Should i try another distro? Should i buy an external wifi adapter....?

    None that I know of.

    Yes. Google its chipset and 'master' carefully before you buy it. And, before you ask, no I don't know of one.
