i've installed obile hot spot but itx nt wrking on my mobile.. will any one please give me some help..

C'mon guys.
How often must this be answered?
Use the (power) search and install QTMobileHotSpot !

if power () search sent you one too many times down a lost alley, try Google with site:talk.maemo.org
Google is your friend, even (or especially?) on talk.maemo.org ¦-))))))))))))))))

what is this power search???

look for two logos, one of top of the other...
i won't say look no further, but that pretty much says it all
(no offence to Reggie (owner of the site) or adepts who mastered it, i never had the patience...)
and Google has a much better return by typed char & click

apt-get install --reinstall qtmobilehotspot

Install powernkernel and make sure your devices support adhoc mode, galaxy tabs dont for example.
