<div dir="ltr">Hi <div><br></div><div>I've checked that:<div><ul><li>IP-address on each Samsung-phone is static and correct. <br></li><li>Netmask on each Samsung-phone is correct </li><li>Gateway IP-address on each Samsung-phone is its interface IP-address</li>
<li>All Samsung-phones are connected to the same adhoc network (beside additional three Nexus-7 tablets)</li></ul><div>Note that:</div><div><ul><li>the adhoc network does not require a password<br></li><li>I have three Nexus-7-tablets run an adhoc network perfectly using the same ".conf" file</li>
</ul><div>However, I noticed that whenever I create and run an adhoc network from any of the Samsungs:</div></div><div><ul><li>each of the other two Samsungs can discover the IBSS and join it. <br></li><li>each of the three Nexus-7 can discover the IBSS and join it.</li>
<li>the adhoc-creator-Samsung can only see and ping the Nexus-tablets (I used "Fing" android-app)</li><li>any Nexus can see and ping adhoc-creator-Samsung and the other Nexus-tablets only (I used "Fing" android-app)</li>
<li>any Samsung already-joined-the-adhoc-network can't be seen by adhoc-creator-Samsung or the Nexus-tablets</li></ul><div>Hence, I can assure you that the network connectivity is fine, at least between the Samsung and the Nexus. So, I took step forward and installed OLSRD on one Samsung (which I used to create an adhoc network). the OLSRD works perfect between the adhoc-creator-Samsung and the three Nexus-7, taking into account that OLSRD didn't show any neighbor in the other two Samsung-phones who, by the way joined the adhoc network (although they can't be pinged)</div>
</div><div><br></div><div>My question is why OLSRD does't work between the Samsung-phones ? please help .. I am getting really confused </div><div><br></div><div>Thanks</div><div><br></div></div></div><div class="gmail_extra">

I would suggest not running the routing protocol until you have fixed<br>
the link issue, because it complicated debugging the situation. Check<br>
for the easy things first (ip addresses, netmasks, wifi passwords)...<br>
