<p>Hi all,</p>
<p>I have an issue trying to set up an encrypted mesh network using
USB modules mounting Ralink RT5390 chipset (RT2800 driver).</p>
<p>I use OpenWrt CC with mac80211 package updated to September, 29th
commit.</p>
<p>Using wpasupplicant_mesh or authsae I have the same behavior:
nodes establish the plink but thy can't ping each other. Sometimes
some pings work and then no more. Mesh without encryption works
fine.<br>
</p>
<p>1) I tried to load RT2800 module with nohwcrypt=1 and nothing
changed.</p>
<p>2) I tried applying a patch found on the internet, modified in
order to work with the newer compat-wireless style:</p>

<p>but nothing changed.<br>
</p>
<p>3) I checked if could be an ARP problem, make the nodes to send
an ARP broadcast announce every second, but nothing changed.</p>

</p>
<p>Could someone help me to solve the issue or give me a hint?</p>
<p><br>
</p>
<p>Thank you in advance,</p>
<p><br>
