== Identify the problem ==
To help you identify a network problem you might have, try using the [http://netwww.pommepauseamahi.com/network_troubleshooter/ net Interactive Amahi Network Troubleshooter].
If it fails along the way, it will give you instructions on how to get additional help, and how to provide us with the information we need to help you understand and fix the problem.
== Additional troubleshooting Diagnosis ==
<b>It If the [http://www.amahi.net Interactive Amahi Network Troubleshooter ] can't help</b>, you can try the steps below, and tell us (on IRC, or in the forums) what step you get stuck at.
=== Step 1 ===
From your hda itself (via ssh or at the desktop in a terminal), can you:
# ping hda <small>(it should ping the IP of your HDA; this ensures the dns server is working)</small>
# ping router <small> (it should ping the IP of the router; this ensures your HDA can see the router)</small>
# ping 688.1808.2068.184 8 <small>(this ensures you can see the rest of the world)</small>
# ping yahoo.com <small> (this ensures your dns server can see the world)</small>
# Access <nowiki>http://hda </nowiki> in a browser (or use curl in a terminal)
If the above does not work, try and fix it by double checking the settings.
After the above works, you should be able to access
<code><nowiki>http://hda</nowiki></code>
from the HDA machine's desktop!
If the above works, '''then and only then''' you may turn off the DHCP server in your router. '''IMPORTANT: after turning off the DHCP server in our router, you must [[RenewIP|renew your client's IP addresses]].'''
== Step 2 =='''IMPORTANT:''' after turning off the DHCP server in your router, you must [[RenewIP|renew your client's IP addresses]].
Then === Step 2 === If you want to use the full functionality of your HDA, you '''must make sure your client has a DHCP lease from your HDA''' from here on, so let's move to one or more of the clients (after their network has restarted:
# ping hda <small>(this ensures the client can see the DNS server in your HDA)</small>
* At what point, relative to the above, did you restart (or ''release and'' renew the DHCP lease on the) clients
== Non Default Network Set-ups ==
If your router does not have an IP of 192.168.1.1, the following command will make the process easy to allow your HDA to work:
su - hda-change-gw [gateway IP]
[enter root password]Example if your default gateway (router) has an IP of 192.168.0.1:
hda-change-gw [gateway IP] 192.168.0.1
Example if your default gateway (router) has an IP of 192.168.0.1:

Note: You will need Refer to restart your server after applying the changeApple [[Airport express|Airport Express]] guidance for a work around.
This same technique may work with other router brands.

In some cases, it could be the client OS causing issues.
One known issue is the [[Vista_Networking_Issue|Windows Networking Issue]]
