WRTP54G: Should and can I upgrade from firmware 3.1.16 to 3.1.17

    My WRTP54G came with firmware 3.1.16-EU and is unlocked. My current firmware has one problem for me: the router doens't send a hostname to my ISP, so I won't get an IP-address (I could check this in the log files of my linux server).

    Does anybody know the difference between firmware 3.1.16 and 3.1.17?

    And can I install the 3.1.17 for the WRTP54G-NA on my WRTP54G-EU version 1.1?

    Any help is appreciated.

    I contacted Linksys today and it's safe to upgrade the unit. The difference between EU and NA firmware is the number of wireless channels (the NA has less). It doens't matter if you have HW version 1.0 or 1.1.

    My upgrade went without problems. However the DHCP still has problems to send the hostname. Are there others, who are able to check if they WRTP54G is able to send a hostname on the WAN port?
    (I checked it in the file /var/lib/dhcp/dhcpd.leases with my Debian server)

    Offtopic: would you recommend to switch the WRTP54G for an WRT54GP2?

    EDIT: what Linksys said about the number of wireless channels is not true! I still have the same number of channels.

    That's a piece of good information.

    Does a DHCP client support a hostname to send to the DHCP server?

    WRTP54GP2 is an RT31P2 + WiFi. An RT31P2 is not better than an RTP300. That said, it will be a big mistake to downgrade from a WRTP54G to a WRT54GP2, YMMV.

    Normaly a DHCP client sends its hostname in the DHCPDISCOVER packet to the server. In the example below you see a part of the DHCP leases file of my Linux dhcp server:
    Code:
    lease 192.168.0.103 {
    	starts 3 2006/09/13 22:45:39;
    	ends 3 2006/09/13 22:55:39;
    	hardware ethernet 00:30:1b:07:61:7d;
    	uid 01:00:30:1b:07:61:7d;
    	client-hostname "Shuttle";
    }
    lease 192.168.0.101 {
    	starts 3 2006/09/13 23:52:15;
    	ends 4 2006/09/14 00:02:15;
    	hardware ethernet 00:18:39:51:a4:ff;
    	uid 01:00:18:39:51:a4:ff;
    }
    As you can see, my PC sends its hostname Shuttle to the server. The other request is of the Linksys router, which doesn't send a hostname :frown:

    Is there any drawbacks of not having the DHCP server sending the hostname to your WRTP54G router? BTW, how many WiFi channels do you currently have on your WRTP54G with the -NA firmware?

    Maybe I was a little bit unclear. The problem is if you have an internet provider, which gives you an IP based on your hostname. My Dutch provider does this. In case the Linksys router doesn't send the hostname (provided by the ISP), it won't get an IP back.

    The channels were the normal number channels for non-US: 1 to 13.
