    Hello all. I have an HR-21 receiver that I hooked up to the internet a couple of months ago. Everything went well and it connected just fine. Recently, I installed an infrared controller to my router (WRT54G) so that I could build a third party remote using my iPad. The IR controller is not used to control the HR-21. The HR-21 box is controlled through its ethernet port using HTTP commands on third party iPad software called iRule. Everything works great. I can control my DVR with the iPad using the iRule remote software. I can also control the DVR using DirecTv's own iPad app. The only problem, is now I cannot get the DVR connected to the internet. I've double checked and triple checked the wiring and everything can be detected on the network. The modem is plugged into port 1, the DVR, port 2, and the IR controller, port 3 of the router. They are connected with standard cat5e straight cable. I have excellent (and fast) internet connection on my PC that the modem is attached to. Does anybody have any ideas?



    Thanks.

    Check to make sure that the DVR has a valid IP address that has been assigned by your router. It it is correct and it still spear work, use DHCP with a manual address outside of the range set by your router.

    Thanks, Kevin. The address that my router assigns is 192.168.2.100. It's a valid address as I've got full control over the box using the iPad app. The box will respond to pinging and it shows up on my LAN map. I just can't get it connected to the internet. My router starts assigning at 192.168.2.100. Even though I manually enter an IP address in the DVR's advanced setup screen, when the box is re-booted, the router will assign it a new IP address (192.168.2.102)

    In the DVR's connection status screen, it shows:
    Network = connected.
    Internet = no connection.

    I wish I understood DHCP, IP addressed, reservations, assignments, static addresses, etc.

    I'm having a similar issue with net connectivity after the 458 update about a week ago on a HR20i. I posted about it in detail in the HR20/21/22/23/24 & R22 (National Release) - Issues Discussion thread. Note that my receiver can see devices on the internal network, but just complains about getting to the outside world, as shown in mborner's status report above. I think that they might have changed how they determine what constitutes "connected".

    Go to the network settings and list for us :

    The IP address
    Mask
    Gateway
    DNS

    It should be something like:

    192.168.2.100 (the 2 will vary with your network)
    255.255.255.0
    192.168.2.1 (router address)
    192.168.2.1 (or a valid external dns - like opendns)

    Dennisj00, my network settings look exactly like that except that DNS is
    192.168.2.100

    An incorrect DNS would kill any internet traffic that's not specified by IP.

    I assume this is set by DHCP? Change the IP to something outside the DHCP range - possibly .99 (Linksys default is generally 100 to 150.)

    Check your router - or change the dns to .1 on the HR and try it.

    Actually, just change the DNS to be the same as the router. Most routers will then pass the DNS request on through to the cable/DSL modem, which has the actual DNS information.

    Every device on my system is .2. I know the default IP for the router is .1 but one day my internet stopped working and technical support (Bellsouth) said to change it to .2 and it worked. I don't know what they did but it was .1 for years with no issues. I've tried going back to .1 but it doesn't work. I asked them what they changed to make my router have to change its IP address and they said I was mistaken, my router should have been .2 the entire time. I didn't want to argue.

    As Merg and I said above, change the dns to be the same as the router . . . test it and then reboot if it works to see if it keeps the change.

    If it doesn't keep the change, change the ip to an unused ip (like .2.99) and the dns to .2.1 and again test and reboot. It should keep those settings.

    The linksys WRT54G has a default IP set up that Looks like this: (unless you have changed settings)

    Router IP 192.168.0.2
    Sub net 255.255.255.0
    Default Gateway 192.168.0.1
    DNS 1 192.168.0.1
    DNS 2 ??????????? can be any thing, usually from the ISP provider

    IP Starting address 192.168.0.3
    Number of connections Usually 10

    This will assign 8 IP address's to device's in your home.

    If you changed the addressing to read 192.168.2.100 as the main IP then you need to go with those settings, BUT DO NOT CHANGE THE DNS 1

    I've owned quite a few WRT54G routers and they all defaulted to 192.168.1.1 for the rotuer IP address. The default gateway is also should be the same as the router IP address.

    As for the default starting IP address for DHCP, I believe it was 192.168.1.100.

    As for DNS, once again the default will be the router IP address. What this tells the router is that it should look to the modem for the DNS information which is passed down to the modem via your ISP. You can, of course, put in your own DNS IP addresses if you want to.

    The Merg and dennisj00, problem solved. Thank you for your suggestions. My routers DNS servers were incorrect as well as the DVR's. I also changed IP assignments to start at .110, as was suggested. Thanks again. :)
