    If your Directv DVRs are within your DHCP Range (for example 192.168.1.101 to 192.168.1.150) then you will have to Assign an IP Address outside of this Range so that DHCP can't reassign that IP Address when it renew it's Leases.

    Or you can use DHCP Reserved List to Assign the MAC Address of each DVR to a DHCP IP Address and then DHCP will Reassign that IP Address each time it Renews it's Leases and you will not get a Conflict or a Changed IP Address where the problem seems to arise where DHCP causes dropped devices.

    Was just mentioning it in case there was a chance someone else had done it.

    As for the "static" label, I had never noticed that before. Good catch!

    Yes, I have known about that from the Very First Time I set mine up as "Static" and when I went into the Info Screen I was Amazed that it knew that and displayed it as such.

    While that is certainly true, and the best possible advice (which I commend you and others for), I have been using "in range" static IPs for years and currently do the same (as I'm too lazy to change what is working perfectly). I have not had a single "drop" of a sat box from my MRV setup. I'm using a D-Link 825 Xtreme dual band gigabit router in a hybrid DECA/SWiM and 2nd non-DECA box. All works well.

    I am NOT recommending what I am doing. I'm just too lazy to change it and if it ain't broke, I'm not fixing it!

    Your advice is the best, but I thought I would add that it can work the other way. I never turn off a DVR, but I do turn off several netflix devices and blu ray players, all of which use DHCP for getting addresses.

    Using "in DHCP assignable range" static IP addresses is not recommended and may cause problems. It is better to do it the right way (as you and others suggest). In my case it just turns out it isn't necessary, but who knows, the next device I add could be the straw that breaks the camel's back.:)

    Where you may have an issue (using static addresses inside the DHCP pool) is if one of those devices goes off-line. When it does, the DHCP server will think that address is available and may assign it to another device. Then, when that device comes back on-line, you'll have a conflict.

    You're probably not having any issues because either those "static" devices are on 7x24, the DHCP server knows they're in use and hands out addresses around them; or when they do go off-line, no other leases happen to be expiring, so the DHCP server isn't trying to hand out any of those addresses.

    If you assign a "static IP address" to your receiver(s) that is inside your DHCP pool of address, what you can run into is another device stepping on your "static IP receiver". Meaning the DHCP server will possibly give the same IP address from within the pool of addresses you have assigned in DHCP to another device that comes onto your network.

    The DHCP server could care less about the static IP on the receiver(s) as they are not requesting IPs from the DHCP server. Therefore the DHCP server has no idea about the "static IP receiver(s)" and if a new device requests an address from the DHCP server and it just so happens that the next IP address in the pool is one of the ones you "statically assigned your receivers" then your receiver will get stepped on. The new device will receive the IP address and kick your receiver off of the network. It doesn't matter how long the receiver(s) have been powered on or powered off.

    You never should assign static IPs that are in your DHCP pool to devices. If you want your receivers to always have the same IP address but don't want to setup static IPs on the receivers then you have to use DHCP reservations based on each receivers MAC address. If you are going to use static IPs always use address that are outside of the scope of the DHCP address pool.

    I used DHCP Reservations to Assign a Static IP Address to each of my DVRs associating it with their MAC Address and I did not have any problems after that even though technically that is not a True "Static IP Address" but works just the same but if I had to do it all over again I would just Assign the Static IP Address outside of the DHCP Pool of IP Addresses and be done with it.

    Yes, I think that's exactly what is going on, or the router is keeping the used table fairly long. In any case, it's been that way for years, and I've never had a problem...never. In any case, I'm not recommending it, just noting that it is possible in some circumstances to not have a problem with doing it the wrong way. Some day when I bored, I'll go in and reserve those addresses, as that would be the more "correct" way to do it.

    I don't have to do that since I have DECA which works Absolutely Fabulously, in fact I can't tell which DVR the Recording is coming from unless I look at the UPL.

    First, thanks to everyone who responded to my previous post (#156). I don't know how to do the multi-quote thing, so I am quoting DSW2112'S post in the hope that it is most pertinent to my situation.

    I went into system setup on 1 of my DVR's and under IP address, it shows 192.168.1.109. There is no static indication. This would appear to eliminate the scenario whereby I (or someone) set the receivers up with static IP's within my router's DHCP range.

    One other thing. I just looked at the DHCP client list in the router, and now my D* boxes are listed, whereas they were not at the time I created my previous post. I guess I'll keep an eye on the DHCP list and see what happens when the lease expires.

    Thanks again for all the helpful responses

    I don't tie IP's to Mac addresses in my set-up, because I often move boxes around for CE testing. It's simpler for me to remember the IP address for each display location (FR is .201, Kitchen is .202, LR .203, etc.) So if I relocate an HR, I simply manually enter the address for that room on it's "advanced" networking tab.

    To be a little picky here, you are not assigning a static IP address to those devices. You are just telling the DHCP server to always assign a particular IP address to the device with a specific MAC address. :)

    Merg, I am so surprised at you as you are so Smart and Aware but I guess you didn't read the Whole Post as in I said it wasn't assigning a True Static IP Address so go back and read the whole post and then you will know we are on the same page of the same Songbook. :lol:

    Even us rocket scientists like to do that a bit (and networking isn't remotely related to rocket science):D

    I have been using DHCP reservations on my DVRs for a couple of years without problems. It may not work the same with all brands/models of routers, however.
