I'm running an Asus RT-AC87R as my router, took the RT-AC66U setup as an AP off my network because of compatibility problems, but I looked in my syslog today and this is all I see:

I didn't want to post all of them because it would fill up the entire thread. It looks like 2 devices are having problems getting an IP address. I have the router setup to use DHCP for an IP range of 192.168.1.15 through .256, and I have some devices setup to use static IPs between .2 and .14 so I should have enough IP addresses available for everything on my network to connect. Does anyone have any suggestions or maybe have seen this before? I'm using Merlin's 376.49.5 firmware. I'd appreciate any input/suggestions. Thanks.
 
DHCP range through *.256? The max is 255 but that is usually used for netmasks. 254 is the usual max for assignable IPs.

Try changing the range to *.15 through *.254
 
I suspect RT-AC66U is connected to ISP with no firewall and now it is acting as DHCP server for whole ISP segment.:)
 
Fix your DHCP scope (254 is the highest valid number), and upgrade to 378.50 (there was an issue with the max DHCP lease calculation in 376.49).
 
I Experience the very same issue with Fw Merlin 378.55 my range is *.2 - *.254 sending some sample lines

Hey everybody, I have recently upgraded to a Time Warner cable 350 Mb by 25 Mb connection… I had been running and 87Uas strictly an axis point downstairs, but I needed to hook up as a router in order to get my full band with because I needed to bypass the CPUs useful hardware acceleration CTF plus AF...otherwise if I did not use both in combination, I could get 350 Mb down through one connection but the instant more than one connection try to pull a lot of data, the CPUs would max out and I would only get about 100 Mb total throughput for all my connections… Anyway the 87U has been running fine for the past few weeks and now I'm semi-been getting the logs filled up with all of it's weird DNS request by what looks like Mac addresses but they are too long and do not make sense to me

ASUS RT-AC87U Is the Full model number of my router, and the cable modem is running in Bridge Mode… With 16 downstream channels and for upstream channels... Everything on that cable modem is completely disabled so it is a pure network bridge as if it were NOT a cable modem/router/Wi-Fi access point combination , But just a plain old cable modem that bridges coax to 1000 Mb ethernet

Here is a snippet from my logs right after I disabled my WAN in Port and reenableD IT

The above is the spam that I started getting just a couple weeks ago… Actually it was just a week ago, but thinking about it, I switched my IP six from one mode to another... Currently I'm running and stateless mode call which lets the ISP server give me a prefix and then my IP DHCP server gives out the addresses '
Before I got this spam I was running and state full mode. only difference in the other mode is that I am given a block of IP version six addresses, and I can specify the range that I would like to use, and my local dchp Gives them out

Wondering if my switch to stateless mode is causing some bazaar things to happen... Because technically it's stateless mode you don't even need a DHCP server in your house whatsoever… If your ISP has a DHCP – PD like mine does, you don't even need a DHCP server in your house, every device gets its own public IP address… Which the consumer is router can still firewall ... And NAT does not exist in IP version six... Oh it's very important to enable and IP six firewall which I have done on my router
 
MY NETWORK/LAN TOPOLOGY AND DETAILS:

I am providing this information, in case someone sees something wrong with my network LAN topology that could be causing this issue

I have a backbone throughout my house, and it is not a redundant backbone because in order to use the full acceleration of the 87 router, spanning tree protocol must be turned off which means you may not have any loops in your ethernet. I have a fat phone throughout my house, and it is not a redundant backbone because in order to use the full acceleration of the 87+ router, spanning tree protocol must be turned off which means you may not have any loops in your ethernet plug Suffice to say my Internet and yours into my upstairs office and the 87 unit only has one cat seven cable going into an eight port hub from it, and that eight port hub deals with everything in the office and runs to a five port hub in the bedroom next to it. Suffice to say my Internet and yours into my upstairs office and the 87 unit only has one cat seven cable going into an eight port hub from it, and that eight port hub deals with everything in the office and runs to a five port hub in the bedroom next to it. From that five port hub only two ports are used in one goes the master bedroom and living room… In the master bedroom is another 5 po five port hub only two ports are used in one goes the master bedroom and living room… In the master bedroom is another fivr port Hub. Attached to it is my main DirecTV DVR, a third-generation AppleTV, and older Asus router in acess point only mode (56u), and lastly and android and video shield TV device so I can stream games from my PC to my HDTV in my master bedroom

So backing up to the room before the master bedroom… The other port on the leadsof the living room, and in the living room is an eight port hub... One of those ports is connected to An RT-68U model in access point only mode… Up until a month ago that was my main router, but I only had a 55 x 5 Internet connection at that time… And that router was able to handle that

Anyway attached to the 8 port downstairs is my second DirecTV DVR, ps4, Xbox one, PS3, A generation three Apple TV, streaming camera so I can watch my dogs and cats sit on the couch while I'm away , an Xbox 360 ... Some of these are plugged into the access point… Actually only one of them are

just to make everything clear all hubs are switching Hubs and are identical and they're all net gear. All cables are category seven – even the ones that run outside of my house to my master bed room and living room. Wow each of you can handle 1000 Mb full duplex per port, each hub has it internal bad with 10 Gb...that way I can have multiple 1 G that way I can have multiple 1 Gb Data transfer is going on providing they do not attempt to happen on the same physical wire… However the connections connecting the three parts of the house are limited to one gigabits per second. Are used category seven cables so all I have to do in the future is replace the hubs with 10 Gb hubs to go at 10 Gb ...of cose those speeds are limited by the devices network ports speed (for example all Apple TVs generation 1 to 3 have only 100 megabit reports). Their Wi-Fi is only 802.11N with one channel. Even though it's TopSpeed over Wi-Fi is 144 Mb, I found that 100 Mb wired is much more stable because i even though it's TopSpeed over Wi-Fi is 144 Mb, I found that 100 Mb wired is much more stable because it's FD VS HD … As all Wi-Fi is up duplex except AC and the upcoming … As all Wi-Fi is up duplex except AC and the upcoming A.D.

Anyway the reason why I listed my whole network topology is just in case someone could see something wrong with something that I did that would cause any of this… But all of this topology has been in place for nine months, and I've not gotten these entries and my routers log anyway the reason why I listed my whole network topology is just in case someone could see something wrong with something that I did that would cause any of this… But all of this topology has been in place for nine months, and I've not gotten these entries and my routers long
