    Repeater DHCP Issues

    Well that's ok, it gives me one more place to throw a USB drive, setup entware, tcpdump, and go to town :D Getting the full picture and tracing root cause will hopefully help out everyone with more complex setups.

    Repeater DHCP Issues

    Sorry about that, it is as follows: Living Room Echo A0:02:DC:DF:A0:8F 192.168.50.19 LivingRoomEcho Interesting part is that this Echo has a Manual Assignment in LAN\DHCP Server settings and does not show in the General Log, Wireless Log, or DHCP leases section. The AP shows the Echo...

    Repeater DHCP Issues

    Ok, for those knowledgeable of pcap troubleshooting, the problem persists, even following the WPAD setting adjustment. I currently have an Amazon Echo that will not obtain an IP address, surprisingly even after restarting the MB this afternoon. The following link contains 4 pcap files, cap1 is...

    Repeater DHCP Issues

    Time will tell if this is a factor, but when adding a USB, I went to Tools\Other Settings rather than Administration\System, which I do far too often mixing them up mentally. In there, I had adjusted the setting, "dhcpd: send empty WPAD with a carriage return" to Yes when configuring from a...

    Repeater DHCP Issues

    For the benefit of anyone else also trying to capture this, here is what I used (note that my sda1 label is entware, thus the duplicate name in path); I found that the first /tmp is not required and if included gives a path not found error: tcpdump -i any -vvv -s 1500 '(port 67 or port 68)' -w...

    Repeater DHCP Issues

    The / tee command isn't writing a file and -w dhcp.pcap doesn't seem to be creating a file either. I'm getting closer to getting capture data, but this isn't my primary foray, so I'm learning on the fly.

    Repeater DHCP Issues

    Well I have tcpdump loaded on the router, but the first capture I initiated was a bit overwhelming :eek: and didn't break from displaying everything from terminal. Is there a basic capture that would cover only DHCP requests to limit the volume of information? tcpdump -i any '((port 67 or port...

    Repeater DHCP Issues

    Looking at the WS capture, I see a plentiful amount of DHCP Discovers occurring regularly. Following a restart of the MB, the Discovers still occur, but there are matching DHCP Requests with the same transaction ID that have the requested IP address. It appears that when the issue occurs, the...

    Repeater DHCP Issues

    Laptop is connected to the AP and has IP, mobile failing to obtain IP from the same AP connection. Wireshark monitoring from the laptop, so seeing the broadcast on the network.

    Repeater DHCP Issues

    Ok, my mobile device is currently having this issue after coming back from lunch. In Wireshark, from my laptop, I see many DHCP Discover captures without a response being received. Bootstrap Protocol (Discover) Message type: Boot Request (1) Hardware type: Ethernet (0x01) Hardware...

    Repeater DHCP Issues

    Edited my post, including the horrible version mistake I made typing from mobile while watching a movie last night. Realized that I need to test further and failed to finish the sentence :oops:. I loaded up Wireshark and now just need to wait for it to occur again.

    Repeater DHCP Issues

    Did so from the router perspective following the update to 384.6 and also disabled the 2.4GHz and first 5GHz network on the AC3200, which removed most devices, but (realized that I need to test further and failed to finish the sentence :oops:). I'll fire up Wireshark the next time it occurs on...

    Repeater DHCP Issues

    Yes to all of the usual suspects. Have reset enough to be confident that devices and routers have no ghosts in them. This includes changing the router SSID that the MB connects to with the bare minimum connections (MB, an Echo, and FireTV), and changing out the MB in question. Not to be lost...

    Repeater DHCP Issues

    With the issue occurring on my Galaxy S9+, it will continuously attempt to connect between the three SSIDs on the AP (AC3200), so this is on 2.4GHz and both 5GHz channels, but displays "Failed to obtain IP address." On the AP, I also show it's connection in Wireless log while attempting to...

    Repeater DHCP Issues

    I will need to test further, but have seen where assigning a static IP does work, e.g. my scope is set to a max of 250 on a /24 leaving some free addresses for use and when manually setting to 252, I can access ping devices on the network. I think there may be some routing "challenges" still...

    Repeater DHCP Issues

    At least from the client perspective, they never received an IP address; displaying the generic 169.x.x.x instead of the local IP expected; this is true if they were previously assigned an IP and showing in the router DHCP reservations table as well.

    Repeater DHCP Issues

    FYI, I have been battling this same issue for some time when using a router (e.g. RT-N66, RT-AC66, RT-AC68) in media bridge mode. I didn't see this issue when using a dedicated media bridge (EA-N66), however it limited the functionality of the network such as parental controls, MAC address...

    RT AC3200 limit on the number of 2.4GB clients?

    I have the 384.6 Alpha2 build on three routers now, AC86U (router), AC68P (media bridge), and AC3200 (AP) across a large network span with >30 devices connected and was having nothing but problems with 384.5, especially when my son's iOS devices came home from school (all Android/Windows...

    [Preview] Early Asuswrt-Merlin 384.6 test builds are available

    @RMerlin I am happy to report that I am not seeing the frequent network loss that I was on 384.5 with the latest Alpha after a reset. As noted earlier, I did need to disable DNSSEC, however clients were frequently losing network connectivity on the prior version, especially when my son's iOS...

    [Preview] Early Asuswrt-Merlin 384.6 test builds are available

    From the logging I was seeing SmartThings performing queries, but never getting a response. These were going to the router, which is advertised as the DNS server, so it's not clear why the response was not being received unless it was ignored. My client could lookup the same entry and resolve...
