FS#763 - No IPv4 DHCP address are issued on LAN #5875
Comments
marconi: Update : I got the other GL-AR150 ("dev1" in the table above) to show the symptom. Here's a clue : if I do "/etc/init.d/dnsmasq restart", then it works OK. |
marconi: Update : network.lan.ipaddr=192.168.2.1 doesn't always fix it . "/etc/init.d/dnsmasq restart" always fixes it. I suspect a race condition. Dunno why I've only seen it on the GL-AR150. |
por: When another DHCP service is running on the same LAN, then /etc/init.d/dnsmasq will not start DHCP on that LAN. So, are you sure no other device is serving DHCP on your LAN ? |
Bluse: HI, I discovered a similar issue where the dhcp range is empty in the dnsmaqs config I opened a tickert for this [1] Greetings Thomas |
marconi: I just saw this on a "NETGEAR WNDR3700v4" as well : no IPv4 address issued. Strange. Perhaps it's some kind of race, because it's intermittent. I got in on the "link local" IPv6 address, and found no "dhcp-range" in /var/etc/dnsmasq.conf.cfg02411c I changed a few things (hostname, turned on radios, etc), and rebooted and now it's issuing IPv4 addresses. BTW, to calculate the "link local" IPv6 address, use "RFC4291 Appendix A". |
bjonglez: Can you try with lede 17.01.2? dnsmasq got a few updates since 17.01.1. |
marconi: I tried LEDE Reboot (17.01.2, r3435-65eec8bd5f) on a "NETGEAR WNDR3700v4" and it issued IPv4 addresses OK. I also tried 2 gl-ar150 routers, and they issued IPv4 addresses, so maybe it's fixed... |
marconi:
This is a strange one : I installed "LEDE 17.01.1" on a GL-AR150 , and when I plugged into the LAN port, it didn't give me an IPv4 address. I got in on an IPv6 address and found that /var/etc/dnsmasq.conf.cfg02411c didn't have a "dhcp-range" entry.
Strange. I did network.lan.ipaddr=192.168.2.1 , and rebooted and it issues IPv4 addresses.
"LEDE 17.01.0" worked fine on this GL-AR150
More strange is that I have another GL-AR150, and it works fine on that. The only difference is that the broken one has a POE module (but that's on the WAN port).
Supply the following if possible:
GL-AR150
"LEDE 17.01.1"
All I did was install "LEDE 17.01.1" on a GL-AR150.
Here's a little table of what works and what doesn't :
"LEDE 17.01.0" on dev0 => works OK "LEDE 17.01.0" on dev1 => works OK "LEDE 17.01.1" on dev1 => works OK
"LEDE 17.01.1" on dev0 => no "dhcp-range" in /var/etc/dnsmasq.conf.cfg02411c
"LEDE 17.01.1" on dev0 , network.lan.ipaddr=192.168.2.1 => works OK
