Error: no address range available for DHCP request

Installing and Using OpenWrt Network and Wireless Configuration
1

Hello all,

I am having an issue where I am unable to connect to the wireless on one of my connetions (RGMedia). I have been using this post as a reference:

https://www.google.com/url?sa=t&rct=j&q=&esrc=s&source=web&cd=3&ved=2ahUKEwj3hZ6e3K7fAhUEP60KHdNwDV8QFjACegQIAxAB&url=https%3A%2F%2Fforum.openwrt.org%2Ft%2Fcant-get-dhcp-lease%2F4885&usg=AOvVaw2miteB31oYpeIn2n8I0L8n

However, I believe that my case is not the same. Any ways, here is my configuration and logs for the DHCP

# Change the following lines if you want dnsmasq to serve SRV
# records.
# You may add multiple srv-host lines.
# The fields are <name>,<target>,<port>,<priority>,<weight>

# A SRV record sending LDAP for the example.com domain to
# ldapserver.example.com port 289
#srv-host=_ldap._tcp.example.com,ldapserver.example.com,389

# Two SRV records for LDAP, each with different priorities
#srv-host=_ldap._tcp.example.com,ldapserver.example.com,389,1
#srv-host=_ldap._tcp.example.com,ldapserver.example.com,389,2

# A SRV record indicating that there is no LDAP server for the domain
# example.com
#srv-host=_ldap._tcp.example.com

# The following line shows how to make dnsmasq serve an arbitrary PTR
# record. This is useful for DNS-SD.
# The fields are <name>,<target>
#ptr-record=_http._tcp.dns-sd-services,"New Employee Page._http._tcp.dns-sd-services"

# Change the following lines to enable dnsmasq to serve TXT records.
# These are used for things like SPF and zeroconf.
# The fields are <name>,<text>,<text>...

#Example SPF.
#txt-record=example.com,"v=spf1 a -all"

#Example zeroconf
#txt-record=_http._tcp.example.com,name=value,paper=A4

# Provide an alias for a "local" DNS name. Note that this _only_ works
# for targets which are names from DHCP or /etc/hosts. Give host
# "bert" another name, bertrand
# The fields are <cname>,<target>
#cname=bertand,bert

Hello all,

here is another data point. When I reset the radio on RGMedia, the DHCP server is able to function properly and I now have internet connectivity.

4

I am still having this issue. Would someone be able to provide some feedback?

5

I see quite a bit of issues with your config.

I think it's because you have the Interface RGMedia on 2 APs:

But...since your DHCP now works...you haven't actually explained YOUR problem.

6

TBH, I am not sure if the issues are related but my AP drops out every 8 hours or so. When this happens, I also see this error. So, I strongly believe that the issues are related.

Also, every once n a while, devices have a hard time connecting to RGMedia.

7

What issues do you see with the configuration of the interfaces?

8 
config interface 'RGMedia'
        option type 'bridge'
        option proto 'static'
        option ipaddr '192.168.1.1'
        option netmask '255.255.255.0'

Don't see any ifname attached.

@leeandy

Hello, thank you for your feedback. From the GUI, how would I add an ifname?

10

Choose edit on RGMedia interface, physical settings - interface

11

@leeandy

So I associated the interface and then it killed my whole network

12

Can you explain what do you want to do?
Do you want to have LAN and RGMedia bridged or separated?
You have enabled the bridge on both, but you are using different IP addresses and both run dhcp server.

13

What interface you attached ?
See your wireless config above, have 3 radio, RGMedia is assign on radio1 (wlan1 ?). You need attach RGMedia to wlan1.

14

Please confirm this is not a cross post of your Master AP issue here:

You have already been told and shown multiple threads - that your master AP will drop if the client association drops. You were also offered the Travelmate package as a possible solution to your issue.

@lleachii

Yes, TravelMate was a possible solution. Which I installed and setup and I was still getting the same result
