Posted: Mon Jun 06, 2022 20:09 Post subject: [SOLVED] WLANs unable to connect to internet. DNS problem?
I have recently done a long overdue build upgrade on my main router from Kong 35550M to the latest builds. My routers and network setup are shown in my signature. This network is connected to my ISP’s router via ethernet cable with a static IP address assigned from the ISP router.
I used the Wikis Tutorials, Wireless_Access_Point and Multiple_WLANs to set up the network previously and reviewed them when this problem started.
After upgrading to the latest firmware everything worked well except I have a problem with Router 1, D-Link DIR-885L A1, the WLANs not being able to connect to the internet. It is only the main wireless interfaces that will not work, wl0 and wl1. The wired LAN connections do work. Two VAPs set up on wl0, as wl0.1 and wl0.2 work fine. Also, all the WAP’s WLANs, main, wl0 and wl1, and VAPs, work fine and connect well. I am also able to roam access the VAPs from one router to another and back.
I have read numerous articles in the Wiki and posts under Broadcom SOC Hardware and Advanced Networking and come to the conclusion that the problem is with the DNS setup. I have tried many combinations of settings without success. As egc has said DNS is very complex with many settings across many windows.
I have also tried various settings in the Setup-Networking GUI window. A copy of my current settings attached.
I am not running any VPNs.
I will forward logs if you tell me which /directory/file and how and where to remove any identifiying IPs and tags.
Thank you in advance for you help and support. _________________ ___________________________________________

just to clarify...did you do a reset and manually add all the settings ?
Coming form an old build Kong 35550M this is a must...
as well i dont see your vap and guest networks anywhere
i rather live them to default create 2 bridges and assign them to a br1 and br2 than add the DHCPd to those br1 & br2
than usually DNS is the default DNSmasq address (you can add to advanced DNSmasq rules no-resolv and server=9.9.9.9 or what ever DNS you prefer) and you don't have to add any extra DNS to those bridges you ve made...
in general i always bridge any new interfaces i create, as its more flexible...
but lets see if someone will come with another solution to your problem... _________________ Atheros

Yes I did do a manual reset and added all the settings manually.
The two VAPs are shown toward the bottom of the .png as Network Configuration wl0.1 and wl0.2 and in DHCPD, Multiple DHCP Servers at the bottom.
This configuration plus these commands added to the DNSmasq Additional Options allowed everthing to work with the Kong build.
interface=wl0.1
dhcp-option=wl0.1,3,192.168.32.1
dhcp-range=wl0.1,192.168.32.64,192.168.32.192,255.255.255.0,12h
interface=wl0.2
dhcp-option=wl0.2,3,192.168.10.1
dhcp-range=wl0.2,192.168.10.100,192.168.10.200,255.255.255.0,7h
dhcp-option=6,209.67.222.222,1.1.1.1 _________________ ___________________________________________

In your screenshot (labeled dir 855L ??) there is an entry under assign to bridge which is not present on any of my routers, granted I do not have your router so perhaps it should be there but I have my doubts.
As you also have put all those not really necessary settings under DNSmasq Additional Options I would consider doing a full reset and only start with a minimal configuration to see if the WLAN is working.
Minimal configuration:
On Setup page
Ignore WAN DNS: Enabled (ticked)
Change Local IP address if you want to
Static DNS 1: 9.9.9.9 (or anything else you trust/want)
Static DNS 2: 1.0.0.1 (or anything else you trust/want)

egc,
Thank you for your clear, concise instructions for dealing with my problem. Everything is now working.
You reminded me of the old troubleshooting adage, to start at the beginning and add one thing at a time until you find the problem. After fighting with Firefox, MacOS and iOS I finally was able to set everything thing up functionally the same as my old setup. It is a much simpler setup now.
Now on to setting up NAS and perhaps a router based VPN.
Thank you again for your professional support. _________________ ___________________________________________
