Router/Version: Linksys MX8500
Issues/Errors: Issues, rolling back to 62966
The issue with inoperative 5GHz radio persists. Also, no IPv6 service even after restarting dhcp6c. DNSMasq seemed unstable also. I lost DNS service after about 15 minutes and had to restart dnsmaq and smartdns.

Have you tried this release after a full reset? @BrainSlayer has this router. He can certainly test it first hand if he has time. If I get time tomorrow I will dig mine out and test this release. I never put mine into service because DD-WRT just did not feel very solid on it and I do not like or really need 6ghz. Yea, I know, it falls under "640K ought to be enough for anybody" statement.
I have not updated it since last summer whenever I took on other projects but it was pretty solid then, just not solid enough to replace a good gateway router (EA8500).
All my routers have been up for months without issues, and I have many. Most are running r61711 std (06/08/25) _________________ - Linksys EA8500: I-Gateway, WAP/VAP 5ghz only. Features: VLANs, Samba, WG, Entware - r60xxx

- Linksys MX4300: (WAP/VAP (7)) Multiple VLANs over single trunk port. Entware/Samba r60xxx

could you please also check if ports 1 and 4 are getting IP and active when connected? _________________ Linksys MX8500
My XR500 says 63390 after the upgrade ...
You also made a previous post about your XR500. Is there now actually a build 63391 for the XR500, too?
Easyddup shows 63391, the same as yesterday when I did the upgrade.

No, and unless I get time this pm I don't plan to. From the reports in this thread, I don't think I am the only one with issues. Now, if BS reports that the MX8500 works properly for him, I'll plan the time to do the factory reset and manual config. I just did that in November and don't want to again unless that is the only solution. _________________ Linksys MX8500 DD-WRT v3.0-r62966 std (12/06/25)

I'm facing the same issues on my MX8500: missing 5Ghz wifi and lan ports 1-4 are not active and not getting an IP.

I was able to test. NVRAM erase, NVRAM save, and then flash with 1/17/26. Router hung and I had to power cycle it. DDWRT came up. I had to change the connection type from Disabled to Automatic. All Ethernet ports were active and were assigned IPs. No 5GHz radio. 2.4GHz radio worked normally. I changed the WiFi settings to match what my devices expected and the 2.4GHz devices connected.
I then tried to flash back to 12/06/2025 (with reset to factory) and again the router hung. Power cycling it brought back 1/17/2026 but with nvram erased. I flashed 12/06/2025 again (with reset to factory) and it hung. Power cycling brought up 12/06/2025. I then did my nvram restore and my system came back as expected. Radios working as usual. _________________ Linksys MX8500 DD-WRT v3.0-r62966 std (12/06/25)
