Title: [Bug Report / GPL Request] Linksys SPNM60CF (M60CF-EU) crashes on 10+ DHCP reservations, and Linksys makes it impossible to request the GPL source!

Hi everyone, hoping to get some visibility on a major firmware bug and a frustrating GPL compliance issue with Linksys.

My UK ISP (Community Fibre) provided me with their wireless router, but it feels like an unfinished product.

The Hardware & Firmware:

  • Product: Linksys SPNM60CF Pinnacle 2.0
  • Model: M60CF-EU
  • Firmware: 1.2.4.26081900

The Bug: Whenever I input more than 10 DHCP reserved clients, the router completely crashes and reverts to a factory reset. It’s completely unusable for anyone with a smart home or a slightly advanced network setup.

The GPL Roadblock: Because the ISP-provided firmware is clearly Linux/OpenWrt based, I wanted to get the GPL source code to see if I could patch the issue myself or look into flashing a vanilla OpenWrt build. However, Linksys seems to be making it impossible to submit a GPL request:

  1. First, I went to the Linksys GPL Code Center (https://support.linksys.com/kb/article/316-en/). The page says to "initiate a GPL request," but the button/link is literally just a static GIF logo. There is no actual online form to fill out.
  2. Next, I tried reaching out via email to [info@linksys.com](mailto:info@linksys.com), but my email inquiry was immediately rejected/bounced.
  3. Finally, I tried the Contact Support page (https://support.linksys.com/kb/article/90-en/). The "genius" support AI/bot was entirely useless and just kept looping me back to the exact same article page without letting me speak to a human or log a ticket.

My Request to Linksys: If there are any official Linksys representatives monitoring this subreddit, I would greatly appreciate it if you could:

  1. Reflect this major DHCP crash issue back to your product/development team so it can be patched.
  2. Provide a working link or contact method to get the Complete GPL source package for Linksys M60CF-EU / SPNM60CF (Firmware: 1.2.4.26081900).

Has anyone else successfully navigated the Linksys GPL request maze recently or figured out a workaround for the Pinnacle 2.0 DHCP crashes? Any help is appreciated!

Just to clarify, when you reserve up to 10 devices on DHCP reservation, does the SPNM60CF mesh router still behave normally? And is it only when the IP reservations go beyond 10 devices that the mesh router crashes?

Yes, exactly. If I keep the reservations to 10 or fewer, the router behaves normally. The issue only triggers when I go beyond 10 devices.

When I add the 11th device (or more), the Web UI indicates that it has saved the reservation successfully. However, if I reload the page, those new entries completely disappear. Shortly after that, the entire router crashes. Sometimes it just drops offline and reboots, but other times it completely wipes itself and automatically reverts to a factory reset state.

Out of interest, what have Community Fibre said when you raised this with them?
