Hi, I've recently started messing with some of my old Belkin F7D8301 routers and in the process of working out the VLANs discovered there's Belkin specific firmware located in the RT-N builds. I've had tomato installed for a long time and never known about these builds. It seems these were created by Teaman, but aside from that I'm not clear what's the best builds for these routers. I have run: Toastman: tomato-K26USB-1.28.xxxx.2MIPSR2Toastman-RT-VLAN-VPN and Shibby: tomato-K26USB-1.28.RT-MIPSR2-13x-VPN without issues, but as you can see both are RT and not RT-N builds... it seems everyone who has these routers always suggests the RT and not RT-N builds. Does anyone know what's different about the RT-N builds? It seems the Belkin routers are of a similar enough design to the RT-N routers that the can be grouped together. Looking at the code, conditionals for RTN, Belkin, and a few other builds are wrapped in a CONFIG_BCMWL5 conditional. I looked for common/compatible WL part but I don't see any common parts /features between the products in this list (truth be know, I didn't look any deeper than BCM part numbers). Is this a family of routers with adapters that which use a single BCMWL5 driver? So back to the original purpose for looking at the code, I'd like to revert the firmware back to single WAN mode so there's no wasted NVRAM on a second WAN I'll never use. I've tried three different freshtomato builds and the free NVRAM ranges anywhere from less than 10 free bytes to several K. Obviously I'd like several K but I think that was a mini build. What's really doesn't make sense is in the GUI for Number of WAN Ports, there's only one selectable choice,1. The item for 2 is dimmed out, yet there are 46 entries for (840bytes) in the NVRAM for WAN2 settings. Is there a document which describes all the build flags?
