I bought a USR 5461 device to pair with an existing WRT54GL to begin my testing with HSMM-MESH. I looked on the software download page, saw the USR 5461 model, and off to ebay I went to procure one. I didn't do enough research on the model after seeing it on the software download page, and it seems to me this device, and all versions of USR 5461 have only 2MB flash, and cannot run HSMM-MESH. Below are my findings, and what I have done, attempting to get the firmware loaded.

1. Used USR web interface to upload the 2.8mb firmware image, router reaches approx 70%, firmware upgrade fails.

2. Downloaded DD-WRT Micro_Generic, snatched first 28 bytes of USR firmware file, dropped it into the beginning of the DD-WRT generic bin file. Uploaded via USR web interface. Router now running DD-WRT. Checked flash size in DD-WRT (to see if maybe router has a 4mb flash, but is artificially limited by USR firmware), shows 2mb, of course, HSMM-MESH firmware upload fails.

3. Opened up router to inspect flash chip, it is an MX brand 29lv160cbtc-70g 2mb flash. The SOC has no embedded flash, and there are no other flash chips in it, so this router has 2mb flash. The firmware image for HSMM-MESH is 2.8mb. 

After extensive research last night and today, I have determined that USR never made a 5461 model router (5461/5461A) with 4mb flash, so this router has never been, nor will it ever be capable of running HSMM-MESH. 

Am I missing something stupid or obvious, or do we actually have a build for a device that can never run it? Has anyone else tried this router with HSMM-MESH? I can't be the first!

I'm not meaning to make this thread rise from the dead…Zombie Thread!…but I literally just went through the same thing today. My only guess is that you could try uploading a micro firmware that supports a thumb drive in the USB port…don't know how that would work out through the flash though.

I wish I had found this thread before I purchased my USR 5461 router. I am having the same problem with trying to install the firmware.


 It seems quite strange that this device would be listed as compatible and have a firmware file available for download if the USR 5461 doesn't have enough room for the file.


I like the idea of installing some firmware that would enable the USB port to utilize a thumb drive to expand the memory capacity to allow the installation of the Broadband-Hamnet firmware file. Has anyone attempted this yet?


Does anyone think it could be possible to create or modify the firmware file to slim it down to under 2mb so it can be installed onto the internal flash of the USR 5461?


Any other ideas, suggestions, or web links relating to this issue would be much appreciated.
