• During the troubleshooting process, you must start from a “known” state.
Once the firmware is erased, new firmware must be loaded, and the SonicWALL must be

The Test LED flashes for approximately 90 seconds while the firmware is erased. After
completing the diagnostic sequence, the Test LED stays lit, indicating that the firmware has
been erased. It is normal for the Test LED to stay lit after erasing the firmware. It does not go
off until the firmware is installed and loaded into memory by the automatic restart.

To get the firmware, the latest is, goto www.mysonicwall.com and login with the ID this firewall is registered as.

If you have never registered before, create an user id and register the Serial. You will then be able download the firmware. On these units, you can download firmware for free with no support


I have to enter valid GMS License information to be able to download the latest GMS software to get the firmware from www.mysonicwall.com and firmware.sonicwall.com is not a valid address.

After I findout how to get the firmware I should be OK.
You do not need the GMS software. Select the drop down box and the pro 300 should be available
And you don't have the original CD's I take it either?


I do not have the CDs. I also will not be able to register the product until I get on site. I am a little concerned that I may have some conflict assuming it was prob. registered with the other admin. If anyone has a direct link or specific location for the firmware I think this would assure that I have no problems once I get on site.
You need to contact a SonicWall reseller :) and they can probably assist you very quickly. I have a copy of the firmware but cannot post it or a link here.
I can email the firmware to you. only 2mb


jli168 you can email the firmware to "blang @ brianlang.org"

It's send to you. Let me know if you didn't get it.

Does someone still have the firmware for this router, the Sonicwall Pro 300?
