3CRWDR101A-75 Firmware update KILLS router! :: DSL ...

I have been running my 3com 3CRWDR101A-75 Office Connect router for about 4 months without too much trouble. Over the past few days I ...

..

Usually the upgrade routine is in the router program. Log into the router and find the option to upgrade to latest firmware.

thank you

The downloaded file is "corrupt", and thus it fails the "verification" process.

Download the firmware again, and compare the two files.

Or, use a different computer to download the firmware, and to do the firmware-update.

Same problem... anyone?

The first thing I would check would be in the configuration (point your web browser to 192.168.1.1 when you have a wired connection) panel, under:
Wireless settings > configuration

If the 'Wireless mode' is set to 'SuperG', this may be your problem. The SuperG setting will only work with SuperG enabled wireless adapters. First change this setting to 'Mixed 11b/11g'; if it still doesn't work switch down to '11g' then to '11b'.

Do all your wireless testing with a laptop or PC as close to the router as possible - same room at the very least.

If all other settings are correct (double check them), this is the only thing I can think of that can instantly make a difference.

If you feel the firmware may be faiilty, note that although 3.0.1 is the 'newest' on the 3com website, even in their own knowledge base they refer to newer versions. These newer versions are available at:

You could try using one of these (at your own risk), if you feel it is the firmware itself that is causing the fault.

i am not sure of this, however try this link this might help

Is the actual router not responding or the internet?

(IE - can you still log into the router but the internet won't work, or will it not even connect to the router)

Are you able to login to the router? If you can reset the router to factory defaults..If you can't login to the router...Is there an external reset button on the router you could try to reset. with a paperclip? Otherwise, I had this happen on a linksys router/switch. New router time. You should just return it where you purchased the product. There was already something seemingly going wrong if it was rebooting. 3 weeks? just return it. don't even mention the firmware update. Here is the site info for 3com: http://knowledgebase.3com.com/ OfficeConnect - Firmware upgrade fails with incorrect user interface image Problem: Incorrect user interface image Problem: Firmware upgrade fails Problem: Error when upgrading firmware Problem: Incorrect firmware Problem: Wrong firmware Fact: Firmware Fact: Download Fact: Update Fact: Upgrade Cause: The downloaded .exe has not been extracted Fix: The downloaded .exe needs to be extracted by double clicking on it. When performing the firmware update use the extracted files that were obtained from the "exe" file. e.g You will obtain a "bin" or "dlf" type of file which is the firmware required for your upgrade. Let me know what happens. Good Luck, Tim
