Ugrade 3com router 3CRWDR200A-75


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:
http://3crwdr.googlepages.com/

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

3com 3crwdr200a reboots every 30 minutes


The 3com website is remarkably shoddy on this issue, and doesn't have the newest required updates. Even the KB on their site is thin on solutions.

You really need firmware 3.6.4, yet 3.0.1 is the latest on the official website. Try this page:
http://3crwdr.googlepages.com/

for the very latest firmwares, and note that it's best to clear out the router memory completely before adding the new firmware to it. This is because it sometimes doesn't like the new image files otherwise. The way I suggest:
1. Note all of your settings manually (don't save a config file, it may not read back in).
2. Hard reset and clear the memory, by holding down the reset button and powering on.
3. Connect to 192.168.1.1 with your browser - you may need to mess with the network settings on your PC to get it to connect. You will see a very bland screen, asking you for a firmware file, rather than the traditional login screen.
4. Upload the latest firmware, downloaded from the site above.
5. Allow the router to do it's business and restart.
6. Connect back to 192.168.1.1, and you will once again see the correct router software, with a new install wizard.
7. Re-enter all your settings, as noted above.

Router stops responding with red alert light turned on


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)

my 3com officeconnect doesn't work after upgrding the firmware


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
