Question about 3Com OfficeConnect Wireless Router

1 Answer

I have a 3com 3CRWER100-75 router. I have seen a new firmware version - 1.3.14. Downloaded it from the 3Com site, unzipped it and started the upgrade. After 2% have been transferred, the connection stalled. After a good 15 Minutes, I tried to restart the router, but lost connection. Pressed the reset button for (more than) 5 seconds in order to get back to factory default, but no reset effect is seen on the leds afterwards. After power off and on - no connection. On its bootup, the leds play a little, and with a sniffer I can see that the router sends the 3 ARP who has messages: "Who Has 10.10.12.72". It does not respond to pings (no matter if the ping is sent to the manual designated "default" 192.168.1.1 or to 10.10.12.72). Any ideas how to get the damn thing back to a useful state?

We have a 3CRWDR101A-75 3com wifi router and its not upgrading the firmware, I downloaded the firmware from the site and then when I try to upgrade all I get is file verification failed... any thoughts...


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.

How to change software version of 3Com router from 1.20 ver to another latest version because it not support a lot of command for configuration.


Usually the software version of routers is called a firmware. You will need to download the latest frimware version from there website and upload it to your router through its configuration page.
You get to the configuration page through the routers ip address, usually its 192.168.1.1 or 192.168.0.1, you will need to type this into a web browser.

Please Help When I try to enable my Apple MacAddress at 3Com router wl-537 it informs nota a valid macaddress. What can be done?


I had the same problem with the Ipod of my son.
To solve the problem, just upgrade your Firmware to the latest version. This will allow u to define the new MAC address. But the problem is that this firmware version doesn't work well, reseting the router every couple of hours. So to solve this problem, after you upgraded the FW and defined the MAC address, downgrade the firmware to you previous version, the new mac address will still there.
This workaround you need to do every time that you want to define any new MAC address

Why does wireless router model 3CRWE754G72-A keep rebooting during internet sessions? This can happen as often as every five minutes or so. I'm running XP pro, 32 bit SP3. Firmware version is 1.24. I have...


1. check the manufacturers web site for firmware update.
2. relocate the router to another location the room away from walls or cordless phones or microwave.
Isolate from any device that broadcast a frequency.
3. You may need to update the router. the firmware may be obsolete.

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.

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
