14. If you type "summary" you will see all the switch details.

Amongst these details are the IP address of the switch. If you have DHCP on your network this switch is connected to it will receive one as in my case below, so I can now configure the rest via a web browser.

If not you can use the "ipsetup" command to set a static management IP and access via a web browser.

15. Once you can access the web management page for the switch make sure you set a strong password for "admin" and store it in a secure encrypted location for next time.

16. Don't forget to save your new configuration! Otherwise the switch will be at factory defaults if the power goes off!!

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.

My belkin play router works fine on my xbox, yet when I try to use my computer I get a "this webpage cannot be displayed" error, but when I reboot the play router it stops for a few hours


Hi lets we tried to Upgrade your firmware version.

Updating your Routers Firmware
The following steps will show you how to update your routers firmware using its web interface.

You do not need to be connected to the Internet as this interface is built into the router itself.

Setup Steps

Locate and download the firmware file from the Belkin support site. (Type in your part number in the search box in the top right and look for "Firmware" in the title)

Save the file to a location on your computer where you can get to it easily, such as your desktop.
Connect the computer to one of the four gray ports on the back of the router.

Open a web browser on the computer.

In the address bar of the web browser, type http://192.168.2.1 and press Enter on your keyboard.
Click Login in the upper right-hand corner of the page. The router does not ship with a password, so just click Submit.

Click on "Firmware Update" toward the bottom of the left-hand menu.
Click the Browse button toward the middle of the screen to search for the file you saved previously.

Select the firmware file by left-clicking on it and then click the Open button in the lower right corner of the window. This will take you back into the router's interface.


Click the Update button.

A prompt asking, "Are you sure you want to continue with upgrading?" will appear. Click OK.
A second prompt will open telling you the router will not respond during the upgrade and warning you not to remove the power supply to the router. Click OK once more.
Congratulations. The firmware has been updated successfully

OK. First, that dg836gt_1_02_09.img file does not seem to be a firmware file. You need to get a .zip file or a .bin file to upgrade the firmware. Check Netgear's website for the current firmware. If it is a .zip file, then you need to extract the .bin file from the .zip file with winzip software. Then, log into your router with Internet Explorer by typing it the routers IP address in the address bar like this http://xxx.xxx.xxx.xxx. Enter user name and password. Look for a tab that states software update. Browse for the .bin file you downloaded or extracted from the .zip and click update.

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
