Nothing of the methods worked for me and I still not get access to my 3Com !
All you need to do is to reset your modem. This can be done easily by clicking on the reset button at the back or at the bottom of your router. If you hold down this small button for approximately 20 seconds, (you may have to use a toothpick), then your modem will get restored to the factory settings. What you need to keep in mind is that when you reset your modem, you will lose your connection online. It is therefore better to take an expert's assistance in this regard. Note: If you have not enough information, it is obviously recommended that you should get help from a person who has all the knowledge about this topic.
