Problem with 3Com WL-542 wireless router

I've been having this problem for a long time since I bought this on 2005. The problem is, I've already set up the internet connection, but it sometimes can be connected to the internet and sometimes it disconnected automatically then connected by itself again. I thought it was the problem with ISP at first, but after I used the other modem, I realized that it's the problem with the router, and I 've swapped a new one with 3Com at New Zealand, but the same problem still happen. Can you tell me what to do? It would be appreciated if you can also send an e-mail for me to
Thank you. Henry

    I'm having problem with 3Com Wireless Router (WL-542) accessing the internet, note that I'm able to access internet if I use TM (ISP package) supply Billion Modem my operating system is Windows XP Pro.
    TCP/IP Configuration IP address and DNS server address obtain Automatically I even try Manually configure
    getting DNS server, Primary Secondary but still unsuccesfull and has since
    switch back to Auto.
    Others Configuration using PPPoE, VPI:0, VCI:35, Encapsulation LLC, username@streamyx,

    My doubt is on Internet Settings page at ATM Interface which show both IP address and Subnet Mask:, I even use same IP & Subnet Mask add as in Billion modem, still unsuccesful.
    is both address refer to same setting as seen on Run cmd ipconfig. or which IP address is it refering to?

    Appreciate if somebody can provide help.Thank you.

If you are using DSL you will need to consult your isp about proper router configuration... meaning the modem will have to be bridged and the router configured to authenticate for you. this avoids an issue called dual NAT in the U.S. dsl providers use PPPoE for authentication i am not sure which of the available options you will use in New Zealand, and how to configure the options for it. if you are using cable or some other type of connection this will not help :/
I hope this helps if not see if you can tell me what kind of isp you have

Dont save configuration

Some routers when saving the configuration require you to stay on the page after clicking save, if you close or go to another page to quickly it stop the configuration save, stay on the same page after clicking save until the page refreshes.
Also make sure you are hardwired into the router not wireless, most newer routers do not allow access to the configuration using wireless and some allow you to see but not change the configuration wirelessly.

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

There are actually 3 models of the WL-542. Go to this page and select "All downloads" in the section matching your model. You will find the exact model number on a sticker on the side or under your WL-542.
