Help configuring my router

Hi Friend,

Please follow the steps in order to resolve the issue:

Make sure you have connected each and every wire/cables to their respective ports/places.

1. Open web browser and type the IP address of the TW100-S4W1CA in the address bar. The default IP address is At the LOGIN, click LOGIN and click on Advanced Setup.
2.Click on WAN and then click Dynamic IP on the left hand side, then select Dynamic IP (Cable Modem) and click on Apply.
3.If your ISP has registered the MAC Address of your computer that you are managing the router from click on Clone MAC Address. This will copy your computers MAC Address to the Router. If you are not managing the computer from the computer with the registered MAC Address make sure you enter the registered MAC Address manually.
4.Click on Apply.

After saving the settings you have to power cycle the modem and router(Turn off the modem and router for 15-30 seconds).

* Reconnect the modem first and wait for it to boot up.
* After the modem has booted up reconnect the Router. Open the web browser and type the IP address of the TW100-S4W1CA in the address bar. The default IP address is At the LOGIN, click LOGIN, then click on Advanced Setup.
* Go to System then Status on the left hand side of the screen
* If there is no WAN IP listed in the WAN section on the right hand side of the screen, click Renew and wait for it to come back with an IP address

I hope this will resolve the issue.

My Trendnet TW100 router disconnects after a couple of hours. I use it on a macintosh computer. It remains on while in use. Once I stop using it for any length of time, it disconnects.

Check if have the same problem if the computer is hooked directly to the Modem as well. If you find that the problem is only with the router, try upgrading the firmware. If you still have issues get back to us with the type of ISP you have (Cable/DSL)

How to connect trendnet tw100 s4w1ca to computer

Connect the Modem to the WAN port and computers to the LAN ports. Then if your ISP is Cable you have to configure if for Dynamic IP and do MAC clone. If your ISP is DSL call your ISP and know if the router has to be configured in PPPoE or Dynamic IP. Once you obtain a WAN IP address you will be able to go online.

I have reset my tw100-s4w1ca trendnet router,but still default username and password dont match

There are two kinds of resets in a router. Soft reset(reset the connection) and hard reset(reset all the settings). I think what you have performed is a soft reset. To perform a hard reset press and hold the reset button for 10 seconds. Please be aware that if you perform a hard reset you will have to re-configure your router before you connect to the internet, so make sure you have the settings handy. The default username and password is usually admin or Admin.

Let me know if you need further assistance configuring the router.

Does your wireless router have wireless capability? If it does have wifi, you must configure the wireless settings on your airport to match the wireless settings of the router

TW100-S4W1CA problem

Do you have the built in firewall turned on inside the router programming? Is the NAT firewall on? When was the last time if ever you updated the firmware on the router?
