OS: Windows XP



I'm not a techie, so I read the above exchanges and I, too, need someone to hold my hand thru this frustrating process.
First of all, I have Windows XP(32-bit processor) and have my internet connection here in Thailand thru ADSL. No problem.
Since I live in a condo building, we have Wi-fi, which my girl friend uses free, thanks to a router I purchased.
Since she left for a month, I disconnected the LAN cable and when she returned, we couldn't get back to Wi-fi.
Apparently, the Wi-fi detected by my PC is fine, no problem. But when I reconnect the CABLES correctly, I can't get my ADSL connection to work. The signal is coming thru fine, but I can't access any Internet sites, unless I disconnect from the router and just use ADSL.
The3 router is D-Link Model DIR-300
The modem: HUAWEI Smartax MT880 Router 1E
My Internet Connection: Realtek RTL8139/810x Family Fest Ethernet NIC
Adapter: Atheros AR500 5G Wireless Network Adapter

I will try to provide any additional information you need.

First, reset the router (press and hold the reset button for 10-15 seconds untill all leds start blinking), and check if you can get a connection using a cable afterwards (wait 30 seconds before plugging in the ethernet cable). If not, unplug the power cable from your modem, plug it back in and restart your computer. Does it work now? If not, there might be an issue with your router, but I doubt there will be any issues once you've done these steps.

Next, go to Start -> Run and type 'cmd'

Next, in the command window (the black window you've just opened) type ipconfig /all

Now you will see your IP-Address and default gateway. The default gateway should be something like 192.168.0.1

Type that address in your internet browser, you should be seeing your router's login page now. If you cannot locate the username and password at the back of the router or in the manual, check the website or else try "admin" and "admin" or "admin" and "password". If nothing works, let us know so we can look it up for you.

Once you're in the router, check the wireless settings, make sure the wireless radio is enabled and set the security mode to WPA2 Personal or something. Use your mobile phone number as the passphrase or simply use any of the following:

1a2s3d4f5g

Or

1a2b3c4d5e

Or use anything you like. Save the settings, unplug the ethernet cable and try connecting using the WLAN (make a wireless connection). If it still does not work, let us know, and also if you need other support, simply reply.No success with your first suggestion. When I got to "type that address in your internet browser", I'm lost. I use Google Chrome and Firefox 3.5, but don't know how to find the place to type the address...Instead of typing "http://www.google.com" to access a website such as google, you would type the "numeric" web interface address of your HOME router using the "Default Gateway" address returned by the "ipconfig /all" command. For example: "http://192.168.0.1".I just typed : http://192.168.0.102/ in the browser and got a".....is not available....1. If you reset the router per "Hardist" instructions, the router should have the default address of "192.168.0.1". Try that address.o.k. the D-link home page opened and I couldn't find my username or password, not on the router, "admin/password" didn't work.Quote from: dahlarbear on January 25, 2010, 09:24:41 PM

Enter your Username: admin and no password (if it is default) click on OK
