You're all mixed up. Here what you need to do since you won't post details and keep going on about Firefox and Internet Explorer etc...
- Plug in a CABLE. Do NOT use wireless, because its just another layer of B.S. to troubleshoot.
- If you have DSL, make sure you know your username and password. (usually the email address given to you by your ISP and some random password)
- Hard reset the router. This resets EVERYTHING on the router. So you will need to reconfigure it afterwards, but it will be accessible again.
- Here's how to do a hard reset on the Belkin Wireless G (If I remember correctly). Leave it plugged in, look at the back of the router. There's a 'reset' button, you'll need a paper clip to press it because it is a tiny hole next to the power jack. Push it down for about 10 seconds and let go. The router should reset (lights go off and come back on). If this doesn't happen, you may have to press the reset button first, plug the router in while holding it down and wait about 5 seconds.
- Next, login to your router. 192.168.2.1 in ANY browser and you don't need the http:// or :80 either.
- The default password is either (blank) or 'password'. There is no user name on your Belkin, if I remember correctly. But you can try 'admin' and 'password' for the password or just 'admin' for the login if the other two suggestions didn't work.
- Now you can reconfigure your router. If you use DSL, you will probably need to set your PPPOE login information (that user name and password I mentioned earlier). Cable is generally automatic (DHCP). You'll need to setup your wireless connection again with the appropriate SSID name and encryption and you may need to setup the wifi connection again on your computer.
- If you still aren't able to get online, check to make sure your modem has green lights, especially for the cable/dsl LED. Restart your modem, give it about 20 seconds. Then restart your router.
WTH are you talking about??? You may have gotten some line from some ***** at the help desk, but that was NOT the issue. Brand preferences don't solve problems. I've seen this router used in many different environments with DSL, successfully. It was not how the f5d7230-4 handles 'the DNS protocol' - DNS is as old as the hills and very, very standardized.
