Problems with internet explorer?

I've got problems with my Wi-Fi connexion. When I write my login and my password : :





- It says "invalid password"


- or it says "the cannot be displayed"





I didn't touch anything when i left my room. But now, when i want to click on the link so that I can write my login





Run Time Error!





Program : C:\Program Files\Internet Explorer\iexplorer.exe





This application has requested the Runtime to terminate it in an unusual way





Please contact the application's support team for more information.








What does it mean ? What can I do ?





Thank you for helping me.

It means you need firefox instead of internet explorer. you can get it for free from the following link. I use firefox for nearly all my browsing.
Reply:Dude, ditch internet explorer. It sucks on many different levels, perhaps on this one also.
Reply:Try resetting the router.. every now and again you have to do that because of connection interference.
