I Can't log into http://192.168.1.1/, Why?

I can't figure out how to get into this. At first I thought the website was messed or something when it typed 2 or 4 letters with one letter, or deleting 2 when I typed a number, but I was told that that was normal and to ignore it. What should I do?

First, Reset the router as follows: Find a thin wire and insert it into the reset hole which behind the router. Hold about 10 seconds, when you see the router lights off and brighten again, release the reset hole, router reset completed. In addition, you can try a different browser or reset the IE.
