Why are my router lights blinking?

My Wi-Fi seems to be wokring fine with the 3 other lapotops in my house, but for some reason my iPhone won't connect to it. The router lights are blinking and I think that has something to do with it. I have unplugged it about 5 times and they still kept blinking, I made sure all the plugs were pluggedd into the box all the way but I seem to get the same results. I'm getting upset because I have to do work on my phone and I've about given up on this. It's just a Frontier router if that helps. I need some sort of help and I don't have time to call the company and be on the phone with them for an hour and get nowhere. Please help.

Added (1). There's also no password to the router so I'm not understanding the problem. I tried resetting the router and nothing. How do you know if your router and iPhone are not compadible? If so, how can I fix this? My phone works every other day without problems and since yesterday, it hasn't been working right. When I go into my Wi-Fi settings on my phone, the name of my router is on there but when i click on it ot connect, it just keeps loading, but nothing. It now has a lock on the router when there isn't one on it and it asks for a password but there isn't one, what would I type in for the password?

Wi-Fi CONNECTION PROBLEMS IPHONE 4?

I bought this iphone 4 a few days ago the Wi-Fi does not work, by that i mean won't slide across what so ever tried airplane mode and resetting the phone constantly to no avail, also tried resetting the setting the phone was already set to factory reset when i got it, the Wi-Fi did not work before i bought it tho so i knew what i was getting i just thought i could try and get it to work. I go told i might need a new circit board or something like that but apparently its very expensive.

any useful info would be great… I never owned an iphone in my life so i'm new to it thanks.

How can my eMail be kept on my iphone after deleting from server?

I've got a Yahoo Mail account linked to my iphone. It is set up using a standard Yahoo settings.

New eMail comes in OK & can be viewed.
But when it is viewed in Outlook on a desktop (which deletes it from the server), it then also deletes from the iphone.

Does anyone know any way to stop the iphone deleting to synchronise with the server. I only want it to download new eMail & for storage rules to be independent.

This works OK for other accounts running on POP & SMTP.

I think there's a ghost in my room?

Okay so I left my old iPhone 4 in my room, fully charged and always on wife. I logged it on to my old facebook account on my iPhone 4. And I went to bed in my brothers room and slept with my brother for the night. I pulled out my phone (my new phone, Moro X) and I sent a message to my iPhone that said "respond" and when I looked on the message of the profile it said It was active about and hour ago. I logged my iPhone 4 in about 9 o'clock and its 10pm I'm getting freaked out by this. Are there really ghost? My iPhone never goes offline and it never shuts off by itself not unless I shut it off my self obviously, but its freaking me out.ever since last week I started seeing stuff on the corner of my eye and when I look in that position things are not usually there. My brother also is seeing some stuff in the house. Do you think there's a ghost in our house? And if there's, how and what can we do? I'm only 14 years old by the way.
