Router Won't Broadcast Unless Reset

My router has been having major problems lately [Well, for a while now]. Before, it would make all my machines [1 PC, 2 Laptops] disconnect from the internet briefly and reconnect. This doesn't impact browsing, video watching, etc. It wouldn't even say I was disconnected. However, I know it was disconnecting because programs like AIM, MSN, and multiple video games would say I lost connection. For example, MSN would disconnect and take me out of any conversations and reconnect a second later. Friends tell me that I keep going offline and then online.

I read somewhere I should change my channel, so I did and still got the same problem. Furthermore, my router/pc are literally right next to each other. Then I read elsewhere I should do a factory reset on my router by holding the reset button for a while. So I did and it reset. It started broadcasting as an unsecured network, so I was going to secure it.

1. Log in via http://192.168.0.1 (default "username: Admin and no pass")

2. Go to setup tab ----> internet ----> internet connection wizard2.1 CHANGE PASSWORD ! click next 2.2 chose time zone (you know where you are) 2.3 Configure your Internet Connection DHCP Connection (Dynamic IP Address)Choose this if your Internet connection automatically provides you with an IP Address. Most Cable Modems use this type of connection. 2.4. press "clone your computer's MAC address" ; hostname: 'your computer name in ubuntu' ( mine is "grobar" yours is ..... )

3. Go to setup tab ----> wireless settings ----> Wireless Network Setup Wizard (after this we're gonna do manual settings)

3.1 give your network a name= SSID (e.g. 'grobar')
3.2.Automatically assign a network key (Recommended) and chose WAP or WAP2
3.3 Write down the network key!!! Or do printscr and save this page.

4. Go to setup tab ----> wireless settings ---->Manual Wireless Network Setup 4.1 Wireless Network SettingsEnable Wireless : ALWAYS Wireless Network Name : (Also called the SSID) the name you gave in 3.1 802.11 Mode : chose "mixed 802.11n,g and b" Enable Auto Channel Scan : YES Wireless Channel : AUTO Transmission Rate : BEST (Mbit/s) Channel Width : AUTO 20/40 MHz Visibility Status : !!!Invisible!!! (so that no outsiders know your SSID except you) So after I finish the Internet Connection Wizard [Setting up Password etc], the http://192.168.0.1/ page asks me to click "Connect" so it can reboot the router with the settings. When I do so, the router turns off with the power icon being orange. After about 15 seconds or so, the broadcasting icon, power icon, and PC1 icon all turn green. However, there is a globe icon on it as well and that is ORANGE.

Regardless of power cycling, redoing the process, etc. it stays orange. None of my machines can connect to it. The only way I can connect again to the router is if I do a reset again (By holding the reset button). But then, I am unsecured and live in an apartment. I would like to add that the above process is the one I did previously and it worked fine. But then I had to reset the router and a similar problem occurred but I managed to fix it somehow and the first problem I talked about started happening (Reconnecting and disconnecting). Furthermore, when I go to "Connect to a Network" one of the old SSIDs I created for the router is still there regardless of the router status (Offline, Not connected, etc). I am typing this by connecting my PC directly to my modem. Router Information: D-Link DIR-615 300N
