for my home router my problem ended up being a security issue

And sorry to say ssid isnt internet provider ssid = routers Name it brodcast's

But 95% chance it's the encoding
And another 4.9% your router is new and set on the highest setting
Was problem with mine my came set on default 802.11n Only (Dlink Dir-615)
second an ill give my settings


Enable Wireless : Enabled
Wireless Network Name : (Also called the SSID)
802.11 Mode : Mixed 802.11n,Mixed 802.11g and Mixed 802.11b
Enable Auto Channel Scan : Enabled
Wireless Channel : 2.4Ghz ch6
Channel Width : 20mhz
Visibility Status: Visible
Security Mode : None

Pretty much default setting's If you have to have security enabled (being paranoid) switch to wpa

Hope this helps
