If you can get on motel 6 but not your own wifi router the problem does not appear to be firewall related.
If you can access your wifi router with the phone then its not the router.
That leaves only one thing: your wifi card.
That doesn't make sense. We established the wifi card works because it connects to the motel wifi.
Also the router could be restricting the network access specifically for that computer, we haven't ruled that out either. We don't know if it is the router at this stage, that is a later step if we can't establish a local problem.
Don't over think what you see for the amount of characters in the wifi password. The dots can be more or less characters and the amount of them doesn't mean anything but are there as a standard so if someone was looking over your shoulder they wouldn't know the amount of characters since that would give them a clue in hacking your connection.
Totally. If you are getting limited local access you have the right router password and you wifi card is working.
The next step is to check that you are obtaining your IP and DNS automatically.
Follow this how to with pictures except choose your wireless adapter, not the ethernet adapter like in the tutorial.
Was it set to a static address and/or DNS? And you changed it to "obtain automatically"?
