Has this ever happened to you? You go into your favorite cafe (with free wifi of course) and order your coffee. Then, after paying for the coffee and maybe a muffin, you sit down and open up your laptop. To your total disappointment, the wifi connection doesn’t seem to have ANY internet connectivity! BLAST! What a waste of 5 bucks, right? Well, not necessarily…
At this point, you should ask yourself a few questions.
- Am I connected to the Access Point?
- Have I been assigned a private IP address?
- Can I reach the Access Point via web browser?
So, let’s assume the answer to question number 1 is YES…I am connected to the access point with a good signal! Now I need to know if I have an IP address.
In Windows, open a command prompt and type:
…In Linux or Mac, open a Terminal and type:
There are other ways to find your IP, but these work just fine. The private IP address will likely look something like 192.168.1.xxx.
Next, take that IP and change the last part (xxx) to 1. For example, if it was 192.168.1.193, change it to 192.168.1.1. This is the gateway address. Now, let’s try entering that gateway address into a web browser. If you are prompted for a username/password that’s good news! That means that the Access Point has port 80 open and is running a web server to allow web based configuration. Look for a model number or company name in the window asking for a password. If it’s something like WRT54G, that is a Linksys and the default username and password are both: admin.
If you can’t get in with a default username/password, you should probably just move on…unless you want to try something more advanced of course. :)
Once you ARE logged in though, you can do some things to get the free wifi working again. Release and renew the public IP…reboot the Access Point. That combination will fix a lot of connectivity issues!
Have Fun!
