J4680 cannot connect to wireless

[Illinigirl01]

I'm about ready to throw either my printer or my router out the window so hopefully someone can help me. I have a j4680 that I only connect wirelessly to my Mac laptop and is unfortunately out of warranty. I had no problems when I had AT&T U-verse and used a 2wire router. I just moved and must use Comcast internet and I bought a Belkin router that is connected to the modem in my roommate's room. We use WPA security. When I try to set up the wireless both through the printer and the setup on my computer, my network is detected with a very strong signal. However when trying to connect through the front of the printer, I put in the password (and yes I put it in correctly), I get an error message saying it cannot connect. I even moved the printer right next to the router and it still wouldn't connect. When I try to connect through the setup on the computer, my network is listed, I click on it and get an error message saying that the network cannot reach the device. I don't even get a chance to enter in the password. I don't understand how 1) until 2 weeks ago my printer connected just fine;  2) my laptop, my roommate's laptop, and my iPhone can connect to the wifi; and 3) if the printer can detect the network why can't it connect to it? Please, please, please someone help me.

Well, tell me about the router settings. Is 802.11g mode available (along with other modes is OK)? What type of encryption (WEP, WPA, etc)? If WEP, change to WPA or WPA2 with a strong 13+ character password.

Thank you for your quick response. 802.11b and 802.11g are selected. WPA/ WPA2 is selected for the security mode.

OK, good.  

What Belkin model number is this?

Here are a few more tricks:

- Change the g/b channel to 11.

- Make sure MAC filtering is disabled.

- Make sure you are broadcasting your network name (SSID).

- Make sure your router has the latest firmware and is freshly restarted (by momentarily pulling the power plug).
