Brother MFC-7840W cannot see my Wireless Router

I have a Brother MFC-7840W and a NetGear WNHDE111.  The Brother printer is currently configured to print via the wired network.  I've attempted numerous times to set it up for wireless printing, but the printer does not find my NetGear WNHDE111 Access Point.  Any ideas why this would be, as the access point is configured to broadcast the SSID SHOWROOM.

Verify the signal strength at the printer, If you have a laptop with wireless network card (most have) place the laptop beside or just above printer and check the signal strenght. See laptop can connect  to router.

you can use tools like  Network stumbler to check the signal strength, channel, type of ip address, and type of security.

I had to set that same model up a little while ago and it was difficult.  There is a web interface you can use rather then the LCD on the front panel.

I'd make sure you are within range of access point to start.  I normally hardwire the printer to the network, use the web gui to verify and setup the settings.  Is there any encryption enabled on the WiFi?  I'd disable it for starters and see if you can get it connected.  Someimes devices don't like WEP or WPA or WPA2.

Thanks!  I'm sure the signal strength is fine as I have tested that with a laptop already.  I have not checked connectivity with the laptop though, because I have to change settings to do that.  I'll work on this next week when I get back to work.  Meanwhile, please feel free to keep the suggestions coming!!!

Have you tried to connect the printer to the wireless network from the Network menu on the printer?

Sorry for the abandoned question.  I had other things to attend to and now I'm back working on this.  I believe I've found the issue; but I'd like someone to confirm it.

My Brother MFC-7840W wireless network printer says it has an 802.11b/g wireless network interface.  My Netgear WNHDE111 Access Point says it uses 802.11n and 802.11a modes.  Would this mean the devices are not compatible because the wireless bands do not match?

Thanks!

Here is a link regarding this:

It says they are backwards compatible, but have to be in a certain mode.

I've not worked with N standard wifi stuff.  If it works like the B/G, you may want to see what encrypion is being used.  TKIP or AES.  The printer may not like the one it is set too.  Wifi gets tricky...  Great when it works, pain when it doesn't ;-)  Good luck.

As there seems to be no resolution to this that is, the wireless bands on these devices are simply not compatible; I agree that this question should be closed as unresolved.  Thanks for all the input!!!
