Canon Scanner using Image Capture

Scotty,

I removed airport express from my network and re-added it.  When I tried to readd and extend existing network, it would not allow me to.  Any reason why?

Thanks,


- I have set airport extreme to create wireless network and to allow this network to be extended




- this is the error I get when I try to select the network I want to extend using the airport express.


Yes, most likely the reason that it’s not allowing you to extend the network is because the radio channel selection is set to manual. The older expresses would not be able to to extend the 5ghz range signal. I would try selecting only the 2.4ghz range. The difference between the two is basically as follows: 5ghz allows for a larger amount of data (larger bandwidth) to pass through the network but with a shorter range. The 2.4ghz allows for a smaller amount of bandwidth with a greater range. Don’t worry though. The 2.4 pipe is still way larger than all Charlotte’s current ISP download speeds. It really only effects data between computers over your local network. Stick with 2.4ghz. Disable 5ghz. (Just a thought) You may also consider setting the channel from manual to automatic. With 2.4 the range is 1 through 11. Your router will jump between the choices depending on traffic in your local area.

For some reason, we can not print to our HP printer.  Let me know your thoughts.


- when I try to open the printer utility, I get the following error.



- when I try to print something, I get the following...looking for printer.


It may be that all the changing to the network have deleted the pathway to the printer. First step in troubleshooting this issue is to delete the printer and re add it. system prefs/print and fax...hit the minus button then plus again. The printer should show on the network. Of course we also need to consider whether the printer is USB directly into one of your airport devices or if it’s wirelessly joined to the network. Either way, it should show as a bonjour printer in the add printer window. If it doesn’t then that tells us it’s fallen off line. If you’ve recently updated to Snow Leopard 10.6 then you’ll need the latest driver. 10.6 handles printers completely different that previous methods.

I know that’s not a lot to go on but it’s hard to troubleshoot networking issues over email. As far as the printer goes, it’s probably something very simple we’re overlooking.
