I just received a cisco Aironet 350 wireless card for a j720. My question is how to go online with it.
What settings do i need to change in explorer? Where do i find the 10 hex code? Is there a guide from start to finish?
If you are new to networking with these things, suggest you read the tutorials in the support & tutorials section of this website...you'll get a lot of general info there.
You don't need a 10 code hex key for open networks, only if you are attempting to connect with a WEP encrypted network.
For your specific card, do a search here using the keywords "Aironet 350 720" and you will see this has been asked in one form or another many times...and answered.
Good luck with the learning curve...this is something that once you learn and understand it, will pretty much apply to any HPC in the future...
I found what I needed and success has been achieved.
