[ubuntu] Advice Requested - Adding Wireless to a wired network

Hello Everyone,

I could use some advice - I have DSL coming in to a wired network - typical 5 port router. I would like to add wireless capability, but it is not something that would be in use at all times. Mainly just for use with smart-phone, and perhaps a laptop in the future. Switching to wireless for everything is not an option. I would just like to add the capability for use now and again.

I have read a little about portable wireless for travellers, but I'm really not sure if that is the best option.

Please let me know if you have a similar set-up, and offer suggestions as you see fit.

Thanks in advance!
