Now. the better wireless router is dual-band or 3G mini wireless router. Dual-band will be a little expensive. maye need 28 USD , and the mini 3 G wireless router will also good. can support 10 devices to share the network and the price is just USD 12.5 USD.
I prefer to use the 3 G mini portable router. You can use it easily at home aslo nice in the business trip
