After I tried all new internet stick, mega modem and pocket wifi. I don't see any of them got improvement but my very old USB modem work really well with the old software that come with it. (I could not find the disk now) At the moment I am using the old USB modem with the new software called Vodafone Mobile Broadband Lite. I still not happy with this software so I am looking for the old version of the software that I used to use with my USB modem. I could not find it on vodafone website. Can anyone help ?? Thank you.
