[FeeD_RulZ]

hello friends
i have WiMax wireless internet connection and 3G mobile internet connection.
i need to surf internet using my mobile broadband and download stuff from Wimax wireless broadband at the same time.
browsing and downloading at the same time,is just waste of time.
so how can i use these two connection at once?
any ideas?
@ Lucy Girl
for surfing 3g is the best option..
42GB for just 12$ or 1.5GB per 0.4$
im in sri lanka
in SL rupees
1500MB is only 45Rs
speed is 1.8Mbps down and 384kpbs up

two different computers
why would you do heavy surfing on 3G? does that not create a huge phone bill?

you can use two internet connections at the same time by operating one through one device and operating the other through a different device.

Device's available in a typical laptop are
ethernet
modem dial up
usb device
inbuilt wireless

its best to use two different browsers so that one browser connects through one device, the other browser through another device.

You can use if your computer has high capacity but your computer can also became carupted.
