Helping people with computers... one answer at a time.

Connecting two different internet connections is technically possible, but not easily and not likely to accomplish what you have in mind.

Is it possible combine 2 different internet connections from 2 different ISPs?

Technically, yes, anything's possible. :-). In reality though, this is usually left to the realm of high-end routers; there's no pre-packaged solution for multiple computers that I'm aware of. A single computer can sometimes make use of multiple connections which is similar to having two network cards.

I have 2 diff copmuters. One for work and one for home. Currently I'm still using dial up at both locations. Which isp can provide highspeed internet w/out me having to pay two different bills in two locations?

yes, you can combine 2 different Internet connections even without a high end router. routers are not that complicated and are essentially a highly specialized miniaturized computer. so take your old machine slap on any Linux firewall type distro. there are several, and good tutorials can be found through Google and you tube. jam extra cards into the box as needed for you internet connections the rough formula is n+1 cards where n is you number of Internet connections e.g. If i want to combine 2 internet connections I will need 3 Ethernet cards on one box. two incoming ISP connections 1 feed to my network. Also check out the article on LAN speeds and you will see that Internet connection is your bottleneck and not the Ethernet to your LAN.
