To answer OP's question, you may need a router that supports load-balancing,
Windows will not be able to achieve load-balancing by itself.

the bottle neck is the WAN link in his situation, tho he can do very limited
outgoing load balancing by setup 2 static routes with the same metric, the
outbound traffic goes out through the same WAN link.
I assumed the op has only one high speed internet, but with a wireless
router.

No need to be per-packet load balancing and it is undesirable. Depends how
the router does the hash, per flow load-balancing would achieve higher
throughput if multitasking -- which is very common.
OP just needs a small router which has three interfaces, one to PC, the
other two will get (DHCP) IP addresses from two ISPs, then configure two
static routes on the router with nexthop pointing to ISP's gateway.

OP explicitily said that he/she has two Internet connections, one wireless
and one wireline. Why not?! I can get two if I need to.
Anyway, I don't think this is how ISP allocate IP addresses, since traffic will be carried over PPPoE, what address mask OP get does not really matter, the 7 (or 5) IPs OP get will not be effectively in a Ethernet LAN environment, traffic between those IPs will be bridged/routes to ISP IP gateway. Make sense?

heihei, do you believe the op doesn't know what he was talking about? if
that statement is from a professional network engineer, I read it as it

router is a consumer level wireless router, say linksys, that laptop can

Consider the following situation. A person has his/her own home internet
connection (wired), and can also get access to a wireless router in a
neighboring apartment. He/she would like to take the adavantage of the
additional wireless connection, but WindowsXP routes all the traffic via the
wired interface only.
Believe it or not, I was asked the question mentioned above by a friend who
does not have much knowledge about networking.

the reason for the windows machine to pick up the wired interface as the
default is that the wireless route metric is higher than the wiredroute. do
a "route print" on the windows machine, you can see that you have 2 default
gateways, one is the wired with metric of 1, and the another is the wireless
with metric of 5. you can change the wireless metric to 1, then you will
have 2 ECMP routes.
I am not sure how windows OS handles ECMP routes, do me a favor, capture the
packets and post the results

If doable, per-destination load balancing is the only way to go. Because
most download are TCP-based. Multiple routes per TCP connection will cause
out-of-order delivery. TCP by nature will treat any out-of-order packet as a
result of congestion, thus triggering slow-start procedure, which will
impact the throughput severely.

Agree, but it is not the performance issue. It won't work at all if
it's not per-destination based, the different source IP from different
ISP will break the TCP session immediately. Also the SOHO stateful
firewall will block it too.

其实这个不难。我假设你有broadband和evdo同时接入你的电脑。你的电脑会有两个
default gateway。windows可以更具每个defaultgateway的metric value决定最佳路线。
通常而言，sprint evdo用的是32-bit的host route，没有default gateway，所以它的
metric是direct connect，而broadband connection的default gateway是1 hop away
，所以metric 比较高。window 会default使用evdo connection。如果要load balance
，你必须要将两个default gateway的metric 设置为同样的value。
