I already tried safe mode with networking so i assume it's not about viruses or my antivirus. Here's from a tcp/ip analyzer

TCP options string = 020405840103030101010402
MTU = 1452
MTU is not fully optimized for broadband. Consider increasing your MTU to 1500 for better throughput. If you are using a router, it could be limiting your MTU regardless of Registry settings.
MSS = 1412
MSS is not optimized for broadband. Consider increasing your MTU value.
Default TCP Receive Window (RWIN) = 65536
RWIN Scaling (RFC1323) = 1 bits (scale factor: 2^1=2)
Unscaled TCP Receive Window = 32768

RWIN is not fully optimized (even though it is a comparatively large number). The unscaled RWIN value is lower than it should be. Also, RWIN being close to and above 65535 does not justify the header overhead of enabling TCP 1323 Options. You might want to use one of the recommended RWIN values below.

For optimum performance, consider changing RWIN to a multiple of MSS.
Other RWIN values that might work well with your current MTU/MSS:
64952 (up to 2 Mbit lines, depending on latency. MSS * 46)
129904 (1-5 Mbit lines, depending on latency. MSS * 46 * 2)
259808 (2-14 Mbit lines, depending on latency. MSS * 46 * 2^2)
519616 (8-30 Mbit lines, depending on latency. MSS * 46 * 2^3)
1039232 (25-60 Mbit lines depending on latency. MSS * 46 * 2^4)
bandwidth * delay product (Note this is not a speed test):

Your TCP Window limits you to: 2621 kbps (328 KBytes/s) @ 200ms
Your TCP Window limits you to: 1049 kbps (131 KBytes/s) @ 500ms
MTU Discovery (RFC1191) = ON
Time to live left = 40 hops
TTL value is ok.
Timestamps (RFC1323) = OFF
Selective Acknowledgements (RFC2018) = ON
IP type of service field (RFC1349) = 00000000 (0)

I have a desktop where I am getting around 7 kbps with the same modem. Just enough for my 1mbps/500kbps connection. But when I try to use this laptop, the connection becomes like this. Down is 34 in average and up is higher.

os is windows xp.

Try TCP Optimizer. I've used it for wireless connections with XP, it has never made things worse for me, sometimes helped dramatically, and it will save original settings so that you can revert to them.
