No routers, just direct cable modem to pc.
Also, does it matter if the ISPs are different?
i move this computer between two states every week/weekend. The download bandwidths of both are 5mb but the upload speeds vary

Seems like my internet browsing has been soo sluggish.

Yes, it does matter if you connect to a different ISP as your MTU value may be different in another connection.

Just run another TCP Analyzer on the new connection and use the settings below, adjusting only the MTU value and TCP Window value as shown by the TCP Analyzer report.

Use the following with TCP Optimizer:

General Settings tab:
Custom settings - check
Modify All Network Adapters - check
network adapter selection - your NIC
MTU 1500
TTL - 64
TCP Receive Window - 128480
MTU Discovery - Yes
Black Hole Detect - No
Selective Acks - Yes
Max Duplicate ACKs - 2
TCP 1323 Options:
Windows Scaling - checked
Timestamps - uncheck

Advanced Settings tab:
Max Connections per Server - 10
Max Connections per 1.0 Server - 20
LocalPriority - 1
Host Priority - 1
DNSPriority - 1
NetbtPriority - 1
Lan Browsing speedup - optimized
QoS: NonBestEffortLimit - 0
ToS: DisableUserTOSSetting - 0
ToS: DefaultTOSValue - 80
MaxNegativeCacheTtl - 0
NetFailureCacheTime - 0
NegativeSOACache Time - 0
LAN Request Buffer Size - 32768
Then select "Apply Changes" and reboot to take effect
