I suggest you call your ISP and find out the speed which you paid ISP to give you.

Uneven ping times at the modem. Clean registry with CCleaner and scan for malware.

Are you subscribing 8-10 mbps line ? If so, set TCP Receive Window - 256960.

Then Clean your Registry with Ccleaner as Trogers suggestion

That could be because i tested two different servers. Not sure. I tested the same server and your right the Pings are off(below). Im gonna conatact my ISP to find out the package for the Apartment Complex. Once i get that maybe eveyrone can offer me some advice. It would be greatly appreciated.
IF anyone has any suggestion im all ears.

What this means is that your apartment complex subscribed to RR for a line that is then shared among multiple users. Then you will not be able to get the full speed of this line as some form of bandwidth allocation would be in place to enforce equal sharing.

Try 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 - 32120
MTU Discovery - Yes
Black Hole Detect - No
Selective Acks - Yes
Max Duplicate ACKs - 2
TCP 1323 Options:
Windows Scaling - uncheck
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
