Your MTU of 1392 is off the normal values.

Try the following with TCP Optimizer just to first adjust your MTU:

General Settings tab:
Custom settings - check
Modify All Network Adapters - check
network adapter selection - your NIC
MTU 1500
TTL - 64
TCP Receive Window - leave blank
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 - 8
Max Connections per 1.0 Server - 8
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

After reboot, post a new TCP Analyzer report.

Log into your ProLink and set MTU or MRU to 1500 and MSS to 1460. Save and reboot the ProLink. Then post another TCP Analyzer report.

[xhitfield]

i cant seem to find MSS in my manual. but MTU is set to 1500 (default).

Check with your peers at this link to see if your Prolink has the latest firmware:

http://www.pinoydsl.net/viewforum.php?f=6

Your MTU should be either 1500, 1492 or 1480 before you can tweak your comp to optimum.

i already have the latest firmware version of prolink h9200. (v. 2.5.060823m) but still, my TCP analyzer repot says my MTU is not fully optimized for broadband.

Have you installed some other tweak software besides TCP Optimizer?

Test speed at this link using the test server in Quezon City and post your results:

Scan and remove possible spyware/malware.

Search Google for

SpyBot
Ad-Aware 2007
a-Squared Free

And cleanup your registry with CCleaner.

[xhitfield]

scanning really took time.. but WOW! this the first time it happened. i never reached a speed like this before.. do i have to scan for adwares regularly to maintain such speed?

I do a deep scan once a month and smart scans weekly.

Also, look through SpyBot and use its functions to immunize your comp, set 'tea timer' to monitor registry changes, lock down hosts files, etc...
