Yet Another Thread Asking For Help

[doomsweek]

Hello, I need help in tweaking my DSL connection. I'm from the Philippines and have a 387kbs plan from Globlines. The modem they provided me is a H9200 from Prolink and seems like I have the up to date firmware for it.

Have you clean up your registry and scan for malware?

[doomsweek]

Yes, used CCleaner and Regcleaner.

*EDIT* Spybot S&D too.

[trogers]

Yes, used CCleaner and Regcleaner.

Scan for malware? Use AVG antispyware, SpyBot and Ad-Aware 2007.

[doomsweek]

I forgot to post that I also used Spybot today. Downloading AVG Antispyware at the moment.

[doomsweek]

Already got rid of any spy-ware that were detected by Spybot and AVG Anti spy-ware.

[trogers]

Your TCP settings are correct. Reboot comp and testing speed.

Might be because it's peak time right now here.

After resetting the modem because of some config issues, it seems that the MTU has changed. I tried to change it back to 1492, but it returns to being 1392 after the modem successfully connects to the internet. Here are the results.

The upload speed is now normal where before tweaks it was at 100 kbps.

The download is still lower than 300 kbps, probably due to an overloaded network node of your ISP.
