Very slow speeds with verizon dsl

[zenz]

I use to get around 100-125kbs download speeds with verizon and now im lucky enough to get even 15kbs. Heres my results with TCP analyzer if someone can lend me a hand. I'm useing a modem and router , which are both seperate.

Did what you suggested, and it seems my DL speed still remains slow.

Heres a tracing route if it helps.

Turn the power of your router off and connect your comp directly to your modem and do some speedtest. This is to check if your router is the cause for your slow speed.

unpluged and disconnected my router and connect my modem directly into my comp. Heres a speed test result

It seems it had no little differance when I connected through the modem.

Possible presence of spyware/malware. Download and update Spybot and Lavasoft Ad-Aware (you can Google search for them). Go into Windows 'Safe Mode' and scan and remove spyware.

Excessive packet loss and slightly high round trip time of 183ms. Normal values is 90-130ms. Ensure your modem is not placed near to other electrical device such as router, speakers, sub-woofer, cordless phone, power supply box, etc. It should be relocated a few feet away.
