I have a Netgear router behind an RCA modem (supplied by ISP), running XP PRO. I am supposed to have 2mb throughput but only getting 256kb max. When I unplug computer from router and plug directly into modem I get my 2mb throughput. I downloaded TCPOptimizer and changed my settings but still only get 256kb when plugged into router. I know the router will slow me down some but not an 87% loss in speed. Are routers designed for a certain speed? Is something wrong with it? Are there any other settings I can change to improve it. I can't leave my computer plugged into the modem becasue it's on a network that requires others to access internet as well. BTW, I haven't checked other computers on the network to see what their throughput is but I will as soon as this is posted.
Thanks for any assistance you can provide.

Here are the results; Interesting though, because everyone is gone and only one other computer is on.

Nope. You only posted the Summary.

Okay, let's try this one. Thanks for the tip.

Do a tracert to www.yahoo.com and post, see if you have irregular ping times in the first 3 hops.
not to jump in but I am a newb and trying to find out how to fix problems with my router/modem so would like to know what my results mean if you have the time? I see something I can do to optimize it but no idea how to perform the functions to do so.

Post a new thread with the following info:
Which country are you in?
What speed did you pay your ISP to give you?
Post a TCP Analyzer report.

I did it thru start>run but the box disappears when finished, I am not fast enough with the print screen button to get all of line 13 and when I try to insert the image here, it asks for the url. SO, I feel a little handicapped right now.
Do the tracert again and when it finishes displaying hop 5, press CTRL C to stop the tracert and post.
When I press CTRL C the screen disappears just like it does when it finishes and nothing is copied to paste.
What is the model of your RCA modem?
I pressed the pause/break button and it stopped. I pressed CTRL C and the screen disappears. I can paste it as an image but can't get the text to paste here and can't figure out how to paste an image here.
The RCA modem is a DCM425

Problem is partilly solved. My service provider suggested I back up my router settings and reset it to factory defaults. WALA i get my 2mbs speed. Now my only concern is whether or not I have sacrificed security. Is there a site I can test my security?
Free Online Scans - Lots of sites:

System security test passed and I have my speed back. This is one I won't forget. If all else fails reset the router to factory settings. Thanks so much for all your help.
