Thanks for taking a look - much obliged:thumb:.
Any tips would be appreciated.

My speed tests are running about 1324/325 Kb.

Is it even possible to improve upon this given my current plan? [1.5Mb DSL]
Please lemme know if I've left anything out (I read the sticky I swear:rolleyes:)

Naughty - over.

Thank you very much RS:thumb:.

I'll do just that, run a speed test and post the results.

Again,
thanks for taking the time:D.

Well, it was worth a shot ;).

After the suggested config and a reboot my fastest speeds (ran 5 x's to be sure) were 1310/300 - so I reset TCP Optmz to "Optimal Settings" and another reboot.

The average of my last 5 tests was 1340/325.

Could there be something else I'm missin'? I may just be at my max?
My average dl speeds with, say, Utorrent are about 140-150kb, is this acceptable for a (supposed) 1.5MB connection?

Thanks again for your patience -

Post your new TCP Analyzer, then do a tracert yahoo.com and post.

Fastest of 5 tests: 1325/323 (average 1315/321)

What'd ya think?

Not bad. Almost 90% of 1500 kbps. Torrents download would be about 140-150 KB/s. Make sure you set global upload speed limit to only 25 KB/s.

Make sure you set global upload speed limit to only 25 KB/s.
You know it baby:nod:...I actually hover around 22KB and sometimes I'll hit 160 down.

Curious thing; while my overall speeds have dropped a notch with this last config (w/ "Optimal" I was hitting 1340) my pages are loading noticeably faster - is this a by-product?

And thank you by the way:thumb:.
