    I see your question... Optimized for Internet access.. WEB SURFING... My system seems quite slow no matter what I change..

    Ok now were getting somewhere, but we still need more information. What kind of speed do you get if you connect directly to the internet without the router. And then what kind of speed do you get if you connect with the router? DD-WRT as well as any other 3rd-party firmware should work as soon as you install them as far as direct internet access. However you can start messing things up by changing settings and doing things you just dont need to do.

    Thanks for reply.. Sorry for delay.. Work has had me 7 days a week for almost a month...

    Directly connected bypassing router I get what seems like full speed according to tests.. close to 1.5MB?s Download. (DSL by the way)...

    After router.. I seem to drop to below .6MB with no one else using internet ..

    I was wondering.. Can Antivirus programs slow down your access.. I know the email scanners can drop your email download speed by 10 times...

    Maybe that is my problem..??

    At times it just drags.. Others its not so bad...

    Let me ask.. What would be good setinsg for a network that has 10 PCs half wired half wireless.. (Wired is what is slow... Wireless is always somewhat darggy..) But Wired seems to have the most change from somewhat fast to very slow...

    Thanks Jerry

    Thanks meee I will try these and see...

    I do have a significant source of RF in the house... Ham radios.. Wireless weather station, Wireless securty system, wireless cameras.. etc etc...

    I have disabled all these and restarted Internet connections.. Reset Router and power cycled the DSL modem and pcs.. So I do not think that is an issue at this point???

    I would do several things. I have a 6 computer network, 4 wired and 2 laptops, and I have a 15mbps connection (cable). I get full bore on everything so long as the computer is actually capable.

    1. With that many computers you have to increase the number of active ports to the max and make the timeout for inactive ports something like 3 minutes.

    2. The broadcom chip can be kicked up a notch from 200mhz to 216 if it's not already set like that.

    3. Put the wired computers on a smart switch and connect that switch to the linksys router. This removes a lot of the stress on the router (it's what I do) and keeps any file transfers or shares off of the router. There's a cheap Linksys gigabit router that does 200mbps sustained and keeps its own routing table it's under a hundred.

    Other Tweaks: Your ISP's DNS may be too slow, switch to someone else's DNS like OpenDNS.org Tweak the RWIN and TXWIN settings by using DSLREPORTS.COM tools to max the computers settings. I have an old P3-550 that gets 12mbps running OS/2 that has its settings corrected from DSLREPORTS tweak tools. And yes, AV/Spyware blockers can be very resource intensive and slow you down.

    The linksys can do 25-27 mbps, but you have to turn off the SPI firewall functions.

    Hi Mee.. No only the weather station PC is on the Linksys wireless network.. All other RF and wireless devices are on their own frequency ie.. 400 MHZ for cameras and wireless weather station transmitters etc....

    Justt a lot of RF flying around that is not on or near the 2.4 GHz wireless network..

    Got it...

    Hi Slove,

    I implemented each of your sugestions in order..

    Item 1 Made a bit of difference...

    2) I speed up the CPU to 250Mhz May have made a difference..

    3) I made these changes as well. Was easy.. Once I figured out what a Smart Switch.. Made a big difference... Thanks for info...

    The last item.. OpenDNS.org made the biggest difference for internet access... I was to point where my ISP's DNS was not only slow.. It was timing out on sites I knew were still up.. I implements the OPEN.DNS changes.. And WOW.. What speed.. I could into the other sites and talk about fast.. I did not tell the Wife and Kids.. They each ahve their own machine on the system wirlessly... With in a few hours they were coming in asking.. "Did you do something to the internet"? I said why.. They said.. Its working really fast now..

    Thanks a Bunch... Sorry for delay in getting back to you.. I have been working a lot up until now..
