    I have a new 2.4 20" alu iMac. Since it came with Tiger I used that for a few weeks while I adjusted to Apple after many years of PC ignorance:) Any way after upgrading to Leopard I have had quite a slowdown in internet speed. I have Comcast cable with a linksys 150 WRT N router. With Tiger I was running with very acceptable speed, but now it has really started to bog down. I have reset both my modem as well as router and no real permanent change. I realize that this issue has been touched on but I just wondered if anyone else is experiencing this.

    Thanks for any input

    I, too, am having issues with speed. When I visit a website it pauses for 6-10 seconds before loading the site. I have tried different browsers, bypassing my linksys router, restarting... NO luck. I am wondering if it is a leopard issue. I need help. These delays are torture.

    Have either of you tried with a Windows PC just to verify that it is indeed dependent on the computer and not your provider?

    I moved from Comcast a couple years ago due to speed/reliability issues (and a lack of Sunday Ticket on cable). The speed did not depend on the computer or connection (wired vs wireless) and was almost unusable from the hours of 6-10 p.m.

    Check your DNS server in network settings.

    Sometimes it helps to allow your router resolve this for you (leave the DNS server field blank). And sometimes it helps to have your ISP's DNS address listed in the server option.

    Anytime you have a bad address in your network settings, it forces your Mac to lookup things that don't exist, thus causing major slowdowns.

    Also check Comcast and see if there are any issues that exist with Leopard.

    I am with Charter (internet only) and had no luck with customer-no-service today. This sucks.

    Speaking of DNS, check out openDNS, it doubled my internet speed. :D
