    Hello.

    I am having this wierd issue where my internet speed is low when I do the speedtest for example it will show 4mbps where my internet normally is above 10mbps.

    But the download speeds are fine when downloading with download manager.

    So why is it slow web speed? Like youtube videos will load slow and speedtest on the web will be slow.....

    Also today I got this IP CONFLICT message in computer, so I am not sure if that has something to do with it or not.

    Can someone please help on how to fix this issue?

    Thanks.

    Fix your router settings.

    ignore post #2 here, hardly useful and a waste of pixels.

    The FIRST thing to check is why you have an IP address conflict.

    How does your computer connect to your ISP? Do you have a local router, it is shared with anyone else, or does your machine connect straight to your ISPs interface box (cable modem or DSL modem)?

    What brand of modem and router do you have? Wired or wireless to your computer?

    Fixing the IP address conflict might fix everything else. But what you've described can be a symptom of slow local DNS response issues, among many others.

    Again, once the IP address conflict is fixed, and fixed FIRST, DNS is usually pretty easy to test out.

    Look up the correct local DNS settings as spec'd by your ISP and make sure that your router or computer is using them.

    If that is already set up, try switching to some other DNS servers like the ones that Google and OpenDNS make available.

    But always keep at least ONE of your local ISP DNS servers in the search mix.

    But lets work on the IP address conflict first.

    Hey, thanks for response.

    I have Buffalo WHR-HP-G300N router.

    I have cable modem connected to the router and the router provides wired and wireless connections to other computers so its shared.

    The IP address confict message just comes up on its own and then it goes away for awhile, and the internet works fine, so I guess it gets fixed by its own, but I would like to fix it so it does not happen in future.

    What changes do I need to make to the router to fix it permanently?

    Also I am not sure how to look up DNS settings, or how to switch them to something else......

    Thanks.

    Is your wireless secure? WPA2 + AES

    Next time you get the conflict login to the router and look at the dhcp log. But my guess is someone connect wirelessly using a static IP.

    Change the def IP range to something other than 192.168.1.1/24, like 192.168.123.1/24. Also change the def SSID if you did not on the initial setup.

    Yes wireless is secure with wpa2 and aes and also the ssid are changed aswell.

    How do I go on to see if there are some dns problems?

    Normally when you get an IP conflict it caused by someone connecting using static settings. Now I wonder if by chance you connected to your router via 11n and 11g? Take a look through the dhcp log and see it something show up.

    Blue is basically right on the money with his assessment. When IP address conflicts come up most of the time it's because something else has a static IP that's in the DHCP range. Do you have anything else networked like a Printer, slingbox, Xbox360, PS3, Basically anything with a network port or Wireless card?

    Switching to Open DNS is hit or miss for me though when troubleshooting issues. I usually just use 4.2.2.2 as a DNS Server when I'm testing connectivity issues that seem to be related to DNS.
