    My internet up until last week was working fine, our modem is downstairs in my brothers room and he's connected via ethernet cable and I'm connected via Wifi upstairs on my pc. I know a wired connection will always have better speeds but up until last week I was getting 16mb and even sometimes 20, now I'm barely getting 3 if I'm lucky. It was working fine today and I was getting 13 mb all day and as soon as he turned on his pc it dropped to 3mb and I did a speedtest on his pc and he was getting 14mb where as I was only getting 1mb.

    Any ideas what could be wrong?

    Thanks

    Most likely he's inadvertently nuking your connection.

    Check for P2P software, W10 updater(if hes on 7 or 8), Games patches (LOL, WOW, WoT etc).

    If his LAN connection connection is 100Mb then more than 10% traffic means heavy downloading and if his connection is 1Gb then more than 1% traffic is the same. You're probably on ADSL so excessive uploads wont really show on these graphs but will screw with your throughput.

    As soon as I turned it off it went back up to 13 and as soon as I turned his pc back on, it hadnt even booted to windows and it dropped back to 2 again.

    If its that quick then we're talking hardware.

    Try disconnecting his ethernet cable and powering on: If you slow down still its RFI. If not the his NIC is related though how I'm not sure.

    What RFI ?How do I fix it? I plugged out his ethernet and mine was still slow, also I tried a different laptop and plugged it in and it was getting great speed.

    I just moved the modem and all of a sudden I'm getting 13mb again.

    RFI = Radio Frequency Interference.

    Coils in his power supply could in theory emit noise at 2.4Ghz and boom your signal is degraded. Very unlucky for it be just in that 20Mhz or so you're using but not impossible. Normally microwave ovens are the biggest culprit.

    Ya I placed the modem onto the table where his pc was last week because he kept knocking it off, now its back on the table where his monitors are.

    Thanks for your help ED.
