    Hi All, I am looking for help in connecting two eir modems . One end of my house the wifi is very bad so i had a spare modem f2000 eir aand i thought i could connect the 2 with ethernet cable so i went out and bought 15 meters of it ( cat 5 ) lol. anyway the second modem shows up on my laptop without internet connection?. the first modem i will call modem 1 and the second one ill call modem 2 this is the one I am trying to connect for wifi at other end of house. I connected ethernet cable in lan port of modem 1 to lan port 1 of modem 2 it shows up as a connection but when i put in pass word it wont connect . any help will be greatly appreciated thanks in advance. ps I am with eir on fiber broadband 100mb at modem 1. thanks Eoin.

    Hi Eoin.

    There are two ways you can make this work, but neither is ideal. This way is easiest, but if it doesn't work come back and we'll try the second.

    Presuming Modem 1 is the one with the Internet connection you'll need to make some changes to modem 2.

    If they're set to defaults I'd expect they have different WIFI networks. That's OK - don't make it too complicated.

    You'll need to change the IP address of modem 2 as it's the same as modem 1. You do this in the Home Network LAN section of the settings.

    The default is - change it to something else with the same first three numbers, perhaps

    This will get you started, but to prevent conflicts you should also look for the DHCP server setting in the LAN section and turn it off for modem 2.
