Hello all, I have a fibre modem and 2 wifi routers and need to get them chained together and cooperating. Network Equipment: a) ISP's fibre modem (4 port) b) iptime N2E wifi router (4 port) c) iptime A2400NS wifi router (4 port) Building Details: d) FTTH into cabinet in building lobby on ground floor e) RJ45 terminated cables in cabinet in building lobby on ground floor f) RJ45 terminated cables in cabinet in building lobby hardwired via cat6 into 1st floor cabinet in home hallway g) 4 lan ports in home's walls directly hardwired cat6 into cabinet in home hallway Computing devices: h) 3 desktop PCs connected via cat6 to wall mounted lan ports i) numerous mobile devices and laptops requiring wifi j) voLTE device (requires physical cat6 connection to internet) Project goals: k) all 4 in wall lan ports live l) wifi available on first floor m) all/any mobile and laptop devices can connect via wifi n) 3 desktop PCs have internet o) all devices both wired and wifi operating on same network to facilitate simple file sharing between all devices Project hurdles: p) ISP's fibre modem (4 port) pumps out four different IP addresses in separate ranges making network shares impossible q) A2400NS wifi router insists on being on a separate network range to N2E wifi router making network shares with wifi devices and one desktop PC impossible Goals achieved: k, l, m, n Goals pending: o) all devices both wired and wifi operating on same network to facilitate file sharing between all devices Current setup: [ground floor cabinet] FTTH > ISP's fibre modem > cat6 > iptime N2E wifi router > cat 6 to first floor cabinet [first floor cabinet] cat6 > 4 wall mounted lan ports [wall mounted lan ports] study 1 - desktop PC study 2 - desktop PC lounge 1 - A2400NS wifi router (item c) > cat6 to desktop PC and cat 6 to voLTE device lounge 2 - empty Current settings: N2E 192.168.0.1 - DHCP on - wifi off A2400NS 192.168.1.1 - DHCP off - wifi on Previous attempts: Somehow I managed to bodge this for a few months so it worked. A2400NS was assigned an ip of 192.168.0.99. It complained about this bitterly in the UI "ip must be in a different range" error message, but it worked anyway, as long as I set both routers to auto restart nightly. I had to move the router recently to improve wifi signal and I haven't been able to get it working again. Please help. Thanks. Edit: SOLVED I am an absolute f****** idiot. When I moved the A2400NS router (to get better wifi reception) I reconnected it and put the cable from the wall port into the ***wan*** port on the router. Previously it was in a ***lan*** port on the router. Hence why it did work before and it didn't work after due to my stupid brainfade moment. Thanks to your replies when you mentioned connecting into the lan port not the wan port it dawned on me after a few hours....oh yeah...that's right...the lan port you numpty! Brief summary of the solution. N2E router 192.168.0.1 DHCP on. Wifi off. A2400NS with lan cable from wall plugged into lan port. A2400NS manually set to 192.168.0.99 DHCP off and wifi on. (It has an option for AP mode but I didn't use it).
