DSL Sync Lose

    Hi guys.
    I have 3 clients on my network,all connected to a WRV54G (used 2 b a BEFSR81) setup as a router the router in turn is connected to my ISP dslmodem.The clients recieve their IP address through DHCP on the router & the router is assigned its IP address by dslmodem.
    Now any time a phone call comes in or out it disconnects the dslsync on my dslmodem.I tried plugging one of the clients directly to the modem instead of through router and the problem stops,I tried 2 PC's connected directly to the dslmodem(1usb,1ethernet) and problem stops. So my thinking is something between dsl modem and WRV54G is conflicting and is casuing my problems.
    This is v annoying specially as when remote connection keeps on disconnecting.
    Any help or pointers would be great thank you
    BTW Firmware Version is 2.37(EU)

    EDIT : This also used to happen with my BEFSR81

    This makes me think settings are wrong on dslmodem or router?
    Please any help would be great.

    If anyone cant suggest something can they just clear a few things up for me dslmodem ----> router cable should be what crossover UTP??? and router ------> client cables what should it be?

    You should have "straight thru" CAT5 from the modem to the router' you can use "straight thru" from any of the four LAN ports to any additional wired clients.

    What is your actual service for connection, meaning are you ADSL, DSL, or PPPoE? I wouldn't have thought you'd get that type of disconnect with ADSL or DSL...

    thats the support page, as far as I know it's ADSL what Im told by my ISP (in ireland) like getting blood from a stone!
    The cables I have right all straight through

    Have you got a microfilter on all phone points on that number?

    Have you tried changing the microfilter that's where the DSL modems plugged in?

    Yep Taz engineer came out and changed the filter box to try and fix the problem but with no luck at all. Ive gone throught main adsl modem settings from default settings to advanced settings that I normal use and problem is still problematic
