Tomato wireless rate drop in client mode

    I recently changed from using dd-wrt on my routers to using Tomato because of stability appears to be better, i was having trouble using dd-wrt because of constant rate drops.

    But in my redesign of my home network i encountered the following problem that makes my wifi speed drop to 2Mbps and stay there until i disconnect and reconnect again.

    My current setup is the following:

    #Router 1 - Normal ADSL ADB router with SSID XXX and WPA security with no ethernet clients (only wifi)

    IP Range - 192.168.1.X
    DHCP Enabled
    Firewall Enabled
    UPNP Enabled
    QOS Disabled
    WMM Disabled

    #Router 2 - Tomato powered Linksys WRT150N firmware tomato-K26-1.28.RT-MIPSR1-116-Mini (Also tried K24 with same effect) with SSID YYY and WPA security with Router 3 attached via ethernet.

    Connected to Router 1 via Client mode
    IP Range - 192.168.2.X
    DHCP Enabled
    Firewall Enabled (actually i can't tell in tomato lol)
    UPNP Enabled
    QOS Disabled
    WMM Disabled

    Default settings apart from the client mode and change in ip range nothing else was changed.

    #Router 3 - SMC router WBR14G2

    Connected via ethernet to Router 1 to serve as Access Point
    DHCP Disabled
    Firewall Disabled
    NAT Disabled
    UPNP Disabled
    QOS Disabled

    The problem occurs when i connect via wireless to #Router 3 i start downloading a file and suddenly the download rate drops to 2-1Mbps

    If i connect via ethernet to #Router 2 i get max speed and no drops.

    I tried 3 different routers connected via ethernet to router 2 and they all generate the same problem.

    The only solution i found is that when i place the IP of #Router 2 in the DMZ (demilitarized zone) of #Router 1 and the problem doesn't occur.

    My question is, is there any extra config i need to do on Router 2 or 3 so that i don't have to place the ip in the DMZ? Also why does this happen is it a firewall problem?

    Been battling this for a week with no success. Has anyone else encountered this problem?

    Best Regards
