Most of the speedport routers should reconnect with this script
Use “speedport.ip” as routerip !

[[[HSRC]]]
    [[[STEP]]]
        [[[REQUEST]]]
            GET /cgi-bin/disconnect.exe HTTP/1.1
            Host: %%%routerip%%%
        [[[/REQUEST]]]
    [[[/STEP]]]
    [[[STEP]]]
        [[[REQUEST]]]
            GET /cgi-bin/connect.exe HTTP/1.1
            Host: %%%routerip%%%
        [[[/REQUEST]]]
    [[[/STEP]]]
    
[[[/HSRC]]]

if this does not work, use this one:

[[[HSRC]]]
    [[[STEP]]]
        [[[REQUEST https="true"]]]
            GET /cgi-bin/disconnect.exe HTTP/1.1
            Host: %%%routerip%%%
        [[[/REQUEST]]]
    [[[/STEP]]]
    [[[STEP]]]
        [[[REQUEST https="true"]]]
            GET /cgi-bin/connect.exe HTTP/1.1
            Host: %%%routerip%%%
        [[[/REQUEST]]]
    [[[/STEP]]]
    
[[[/HSRC]]]
