I have a Home Hub 5 type A and broadband extender flex 1000. For the last year this has worked fine with one ethernet connection running through the extender. I now want to run two through. When I add the second connection through ethernet 2 on the extender, the router crashes and both the ethernet and wifi connections go down. I have to unplug the ethernet 2 connection on the extender and restart the router before it will work again. Any help gratefully accepted!
