That's a good point - it's a Vigor 2600 and isn't actually meant to be there. The previous router, a brand new Edimax type, was switched out with this to eliminate the router during previous fault finding, and as that problem mysteriously went away I left the Vigor in situ. Hmmm.. that sounds dodgy but actually the routers were switched several times without effect, so the original wasn't broken - just luck that the Vigor was in place when it cleared up

I'll try swapping back today.
