I've been running a home network based around a Linksys router for years. We had a couple of PCs and a QNAP NAS wired to the hub and then numerous wifi-connected clients.
We've recently swapped the Linksys for a BT Home Hub. Now, client machines can only connect to the NAS via wifi; wired connections do not work. This is true for all machines and I have test wired and wireless on all those capable.
Any help / suggestions much appreciated.
