I have an all-in-one Netgear DG834GT on the ground floor of my house, connected to my ADSL line. My desktops and server are connected to it over ethernet, laptops usually over wifi, but sometimes over ethernet for backups etc.
I want to rearrange my house and so in future want to be able to connect multiple PCs over ethernet (mostly) and wifi (sometimes) on the ground or upper floor, with the minimum of cabling work.
I don't want to go as far as putting Ethernet wall jacks in. Current wifi signal upstairs is unreliable.
I'm not really clear what hardware I need to add. Can I run a single Cat 5e cable from the DG834GT, to the upper floor and put another similar (but without modem) combined wired router/wifi point on the end? Are there any other considerations?
The 834GT is 100 Mbit and wireless-G; PCs are a mix of 100/1000 Mbit, Wireless-G and -N. It probably makes sense for any new hardware to support the higher speeds.
I think power-line based networking is out as the floors are each on a different ring.
