Hope I'm understanding this correctly;
CAT3 Telephone Cable can't be used as Ethernet cable, only Telephone
cable. I've seen many Electricians quote for it as networking cable only
to find out it doesn't work.
I've heard in some cases tin CAT3 has been installed and that does crop
high frequencies which wouldn't make it suitable for ADSL.
However, the normal solution assuming your Telephone sockets are wired
with copper CAT3 (it should say on the cable sheath).
Plug an ADSL filter "box" into the normal Telephone socket, Phone and
ADSL modem into the filter (if you have multiple sockets/phones you'll
need a filter on every phone otherwise the modem will act flakey). These
are normally all supplied by your internet provider, and someone will
likely come around to install it anyway.
You can then use Ethernet CAT5 leads to plug the computers into your
modem's "LAN" ports as a kind of network switch This is preferable over
wireless if you want the best speed. Although not everyone likes
spagetti junction so otherwise just connect to the wireless.
A few things worth checking on your modem if you want to dig into it's
* Plug a laptop/computer into a "LAN" port on the modem, make sure it
picks up an IP from the modem. You can nearly always access the
configuration by typing the modem's IP address into a web browser,
normally 192.168.1.1, username/password will be in a manual or on the
* I recommend disabling uPnP, it's a security risk as it allows network
devices to add forwarding ports on the modem's routing at will.
* Disable remote wireless management, it allows other people to access
your modems configuration over wireless, it only takes guessing the
* Assuming it's a traditional wireless modem and not 5GHz (I've not used
these, I've not heard great things tbh). Set the wireless channel to
something other than 1 and 6, they're common channels and wireless
modems in the same street will war with eachother leading to flakey
In terms of ISP, I'd maybe check uSwitch for who'se got the best
customer rating and is reasonably priced. I'm with my Electricity
supplier (SSE) and they've been pretty solid, so maybe you could get a
package with whoever you're with (makes the bills a bit less fragmented
imo). Although main problem is contract lock-ins and being stuck with
someone rubbish like BT, Sky or Virgin. Talk Talk will be initial pain,
but if you pressure them they get it sorted eventually.
Hope this is helpful,
