I am attempting somewhat of the same, so would appreciate any comments
on this:

I have a BT Homehub, with two wired machines hanging on it. Also have
an old WRT54g down the hall that repeats the Homehub wireless (with
SVEAsoft firmware) to my daughter's room. It's decidedly slow and
cantankerous.

I have a chance to get a Linksys Wireless N Router (not a modem router)
VERY cheaply from someone who bought it and can't use it.

Was wondering about the feasibility of this: Turn off wireless on the
Homehub, wiring the Wireless N router to the Homehub and having the
Wireless router do all the work with wireless and wired. Does the
Homehub have to do all the DHCP work itself? Or am I just asking for
trouble here? Point was to use "N" with a new "N" card in her machine
to see if the reception is better down the hall and to get rid of the
WRT54g in the hallway.

thanks

I'm sure you can leave the HomeHub router's DHCP server turned on (for wired
conections including to the Linksys Wireless N router acting as access
point) and turn off just its wireless access point. Then plug the Linksys
into the Homehub: if you use one of the LAN ports then you don't need to
turn off NAT and DHCP; if you use the WAN port (*) then turn off the
Linksys's NAT and DHCP.

(*) I assume by "not a modem router" you mean a cable router with Ethernet
WAN input rather than phone line ADSL input.

Also telephone line to telephone line. Which means for every direct hit
there's a lot more who suffer damage short of that full treatment.

Some feel it pointless to attempt any form of lightning protection,
since you'll always lose a face-to-face confrontation with Mr. Thor.
However, that forgets those hundred odd nearby whose equipment might
well survive if properly protected, while their neighbour's equipment is
tuned to certain toast, protected or not.

When my Internet service was via ISDN, a lightning strike a few houses
away knocked out my ISDN NTE, left the router plugged into that intact, but
knocked out 3 of the ports on an 8-port switch plugged into the router.
As I had no protection, I felt myself lucky it didn't do more, and that
some protection might well have stopped such low-level collateral
damage.

I'd find it difficult to properly risk assess how the cat5 to the
outbuilding ranks alongside all the other routes open to lightning at
various different levels (from direct hit to distant tickle).

Fine until (from experience) you have a nearby lightning strike.
A few mega-amps flowing through ground resistance can
produce a substantial voltage difference between buildings,
write off the PC's, and most of the networking stuff.
Another problem may be are the buildings on the same phase?
If not safety considerations arise under fault conditions.
Fibre is the preferred solution.
---------
Technical Description: Dynamode RJ-45-FIBRE OPTIC MEDIA
CONVERTER (HALF DUPLEX) - TT-TF ( MEDIA CONVERTERS)
Fibre-optic input support cable distance up to 2Km
Support ST or SC fibre connector
Unshielded RJ45 connectors for twisted pair port
Support diagnostic LEDs for easier troubleshooting
DTE and HUB connector (RJ45) support
Circa 60 quid each end, plus the fibre, for peace of
mind. Vendor says you can pay by PayPal.

You might find a better price if you search around.

Frankly a lightning strike is all bets off everywhere.

Happened to me.

Most of the mains wiring was arced over, various bits of various
computery and home entertainment stuff fried.

Burn holes in carpets. Sockets blown out of walls..

House was totally rewired as a result (insurance insisted)

Cat 5 is fine. You are probably going to lose the switches at each end,
but that's what inusrance is for. Still way cheaper than fibre.

If your phone comes in on the overheads, its a far more tempting target
for Mr Thor.

That means kiss your router/modem goodbye, and the motherboard on the PC
its connected to probably..and after that the current will dance from
cable to cable..

I wouldn't want the secondhand DLSLAM either from BT...

I did say nearby, not a direct lightning strike.
The nearest estimate (from being the local lightning
sink, based on several strikes) is that the differential
between buildings is 80-100V. Some equipment
may suffer from the electromagnetic pulse acting
on ground loops.
With proper precautions, learning from experience,
you can minimise, but not totally eliminate disruption.
It costs a little extra, but is a small price to pay,
compared with taking out most of the PC's and
other kit in a terminal room.
With regard to BT it did take 4 days to replace most
of the cards in their PABX, which is when we found
that in a crisis BT has generous stocks of exchange
cards if you buy a BT PABX.
You can terminate fibre yourself, but pre-terminated
fibre is not prohibitive nowdays, and it does come
tested, so it's plug in and go.
