Re: Weird IP address picked using DHCP

Yep. And if that helps, replace the wireless router/access point with a

I am pleased with our Buffalo (running DD-WRT firmware), BUT I have
also had this happen at least once with the Buffalo.

It was a Belkin pcmcia adapter that, after working for months,
suddenly could not get a lease anymore. Assigning an IP address did
not help. No ping to the router. Rebooting the router did not help.
Then, installing the same adapter on a different pc at the same
location, it worked ! Reinstalling a different version of the adapter
driver on the problem pc seemed to be what fixed it.

Perhaps it's better to say that this was the time that rebooting did
not help. There have been other times/problems when rebooting did the
trick. This time I attributed the problem to the laptop going in and
out of standby frequently during a lease, sometimes very roughly,
while downloading. If I remember correctly. Something about that
adapter on that pc with that driver installation got skewed, or looked
wrong to the router.

Since you got your mom's to work again briefly with an assigned
address, then it broke again, you might ask your mom about how they
manage shutdown/standy/hibernate for their pcs. Question what they
are they doing in that dimension and maybe change it to hard
shutdowns?

Perhaps, just as John says, it is an indication that her router's
firmware is not working right...

Oh, one more thing, since you are not present to solve problems, you
might want to make sure there is an ethernet cable alternative as a
backup when the wireless fails. Even if they have to temporarily run
the cable through the hallway or something, at least they can get
online.

Cheers,

Yep, I've got her using an ethernet cable as a temporary solution
which works fine. I guess I'd be a little surprised if it was a
router problem given that my Dad's laptop connects without any
problems. My gut feel is that it is something to do with her laptop -
whether it's a problem with the installation of the adapter or some
other conflict or whatever. I will get her to check the standby issue
stuff - I hadn't even considered that as a potential cause. I've got
her to reboot everything to see if that worked, but she's had no joy
with that. It's just all very irritating because I tested it before I
left and it was working fine, so I know that it CAN work. I've got to
the point where I've suggested she get someone to come out and have a
look at it (much cheaper than flying me back for a weekend when I
certainly can't promise that I can do anything that she hasn't!).
She mentioned last night that her laptop didn't even detect that our
network was within range (usually it detects it, but can't assign an
address for whatever reason). I find this very weird since at the
moment, her laptop is within a metre or so of the router! I know this
is stupid, but could there be any issues from being TOO close?! Or
maybe having some other sort of equipment around that might be
interfering with the signal and creating too much noise. I know I'm
reaching here...
Anyway, thanks for all your suggestions guys. I know wireless
networks can be a bit funny at the best of times, but will keep
plugging away.
