BT Infinity Hub5 and DHCP IP Address Win XP

I have been using BT Hub 3- P5N9 which was not very fast.
Whenever I start my computer the DHCP IP Address automatically loaded
was 192.168.1.64 with NO problem to connect to the internet.

I have now BT Hub5-2WPR which automatically loaded the DHCP IP Address
169.254.137..91 and it does not connect to internet.
Answer comes "Limited mobility or no connection".

I looked up into our old laptop where the same hub is using the DHCP address
192.168.1.67 for wireless purpose. I tried that one for our desktop computer
and surprised that it did connected to internet but very very slow.

I understand that this hub is reasonably fast so there should be a suitable
code for DHCP IP Address to connect and work properly.

There are lot of expert persons on this group and some of them may be quite
familiar with BTHomeHub5 who can help me for the correct address.

I shall be very grateful for advice?

Undoubtedly a British respondent will know the exact answer.

Does BT have a user support forum ? You could try posting
your query there as well.

I would offer the following tips to get you started.

1) Look for a user manual in the box. Usually, the IP address
of the unit will be listed in there. As well, a default
account name ("admin") and password, may be listed next to
the IP address information. You need that to get into
whatever "dumbed down" setup screen they offer.

In addition, some of these routers, also support a "symbolic"
address. The manual may say to type something like this
into a browser. The router translates this into the numeric
value and then acts on it. So rather than give a number,
sometimes the value is symbolic and relies on DNS translation
inside the router.

2) If for some reason, the unit was "used", it could have been
assigned another starting address. You want to enter the web setup
screen, so you need to know what address to use to get there.
On some of these boxes, there will be a reset button, to return
the unit to default settings. And unlike retail router boxes,
a BT device is likely to be "Locked down". That means, if you
reset the box, it doesn't give you any "magic advantage" over
the BT settings. Most of these boxes support multiple levels
of passwords. A box coming from BT, should not have full admin
access to every function. This is to reduce tech support phone
calls, caused by users "shooting themselves in the foot".

After the reset, things like DHCP should be enabled by default.
You should get an address in the unroutable range (192.168.x.x
or 10.x.x.x ranges). These are home LAN addresses, not your
single WAN address on the Internet side.

When you see 169.254.x.x , that is an APIPA address. It means
the computer was not able to access the DHCP server on the new
BT box.

Now, it could be, that the Ethernet connection to the new BT
box, is working, and that entering the IP address in your
browser, to reach the BT box setup screen, will still work.
So you don't necessarily have to override the 169.254.x.x you
got. You should though, check the network settings of your
current connection, to see if the wire is even connected to
the box. For example, if the BT hub had a dirty Ethernet
connector, it might prevent electrical contact. When that
happened to my new motherboard here, I inserted and removed the
Ethernet cable five times, to allow natural wiping action
to clean the connector contacts. (Dirt like this is caused
by the water-based wash at the factory - if they didn't stick
a rubber plug in the RJ-45 connector hole, some wash residue
ends up drying on the connector pins.)

In any case, generic instructions for new boxen:

1) Use an Ethernet connection for initial setup. That's
normally the most reliable means. Getting there over Wifi,
is less likely to happen.
2) If the box is "used", consult the manual for a reset procedure.
In some cases, the reset button must be held down for up
to 30 seconds, until a specific LED on the box starts to flash.
That is supposed to indicate that the "reset operation has taken
effect".
3) Now, try and reach the well-known address in the manual.

And if the new product came with a software CD, there might even
be a canned setup routine that runs from the CD.

When my $300 router box broke some number of years ago, I was
able to find a "ping" utility, that would scan the 192.168.x.x
and 10.x.x.x ranges, looking for a response. So worst case, if
I had to, I would find a copy of that program, and ping the
crap out of the box, to try and find an address. I left that
running over night, and it got no response at all, indicating
I was out $300. You can't re-flash the box, unless you
know the address and can TFTP to it. So I was in no position
to try "resuscitation".

I would also use my Marvell NIC chip, with VCT (Virtual Cable Tester).
In the event a wire or pin is broken on the Ethernet connector,
the VCT feature of some Marvell NIC chips, can be used to test
the wiring. And actually tell whether all the wires/pins
are touching. That's how I was able to figure out one pin out
of the eight pins, was not touching. Marvell VCT told me
"one pair is open circuit". Marvell VCT uses TDR pulses, to
sense whether each of the four wire pairs, is terminated by
the correct characteristic impedance. It can tell if a pair
is shorted, open circuit, or "just right". It's a great feature,
but not all that common.

Anyway, that's a few things you can work on, until
the real expert arrives.

"Press the Restart button and release it when the Power light
turns orange.

Your Hub will restart and the Power light will glow steady blue.

If it’s still red, reset your Hub using a paper clip to press the
recessed Reset button on the back of your Hub for a few seconds.

If this doesn’t fix it, call us on 0800 111 4567. We’re not so
busy and can help you much faster if you call between 10am and 6pm.
Make sure you’re next to your Hub with a PC or device if you call.
"

By the way, I think the four characters at the end of the product
name are your SSID. And will not match any other user's description.
So your box is just "BT Hub5". The other characters are superfluous
when describing the thing.

"Reseting the Home Hub" - shows the ole paper clip trick...

169.254.x.y is IP AutoConfiguration in action.

This means that the Ethernet adapter saw that an Ethernet cable was attached
and so it made a DHCP request but the request was not answered. No answer,
no IP address was assigned and thus the OS auto-assigned a 169.254.x.y
address.

The word "hub" is used. A hub is a multi-port ethernet repeater. Thus it
is unable to do Full-Duplex and depending on its capabilites may not not
perform auto configuration. Thus the node trying autto-negotiate speed and
duplex fails, and thus a 169.254.x.y address.

So... Try forcing the node to use 100Mb/s half-duplex or 10Mb/s
half-duplex. Then it won't try to auto-negotiate and it will just use that
speed and link-up and hopefully now get an IP from the DHCP server.

"Home Hub" is a trade name, referring to an ADSL modem/router
offered by BT. It could actually be engineered by BT staff,
and manufactured by someone else. In discussion threads, BT
give the impression they run a lab for at least doing
integration and making changes to firmware.

OK - Thanx.

However the suggestion still stands. The ONLY difference is IFF this is a
SOHO Router with multiple LAN ports on a Ethernet switch, one may also try
forcing 100Mb/s Full-Duplex and 10Mb/s Full-Duplex besides half-duplex
modes.
